A technician has built a new computer. On the initial startup, the computer passes POST but will not turn on the operating system. Which of the following components has failed?

  1. Audio card
  2. CPU
  3. Power supply
  4. HDD

Answer(s): D

Explanation:

Since POST verifies that critical hardware (CPU, memory, motherboard, etc.) is functioning, a successful POST followed by failure to load the operating system points to the storage device - i.e., the hard drive - not providing a boot volume.



A user reports slow internet browsing. The technician finds high CPU and memory usage, and pop-ups occur every minute. Which of the following should the technician do next?

  1. Escalate to the network team to check end-to-end connectivity.
  2. Download and install the latest drivers.
  3. Update the anti-malware signatures and scan the system.
  4. Check the wireless settings and validate the DHCP configuration.

Answer(s): C

Explanation:

High resource usage combined with frequent pop-ups strongly indicates malware or adware infection. Updating your anti-malware definitions and performing a full system scan is the most effective next step to identify and remove malicious software.



Which of the following is the best to use when testing a file for potential malware?

  1. Multitenancy
  2. Test development
  3. Cross-platform virtualization
  4. Sandbox

Answer(s): D

Explanation:

A sandbox provides an isolated environment where you can safely execute and observe a suspicious file’s behavior without risking your primary system.



Which of the following resolutions is commonly known as Ultra HD?

  1. 1920x1080
  2. 2048x1080
  3. 3840x2160
  4. 7680x4320

Answer(s): C

Explanation:

Ultra HD (commonly called 4K UHD) refers to a display resolution of 3840×2160 pixels, which is four times the pixel count of Full HD (1920×1080).



A technician is troubleshooting stylus issues on identical company-provided tablets. Users can purchase their own accessories. Some users have no issues, but others report that their styluses charge intermittently and die frequently. Which of the following is the most likely cause of this issue?

  1. Certain cases are causing charging issues.
  2. The tablets need to be updated.
  3. Some of the tablets have manufacturing defects.
  4. The malfunctioning styluses need firmware updates.

Answer(s): A

Explanation:

Because the tablets and styluses are otherwise identical, intermittent charging and rapid battery drain usually point to a physical obstruction - namely, some third-party or thick cases blocking the inductive charging contacts between the tablet and stylus. Removing or replacing the case restores proper charging alignment so the stylus holds a full charge.
