Designing Cisco Network Service Architectures (ARCH, legacy) — Question 15

How does stub routing affect transit routes in EIGRP?

Answer options

• A. Transit routes are passed from a stub network to a hub network.
• B. It is designed to prevent the distribution of external routes.
• C. It prevents the hub router from advertising networks learned from the spokes.
• D. Transit routes are filtered from stub networks to the network hub.

Correct answer: C

Explanation

The correct answer is C because stub routing prevents the hub router from advertising routes learned from the spoke routers, ensuring that only specific routes are shared. Options A and D incorrectly suggest that transit routes are passed or filtered, which contradicts the purpose of stub routing. Option B, while related to route distribution, does not specifically address the interaction between stub and transit routes.
