CompTIA Updated SK0-005 Exam Questions and Answers by kiaan

Replacing hardware components, such as a video card, can sometimes lead to compatibility issues, especially if the system's firmware (BIOS/UEFI) does not support the new hardware. In this scenario, the server operates, and the display functions correctly, but there are performance issues like slow response times. This suggests that while the basic functionality is intact, there may be underlying compatibility problems affecting overall system performance.

A server has multiple fans inside the chassis to cool down the components and prevent overheating. If one of the fans fails, it can cause the server to reboot and crash due to thermal issues. A failed fan can also make loud noises due to friction or vibration. The administrator should check the fans and clean them from dust and debris, or replace them if they are damaged12.

A warm site is a backup site that has some of the necessary hardware, software, and network resources to resume operations, but not all of them. A warm site requires some time and effort to become fully operational. A warm site is different from a cold site, which has minimal or no resources, and a hot site, which has all the resources and is ready to take over immediately.

Asnapshotis a point-in-time image of a system's state that can be created while the system is running, without interrupting operations. Snapshots can be used to restore the entire system to the exact state at the time of the snapshot. They are commonly used in virtualized environments and allow administrators to roll back to a previous state if needed.

Snapshot (Answer A):Captures the entire system's state and can be taken without downtime.

Archive (Option B):Refers to long-term storage, not necessarily something that supports live backups.

Open file (Option C):Refers to a method that handles open files during backup but doesn’t provide full system restoration capabilities.

Differential (Option D):Backs up only the data changed since the last full backup but still requires a full backup for complete system restoration.
