Question 11

Which of the following cable types is used to connect a display?

A. DVI

B. RJ45

C. SATA

D. USB 1.1

Show Answer

Correct Answer: A

Explanation:
DVI (Digital Visual Interface) is specifically designed to transmit video signals from a computer or other source to a display. RJ45 is for networking, SATA is for internal storage devices, and USB 1.1 is a general-purpose data interface not primarily used as a display cable.

Question 11

Which of the following allows an organization to provide remote desktop resources without providing physical workstations to its users?

A. RMM

B. SaaS

C. VDI

D. Containers

Show Answer

Correct Answer: C

Explanation:
VDI (Virtual Desktop Infrastructure) delivers full desktop environments from centralized servers to users over the network, allowing access to remote desktop resources without issuing physical workstations. RMM manages devices, SaaS provides applications (not full desktops), and containers package apps rather than user desktops.

Question 12

A user asks a technician for assistance with a printer that has stopped printing. The user states that the print jobs are generated from a website and are difficult to re-create. When the technician remotes into the user's computer, they can see many jobs in the queue. The issue persists after the user performs a hard reset of the printer. Which of the following will most likely fix the issue?

A. Restarting the print spooler service on the local computer

B. Deleting all the jobs and having the user restart their computer

C. Making sure the printer is using the latest PCL driver

D. Updating the manufacturer's firmware on the printer

Show Answer

Correct Answer: A

Explanation:
The printer has many jobs stuck in the queue, and a hard reset of the printer did not resolve the issue, indicating the problem is likely on the computer rather than the printer. Restarting the print spooler service clears and resets the print queue without requiring the user to re-create difficult web-based print jobs. The other options either risk losing the jobs or address driver/firmware issues that are less likely given the symptoms.

Question 12

Which of the following will most likely be used in a testing environment to execute unauthorized code?

A. Virtual machines

B. Hybrid cloud

C. Load balancers

D. Application gateways

Show Answer

Correct Answer: A

Explanation:
Virtual machines are commonly used in testing and sandbox environments because they provide isolation from the host system. This isolation makes them suitable for safely executing untrusted or potentially unauthorized code without impacting production systems. The other options are infrastructure components not intended for code execution testing.

Question 13

Which of the following network technologies is used for the operation of physical access control systems?

A. 802.1Х

B. VPN

C. GPS

D. RFID

Show Answer

Correct Answer: D

Explanation:
Physical access control systems (e.g., door badges, proximity cards) commonly use RFID to identify and authenticate users at physical entry points. 802.1X and VPN are logical/network access controls, and GPS is for location tracking, not access control.

Question 13

Which of the following should a technician check when the display of a computer is flickering?

A. LCD type

B. Refresh rate

C. Screen resolution

D. Pixel density

Show Answer

Correct Answer: B

Explanation:
Screen flickering is commonly caused by an incorrect or incompatible refresh rate. Adjusting the refresh rate to match the display’s supported frequency typically resolves flicker, whereas LCD type, resolution, and pixel density do not directly cause flickering.

Question 14

A user reports slow performance when saving documents locally on a computer. A technician reviews the logs and notices entries showing S.M.A.R.T. errors. Which of the following actions should the technician take next?

A. Reseat all SATA cables.

B. Replace the hard drive.

C. Defragment the hard drive.

D. Run Disk Cleanup.

E. Install a heat sink on the hard drive.

Show Answer

Correct Answer: B

Explanation:
S.M.A.R.T. errors indicate the hard drive is predicting imminent failure due to detected hardware problems. The appropriate next action is to replace the hard drive, as maintenance tasks like defragmentation, disk cleanup, reseating cables, or adding cooling will not resolve an impending drive failure.

Question 14

A technician is unable to join a computer to the domain. The technician runs ipconfig and gets the following output: Which of the following is the most likely cause?

A. The subnet mask is incorrect.

B. NetBIOS is enabled.

C. DHCP is enabled.

D. DNS servers are manually set.

Show Answer

Correct Answer: D

Explanation:
Joining a computer to an Active Directory domain requires proper DNS name resolution to locate a domain controller. If DNS servers are manually set to non-AD DNS servers, the client cannot resolve the domain or locate the domain controller, causing the join to fail. The other options would not typically prevent domain joining in this scenario.

Question 15

A user reports that a laptop runs very slowly when documents are opened and saved. The user got the laptop within the past year. A technician finds the following specifications for the laptop: Intel Core i5-1235U - Windows 11 Home - Intel Iris Xe Graphics - 1TB 7200RPM 16GB: 2 x 8GB DDR4 2666 The technician thinks a minor upgrade should solve the slow performance issue. Which of the following components should the technician install?

A. Gaming GPU

B. i7 CPU

C. 64GB RAM

D. 2.5 SATA SSD

Show Answer

Correct Answer: D

Explanation:
The laptop already has a modern i5 CPU and sufficient RAM for normal document work. The major performance bottleneck is the 1TB 7200RPM mechanical hard drive, which causes slow opening and saving of files. Replacing it with a 2.5-inch SATA SSD would significantly improve boot times, file access, and overall system responsiveness with a minor upgrade.

Question 15

Which of the following cloud characteristics allows local folders to contain updates that are made by users on other devices?

A. Network share

B. Synchronization

C. Availability

D. Metered utilization

Show Answer

Correct Answer: B

Explanation:
Synchronization enables cloud services to automatically propagate changes made on one device to local folders on other devices. This allows users to see updates across devices. The other options do not describe automatic update propagation.
