Meanwhile, periodic PAPI keepalives will fail between the MC and the previously active MM before they connect to the newly promoted MM.

VRRP keepalives are periodically transmitted between
the MM primary and standby. Should the primary MM fail, the standby MM will
cease to receive these keepalives. Thus, the standby MM detects the primary
MM as unavailable. The standby MM takes over as the active MM.
Meanwhile, periodic PAPI keepalives will fail between the MC and the
previously active MM before they connect to the newly promoted MM.

You need to setup an IPsec tunnel between the two MMs in order to synchronize the configuration and databases.
VRRP keepalives are periodically transmitted between the MM primary and standby.
periodic PAPI keepalives will fail between the MC a nd the previously active MM before they connect to the newly promoted MM.
I bet A.
SNMP (B) is a strange answer.
VRRP (C) is used for switchover in case of MM L2 redundancy, but the question is how MC discovers MM failure. There is no VRRP between MC and MM.
IPSec (D) is used to dicover failure between MMs in case of L3 redundancy, but again the question is about how MC detects…
Correct Answer: A, PAPI. pague study guide 29
correct answer is D
VRRP keepalives are for MM failover
PAPI keepalives are for MC failover
Answer is C
Correct answer: PAPI
Correct PAPI
