220-1102 Exam Dumps - CompTIA A+ Questions and Answers

To confirm whether a network printer has connectivity issues, the technician should use:

ping: This command checks the connectivity to the printer by sending packets and measuring the response time. It helps determine if the printer is reachable on the network.

netstat: Provides statistics and current network connections but does not directly confirm connectivity to a specific device.

net: Used for network resources management but not specifically for checking connectivity.

nslookup: Used for querying DNS to obtain domain name or IP address mapping, not for checking connectivity.

Comprehensive and Detailed In-Depth Explanation:

Joining a Windows client to a domain requires Enterprise administrative permissions because only domain administrators or authorized users can add computers to an Active Directory (AD) domain.

A. Local access – Incorrect. A user does not need to be physically near the computer; the action can be performed remotely.

B. Internet connection – Incorrect. A domain join occurs over a local network, not the internet.

D. Computer MAC address – Incorrect. MAC addresses are used for network identification but are not required to join a domain.

Steps to Join a Domain:

Open Settings > System > About > Domain or Workgroup Settings

Click Change settings > Change

Enter the domain name and provide admin credentials

Restart the computer

The issue could have been avoided if the developer had used Sandbox testing (Option D), which allows new software to be tested in a controlled environment before implementation. This process ensures that the software does not negatively impact system functionality, like stopping access to critical resources such as file servers.

End-user acceptance (Option A) ensures that users approve the software, but it wouldn't prevent the issue.

Staff delegation (Option B) relates to who is responsible but doesn't address testing.

Appropriate scoping (Option C) helps in defining the extent of changes but does not replace testing.

Restarting a smartphone is a basic troubleshooting step that often resolves temporary software glitches or minor errors that might be preventing the screen rotation from working correctly. It's a quick and easy step to try before moving on to more complex solutions.

Here's why the other options are not the best first step:

A. Remove the screen protector: While a thick or improperly installed screen protector could potentially interfere with the sensors responsible for screen rotation, it's less likely to be the cause.

B. Update the smartphone’s software: While software updates can fix bugs and improve functionality, they are not always necessary for resolving a screen rotation issue.

D. Replace the smartphone: Replacing the smartphone is a drastic measure and should only be considered if other troubleshooting steps fail.

Troubleshooting Steps:

Restart the smartphone: This often clears temporary software issues.

Check for software updates: If a restart doesn't work, updating the operating system or any relevant apps might resolve the issue.

Calibrate the accelerometer: Some smartphones have a calibration tool for the accelerometer, the sensor that detects orientation. Check the device settings for this option.

Check for hardware issues: If the problem persists, there might be a hardware issue with the accelerometer or other components. In this case, contacting the manufacturer or a repair center might be necessary.
