QUESTION 1
Which two mechanisms are explicitly monitored to determine death of a cluster member? (Choose two.)

A. garbage collection
B. stuck threads
C. heartbeats
D. TCP socket connections

Answer: C,D

Explanation:
Explanation
Death detection works by creating a ring of TCP connections between all cluster members.
TCP communication is sent on the same port that is used for cluster UDP communication.
Each cluster member issues a unicast heartbeat, and the most senior cluster member issues the cluster heartbeat,
which is a broadcast message. Each cluster member uses the TCP connection to detectthe death of another node
within the heartbeat interval. Death detection is enabled by default and is configured within the <tcp-ring-listener> element.
