NEW QUESTION 8
You are using Coherence to store state data that gets read frequently and updated only occasionally. Only 100 or so clients are logged in at any time, and state data is retrieved at login. You are running out of physical memory on the cache server tier, but CPU and network utilization is low. You have 100 GB Solid-State Drives on every system, including clients. You would also like to provide faster access to state data for logged-in users.
Which configuration should you use for your system?

• A. Configure Elastic Data on your clients with a near cache.
• B. Configure a near cache on your client and a RAM Journal on your cache servers.
• C. Configure a near cache on your client and a Flash Journal on your cache servers.
• D. Because near caching does not work with Elastic Data, configure a near cache and an eviction policy on the cache servers.

Answer: C

NEW QUESTION 9
How would you create an SLA based on the “JVM Runtime Up” metric for a specific WLS server?

• A. Deploy JVM Diagnostics and set a threshold on the JVMD agent up time.
• B. Create a Service target that uses the WLS Domain as its system, and the JVM Runtime as itsperformance metri
• C. Configure SLA by using that metric.
• D. Define a threshold on the metric on the All Metrics page, and define a rule to create an Event for that inciden
• E. Define an SLA on the count of Incidents.
• F. You cannot create an SLA on JVM-related metrics.

NEW QUESTION 21
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: CD

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.
