Anti-phishing training is a method of educating users on how to identify and avoid phishing attacks, which are attempts to trick users into revealing sensitive information or performing malicious actions by impersonating legitimate entities or persons. Whaling attacks are a specific type of phishing attack that target high-level executives or influential individuals within an organization. Anti-phishing training can help users recognize the signs of whaling attacks and prevent them from falling victim to them. Screened subnet, firewall, and antivirus are not items that can directly address the issue of whaling attacks.

When upgraded computers are not able to obtain an IP address, the issue often lies in the network configuration. Here's a

Option A: The switch is only providing IPv6 addresses.This is unlikely because if the switch were providing IPv6 addresses, the devices would still receive an IP address, albeit an IPv6 one. The issue described indicates no IP address is being obtained at all.

Option B: The OS must be updated to be compatible with the imaging software.This option is unrelated to obtaining an IP address. Compatibility with imaging software would not prevent the devices from getting an IP address.

Option C: The switch has port security enabled.Correct Answer. Port security on a switch restricts access based on MAC addresses. If the MAC addresses of the upgraded computers are not recognized or have not been added to the allowed list, the switch will not provide network access, resulting in the computers not obtaining an IP address.

Option D: The switch does not support multicast traffic.This is unrelated to obtaining an IP address. Multicast traffic deals with specific types of network communication and would not affect the basic DHCP IP address assignment process.

The Resource Monitor provides real-time data on CPU, memory, disk, and network usage, making it the best tool to identify performance degradation over time. It allows technicians to check which processes are consuming excessive system resources.

A . Reliability history -- Incorrect. Reliability Monitor tracks system errors and crashes, but it does not help diagnose ongoing performance issues.

B . Computer management -- Incorrect. Computer Management provides system utilities but does not offer real-time monitoring of resource usage.

D . Disk defragment -- Incorrect. Disk defragmentation improves disk access times but is unrelated to an application gradually slowing down.
