220-1101 Practice Test

Explanation: Based on the information provided in the scenario, the most likely cause of the issue is that the user’s internet connection is down (option A). This would explain why the user is unable to access any of the organization’s servers or network items and why web pages are not functioning. However, since the user can still access local file folders and other local machines, it suggests that their local network is still functioning.
The user can access local file folders and other local machines but none of the organization's servers or network items, indicating that the issue is with the user's internet connection, not with the user's domain account, switch, or IP address.
When a user receives a notification indicating that there is limited or no connectivity, it means that their device is unable to establish a connection to the network. In this scenario, the user can access local file folders and other local machines but is unable to access any of the organization’s servers or network items and web pages are not functioning. This suggests that the issue is with the user’s internet connection.
An internet connection allows a device to communicate with other devices and servers outside of its local network. If the internet connection is down or not functioning properly, the device will be unable to access any resources outside of its local network. This would explain why the user in this scenario can still access local resources but is unable to access any of the organization’s servers or network items.

Explanation: To fix a Cat 5 cable issue where the cable fails when it is moved around, the technician would need to use an RJ45 connector (option E) and a crimper (option F). The technician can use the crimper to attach a new RJ45 connector to the end of the cable, which should resolve the issue.

An RJ45 connector (option E) is a type of connector commonly used for Ethernet networking. It is an 8-position, 8-contact (8P8C) modular plug and jack that is used to terminate Cat 5 and other types of twisted pair cables. A crimper (option F) is a tool used to attach connectors to the ends of cables. In this case, the technician would use the crimper to attach a new RJ45 connector to the end of the Cat 5 cable.

When a cable fails when it is moved around, it often indicates that there is a problem with the connector at the end of the cable. By attaching a new RJ45 connector using a crimper, the technician can ensure that the cable has a secure and reliable connection.

Explanation: After resolving the immediate issue (reactivating server credentials), verifying system functionality ensures the solution works as intended and the user can now access the shared drive. This step is a part of the CompTIA troubleshooting methodology:
✑ Identify the problem.
✑ Establish a theory of probable cause.
✑ Test the theory to determine the cause.
✑ Establish a plan of action.
✑ Implement the solution.
✑ Verify full system functionality.
✑ Document findings, actions, and outcomes.
✑ Why Not B (Document the findings): Documentation comes after verifying the system works.
✑ Why Not A (Escalate the issue): Escalation is unnecessary since the problem was resolved.
✑ Why Not C (Perform backups): Performing backups is unrelated to verifying credential functionality.
CompTIA 220-1101 : Practice Test CompTIA A+ Exam Reference: Core 2 (220-1102), Section 3.1, troubleshooting methodology.

Explanation: After the issue has been identified and the backup of the system has been made, the next step is to establish a theory of probable cause. This involves researching the issue to determine the root cause of the problem. This can involve researching internally (e.g. referring to the system logs) or externally (e.g. searching online). Once the probable cause has been identified, the technician can then move on to the next step of designing a plan of action to resolve the issue and implementing the solution.
