Check Point Certified Security Expert (CCSE) R81 — Question 31

Which upgrade method you should use upgrading from R80.40 to R81.10 to avoid any downtime?

Answer options

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

Correct answer: D

Explanation

The Multi-Version Cluster Upgrade (MVC) method allows for an upgrade without downtime by enabling different cluster members to run different versions simultaneously. The other methods either do not guarantee zero downtime or are not suitable for this type of upgrade, making MVC the best choice for avoiding service interruption.
