Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 27
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. MLAG
- E. PAgP
Correct answer: A, B
Explanation
vPC (Virtual Port Channel) allows for active-active links and helps maintain network connectivity during the upgrade. HSRP (Hot Standby Router Protocol) ensures that there is a backup router ready to take over if the primary fails, which also aids in reducing downtime. The other options, while useful in certain scenarios, do not specifically focus on minimizing disruptions during a software upgrade.
