220-1101 CompTIA Exam Lab Questions

A syslog server collects and stores log data from various network devices and systems.

A discharged CMOS battery often causes a system to lose track of time and date settings when powered off, as this battery powers the real-time clock. The BIOS settings, including time and date, revert when this battery fails. Option A (time server misconfiguration) would impact multiple devices. BIOS updates (Option B) and CPU performance (Option D) are unrelated to timekeeping issues, as outlined in CompTIA A+ Core 1 (220-1101) exam objectives under hardware troubleshooting.

A network tap (Test Access Point) is a device used for monitoring network traffic. It allows the technician to passively observe the traffic between two network nodes in real-time without introducing latency or affecting the network's performance. By using a network tap, the technician can analyze the data packets flowing through the network to identify if packet loss is occurring, which could be contributing to the slow network traffic in the branch office.

References: Network taps are widely recognized in the field of network troubleshooting and monitoring for their ability to provide a mirror of the traffic that can be analyzed for issues such as packet loss.

The IPv4 address (192.168.10.5) and the gateway address (192.168.1.1) are on different subnets. With a netmask of 255.255.255.0, the network part of the IPv4 address is 192.168.10.x, while the network part of the gateway address is 192.168.1.x. For the workstation to correctly route traffic to the gateway, both must be on the same subnet. The correct gateway address should be within the same subnet as the IPv4 address, such as 192.168.10.1.
