Which of the following form factors provides a mini card interface used to connect a laptop’s SSD at higher bus speeds than SATA?
A. 1.8”
B. 2.5”
C. 3.5”
D. M.2
D.
M.2 s a new set of form factors for mini card interfaces.
An M.2 SSD provides a direct interface with the PCI Express bus to provide higher bus speeds than a
SATA connection. M.2 adapters come in four different sizes based on their length.
The one chosen depends on your model of laptop and the space available within the case.
The 80mm variety is the most common one used in modern laptops.
Which of the following types of hard drives would be used in a gaming laptop to increase the system’s boot-up performance while providing a large amount of storage at a lower overall cost?
A. SSD
B. Optical drive
C. Hybrid drive
D. Magnetic drive
C.
A hybrid hard drive (SSHD) is a storage drive that combines the large storage capacity of an HDD with the faster read/write speed of an SSD. The majority of the drive uses a spinning disk and actuator arm, like a traditional magnetic drive, but it also contains a small SSD (solid-state drive) as part of the combined hybrid drive unit. This allows data to be written to either the SSD portion (for data accessed more frequently like the OS and programs) while using the HDD portion to store larger amounts of rarely accessed files (such as photos and video files). Hybrid hard drives constantly monitor the data retrieved from storage, and it automatically determines which data you open the most. It places the files that you use most often on the SSD to read/write that data faster.
You have been asked to set up the email on a corporate laptop. The employees of Dion Training are only allowed to receive their email on one device. The email should be removed from the server’s mailbox whenever the client connects to the server to download the messages. Which of the following mail protocols should you configure to allow an employee to receive their mail on their laptop and meet these requirements?
A. POP3
B. SMTP
C. IMAP
D. HTTPS
A.
You should configure POP3 because the mail is downloaded to the device and removes the mail from the server’s mailbox by default. IMAP does not remove the mail from the server when the client connects but instead maintains a copy on the server indefinitely until the user forces it to be deleted. SMTP is used to send emails, not receive them. HTTPS is used for web browsing, not for receiving emails.
Your firewall is blocking outbound email traffic that is attempting to be sent. Which port should you verify is set to ALLOW in the firewall to ensure your emails are being sent?
A. 22
B. 25
C. 80
D. 143
B.
Email servers rely on port 25 to send emails out of the network.
Which of the following ports is used by the Service Location Protocol when organizing and locating printers, databases, and other resources in a network?
A. 443
B. 427
C. 445
D 389
B.
Port 427 is used by SLP. The Service Location Protocol (SLP) is a protocol or method of organizing and locating the resources (such as printers, disk drives, databases, e-mail directories, and schedulers) in a network. This is an alternative protocol to LDAP in newer networks. While you may not have this port memorized, you should have memorized ports 389, 443, and 445 and identified that they were not associated with printers.
Jason would like the fastest internet available at his house, and he called his local fiber-optic provider. Which of the following offers would provide the fastest service to Jason’s home network?
A. FTTH
B. FTTN
C. FTTC
D. HFC
A.
“Fiber to the X” (FTTx) is commonly used to describe where the fiber connection ends between the service and the subscriber. The closer the fiber is to the user’s network, the faster the service. FTTH (fiber to the house) provides fiber directly to the user’s home network making it the fastest option. Traditionally, you will find 1 Gbps connections or higher with FTTH. FTTN (fiber to the node) or FTTC (fiber to the curb/cabinet) provides fiber only to the local area or neighborhood but then uses copper cabling from the node/cabinet/curb to the home network, which slows down the network (generally, 100-200 Mbps). HFC (Hybrid Fiber Coax) is similar to FTTN/FTTC, except that coaxial cable is used from the cabinet to the home to increase the speed (generally 300-500 Mbps).
Which type of wireless network utilizes the 5 GHz frequency band and reaches speeds of up to 54 Mbps?
A. 802.11a B. 802.11b C. 802.11g D. 802.11n E. 802.11ac
A.
The wireless 802.11a standard uses the 5 GHz frequency band and can reach speeds of up to 54 Mbps. Unfortunately, when this was first released, the radios to operate with this standard were fairly expensive, so it did not sell well or become widespread.
You connect a VOIP device on a user’s desk and need to connect it to a PoE enabled switch located in a communications closet about 150 feet (approximately 50 meters) away. Which of the following cables should you select to connect the VOIP device to the switch?
A. CAT 3
B. Coaxial
C. CAT 6
D. Fiber
C.
Key Term : PoE (Power over Ethernet)
VOIP (Voice over IP) devices that rely on PoE (Power over Ethernet) should use a CAT 5e or CAT 6 cable to make the connection. This allows a single cable (CAT 5e or CAT 6) to carry both the data and the device’s power. Fiber, coaxial, and CAT 3 cables cannot carry power to the VOIP device and cannot be used to meet this requirement. Using a CAT 5e or CAT 6 cable, you can connect two devices of approximately 300 feet (100 meters) without any need to repeat the signal.
Your home network has a wireless access point (WAP) that allows your smartphone and tablet to connect to your internal network. The WAP is connected to a router and a cable modem to provide internet access. A coaxial cable carries the network traffic from the cable modem to the cable company’s central office for transmission to and from the internet. Which of the following types of networks would best describe this network configuration between your home network and the internet through your cable modem connection?
A. PAN
B. LAN
C. MAN
D. WAN
D.
A wide area network (WAN) is a telecommunications network that extends over a large geographical area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits. This is usually a DSL, cable connection, fiber connection, or satellite connection in a home network.
Which type of internet connection is terminated at a local switching center and requires a different type of media between the switching center and the end customer?
A. Fiber
B. ISDN
C. DSL
D. Cable
C.
DSL is a technology used to transmit multimedia traffic at high-bit rates over twisted-pair copper wire (over ordinary telephone lines). This allows the telecommunications company to connect a user’s home to the local switching center using normal telephone lines, then connect that local switching center (using a DSLAM to multiplex the connections) to the central office over a single high-speed cable (such as a fiber connection).
Which type of wireless network utilizes the 2.4 GHz frequency band and reaches up to 11 Mbps speeds?
A. 802.11a B. 802.11b C. 802.11g D. 802.11n E. 802.11ac
B.
The wireless 802.11b standard supports the use of the 2.4 GHz frequency band and can reach speeds of up to 11 Mbps. Even though 802.11a was a faster standard, the 802.11b standard gained more widespread adoption due to the low cost of manufacturing the radios for use in the 2.4 GHz frequency band.
Which of the following is a public IP address?
A. 192.168.1.45
B. 172.18.2.68
C. 10.0.1.45
D. 68.24.91.15
D.
There are three private address ranges. Class A private addresses are in the 10.0.0.0 to 10.255.255.255 range. Class B private addresses are in the 172.16.0.0 to 172.31.255.255 range. Class C private addresses are in the range 192.168.0.0 to 192.168.255.255. Only 68.24.91.15 is outside of these ranges; therefore, it is a public IP address.
You have just set up a Minecraft server on a spare computer within your network and want your friends to connect to it over the internet.
What do you need to configure in your SOHO router to allow your friends to connect to the new Minecraft server you created?
A. Update the firmware
B. Configure port forwarding
C. Enable DHCP
D. Configure your Wi-Fi to use Channel 11
B.
Port forwarding maps one port to another. If you want an external user to be able to access an internal computer or server, you will need to setup port forwarding on your SOHO router to allow your external users to access the server within the internal (private) LAN.
You are trying to send an email to your boss, but it refuses to leave your outbox. You see an error message displayed on the screen that tells you to verify your outbound server settings. Which of the following servers should you configure your email client to use to ensure your emails are being sent?
A. SMTP server
B. SSH server
C. POP3 server
D. DNS server
A.
SMTP is the Sendmail Transfer Protocol. An SMTP server uses the SMTP protocol to send emails from one server to another. If your mail client cannot send an email properly, it is likely an issue with your SMTP server.
You are configuring a new server for a client. The client has purchased five 1 TB hard drives and would like the server’s storage system to provide redundancy and double fault tolerance. Which of the following configurations would BEST meet the client’s requirements?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 10
D.
RAID 10 provides for redundancy and double fault tolerance. RAID 10, also known as RAID 1+0, is a RAID configuration that combines disk mirroring and disk striping to protect data. It requires a minimum of four disks and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved. RAID 5 is a redundant array of independent disks configuration that uses disk striping with parity, but it only provides single fault tolerance. RAID 0 utilizes stripping, so it provides no redundancy. RAID 1 utilizes mirroring, which provides for redundancy and single fault tolerance.
A client has asked you to build a computer to use as part of their home theater system. The HTPC will be used primarily to stream videos in their living room and must have a small form factor to fit into their entertainment center next to their surround sound system. Which of the following motherboards would be the BEST choice for an HTPC system?
A. ATX
B. Mini-ITX
C. ITX
D. Micro-ATX
B.
Mini-ITX is the most commonly used form factor with HTPC systems because they require the smallest fans or passive cooling, which minimizes the noise produced by the system.
Tom, a system administrator, has installed and configured a new domain server for a corporate network. What is the next step that he should perform to allow the company’s employees to access the server on the corporate domain?
A. Install an application
B. Configure access to the file server
C. Install antivirus protection
D. Configure the user’s account
D.
After the server is installed, configured, and setup, a system administrator must create and configure each user’s account to access the domain via their local PC. Each account should be configured using the concept of least privilege to maximize the security of the domain server and the network. After configuring the user’s account, the administrator can install the antivirus, applications, and configure access to the file server.
