You are tasked with checking the status of the Exadata Database Service (ExaDB) components using...

A. dcli -g cell_group "list cell attributes name, status" combined with dcli -g dbnodes "srvctl status database -d dbname"

dcli Utility:

dcli(Distributed Command Line Interface) allows you to run commands on multiple nodes simultaneously.

cell_group: A group configuration file listing all storage cells.

dbnodes: A group configuration file listing all database nodes.

Commands Explanation:

dcli -g cell_group "list cell attributes name, status":

Retrieves the name and current status of each storage cell.

dcli -g dbnodes "srvctl status database -d dbname":

Checks the status of the database instances on the compute nodes.

Combining these commands provides a complete picture of both storage and compute components.

Why the other options are incorrect:

B. Including metriccurrent:Produces excessive output, not suitable for a quick health check.

C. Listing dbnodes only:Insufficient as it lacks storage cell status.

D. dcli -g all "list status":Invalid syntax and lacks specificity.
