Designing Cisco Network Service Architectures (ARCH, legacy) — Question 37

How does OTV provide STP isolation?

Answer options

• A. by using STP root optimization
• B. by using BPDU filtering
• C. by dropping BPDU packets
• D. by using BPDU guard C

Correct answer:

Explanation

The correct answer is C, as OTV provides STP isolation by dropping BPDU packets, which prevents STP information from being propagated across different OTV sites. Options A and B do not specifically address the isolation aspect, while option D involves protection against misconfigurations but does not contribute to STP isolation.
