質問 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. Because near caching does not work with Elastic Data, configure a near cache and an eviction policy on the cache servers.

B. Configure Elastic Data on your clients with a near cache.

C. Configure a near cache on your client and a Flash Journal on your cache servers.

D. Configure a near cache on your client and a RAM Journal on your cache servers.

正解: C

質問 3

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. Configure a "cache-miss-scheme" on the appropriate cache.

B. This can't be achieved with Coherence.

C. 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.

D. 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.

正解: C

質問 4

A Coherence node dies and is removed from a cluster.
What two actions occur if that node was part of a distributed cache where backup_count =
1? (Choose two.)

A. Partitions are moved so that the data is balanced among remaining nodes.

B. Data is re-partitioned so that all data is accessible again.

C. Backup partitions are promoted to be primary, and new backups are created.

D. Access is blocked to all operations while the cluster is rebalanced.

正解: A,D

質問 5

An Oracle RAC Database appliance was initially deployed with two database instances.
The load on the database has now increased and another instance needs to be provisioned.
How would you add one more instance of the earlier deployed appliance?

A. Use the createAssemblyInstance operation to create a new instance of the existing assembly and deploy the new assembly instance.

B. Create and deploy a new assembly containing a single instance database appliance.

C. Use the ScaleAppliance operation to scale up the deployed appliance instances from two to three.

D. Add a new single instance database appliance into the previously created assembly and redeploy it.

正解: A
