An administrator is setting up the Cisco Unified IM and Presence on-premises high availability feature and wants the Server Recovery Manager to initiate failover after 90 seconds. However, failover is

Question

Options

• AChange peer Heartbeat Timeout to 90 seconds.
• BChange Keep Alive (Heartbeat) Interval to 90 seconds.
• CChange critical service delay to 90 seconds.
• DChange Keep Alive (Heartbeat) Timeout to 90 seconds.

• A
  4% (1)
• B
  7% (2)
• D
  89% (25)

Explanation

In Cisco IM and Presence HA, the Server Recovery Manager uses two heartbeat parameters: Keep Alive (Heartbeat) Interval (how often heartbeat packets are sent between peers) and Keep Alive (Heartbeat) Timeout (how long SRM waits without receiving a heartbeat before declaring the peer failed and initiating failover). Since failover is occurring at 60 seconds but 90 seconds is desired, the Keep Alive (Heartbeat) Timeout must be increased to 90 seconds (Answer D). Changing the interval affects frequency of checks, not the failover trigger window. Peer Heartbeat Timeout and 'critical service delay' are not the correct parameter names for this setting.
