NEW QUESTION 11
Your customer is a financial services company that uses a large compute grid (not Coherence) to do risk calculations. Objects representing risk scenarios are cached in Coherence. When these objects are updated, they are sent to the compute grid to recalculate risk via a continuous query cache. Assume that there are 100 compute servers in one data center and 100 GB of cached data. The customer is not worried about potential cluster instability, given their network design.
Which solution supports the customer’s requirements? Keep in mind licensing costs and features by edition.
- A. Coherence Standard Editio
- B. Nothing special is needed and Standard Edition is the low- cost option.
- C. Coherence Enterprise Edition, with the compute grid clients being storage-disabled cluster members.
- D. Coherence Grid Edition, with the compute grid clients being storage-disabled Coherence cluster members.
- E. Coherence Enterprise Edition, with the compute grid running against a set of Coherence*Extend proxies and continuous query cache on Coherence*Extend clients.
Answer: A
NEW QUESTION 12
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).

NEW QUESTION 13
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.
Answer: C
NEW QUESTION 14

NEW QUESTION 15
Which are two key factors in deciding when to configure OTD for SDP support?
- A. number of connections that OTD needs to manage
- B. size of the payload that will be load balanced
- C. whether Oracle Traffic Director is deployed with InfiniBand fabric
- D. request rate
Answer: C
NEW QUESTION 16
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
Answer: D
NEW QUESTION 17
What is the difference between Entry Processors and Aggregators?
- A. Entry Processors require a key or a set of keys, whereas Aggregators require filters.
- B. Entry Processors can skip the network by executing against near caches directly, whereas Aggregators must execute on storage members.
- C. Entry Processors are better suited to Map-Reduce operations than Aggregators.
- D. Aggregators are optimized for read-only access, whereas Entry Processors can modify cacheentries.
Answer: D
NEW QUESTION 18
