CompTIA A+ Certification Exam: Core 2 Sample Questions (Q231-Q236):

NEW QUESTION # 231
An application's performance is degrading over time. The application is slowing, but it never gives an error and does not crash. Which of the following tools should a technician use to start troubleshooting?

A. Computer management
B. Disk
C. Resource monitor
D. Reliability history

Answer: C

Explanation:
Resource Monitor provides real-time insights into CPU, memory, disk, and network usage by process. By observing which resources steadily increase or become bottlenecks over time, a technician can pinpoint leaks (e.g., memory), I/O contention, or other performance issues driving the slowdown.

NEW QUESTION # 232
A technician is setting up a surveillance system for a customer. The customer wants access to the system's web interface on the LAN via the system's IP address. Which of the following should the technician use to prevent external log-in attempts from the internet?

A. Subnetting
B. Content filtering
C. Static IP
D. Port mapping

Answer: D

Explanation:
By using port mapping (NAT) rules on the router, you can choose to forward the surveillance system's HTTP/HTTPS ports only on the LAN interface and leave them closed on the WAN side.
This ensures users on the local subnet can access the camera interface via its IP address, while external login attempts from the internet are blocked.

NEW QUESTION # 233
A technician notices that the weekly backup is taking too long to complete. The daily backups are incremental. Which of the following would most likely resolve the issue?

A. Running synthetic full weekly backups
B. Changing the backup window
C. Increasing the backup storage
D. Performing incremental weekly backups

Answer: A

Explanation:
A synthetic full backup combines the last full backup with subsequent incremental backups to create a new full backup without re-reading data from the source system. This method significantly reduces the backup window and network impact. It is especially useful when traditional full backups are too time-consuming.
A). Changing the backup window only shifts timing, not duration.
B). Incremental weekly backups would lack a proper full recovery point and aren ' t ideal alone.
C). Storage space isn ' t the bottleneck in backup speed-it's read/write operations and network load.
Reference:
CompTIA A+ 220-1102 Objective 4.2: Summarize backup and recovery concepts.
Study Guide Section: Backup types - full, incremental, differential, and synthetic backups

NEW QUESTION # 234
A popular game frequently freezes and crashes on a mobile phone. The user updates the OS, but the issue persists. The device is one year old and has plenty of free storage space. Which of the following is the most appropriate first step to troubleshoot this issue?

A. Changing the device's date and time settings
B. Reinstalling the application
C. Factory resetting the device
D. Disabling background applications

Answer: B

Explanation:
The correct answer is A. Reinstalling the application, because the issue appears to be application-specific rather than system-wide. The problem only affects one game, the operating system is fully updated, and there are no storage constraints. These indicators strongly suggest corrupted application data or a faulty app installation.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, when a single application crashes repeatedly, the first recommended troubleshooting step is to remove and reinstall the app. This clears corrupted files, resets application settings, and ensures the latest compatible version is installed.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide emphasizes that factory resets should only be used as a last resort, as they are disruptive and erase user data. Disabling background applications may help performance issues but does not typically resolve persistent crashes tied to one specific app.
The Mike Meyers / Mark Soper Lab Manual further clarifies that date and time misconfiguration usually affects authentication or certificate validation, not game stability.
Because the symptoms are isolated to a single application and basic system factors have already been ruled out, reinstalling the application is the most appropriate first troubleshooting step, making A the correct answer.

NEW QUESTION # 235
A user is trying to install new software. The application downloads successfully, but when the user attempts to install it, the user receives a prompt for credentials. Which of the following would the technician most likely do to resolve this issue?

A. Use a different web browser to download the application
B. Contact the software vendor for support
C. Change the User Account Control (UAC) settings
D. Restart the user's computer

Answer: C

Explanation:
The correct answer is C. Change the User Account Control (UAC) settings, because the credential prompt during installation indicates that the system is requesting administrative privileges. In Windows environments, UAC is designed to prevent unauthorized system changes by prompting for administrator approval when elevated permissions are required.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, UAC acts as a security boundary between standard user activities and system-level changes such as software installation. If a user does not have sufficient privileges, the system will request administrator credentials before proceeding.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that technicians can temporarily adjust UAC settings or provide proper elevation to allow legitimate installations. This is especially common in corporate environments where users operate with standard accounts.
The Mike Meyers / Mark Soper Lab Manual reinforces that restarting the computer or using a different browser does not change permission requirements. Contacting the software vendor is unnecessary when the issue is clearly related to local security controls.
Because the installation is blocked by privilege restrictions enforced by UAC, adjusting User Account Control settings or providing proper elevation is the correct and most efficient resolution, making C the correct answer.
