Check Point Certified Security Expert (CCSE) R81.20 — Question 3

Which upgrade method you should use upgrading from R80.40 to R81.20 to avoid any downtime?

Answer options

• A. Multi-Version Cluster Upgrade (MVC)
• B. Zero Downtime Upgrade (ZDU)
• C. Connectivity Upgrade (CU)
• D. Minimal Effort Upgrade (ME)

Correct answer: A

Explanation

The Multi-Version Cluster Upgrade (MVC) is designed to allow for seamless upgrades without any service interruptions, making it the ideal method in this scenario. The Zero Downtime Upgrade (ZDU) is also effective but is more suited for specific situations. Connectivity Upgrade (CU) and Minimal Effort Upgrade (ME) do not specifically focus on avoiding downtime during the upgrade process.
