Designing Cisco Network Service Architectures (ARCH, legacy) — Question 39

An engineer is working on a design solution for a large hub-and-spoke EIGRP network. Which feature helps to make this design more stable while also reducing resource utilization?

Answer options

• A. QoS
• B. network summarization
• C. stub routing
• D. route filtering C

Correct answer:

Explanation

The correct answer is C. Stub routing simplifies the routing table by preventing unnecessary routes from being advertised to certain routers, thereby reducing resource use and increasing stability. Options A (QoS), B (network summarization), and D (route filtering) do not specifically target the stability and resource utilization in the context of a hub-and-spoke design as effectively as stub routing does.
