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

  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

Show answer
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)

Which answer describes the possible locations from which the operating system would be loaded at system initialization?

cisco-ccna

  1. NVRAM, TFTP Server, ROM

  2. NVRAM, TFTP Server, RAM

  3. TFTP Server, FTP Server, ROM

  4. Flash memory, TFTP Server, ROM

  5. NVRAM, Flash memory

Show answer
Correct Option: D

AI Explanation

To answer this question, we need to understand the possible locations from which the operating system can be loaded at system initialization.

Option A) NVRAM, TFTP Server, ROM - This option is incorrect because it does not include Flash memory as a possible location.

Option B) NVRAM, TFTP Server, RAM - This option is incorrect because it does not include Flash memory as a possible location.

Option C) TFTP Server, FTP Server, ROM - This option is incorrect because it does not include Flash memory or NVRAM as possible locations.

Option D) Flash memory, TFTP Server, ROM - This option is correct. The operating system can be loaded from Flash memory, which is a non-volatile memory that retains data even when power is removed. It can also be loaded from a TFTP (Trivial File Transfer Protocol) Server, which allows for remote loading of files. ROM (Read-Only Memory) is also a possible location.

Option E) NVRAM, Flash memory - This option is incorrect because it does not include ROM or TFTP Server as possible locations.

The correct answer is D. This option includes all the possible locations from which the operating system can be loaded at system initialization: Flash memory, TFTP Server, and ROM.
