Designing Cisco Network Service Architectures (ARCH, legacy) — Question 91

Summary address blocks can be used to support which network application?

Answer options

• A. QoS
• B. IPsec tunneling
• C. Cisco TrustSec
• D. NAT
• E. DiffServ

Correct answer: D

Explanation

The correct answer is D, NAT, because summary address blocks help in simplifying the translation of multiple IP addresses, which is essential for NAT functionality. The other options, while related to network management and security, do not specifically rely on summary address blocks to operate effectively.
