Oracle Database Administration 2019 Certified Professional — Question 82

Which two statements are true about High Availability NFS (HANFS)? (Choose two.)

Answer options

• A. HANFS provides high availability in case of an NFS client failure.
• B. HANFS' performance depends on the characteristics of the underlying ASM disks.
• C. HANFS does not depend on NFS services provided by the underlying operating system.
• D. HANFS provides high availability in case of cluster node failure.
• E. NFS client requests are distributed by DNS in a round-robin fashion to the cluster nodes that export the NFS filesystem.

Correct answer: B, D

Explanation

The correct answers are B and D because the performance of HANFS is indeed tied to the characteristics of the ASM disks, and it provides high availability during a cluster node failure. Option A is incorrect as HANFS does not provide high availability for NFS client failures, and C is incorrect because HANFS does rely on the underlying operating system's NFS services. Option E is also incorrect since DNS is not responsible for distributing NFS client requests in this manner.
