ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 97

Which three statements about HSRP operation are true? (Choose three)

Answer options

• A. The virtual IP address and virtual MAC address are active on the HSRP Master router.
• B. The HSRP default timers are a 3 second hello interval and a 10 second dead interval.
• C. HSRP supports only clear-text authentication
• D. The HSRP virtual IP address must be on a different subnet than the routers’ interfaces on the same LAN.
• E. The HSRP virtual IP address must be the same as one of the router’s interface addresses on the LAN.
• F. HSRP supports up to 255 groups per interface, enabling an administrative form of load balancing.

Correct answer: A, B, F

Explanation

Option A is correct because the virtual IP and MAC addresses are indeed active on the Master router in HSRP. Option B is also correct as the default hello and dead intervals are specified. Option F is correct as HSRP can support multiple groups for load balancing. Options C, D, and E are incorrect because HSRP supports both clear-text and MD5 authentication, the virtual IP must be in the same subnet as the router interfaces, and it should not match the router's interface addresses.
