Designing Cisco Network Service Architectures (ARCH, legacy) — Question 92

A company requires redundancy for its multihomed BGP external connections. What two features can be configured on the WAN routers to automate failover for both outbound and inbound traffic? (Choose two.)

Answer options

• A. AS path prepending
• B. local preference
• C. floating static route
• D. HSRP
• E. MED
• F. weight

Correct answer: A, D

Explanation

AS path prepending helps influence the path selection for outbound traffic, while HSRP provides redundancy for IP addresses, ensuring failover for inbound traffic. The other options, such as local preference and weight, influence path selection but do not provide the same level of automated failover capabilities for redundancy.
