Which of the following statements about IP routes are correct?

Question

Options

• AIn a LAN, a route consists of the following parts: IP address and MAC address.
• BIP routes are used to guide IP packet forwarding.
• CRouting is a concept at the second layer of the OSI model.
• DAny route must contain the following information: source address, destination address, and next

• A
  5% (1)
• B
  79% (15)
• C
  11% (2)
• D
  5% (1)

Explanation

Let us analyze each option: Option A: Incorrect. A route does not include MAC addresses. It typically consists of a destination network, subnet mask, next-hop address, and outgoing interface. Option B: Correct. IP routes are essential for guiding the forwarding of IP packets from the source to the destination. Routers use routing tables to determine the best path for packet delivery. Option C: Incorrect. Routing is a concept at the network layer (Layer 3) of the OSI model, not the data link layer (Layer 2). Option D: Incorrect. A route does not require the source address. It only needs the destination network, subnet mask, and next-hop information. Thus, the correct answer is B.
