Consider the following code:
If the initial stock amount was 15, and 5 different clients (in different JVMs) attempted to execute the same code simultaneously, what would be the resulting level of stock?
A. 20, because Coherence does implicit locking
B. 15, because a concurrency control exception will be thrown
C. 16, because of the lack of concurrency control
D. undefined, because of the lack of concurrency control
Assume that network latency between two data centers is 5 milliseconds with minimal packet loss.
Identify two problems with running one Coherence cluster that spans these two data centers (Choose two.)
A. Outage in the WAN link can cause split brain.
B. Access and writes to data takes longer to complete.
C. Total loss of power in one data center can lead to split brain.
D. Network latency will lead to cluster instability.
Which change cannot be made in an assembly at deployment time?
A. setting the appliance's memory and CPU requirements
B. changing the listening port of the product
C. not deploying an appliance by setting its target count to zero
D. not deploying an appliance by removing it from the assembly
In which three scenarios would you use JRockit Mission Control? (Choose three.)
A. finding hot methods
B. static mode analysis
C. tracking latencies
D. heap analysis
E. debugging with breakpoints
What information is needed in the process of creating a patch template for WLS Domain?
A. one or more patches to apply
B. the domain target
C. stage directory (if not already staged)
D. WLS Domain Administrator credentials, and Host credentials
E. Patch Plan
Identify four components of the Oracle Cloud Application Foundation. (Choose four.)
A. WebLogic Server
B. Database
C. Virtual Assembly Builder
D. Exalogic Elastic Cloud Software
E. Tuxedo
F. Coherence
What could cause an AddTargetUser operation to fall with a 401 or a 403 error?
A. Virtual Assembly Builder Deployer application is down.
B. The user whose credentials were used to connect to Virtual Assembly Deployer has not been granted the Cloud Admin role.
C. A connection between Virtual Assembly Builder Deployer and oracle VM Manager resource pool has not been configured.
D. The Oracle VM Manager Admin user, whose credentials were used in the createTarget operation, has not been granted the Application Admin role.
Consider an application using a Coherence partitioned cache to store HTTP session data. There is a load balancer that performs client based affinity (or "sticky load balancing"), meaning that requests that come from a particular user will be routed to the same application server every time. Most user requests will read from the session, thus making near caching topology a good fit.
Which near cache configuration matches the requirements for this application?
A. AUTO
B. NONE
C. ALL
D. PRESENT
A customer is witnessing a lot of contention while accessing and updating a cached item.
Which feature alleviates the connection by shortening the time that the object is locked?
A. Near Cache
B. Entry Processors
C. Transaction Framework D. off-heap storage
What three components are not part of EM and require separate installations? (Choose two.)
A. BTM Engine
B. RUEI Engine
C. JVM Diagnostics Engine
D. Application Discovery and Performance Management Engine
E. Ops Center
