Question 2

You have completed a rolling conversion fromDNS to GNScluster resolution from the database andcluster resources end.The remaining are the configuration changes to be done from theclient side.
Which two items need to betaken into account to achieve a successful connection?

A. For each client using a SCAN, change the SCAN theclient uses so that theclient uses the SCAN in the domain delegated to GNS

B. All the nodes in the cluster need to be bounced oneafter the otherinorder for the changes to be completed as it is not possible to do it online

C. There is no need to change anything in client configuration as the combination of TAF and ONSwillautomatically take care of reaching the correct nodes

D. For each client using VIP names, change the VIP name on eachclient sothat they use the same server VIP name, but with the domain namein thedomain delegated to GNS.

Correct Answer: A,D

Question 4

Which statementaccurately describes the benefit of the policy-managed database feature with OracleRAC12cR1?

A. Itprotects against cascade failures due to load.It ensures workload isolation between pools.Less important workloads shut down transactionally

B. It protects against cascade failures due to load.It ensures workloads are not isolated between pools.Less important workloads shut downtransactionally.

C. It protects against cascade failures due to load.It ensures workload isolation between pools. Less important workloads shut down and start uniformly.

D. Itprotects against cascade failures due to network usage. It migratesworkload isolation to specific pools. Less important workloads shut down immediately.
