1101 Book Test Qs Flashcards

Question

Which network connectivity device does not forward broadcast messages, thereby creating multiple broadcast domains? ## Footnote A. Bridge B. Hub C. Switch D. Router

Answer 1

D. Router ## Footnote A broadcast message is a data packet sent to all devices on a network (or a specific network segment). Routers are designed to route traffic between different networks and do not forward broadcast messages. A broadcast message sent on one network segment does not get forwarded to another segment by a router, which effectively creates separate broadcast domains. By separating broadcast domains, routers help reduce unnecessary network traffic and prevent broadcasts from impacting other parts of the network.

Answer 2

D. MMF | Multimode Fiber ## Footnote For Ethernet networking, MMF supports up to 550 meters at 1 Gbps or 300–400 meters at 10 Gbps. CAT-5e, CAT-7, and CAT-8 Ethernet cables have distance limitations well below 300 meters.

Answer 3

D. Router ## Footnote A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.

Answer 4

C. It can't find a DHCP server. ## Footnote The IP address 169.254.2.2 falls within the APIPA (Automatic Private IP Addressing) range, which is **169.254.0.0 to 169.254.255.255**. APIPA addresses are automatically assigned by Windows and other operating systems when a computer fails to obtain an IP address from a DHCP server.

Answer 5

B. 255.255.0.0 ## Footnote The default subnet mask for Class B networks is 255.255.0.0, or written in shorthand, /16. The default subnet mask for Class A networks is 255.0.0.0, or written in shorthand, /8. For Class C it is 255.255.255.0, or written in shorthand, /24. 255.255.255.255 is an IPv4 broadcast address. As a subnet mask it is represented as /32 (in shorthand) in the classless interdomain routing (CIDR) notation.

Answer 6

C. SMB | Server Message Block ## Footnote A network communication protocol that enables shared access to files, printers, and other resources on a network.

Answer 7

**B. Each IPv6 interface is required to have a link-local address.** 1. In IPv6, every network interface must have a link-local address, which is used for local network communication. 2. Link-local addresses start with FE80::/10 and are automatically assigned, even if no other IPv6 address is configured. 3. These addresses are not routable beyond the local network segment. **D. IPv6 does not use broadcasts.** 1. Unlike IPv4, which relies heavily on broadcasts (e.g., ARP requests), IPv6 eliminates broadcasts to reduce unnecessary network traffic. 2. Instead, IPv6 uses multicast and anycast for more efficient communication. 3. For example, Neighbor Discovery Protocol (NDP) replaces ARP using multicast rather than broadcast.

Answer 8

A. Hub ## Footnote A Hub does not filter traffic or create separate collision domains, unlike a Switch, making it inefficient for modern networks. This leads to high collision rates, especially as the number of connected devices increases. As a result, switches have replaced hubs in most networks. Hubs may still be used in niche scenarios, such as: * Temporarily extending a network when no switch is available. * Network monitoring (via packet sniffing), since hubs forward all traffic to all ports. * Legacy equipment compatibility, where old devices still require hub-based connectivity.

Answer 9

A. TFTP | Trivial File Transfer Protocol ## Footnote B. FTP (File Transfer Protocol) Requires authentication and runs over TCP (port 21). More robust than TFTP but not used for PXE or thin clients. C. FTPS (FTP Secure) Uses encryption (SSL/TLS) for secure file transfers. Not lightweight and not used for PXE or basic LAN file transfers. D. SMTP (Simple Mail Transfer Protocol) Used for sending emails, not file transfers. Runs over TCP port 25, 465, or 587, making it completely irrelevant to PXE or LAN-based file transfers.

Answer 10

C. Switch ## Footnote Multiple Collision Domains: Each port on a switch creates a separate collision domain, reducing network congestion. Unlike hubs, which share a single collision domain, switches allow full-duplex communication between devices. Packet Header Examination: A switch examines the Ethernet frame’s MAC address to determine where to forward the packet. It uses a MAC address table (also called a CAM table) to efficiently route packets only to the intended recipient. Traffic Efficiency: Switches eliminate unnecessary traffic by forwarding packets only to the correct port instead of broadcasting to all devices.

Answer 11

C. Router ## Footnote An IPv4 broadcast domain consists of all devices that can receive a broadcast message sent to the network’s broadcast address. Routers do not forward broadcast traffic from one network segment to another, effectively marking the boundary of a broadcast domain. This helps contain network congestion, as excessive broadcasts can degrade performance in larger networks.

Answer 12

C. Configure all access points to use nonoverlapping channels.

Answer 13

B. Three ## Footnote 802.11ac operates primarily on the 5 GHz band and a single access point (AP) on 5 GHz typically covers around 30 meters indoors, depending on obstacles like walls, floors, and interference. The building is 100 meters long, meaning a single 5 GHz AP cannot cover the entire length. Three APs, evenly spaced every ~33 meters, would provide proper coverage while ensuring sufficient overlap for seamless connectivity. The 25-meter width is manageable with one AP per segment, assuming minimal interference.

Answer 14

A. QoS ## Footnote QoS (**Quality of Service**) refers to a set of technologies and mechanisms used to manage and prioritize network traffic, ensuring critical applications and services receive preferential treatment to optimize performance and reliability.

Answer 15

C. 802.11ax ## Footnote 802.11b and 802.11g both only use 2.4 GHz. 802.11ax is the newest option that supports 2.4 GHz. 802.11g isn't the newest tech. 802.11ac only uses 5 GHz, not 2.4 GHz. 802.11r is a roaming standard, not a Wi-Fi generation.

Answer 16

A. /19 ## Footnote To find the subnet mask number, convert the decimal representation of the subnet mask to a binary representation and then count each “1” in the subnet mask. The total is the subnet mask number. 255.255.224.0 in binary is 11111111.11111111.11100000.00000000 8 + 8 + 3 + 0 = 19

Answer 17

B. IP address and subnet mask ## Footnote The **IP Address** uniquely identifies the device on the network. The **Subnet Mask** defines which portion of the IP address represents the network and which part represents the host. This allows the computer to determine if another device is on the same subnet. A. IP address Incorrect because, without a subnet mask, the device wouldn’t know which network it belongs to or how to reach other local devices. C. IP address, subnet mask, and default gateway Not required for local communication. A default gateway is needed only when communicating outside the local network (e.g., accessing the internet or another subnet). D. IP address, subnet mask, default gateway, and DNS server address Incorrect because a DNS server is not required to connect to the local network. DNS is only needed to resolve domain names (e.g., google.com) to IP addresses for internet browsing.

Answer 18

A. All hosts on a network must have a unique IP address. B. A PC is manually configured with an IP that is in the DHCP scope. ## Footnote A DHCP (Dynamic Host Configuration Protocol) scope is a range of IP addresses that a DHCP server is configured to lease to client devices on a network, enabling automatic IP address assignment and other network configuration parameters.

Answer 19

D. WEP ## Footnote WEP stands for **Wired Equivalent Privacy**, a security protocol for wireless networks that was part of the original IEEE 802.11 standard, aiming to provide a level of security comparable to wired networks.

Answer 20

B. 53 | Port 53 is DNS (Domain Name System) ## Footnote DNS translates domain names (google.com) into IP addresses.

Answer 21

D. Direct packets out the proper port

Answer 22

D. NetBT ## Footnote NetBT, or NetBIOS over TCP/IP, is a network protocol that allows legacy applications using the NetBIOS API to communicate on modern TCP/IP networks. It's essential for integrating older systems and applications that rely on NetBIOS with current TCP/IP networks.

Answer 23

C. The NIC is set with a static address or DHCP-served. ## Footnote A. The network switch broadcasts configuration settings. Incorrect because switches operate at Layer 2 (Data Link Layer) and do not assign IP addresses. They only manage network traffic based on MAC addresses. B. Devices utilize Service Location Protocol (SLP). Incorrect because SLP is used for service discovery (e.g., finding printers or shared resources) but not for IP address assignment. D. End users configure IP addresses as needed. Incorrect because, while possible, most home and small office networks rely on DHCP to automatically assign IP addresses, rather than requiring users to manually set them.

Answer 24

D. DHCP | DHCP = Dynamic Host Configuration Protocol ## Footnote DHCP automatically assigns IP addresses to devices on a network, so homeowners don’t have to manually configure network settings for each IoT device. A. DNS (Domain Name System) – Translates domain names (e.g., google.com) into IP addresses. While important for internet browsing, it does not manage device connections to a wireless network. B. AD (Active Directory) – A Microsoft enterprise-level directory service used for managing users and devices in large organizations. Homeowners don’t typically use AD for IoT devices. C. SSO (Single Sign-On) – A method for user authentication, allowing access to multiple services with one login. While SSO can be used for cloud-based IoT platforms, it is not related to how devices connect to a wireless network.

Answer 25

D. IPS will actively react to suspect activity. ## Footnote An **Intrusion Detection System** (IDS) monitors network traffic for malicious activity and alerts administrators, while an **Intrusion Prevention System** (IPS) actively blocks detected threats, acting as a more proactive security measure.

Answer 26

C. UTM ## Footnote A UTM (Unified Threat Management) appliance combines multiple security functions (like firewall, antivirus, and VPN) into a single device for network protection. A. IDS (Intrusion Detection System) – Detects threats but does not actively block them or manage network security in a centralized way. B. IPS (Intrusion Prevention System) – Can block threats, but it is focused only on intrusion prevention, not overall security management. D. UTP (Unshielded Twisted Pair) – This refers to a type of network cabling, which is completely unrelated to security management.

Answer 27

A. It is a managed switch. D. It is communicating on port 162. ## Footnote A Simple Network Management Protocol (SNMP) trap is unrequested information being sent from an SNMP agent, in this case running on a managed switch. SNMP traps are sent via port 162.

Answer 28

C. WLAN server ## Footnote A. WLAN router – Essential for a WLAN; it connects wireless devices to the network and manages traffic. B. WLAN gateway – A device that connects a WLAN to another network, such as the internet. This could be part of a router or a separate device. D. WLAN client – Any device that connects to a WLAN (e.g., laptops, smartphones, tablets). Clients are essential components of a WLAN.

Answer 29

A. Enable DHCP settings on the router. C. Configure each NIC to obtain an IP address automatically.

Answer 30

B. 2601::0f:ab:cd:123:4a ## Footnote IPv6 addresses that share the same first 4 hextets are on the same subnet.

Answer 31

B. 130.200.130.1 ## Footnote 255.255.192.0 = 11111111.11111111.11000000.00000000 The third octet has two 1s, which means the network is broken into four subnets (00, 01, 10, and 11)(2^x where x = the number of 1s.) 00000000 = 0, 01000000 = 64, 10000000 = 128, and 11000000 = 192. IP addresses within each range would be 0 to 63, 64 to 127, 128 to 191, and 192 to 255. The first and last IP in each range would not be used because they would represent the subnet itself and the broadcast numbers.

Answer 32

B. It converts fiber-optic light signals to electrical (Ethernet) signals. D. It requires external power to work properly. ## Footnote An **Optical Network Terminal** (ONT) is a device that connects fiber optics cables to other wiring such as Ethernet and phone lines by converting the signal from optical to electrical and vice versa.

Answer 33

D. 200 ## Footnote When an IP address and subnet mask are converted to the binary numbers that the computer sees, wherever there is a 1 in the subnet mask, that tells the computer that the corresponding bit in the IP address is part of the network number. Wherever there is a 0 in the subnet mask, the corresponding bit in the IP address is part of the host number. The address in the question, 192.168.2.200/24, is a Class C private address, where, in the subnet mask, the first three octets (24 bits) are all 1s, and the last octet (8 bits) are 0s. So, the first three decimal numbers of the IP address, which is expressed in dotted decimal notation, are the network number, (192.168.2) and the last octet (.200) is the host (individual computer) address. Network numbers will always go from left to right with no breaks between.

Answer 34

C. 1a3:f1a:308:833 ## Footnote The last four hextets in an IPv6 address are the interface ID. The interface ID is therefore 1a3:f1a:308:833. The first three hextets identify the network, and the fourth identifies the subnet. In this example, 2001:0:0 is the site prefix and 0 is the subnet ID. IPv6 addresses do not need a subnet mask like IPv4 addresses do.

A. Increased battery usage B. Increased heat production

Answer 47

C. Install a macOS printer driver on the print server.

Answer 48

C. Printhead D. Tractor feed mechanism ## Footnote **C. Printhead** * In impact printers, the printhead contains pins that strike the ribbon to form characters. * Over time, these pins can get dirty, misaligned, or stuck, so they require cleaning or replacement. * Inkjet printheads also exist but are usually self-cleaning or replaced with the cartridge. **D. Tractor Feed Mechanism** * This is unique to impact printers that use continuous feed paper with holes on the sides. * The tractor feed mechanism guides and pulls the paper through. * Requires cleaning, alignment, and checking for wear—something you don’t do on inkjet printers.

Answer 49

C. PCIe | Peripheral Component Interconnect Express ## Footnote PCIe is a serial bus interface that replaced older parallel bus standards like PCI and PCI-X. PCI is parallel. PCI-X (X for eXtended) is just a longer PCI. Mini-PCI is just a shorter PCI.

Answer 50

B. You can put an x8 card into an x16 slot, but it will run at x1 speed.

Answer 51

A. The CPU must have SLAT. C. The processor must be 64-bit D. You need to enable virtualization in the BIOS/UEFI. ## Footnote SLAT (Second Level Address Translation) is a hardware feature required for efficient virtualization. For Intel processors, this feature is referred to as Intel VT-x with EPT (Extended Page Tables). SLAT is essential for Hyper-V to function properly and provide better performance for virtual machines. Hyper-V requires a 64-bit processor for running virtual machines. The underlying architecture must be capable of handling the larger address spaces and the complexity of virtualization. Virtualization technology (Intel VT-x for Intel processors) is often disabled by default in the BIOS/UEFI. In order to use Hyper-V, you must enable virtualization in the BIOS or UEFI settings.

Answer 52

C. Developing ## Footnote **Processing** – Document data is sent from the computer and prepared for printing by the printer's memory. **Charging** – Prepares the drum with a uniform negative charge. **Exposing** – A laser writes the image onto the drum by discharging areas where toner should stick. **Developing** – Toner is applied to those exposed (discharged) areas. **Transferring** – The toner image is moved from the drum to the paper. **Fusing** – The toner is melted and bonded to the paper. **Cleaning** – Cleans residual toner for the next cycle.

Answer 53

A. It transfers a positive charge to the paper. ## Footnote After the toner image is developed on the drum, it needs to be transferred to the paper. Toner is electrostatically charged and needs to be pulled off the drum and onto the paper. The transfer corona assembly (or transfer roller in newer printers) gives the paper a strong positive charge. **Since toner is negatively charged, this positive charge attracts the toner from the drum onto the paper as it passes through.**

Answer 54

D. Print a test page. ## Footnote **A test page checks several key things:** * Confirms the printer can receive and process print jobs * Verifies correct driver functionality * Confirms connectivity between the computer and printer * Helps identify any print quality issues

Answer 55

B. HVPS ## Footnote The HVPS (High Voltage Power Supply) is the component that converts AC current into high voltage DC, which is used by the charging corona and the transfer corona. The LVPS (Low Voltage Power Supply) provides low-voltage DC power to the printer’s logic circuits, motors, and other components that require low voltage, but not the high voltage needed by the charging and transfer corona. The ACPS (AC Power Supply) isn’t a component in a laser printer The Transfer Corona Assembly is the actual part of the printer that applies the high voltage to the paper during the transfer process, but it is not responsible for converting AC current into usable energy.

Answer 56

D. 28,800 Mbps ## Footnote The number designation of 3600 in DDR4 3600 indicates bus speed of 3,600 MHz. To find the throughput, **multiply the bus speed by 8**. (Why 8? Because DDR memory transfers 8 bytes per cycle (1 byte = 8 bits).) So for DDR4 3600: 3600 × 8 = **28,800 Mbps**

Answer 57

C. PC5 41600 ## Footnote Multiply the 5,200 bus speed by 8 to get the bits per second that can be transferred in and out of the RAM module. The PC5 designation means that it is DDR5, and the 41,600 means that it can (theoretically) transfer 41,600 Mbps (megabits per second).

Answer 58

D. It cools the computer by pulling hot air from inside the case, through the power supply, and blowing it out the back of the power supply, which in turn draws cooler air in through vents in the case.

A. 3 meters ## Footnote USB 1.0 = 3 meters (9.8 feet) USB 2.0 = 5 meters (16.4 feet) **USB 3.0 = 3 meters (9.8 feet)** USB4 = 0.8 meters (2.6 feet)

Answer 63

D. The cards will all operate at the slower speed.

Answer 64

B. A laser reduces areas of the drum from a strong negative charge to a slight negative charge. ## Footnote Toner particles are negatively charged, so they're attracted to the less negatively charged areas.

Answer 65

A. LVPS C. DCPS ## Footnote LVPS (Low Voltage Power Supply) and DCPS (Direct Current Power Supply) convert AC power into DC power that is used to supply the logic circuitry, motors, and other components in the printer. HVPS (High Voltage Power Supply) supplies high voltage to the laser printer's imaging drum, transfer corona, and fusing unit. ACPS (AC Power Supply) is not a component in a laser printer.

A. White/orange, orange, white/green, blue, white/blue, green, white/brown, brown

Answer 68

A. RG-6 ## Footnote RG-8 is primarily used for broadcasting, amateur radios, and antenna feed cable. RG-58 A/U is a type of coaxial cable commonly used in radio communications. RG-59 is commonly used for low-power video and RF signal connections, including in CCTV and audio/video applications.

Answer 69

D. If the replacement cable works, it won't work as well. RG-6 should be purchased. ## Footnote RG-59 can *technically* be used, but it’s not ideal for a long 250-foot run. Over long distances, RG-59 will suffer from more signal loss due to its thinner shielding and lower quality core. So, while it might "work," the signal quality will be degraded, especially for high-frequency signals (like digital TV or internet). Best practice: replace with RG-6 to ensure proper performance.

Answer 70

D. Mini-HDMI

Answer 71

C. DB9 ## Footnote SCSI is parallel, not serial, and was never commonly used for keyboards, mice, or game controllers. PS/2 uses a round 6-pin connector, not a serial connector. Lightning was introduced ***after*** USB.

Answer 72

B. Virtual ## Footnote **Cache** memory is a small, fast memory that acts as a buffer between the CPU and main memory (RAM), storing frequently accessed data and instructions for quicker retrieval, improving overall system performance. **DIMM** and **SODIMM** are physical RAM.

Answer 73

B. mSATA ## Footnote mSATA (**mini-SATA**) is a **small form factor** SATA interface for solid-state drives (SSDs) designed for use in **laptops, ultrabooks, and other space-constrained devices**, offering a compact and relatively fast storage solution.

Answer 74

C. Fibre Channel HBA | HBA = Host Bus Adapter ## Footnote A Fibre Channel HBA enables connectivity and data transfer between devices in an FC-based storage area network (SAN). Fibre is faster than Wi-Fi.

Answer 75

B. 20-pin+4-pin P1 connector C. An ATX12V PSU ## Footnote 20-pin+4-pin P1 connector combines a 20-pin connector and a 4-pin connector to create a 24-pin connection. The ATX12V power supply is a standard that includes the 24-pin P1 connector. A 20-pin P1 connector is older and lacks the additional 4 pins necessary for powering modern motherboards properly. The P4 connector is typically used for providing extra power to the CPU, but it’s not enough on its own to meet the power requirements of a 24-pin motherboard. The ATX12VO (12V-only) standard only provides 12V power to the motherboard and other components and is not compatible with systems that require the full 24-pin P1 connector.

Answer 76

B. That's not the right way to unbox a printer. C. It's better to lay the box on its side and pull the materials out.

Answer 77

B. Secured prints

Answer 78

B. Create virtual machines. ## Footnote **Creating virtual machines** (VMs) addresses all the client's concerns while still maintaining control over the computing environment. **Clusters** improve redundancy and uptime, but they do not reduce space, power, or hardware needs—in fact, they often increase them. **Outsourcing to an IaaS provider** might reduce hardware and power usage, it requires giving up some control—which the client doesn’t want. **Shutting down the nonessential machines** might reduce costs temporarily, but this could affect operations or services. It's a band-aid, not a real solution.

Answer 79

A. Security and confidentiality C. Poor application performance

Answer 80

C. Metered utilization ## Footnote Metered utilization refers to a cloud model where resources (such as computing power, storage, or bandwidth) are allocated and billed based on actual usage. This means the company only pays for what it uses, and the cloud provider can scale resources automatically as demand fluctuates. This approach allows for the company to prepare for surges by ensuring they only pay for extra resources when needed, making it highly adaptable and cost-effective.

Answer 81

C. 5 GB ## Footnote 2 GB to run Windows 10 64-bit + 1 GB to run the OS in the VM + 2 GB to run the software in the VM = 5 GB total.

Answer 82

B. VDI in the cloud ## Footnote **A. On-demand desktop** ➤ This term is vague. It might refer to cloud-hosted desktops, but it's not a specific technology like VDI. **C. Desktop emulation** ➤ Emulating a desktop is more about mimicking another OS or system, not syncing your real desktop across locations. **D. Synchronized folders** ➤ This could sync files (like with OneDrive or Google Drive), but not your full desktop experience (e.g., installed apps, shortcuts, settings).

Answer 83

C. VDI in the cloud ## Footnote **A. IaaS (Infrastructure as a Service)** Gives raw computing resources (like VMs), but not pre-built virtual desktops. You’d still need to manage everything manually. **B. SaaS (Software as a Service)** Delivers applications, not desktop environments. Good for tools like Gmail or Salesforce, but not for managing full desktop OS environments for remote workers. **D. VDI on premises** Offers the same benefits as cloud VDI, but requires you to manage and scale the hardware and infrastructure yourself—which doesn’t align with a mobile, scalable workforce.

B. Replace the laptop with one that has a faster CPU. ## Footnote Upgrading a laptop CPU is generally much more complicated than upgrading a desktop CPU. Laptops are often designed with specific, non-upgradable components, and many factors make it difficult to upgrade the processor, such as the CPU being soldered directly onto the motherboard or the lack of compatibility with a faster CPU.

Answer 91

C. Replace the motherboard.

Answer 92

B. The display has a native resolution of 1920x1080.

Answer 93

B. Bad RAM D. Improperly seated chips ## Footnote **A. Failing hard drive** Usually causes boot errors, read/write failures, or the system hanging—not power loss or shutdowns. You'd often see warning signs, like slow performance or file corruption. **C. BIOS/UEFI misconfiguration** Might prevent the system from booting or cause instability, but it’s less likely to cause completely random shutdowns, especially if nothing was recently changed.

Answer 94

D. The system BIOS completed the POST routine normally.

Answer 95

D. Remove and reinsert the battery.

Answer 96

B. Document and label screw locations. C. Refer to the manufacturer's instructions.

Answer 97

D. Gently shake or replace the toner cartridge. ## Footnote Toner cartridges contain a powder that is used to create the image on the page. Over time, the toner powder can settle unevenly within the cartridge, which can lead to streaks or uneven printing. Gently shaking the toner cartridge helps redistribute the toner powder evenly, which can resolve issues with streaking.

Answer 98

A. Magnetic hard drive

Answer 99

C. Ink Ribbon

Answer 100

D. Add another switch to the network. ## Footnote Adding another switch helps distribute the network traffic more effectively. Adding a hub would likely make the problem worse, not better, because it would increase network traffic without properly managing it.

Answer 101

C. Disable EEE on the switch. ## Footnote EEE, or Energy Efficient Ethernet, is an IEEE 802.3az standard that reduces power consumption in Ethernet networks during periods of low data activity by allowing physical layer devices (PHYs) to enter a low-power idle (LPI) state.

Answer 102

B. Default gateway down ## Footnote The default gateway is a crucial network device that allows devices on a local network to communicate with devices outside of that network, such as the internet or other servers. The problem likely lies with the default gateway being down, which is preventing the network from routing traffic to external destinations, while still allowing local communication like printing.

B. RAM ## Footnote The "UNEXPECTED_KERNEL_MODE_TRAP" error in Windows (often seen as a Blue Screen of Death, or BSOD) is a stop code that typically means the CPU generated a trap (an error) that the kernel wasn't expecting to handle. The most common hardware-related cause is Faulty RAM. RAM issues cause corrupt data to be passed to the CPU. The system expects clean, valid instructions—bad RAM can trigger exceptions the OS isn't prepared to manage. If data in kernel space is compromised, it often causes kernel-mode trap errors.
