Designing Cisco Data Center Infrastructure (DCID) — Question 30

An engineer is designing a Multichassis EtherChannel topology in which two switches must appear as a single device to a third downstream switch? Which two technologies meet this requirement? (Choose two.)

Answer options

• A. HSRP
• B. VSS
• C. vPC
• D. 802.1q
• E. FEX

Correct answer: B, C

Explanation

The correct answers are VSS and vPC, as both provide a way for multiple switches to operate as a single logical switch, allowing for redundancy and load balancing. HSRP is primarily used for high availability and does not offer the same functionality in this context, while 802.1q is a VLAN tagging protocol and FEX is for fabric extensions, neither of which create a single device appearance.
