B.

tangosol.coherence.site

C.

tangosol.coherence.management

D.

Question 2

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?

Options:

A.

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

Question 3

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?

Options:

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.
