NEW QUESTION 2
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.

NEW QUESTION 10
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 of 8 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.

NEW QUESTION 13
An application frequently requests data (from s Coherence cache configured with a cache loader) that may not be available in the underlying data source. The cost of looking up data via the cache loader is expensive in terms of time and resources.
To reduce these costs, which configuration should be used to cache the notion that an entry is not available?

• A. Modify the application to maintain a “misses” cache to keep track of the entries that were expected to be found in the other cache, but were recently not found.
• B. Configure a “cache-miss-scheme” on the appropriate cache.
• C. Modify the cache loader to maintain a “map” of entries not found, and consult this map before attempting to load an entry from the external source.
• D. This can't be achieved with Coherence.

Answer: A

NEW QUESTION 14

NEW QUESTION 16
Your application will store data in two partitioned caches, each configured for one backup. You have calculated the total amount of data to be 10 GB for the first cache, and 3 GB for the second cache. You plan to run 10 cache servers in total.
What is the minimum recommended JVM heap size for each cache server?

• A. 512 GB
• B. 1 GB
• C. 2 GB
• D. 4 GB

Answer: C

Explanation:
When considering heap size, it is important to find the right balance. The lower bound is determined by per-JVM overhead (and also, manageability of a potentially large number of JVMs). For example, if there is a fixed overhead of 100MB for infrastructure software (for example, JMX agents, connection pools, internal JVM structures), then the use of JVMs with 256MB heap sizes results in close to 40% overhead for non-cache data. The upper bound on JVM heap size is governed by memory management overhead, specifically the maximum duration of GC pauses and the percentage of CPU allocated to GC (and other memory management tasks).
