Which of the following items should be included in complete route information?

Question

Options

• Adestination Nettwerk
• Bnext top address
• Cdestinations subnet and mask
• Dsource Nettwerk address

• A
  83% (45)
• D
  17% (9)

Explanation

Complete route information requires three key components: the destination network (A), the next hop address (B), and the destination's subnet and mask (C). Together, these tell a router where a packet is going, how to reach the next point along the path, and how to identify which addresses belong to that destination network. Without any one of these three, a router cannot make a complete, accurate forwarding decision.

Why D is wrong: The source network address plays no role in routing table entries. Routing is fundamentally destination-based - routers forward packets based on where they're going, not where they came from. Including the source address is a characteristic of firewall rules or access control lists, not routing tables.

Memory tip: Think of a routing entry as a delivery instruction - you need the street/neighborhood (destination network), the zip code boundary (subnet mask), and the next delivery depot (next hop). You never need to know who sent the package to deliver it forward.

Note: The question contains apparent typos - "Nettwerk" likely means "Network," and "next top address" likely means "next hop address." Recognize these on exams and map them to standard networking terms.
