Answer: D

Scenario: A network administrator has set up two NetScalers in HA. However, when the administrator checks the HA nodes, the secondary unit shows as DOWN Details were gathered from the secondary unit and are displayed below.
IP Address: 12.44.107
Node State: NOT UP
Master State:Secondary
Fail-Safe Mod: OFF
Synchronization State: SUCCESS
HA Propagation: ENABLED
Enabled Interfaces: 1/5 1/6 1/7 1/8
Disabled Interfaces: 1/1 1/2 1/3 1/4
SSL Card status: UP
HA Monitor on Interfaces: 1/6 1/7 1/8
Interfaces on which heartbeats are not seen: 1/5 1/6
Interfaces causing partial failure: 1/6
HelloInterval (msecs): 200
Dead Interval (sees): 3
Node in Secondary state for 15 Min(s) 0 Sec(s)
ID: 1
IP Address:
Node State: UP
Master State: Primary
Fail-Safe Mode: OFF
Synchronization State: ENABLED
HA Propagation: ENABLED
Enabled Interfaces: 1/5 1/6 1/7 1/8
Disabled Interfaces: 1/1 1/2 1/3 1/4
SSL Card status: UP
HA Monitor on Interfaces: 1/7 1/8
Interfaces on which heartbeats are not seen: 1/5 1/6
