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

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.

Which is a valid reason for using Coherence Elastic Data?

A. You want to cache more that the total amount of RAM on your systems.
B. You want to extend your cluster across a WAN.
C. Data must be persisted to disk to ensure fault tolerance.
D. You want to store data on very large heaps.

Answer: A


Which configuration file must a user edit to configure Oracle HTTP Server?

A. httpd.conf
B. obj.conf
C. workers.properties
D. magnus.conf
E. oraclehttp.conf

Answer: A

You are doing capacity planning for a Coherence application with one distributed cache (dcache), and one replicated cache (rcache). You have one index on dcache, and dcache has backup_count=1. Your requirement is that you must be able to tolerate one machine failure with no loss of data. You have three machines, each with 4 JVMs GB.
What three factors do you take into consideration in case of machine failure? (Choose three.)

A. Each cache server will be responsible for more primary and backup data from dcache.
B. The size of index data in each cache server is likely to grow.
C. The size of rcache on each node will grow.
D. Updates to rcache will result in more network traffic per machine.
E. Updates to dcache will result in more network traffic per machine.

Answer: A,B,E
