To initiate the establishment of a TCP connection between BGP routers.

Answer

To facilitate the discovery of neighboring routers and establish peering relationships.

Question 23

Differentiate between internal and external routing protocols. Which of the following accurately describes their key distinction?

Accepted Answer

Internal routing protocols operate within a single autonomous system, while external routing protocols facilitate communication between different autonomous systems.

Answer

Internal routing protocols always choose the shortest path, while external routing protocols may consider other factors.

Answer

Internal routing protocols are inherently more secure than external routing protocols.

Answer

Internal routing protocols do not support path summarization, unlike external routing protocols.

Question 24

Explain the fundamental difference between a default route and a static route.

Accepted Answer

A default route acts as a catch-all rule, matching any destination not explicitly defined in the routing table, while a static route precisely specifies both the destination network and the next-hop IP address for reaching it.

Answer

Default routes always take precedence over static routes in routing decisions.
