You are using your laptop on the company network. In your web browser, you type www.google.com and press Enter. The computer will not find Google. You open the browser on your phone, and using your cellular connection, you can open Google without a problem. Your laptop finds internal servers and can print without any issues. What is the most likely reason you can’t open Google?
A. DNS server problem
B. DHCP server problem
C. Missing subnet mask
D. Duplicate IP address
A. DNS server problem
Companies tend to use their own private DNS servers for security and performance. Your laptop is using the company network, and therefore, the company DNS server. If there was a problem with the company’s DNS server, your laptop would be unable to access the internet using domain names, but your phone (using a cellular connection which wouldn’t connect to the company’s DNS server) would have no problems.
If the DHCP server were down, you likely wouldn’t have an IP address, subnet mask, or gateway, meaning you wouldn’t be able to access anything on the network. Since you can access internal resources, DHCP is not the issue.
A missing or incorrect subnet mask would prevent communication with other network segments. Since you can access internal resources, your subnet mask is properly configured.
If you had a duplicate IP, you would likely experience network conflicts, random disconnections, or no connectivity at all. Since you can access internal resources but not external ones, an IP conflict is unlikely.
Which of the following network connectivity devices operates at Layer 2 of the OSI model?
A. Hub
B. Switch
C. Cable
D. Router
B. Switch
A network hub operates at Layer 1 (the Physical Layer) of the OSI model, simply transmitting data received at one port to all other ports without any intelligence or filtering.
Cables, as physical transmission mediums for data, belong to the Physical Layer (Layer 1) of the OSI model.
In the OSI model, routers operate at Layer 3, the Network Layer, facilitating communication between different networks by using IP addresses to route data packets.
Which TCP/IP protocol is used to provide shared access to files and printers on the network?
A. FTP
B. SSH
C. SMB
D. SMTP
C. SMB
Server Message Block
SMB is a network protocol used for sharing files, printers, and other resources between computers on a network. It’s a client-server protocol where clients request services and servers respond.
What port does the Telnet protocol use?
A. 21
B. 22
C. 23
D. 25
C. 23
What port does the SSH protocol use?
A. 21

Which network connectivity device does not forward broadcast messages, thereby creating multiple broadcast domains?
A. Bridge
B. Hub
C. Switch
D. Router
D. Router
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.
Your company just expanded and is leasing additional space in an adjacent office building. You need to extend the network to the new building. Fortunately, there is a conduit between the two.

A. CAT-5e
B. CAT-7
C. CAT-8
D. MMF
D. MMF
Multimode Fiber
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.
Which networking device is capable of reading IP addresses and forwarding packets based on the destination IP address?
A. Hub
B. Switch
C. NIC
D. Router
D. Router
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.
When troubleshooting a network connectivity issue, you discover that the local computer has an IPv4 address of 169.254.2.2. What do you immediately know about this local computer?
A. It is working fine.
B. It has an invalid IP address.
C. It can’t find a DHCP server.
D. It Isn’t on the network.
C. It can’t find a DHCP server.
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.

A. 255.0.0.0
B. 255.255.0.0
C. 255.255.255.0
D. 255.255.255.255
B. 255.255.0.0
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.
Which TCP/IP protocol uses port 445?
A. FTP
B. SSH
C. SMB
D. SNMP
C. SMB
Server Message Block
A network communication protocol that enables shared access to files, printers, and other resources on a network.
For IPv6, which of the following statements are true? (Choose two.)
A. Each IPv6 interface can have only one address.
B. Each IPv6 interface is required to have a link-local address.
C. IPv6 addresses are incompatible with IPv4 networks.
D. IPv6 does not use broadcasts.
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.
Which network connectivity device is seldom used in modern networks, except to extend a network?
A. Hub
B. Router
C. Bridge
D. Switch
A. Hub
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.
There is a TCP/IP protocol that should only be used locally because it has virtually no security. It may be used as a part of a preboot execution environment (PXE) or with thin clients booting from a network drive. It uses very little memory and is good for transferring boot files or configuration data between computers on a LAN, and it is connectionless. Which file transfer protocol is this?
A. TFTP
B. FTP
C. FTPS
D. SMTP
A. TFTP
Trivial File Transfer Protocol
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.
Which networking device has multiple ports, each of which is its own collision domain, and examines the header of the incoming packet to determine which port the packet gets sent to?
A. Hub
B. Bridge
C. Switch
D. Router
C. Switch
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.
What marks the boundary of an IPv4 broadcast domain?
A. Hub
B. Switch
C. Router
D. Modem
C. Router
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.
You are installing an 802.11n Wi-Fi network with five wireless access points. The access points are set up so their ranges overlap each other. To avoid communications issues, what principle should you follow when configuring them?
A. Configure all access points to use the same channel.
B. Configure all access points to use adjacent channels.
C. Configure all access points to use nonoverlapping channels.
D. Channel configuration will not cause communications issues.
C. Configure all access points to use nonoverlapping channels.
You have been asked to install a Wi-Fi network in a building that is approximately 100 meters long and 25 meters wide. Because of cost considerations, you will be using 802.11ac. At a minimum, how many wireless access points will you need?
A. Two
B. Three
C. Four
D. Six
B. Three
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.
You are configuring a wireless 802.11ax router. The office manager insists that you configure the router such that traffic from her computer receives higher priority on the network than other users’ traffic. Which setting do you need to configure to enable this?
A. QoS
B. UPnP
C. Screened subnet
D. Port forwarding
A. QoS
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.
Your network is currently running a mix of 802.11b and 802.11g devices. At the end of the year, you have extra budget to upgrade some, but not all, of the wireless infrastructure. You want to upgrade to the newest technology possible but still maintain backward compatibility. Which standard should you choose?
A. 802.11g
B. 802.11ac
C. 802.11ax
D. 802.11r
C. 802.11ax
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.
Which of the following shorthand notations corresponds to the CIDR subnet mask 255.255.224.0?
A. /19
B. /20
C. /21
D. /22
A. /19
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
You are configuring hosts on a network running IPv4. Which elements are required for the computer to connect to the network?
A. IP address
B. IP address and subnet mask
C. IP address, subnet mask, and default gateway
D. IP address, subnet mask, default gateway, and DNS server address
B. IP address and subnet mask
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.
You work at a tech support company and a customer called reporting that they received an error, something about a duplicate IP address. Why are they getting this message? (Choose two.)
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.
C. A PC is manually configured with an IP that is not in the DHCP scope.
D. None of the PCs have been manually configured.
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.
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.
Which obsolete Wi-Fi encryption standard uses a static key, which is commonly 10, 26, or 58 characters long?
A. WPA3
B. WPA2
C. TKIP
D. WEP
D. WEP
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.
Because of a recent security breach, your IT team shut down several ports on the external firewall. Now, users can’t get to websites by using their URLs, but they can get there by using IP addresses. What port(s) does the IT team need to open back up to enable Internet access via URLs?
A. 20/21
B. 53
C. 67/68

A. DNS
B. SSH
C. SMB
D. NetBT
D. NetBT
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.
When setting up a small office, home office (SOHO) network, how do the end-user devices know what IP address they need to use to connect with the network?
A. The network switch broadcasts configuration settings.
B. Devices utilize service location protocol.
C. The NIC is set with a static address or DHCP-served.
D. End users configure IP addresses as needed.
C. The NIC is set with a static address or DHCP-served.
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.
What Is the most likely way for a homeowner’s IoT devices to connect to their wireless network?
A. DNS
B. AD
C. SSO
D. DHCP
D. DHCP
DHCP = Dynamic Host Configuration Protocol
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.

A. IDS works both on a host and a network.
B. IDS will not actively alert on suspect activity.
C. IPS works in pairs.
D. IPS will actively react to suspect activity.
D. IPS will actively react to suspect activity.
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.
Managing security on your growing network has become difficult, so you ask your peers what they are doing to manage their networks. They recommend a device that will allow you to manage your security in one place. What have they recommended?
A. IDS
B. IPS
C. UTM
D. UTP
C. UTM
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.

Your network admin needs to add a computer to an IPv6 subnet. Which of the following IPv6 addresses is on the same subnet as 2601:0:0:0f:1a:308c:2acb:fee2?
A. 2601::0f:308c:47:4321
B. 2601::0f:ab:cd:123:4a
C. fe80:ab:bc:0f:1a:308c:2abc:fee5
D. 2601:0:0:0x::2acb:ac01
B. 2601::0f:ab:cd:123:4a
IPv6 addresses that share the same first 4 hextets are on the same subnet.
Dylan is troubleshooting his IPv4 network. The network’s subnet mask is 255.255.192.0. Which of the following IP addresses is not on the same network as the others?
A. 130.200.65.5
B. 130.200.130.1
C. 130.200.100.4
D. 130.200.125.5
B. 130.200.130.1
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.

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.
What is the interface ID of the IP address 2001::1a3:f1a:308:833?
A. 2001:0:0:0:
B. 2001
C. 1a3:f1a:308:833
D. 833
C. 1a3:f1a:308:833
The last four groups in an IPv6 address are the interface ID. The interface ID is therefore 1a3:f1a:308:833.
