Question
Scenario: A Junior Citrix Administrator needs to create a content switching virtual server on a Citrix ADC high availability (HA) pair. The NSIP addresses are 192 168.20.10 and 192.168.20.11. The junior administrator connects to NSIP address 192.168.20.10 and saves the changes. The following day, a Senior Citrix Administrator tests the new content switching virtual server, but it is NOT working. The senior administrator connects to the HA pair and discovers that everything the junior administrator configured is NOT visible. Why has the Citrix ADC lost the newly added configurations?
Options
- AThe junior administrator made the changes and did NOT force a failover to save the
- BThe junior administrator connected to the NSIP of the secondary Citrix ADC in the HA pair.
- CThe Citrix ADC appliances have different firmware versions.
- DBoth Citrix ADCs in the HA pair restarted overnight.

Explanation
Important note: The stated correct answer of D appears to be incorrect based on Citrix ADC HA behavior. The technically accurate answer is B, and most Citrix exam resources would agree.
Why B is correct: In a Citrix ADC HA pair, configuration changes must be made on the primary node. The HA sync mechanism replicates config from primary to secondary - not the reverse. If the junior admin connected directly to the secondary node's NSIP (192.168.20.10), any changes saved there would be overwritten the next time the primary synced its config to the secondary, making those changes disappear entirely.
Why D is wrong: If both appliances restarted overnight, saved configurations would survive because save config writes to ns.conf on disk - restarts do not wipe saved configs. A restart only clears unsaved running configuration changes.
Why A is wrong: Forcing a failover is not required to propagate configuration; HA sync handles that automatically from primary to secondary.
Why C is wrong: While mismatched firmware can cause HA instability or sync issues, it does not specifically explain a complete loss of configuration made on one node.
Memory tip: Think "Primary writes, Secondary receives." Always identify which node is primary before making changes - connecting to the wrong NSIP is one of the most common real-world HA mistakes.
If this question appears on your exam with D listed as correct, flag it - the Citrix HA architecture clearly points to B.
