Answers

Answers

C.

Answers
C.
The switch has port security enabled.
D.
The switch does not support multicast traffic.
Answers
D.
The switch does not support multicast traffic.
Suggested answer: C

Explanation:

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

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.
