Introducing Cisco Data Center Networking (DCICN) — Question 10

What are three modular Layer 2 processes in Cisco Nexus Operating System? (Choose three.)

Answer options

• A. UDLD
• B. PIM
• C. HSRP
• D. STP
• E. Cisco Discovery Protocol
• F. OSPF

Correct answer: A, D, E

Explanation

The correct answers are UDLD, STP, and Cisco Discovery Protocol, as they pertain specifically to Layer 2 processes in the Cisco Nexus Operating System. PIM, HSRP, and OSPF are not Layer 2 processes; PIM functions at Layer 3 for multicast, HSRP is a redundancy protocol, and OSPF is a routing protocol also operating at Layer 3.
