Ace Your 220-1102 A+ Exam

In this scenario, the user cannot access a separate subnet, and all other checks (credentials, network stability, and permissions) have been verified. The next logical step is to check if the user's IP address is being blocked by a firewall.

Option A: Consult with the firewall team to see if the user's IP address is blockedFirewalls can block specific IP addresses, preventing access to certain network segments. Given the problem's nature and the steps already taken, this is the most logical next step to ensure the user's IP is not inadvertently blocked.

Option B: Delete the user’s credentials and create new onesThis step is unnecessary since the credentials have already been verified as correct.

Option C: Run a virus scan on the user's workstationWhile important for overall security, a virus scan is unlikely to resolve an issue specific to accessing a subnet if the problem does not affect other users.

Option D: Update the network drivers on the user’s workstationIf the network connection is stable and the issue is isolated to accessing a specific subnet, network drivers are unlikely to be the cause.

Detailed Explanation with Core 2 References:If multiple unsuccessful attempts led to the account being locked, the technician should unlock the account. Core 2 covers user account management practices, including unlocking accounts and managing failed login attempts (Core 2 Objective 2.5)​.

Drilling is a method of physically damaging the hard drive by drilling holes through it, which renders the drive inoperable. However, it is not a secure method for ensuring data cannot be recovered. Methods such as wiping or degaussing are more secure.

Time drift occurs when the internal clock of a computer is not properly synchronized, often leading to discrepancies like being an hour behind. In this case, the workstation is the only device affected, indicating that it's likely a local issue. Time drift can happen if the system clock isn't syncing properly with an NTP (Network Time Protocol) server or if automatic daylight savings adjustments aren't enabled. It's less likely to be a CMOS battery issue since the technician has already verified the correct date and the system clock isn’t completely reset (which is what happens when the CMOS battery fails).
