The digitizer is the component responsible for detecting touch input on a screen. If touch is not registering and there's no physical damage, the digitizer may be faulty.

A Syslog server gathers and stores log messages and event data sent over the network from various hosts and devices, centralizing system and application logs for monitoring and analysis.

SMB (Server Message Block)is a protocol used to access files and printers over a network, including across shared network folders. It enables the user to access and print files stored remotely on a shared directory.

The workstation's IP configuration (192.168.1.27/24 with gateway 192.168.1.1) shows that it has a correct IP address, correct subnet mask, and expected default gateway for a typical small office network. Because the IP is in the correct private range and not an APIPA address (169.254.x.x), this also confirms that DHCP is functioning properly. Therefore, option D (DHCP) cannot be the cause.
The user then pings the default gateway at 192.168.1.1, which should be the router--the device providing routing between local devices and outside networks. The repeated "Request timed out" responses indicate the workstation cannot reach the router at all. This type of failure points directly to a router outage, a powered-off router, a failed router interface, or a physical disconnection of the router from the switch.
If DNS (C) were the issue, the user would still be able to ping the IP address of the gateway because DNS is not required for IP-to-IP connectivity. A web server (A) has no relation to local gateway communication and does not affect workstation access.
Since the workstation has a valid IP but cannot reach its default gateway, the failure point is the router.

The degraded status on Server 2 indicates a RAID-5 issue, typically due to a failed or failing drive. In RAID-5 configurations, when one drive fails, the system can still operate but with reduced performance as parity data is used to rebuild missing data on-the-fly.
Recommended Replacement Drive:
- To minimize performance degradation, the replacement drive should be:
- SAS HDD with the same specifications (64KB stripe size, no read-ahead, and write-back policy).
- Matching the configuration exactly ensures seamless integration and optimizes recovery speed in the RAID-5 array.
In RAID-5, degraded performance is expected when one drive fails, as parity data needs to rebuild missing information during each read/write process. Replacing the failed drive restores the RAID array to optimal status, reducing the load on existing drives and returning the system to normal read/write performance. The write-back policy and disabled disk cache settings are designed to reduce latency and increase efficiency, essential for handling real-time applications.
