Question 91

A technician is setting up a workstation. Which of the following settings should the technician configure to ensure that users can connect to the network? (Choose three.)

A. APIРА

B. Gateway

C. IP address

D. Subnet mask

E. Static routes

F. UPnP settings

G. NAT rules

H. MAC filters

Show Answer

Correct Answer: B, C, D

Explanation:
A workstation requires a valid IP configuration to communicate on a TCP/IP network: an IP address identifies the host, a subnet mask determines the local network, and a default gateway enables communication beyond the local subnet. The other options are not fundamental workstation network settings for basic connectivity.

Question 92

A technician installs an upgraded wireless access point. The technician then notices the activity light comes on briefly and turns off. The access point continues to exhibit this behavior repeatedly and does not come online. Which of the following is the most likely cause of this issue?

A. High latency

B. Port flapping

C. External interference

D. Channel conflict

Show Answer

Correct Answer: B

Explanation:
Repeatedly powering up enough to briefly show link/activity and then dropping offline is most consistent with a network port repeatedly transitioning between up and down (port flapping). High latency, RF interference, or channel conflicts can degrade connectivity but would not typically cause this cyclical link-up/link-down behavior preventing the access point from coming online.

Question 93

A technician needs to update a web server’s IPv4 address in a DNS server. Which of the following records should the technician update?

A. AAAA

B. MX

C. CNAME

D. A

Show Answer

Correct Answer: D

Explanation:
An A (Address) record maps a hostname or domain name to an IPv4 address. AAAA records map to IPv6 addresses, MX records specify mail servers, and CNAME records create aliases to canonical names rather than directly storing an IPv4 address.

Question 94

Which of the following connector types is associated with coaxial terminations serving cable internet deployments?

A. DB9

B. ST

C. F-type

D. RJ45

Show Answer

Correct Answer: C

Explanation:
F-type connectors are the standard threaded coaxial connectors used for CATV and cable internet (DOCSIS) deployments. DB9 is a serial connector, ST is a fiber-optic connector, and RJ45 is used for Ethernet twisted-pair networking.

Question 95

A user can connect their laptop to the internet in the main office. However, when the user places the laptop on top of a motor on the factory floor, there is no internet connectivity. Which of the following is the most likely cause of this issue?

A. Jitter

B. Insufficient power levels

C. External interference

D. High latency

Show Answer

Correct Answer: C

Explanation:
Placing the laptop on top of an industrial motor introduces electromagnetic interference (EMI), which can disrupt wireless network signals. Jitter and high latency are network performance issues rather than location-specific signal loss, and insufficient power levels do not fit the scenario described.

Question 96

Which of the following is a characteristic of an NVMe drive?

A. M.2 interface

B. 3.5in (8.9cm) external

C. 7,200rpm

D. Molex connector

Show Answer

Correct Answer: A

Explanation:
NVMe is a storage protocol designed for PCIe-based SSDs. A very common form factor for NVMe drives is the M.2 interface. The other options describe traditional hard drive characteristics (7,200rpm, 3.5-inch) or an older power connector (Molex), none of which are defining characteristics of NVMe drives.

Question 97

A user is having trouble with the location services on their smartphone. Location-based applications show incorrect positions when the user is traveling. This issue affects the user's ability to navigate and use location-dependent applications. Which of the following is the best way to resolve this issue?

A. Downloading a third-party mapping application

B. Resetting the network settings

C. Enabling Wi-Fi to assist GPS

D. Restarting the smartphone

Show Answer

Correct Answer: C

Explanation:
Enabling Wi-Fi-assisted location (high accuracy mode) improves positioning by combining GPS with nearby Wi-Fi networks and cellular signals, which is especially helpful while traveling or in areas where GPS alone is less accurate. Restarting may temporarily resolve glitches but does not directly address location accuracy. Resetting network settings is more disruptive and not the best first solution, and using a different mapping app does not fix the underlying location service.

Question 98

Which of the following tools is best to track where an Ethernet cable is patched?

A. Crimper

B. Punchdown tool

C. Cable stripper

D. Toner probe

Show Answer

Correct Answer: D

Explanation:
A toner probe (tone generator and probe) is used to trace and identify Ethernet cable runs and determine where a cable is patched or terminated. A crimper attaches connectors, a punchdown tool terminates wires onto punchdown blocks, and a cable stripper removes cable insulation.

Question 99

Which of the following virtualization technologies is best suited for running microservices?

A. Containers

B. VDI

C. Type 2 hypervisors

D. Type 1 hypervisors

Show Answer

Correct Answer: A

Explanation:
Containers are the preferred virtualization technology for microservices because they are lightweight, start quickly, share the host OS kernel, and provide consistent, portable environments for independently deployable services. VDI is for desktop virtualization, while Type 1 and Type 2 hypervisors virtualize entire machines and are generally heavier than containers for microservice workloads.

Question 100

Which of the following allows a physical server to host multiple virtual machines?

A. Cross-platform virtualization

B. Hypervisor

C. Sandbox

D. SaaS

Show Answer

Correct Answer: B

Explanation:
A hypervisor (virtual machine monitor) is the software or firmware layer that enables a single physical server to create, run, and manage multiple virtual machines by abstracting and allocating the underlying hardware resources. The other options do not perform this core virtualization function.
