1Y0-230 Exam - Question 8


Scenario: A Citrix Administrator has configured a NetScaler active-passive high availability (HA) pair. When the HA pair fails over, customers are unable to access the hosted websites. After some troubleshooting, the administrator found that the upstream router was NOT updating its ARP table.

What can the administrator configure to resolve this issue?

Show Answer
Correct Answer: B

When configuring a NetScaler active-passive high availability (HA) pair, ensuring that the upstream router updates its ARP table after a failover is crucial. This can be addressed by configuring a Virtual MAC (VMAC). By using VMAC, the MAC address used by the primary node is shared by the secondary node upon failover. This prevents the need for the upstream router to learn a new MAC address and update its ARP table, thus ensuring a seamless transition and continuous accessibility of hosted websites.
