Looking at the network configurations and outputs from both PCs and servers, here are the possible issues and solutions:

1. PC 1

Issue: The IP address for PC1 is 192.168.1.1, which conflicts with Server 1 (which also uses 192.168.1.1).

Solution: Change the IP address on PC1 to a unique one within the range, like 192.168.1.3.

2. PC 2

Issue: PC 2 is configured with 192.168.1.2, which conflicts with Server 2 that has the same IP address.

Solution: Update the IP address on PC 2 to something unique, like 192.168.1.4.

3. Server 1

Issue: The IP address for Server 1 is 192.168.1.1, which conflicts with PC1.

Solution: Since Server 1 and PC1 are using the same IP address, change one of them. For Server 1, you could change the IP address to 192.168.1.5.

4. Server 2

Issue: Server 2 is using the IP address 192.168.1.2, which conflicts with PC2.

Solution: Update Server 2 to use a different IP address, such as 192.168.1.6.

General Remediation:

The primary problem here is overlapping IP addresses, leading to connectivity issues. Each device on the network must have a unique IP address. After making these changes, ensure that all devices can communicate properly by testing the connection between devices and verifying they can access shared resources.

To change adomain passwordfrom a remote location, the system must communicate with thedomain controller. Since the user is working from home, they need toconnect to the corporate VPNto establish that secure connection. Without it, the password change cannot be authenticated.

Option A:Restarting will not resolve the lack of connection to the domain controller.

Option C:Resetting the password in AD could help, but doesn’t let the user reset it themselves.

Option D:The user may already be on Wi-Fi; the issue is with connecting to thecorporate network, not local.

Wireless coverage issues at the physical edges of a building are typically caused by weak RF signal strength. The CompTIA A+ study material says the best solution is to add additional wireless access points (APs) or implement a mesh system to extend coverage and eliminate dead zones.

Enabling 5GHz often worsens the issue because 5GHz has shorter range. Wi-Fi 6 NIC upgrades improve performance but do not increase signal reach. Flushing DNS does not affect wireless coverage.

Installing more APs ensures stronger coverage, better signal-to-noise ratio, and stable connectivity aligning with CompTIA’s wireless troubleshooting best practices.

Elasticity in cloud computing refers to the ability of a system to automatically allocate and release resources (such as CPU, RAM, or virtual machines) as workload demands change. This feature is key to ensuring that resources are used efficiently without manual intervention.

Older motherboards use 20-pin connectors, while newer power supplies use 24-pin connectors. An adapter resolves the compatibility issue cost-effectively.

Why Not A (Adjust the input voltage): Input voltage adjustment is unrelated to connector compatibility.

Why Not B (Install a modular power supply): While modular supplies are versatile, this doesn’t address the connector issue directly.

Why Not C (Rebuild the failed power supply): Rebuilding is costly and complex compared to using an adapter.

CompTIA A+ teaches that S.M.A.R.T. warnings indicate imminent drive failure. Even if the RAID controller reports the array as “healthy,” a S.M.A.R.T. alert means the drive should be replaced immediately.

RAID 5 provides redundancy for one drive failure, but technicians should replace the degrading drive before it fails fully, ensuring the rebuild happens proactively.

Running chkdsk affects file systems, not drive health. Disabling write caching is unrelated. Rebuilding the array should only occur after replacing the faulty drive.

Replacing the drive prevents a catastrophic dual-drive failure scenario, which RAID 5 cannot survive.

This approach aligns with CompTIA troubleshooting guidelines for RAID maintenance and S.M.A.R.T. diagnostics.

When a device shows asnot connectedeven though it previously paired, the most effective action is tore-pair the devices. This resets the Bluetooth connection, clears any corruption in pairing profiles, and re-establishes communication.

Option A:Entering a PIN is only relevant during initial pairing and may not be prompted again.

Option B:Turning off Wi-Fi doesn’t typically affect Bluetooth; they operate on similar frequencies but don’t conflict this way in normal use.

Option D:If Bluetooth were disabled, the device wouldn’t appear at all, not just show as “not connected.”
