View Answer

Answer: B

Explanation:

The Sticky Decision Function (SDF) is required to prevent failovers in an Active-Active cluster. The SDF ensures that the same cluster member handles all connections that belong to a certain session. If the SDF is not enabled, different cluster members may handle different connections of the same session, which may cause a failover or a drop12.
