Important CompTIA 220-1202 Exam Questions

Answer: C

Explanation:

A repeated failure to open Task Manager---a core Windows troubleshooting utility---strongly suggests the system is compromised and critical tools are being interfered with. In malware-response methodology, Quentin Docter emphasizes that the first step is to ''identify and verify the malware symptoms'' before proceeding to containment and remediation. If Task Manager cannot be launched at all, that behavior itself is a highly suspicious symptom consistent with malicious activity attempting to prevent the administrator from viewing or stopping processes.

Docter also explains that when systems are compromised by a virus or other malware, the threat agent may embed persistent access methods, and in some cases the only way to be sure it's fully removed is to reinstall the OS---highlighting how deeply malware can integrate and disrupt normal tools.

The other options do not plausibly block Task Manager: a developer application may increase CPU/RAM usage but typically won't prevent Task Manager from opening; Windows Update set to manual affects patching behavior; and moving the pagefile can affect performance but not usually stop Task Manager from launching.

Answer: D

Explanation:

Persistent pop-ups urging antivirus updates are likelyscareware or adware. The correct approach is toverify existing antivirus settings, run a trusted security scan, and avoid interacting with unknown pop-ups.

FromQuentin Docter -- CompTIA A+ Complete Study Guide:

''Users should verify antivirus status using trusted tools before responding to alerts. Fake updates are common vectors for malware.''

Answer: C

Explanation:

When DHCP isn't enabled, static IPs must be assigned manually, so the engineering team provides the IP details.

From Travis Everett -- All-in-One Exam Guide:

''If DHCP is unavailable, technicians need the static IP configuration to connect devices to the network.'' .

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.

Answer: B

Explanation:

To display a file's contents in Linux, the standard command is cat. Quentin Docter states: ''Sometime you just need to view the contents of a file. To view the contents of a file, use the cat command,'' and shows an example cat /etc/hosts displaying the file output. He also lists essential Linux commands and explicitly defines cat as: ''Displays the contents of a file.''

The other options do not meet the requirement: chmod changes file permissions, ls lists directory contents (or file names), and sudo runs a command with elevated privileges---none directly display a file's contents by themselves. A+ also expects you to know that cat can do more than display; it can concatenate files and redirect output, but for this question the key function is simply viewing a file.

Therefore, the correct command is cat (B).
