The symptoms described, such as the operating system taking longer than usual to load and hearing clicking sounds from within the workstation, are indicative of a failing hard drive. Clicking sounds, often referred to as the "click of death," signal the read/write head of the hard drive struggling to function properly. This mechanical failure leads to longer load times as the system struggles to read data from the disk. It is crucial to back up data and consider replacing the hard drive to prevent data loss.

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.

Since the on-premises email server has been decommissioned and users are experiencing issues with scan-to-email functionality, the best solution would be to configure an email relay. An email relay server can accept emails from devices like printers and forward them to the correct destination (such as a cloud-based email service). This avoids the need to bring back the old server or set up a new one.

A. Configure an email relay on an existing server: This allows the scanner to send emails through another server, ensuring the functionality is restored.

Why the other options are incorrect:

B. Configure a secure, cloud-based email relay: While a cloud-based solution could work, configuring an email relay on an existing server is a more immediate and likely solution.

C. Bring the old email server back into production: This is unnecessary and would defeat the purpose of decommissioning it.

D. Configure a new email server from scratch: Setting up a new email server would be time-consuming and not necessary in this situation.

Reinstalling RAM in different slots addresses possible issues with dual-channel configurations. If not installed correctly, the system might not recognize the full capacity. This solution is immediate and doesn’t incur extra costs, unlike replacing hardware. It reflects CompTIA A+ Core 1 exam objectives on hardware troubleshooting, specifically RAM installation and configuration​.

Self-encrypting hardware, such as self-encrypting drives (SEDs), provides an effective solution for securing data with minimal user interaction. SEDs automatically encrypt all data stored on the drive without requiring any special software or user action, ensuring that data remains protected even if the drive is removed from the device. This feature is particularly beneficial for remote users who may not consistently follow manual encryption procedures, offering a seamless and user-transparent method to secure sensitive data.

RAID 10 (also known as RAID 1+0) combines the features of RAID 1 (mirroring) and RAID 0 (striping) to provide both redundancy and performance enhancements. This configuration requires a minimum of four drives and offers fast data access through striping while ensuring data redundancy through mirroring. RAID 10 is ideal for environments where both data integrity and performance are critical, such as financial databases.

Since the user can ping 8.8.4.4 (an external IP address) but is unable to browse web pages, it indicates that the DNS (Domain Name System) settings may be incorrect or not configured. The DNS system is crucial for translating human-friendly domain names into IP addresses. If DNS settings are incorrect, the browser cannot resolve domain names, thus web pages will not load despite the network itself being reachable via IP. The other options are less likely as they would affect connectivity to external IP addresses or the availability of specific websites.

After the implementation of SSL (Secure Sockets Layer) redirection, the inability of users to access certain web-based applications or content, like a random number generator, suggests a compatibility or compliance issue with HTTPS (HyperText Transfer Protocol Secure). The first troubleshooting step should be to verify if the website in question supports HTTPS, as SSL redirection forces connections to use HTTPS for security. If the website only operates over HTTP, it won't be accessible after SSL redirection is implemented, leading to the issues reported by users.
