Oracle Database Administration 2019 Certified Professional — Question 83

Which two statements are true about node listeners in a Grid Infrastructure Cluster using ASM? (Choose two.)

Answer options

• A. They listen only for database instances on the same node.
• B. They listen on behalf of any ASM instance and all database instances on the same node.
• C. They listen only for the ASM instance on the same node.
• D. There can be only one node listener per node.
• E. They run from the Grid Infrastructure home by default.

Correct answer: B, E

Explanation

Option B is correct because node listeners manage connections for all database instances and any ASM instance on the same node. Option E is also correct as node listeners run from the Grid Infrastructure home by default. The other options are incorrect because they either limit the scope of the listeners or misrepresent the number of listeners allowed per node.
