Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 246

Due to a major version change, an engineer must perform a software upgrade on a Cisco Nexus Series switch.

Which two technologies should be implemented to reduce disruptions to the network during the upgrade? (Choose two.)

Answer options

• A. vPC
• B. HSRP
• C. VDC
• D. VRF
• E. VTP

Correct answer: A, B

Explanation

vPC (Virtual Port Channel) allows for redundancy and load balancing, minimizing downtime during the upgrade. HSRP (Hot Standby Router Protocol) provides high availability by ensuring that a standby router is ready to take over if the primary fails, thus reducing potential disruptions. The other options, VDC, VRF, and VTP, do not specifically address minimizing disruptions during a switch upgrade.
