Correct Answer: Top-left laptop: Swollen battery → A replacement is required
Top-middle laptop: Cannot locate boot partition → Enter the BIOS and configure changes
Top-right laptop: Incorrect contrast settings → Adjust the display settings
Phone (left): Keysetting → Disable the keys
Projector (left): Fuzzy image → Adjust the display angle settings
Projector (right): Wrong input selected → Switch the display input
Phone (right): Burn in → Adjust the refresh rate settings
Bottom-left monitor: Overheating → Disable overclocking in the CPU
Bottom-right monitor: Run ll → Upgrade the hard drive
Explanation: Match each visible symptom with the closest issue and standard troubleshooting action.
Question 12
An organization upgrades all of its desktop machines to Windows 11. The organization must ensure that all machines are protected from malicious software on startup. Which of the following advanced options should the organization enable?
A. Trusted Platform Module
B. Hardware security module
C. Secure Boot
D. BIOS password
Show Answer
Correct Answer: C
Explanation: Secure Boot helps protect systems from malicious software during startup by ensuring that only trusted, signed bootloaders and operating system components are loaded. TPM enhances key protection and attestation but does not by itself prevent boot-time malware. An HSM is for centralized cryptographic key management, and a BIOS password only restricts firmware access.
Question 13
Which of the following is the best to use to stream real-time video from a network camera?
A. UDP
B. TCP
C. FTP
D. RDP
Show Answer
Correct Answer: A
Explanation: UDP is generally the best choice for streaming real-time video from a network camera because it prioritizes low latency over guaranteed delivery. Occasional packet loss is typically preferable to the delays caused by retransmissions in TCP. FTP is for file transfer, and RDP is for remote desktop access.
Question 14
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: Virtual Desktop Infrastructure (VDI) hosts desktop environments centrally and delivers them remotely to users, allowing access to full desktop resources without issuing physical workstations. RMM is for remote monitoring and management, SaaS delivers software applications, and containers package applications rather than providing user desktop environments.
Question 15
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 isolated systems where potentially unsafe or unauthorized code can be executed without affecting the host or production environment. Hybrid clouds, load balancers, and application gateways are infrastructure components not primarily intended for safely executing untrusted code.
Question 16
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: A flickering display is commonly caused by an incorrect or unsupported monitor refresh rate. Screen resolution affects image size and sharpness, pixel density is a hardware characteristic, and LCD type does not directly address flickering in this context.
Question 17
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: Active Directory domain joins depend on DNS to locate domain controllers. If the client is using manually configured DNS servers that do not point to the AD-integrated DNS service, the domain cannot be located. The other options are not inherently problematic: DHCP can be enabled, NetBIOS being enabled does not prevent a domain join, and there is no evidence that the subnet mask is incorrect.
Question 18
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 keeps local folders and files consistent across devices by propagating updates made on one device to the others. Network shares provide shared access but do not inherently synchronize local folders. Availability refers to service accessibility, and metered utilization relates to usage-based resource consumption.
Question 19
A user's smartphone frequently disconnects from Wi-Fi networks, particularly in crowded areas like airports and coffee shops. The user also notices that their device shows a lower Wi-Fi signal strength compared to other devices in the same location. Which of the following is likely contributing to the smartphone's Wi-Fi connectivity issues?
A. The smartphone's antenna may be malfunctioning.
B. The smartphone may have an outdated Wi-Fi standard.
C. The smartphone may be experiencing interference from nearby devices.
D. The smartphone's power settings may be affecting performance.
Show Answer
Correct Answer: A
Explanation: Consistently lower reported Wi-Fi signal strength than other devices at the same location suggests a hardware reception problem, such as a faulty or damaged antenna. Crowded environments can increase contention and interference, but they would typically affect nearby devices similarly rather than causing one device to consistently show weaker signal.
Question 20
A customer is using port 110 for email. However, the customer wants to upgrade to a more secure connection that automatically synchronizes with the server. Which of the following should the customer use?
A. IMAP
B. HTTPS
C. SMTP
D. SFTP
Show Answer
Correct Answer: A
Explanation: Port 110 is POP3, which is less suitable for multi-device synchronization. IMAP is the secure upgrade in terms of email access behavior because it keeps messages on the server and synchronizes mailboxes across devices. HTTPS is for web traffic, SMTP is for sending email, and SFTP is for file transfers.
