As a frame travels through a routed network the Mac address will always:

  1. the source address will change and the destination address will change

  2. change to reflect the current source and destination

  3. remain the same

  4. the source address will remain the same but the destination address will change

  5. none of the above


Correct Option: B
Explanation:

To solve this question, the user needs to know about MAC addresses and how they work in a routed network.

MAC addresses are unique identifiers assigned to network interfaces by the manufacturer. Each MAC address is assigned to a specific device, and it is used to identify that device on a network.

In a routed network, packets are sent from one network to another through intermediate devices such as routers. As a packet travels through the network, the MAC address of the source and destination will change depending on the device it is passing through.

Now let's go through each option and explain why it is right or wrong:

A. The source address will change and the destination address will change: This option is incorrect because the source and destination MAC addresses will not always change. They may change as the packet passes through different devices in the network, but they may also remain the same in certain cases.

B. Change to reflect the current source and destination: This option is partially correct. The MAC address of the packet will change as it passes through different devices in the network. However, it is not changing to reflect the current source and destination, but rather to identify the device the packet is currently passing through.

C. Remain the same: This option is incorrect. While it is possible for the MAC address to remain the same in certain cases, it is not always the case.

D. The source address will remain the same but the destination address will change: This option is also partially correct. The source MAC address will not change, but the destination MAC address will change as the packet passes through different devices in the network.

E. None of the above: This option is incorrect because options B and D are partially correct.

Therefore, the correct answer is:

The Answer is: B or D (both are partially correct)
