EMC Proven Professional – VMAX Specialist — Question 2

You are responsible for installing a four-node RPA cluster. All RPAs are powered on. Both the FC and IP networks are connected, zoned, and routed properly.
The RPAs are loaded with the latest image and IP addresses are set. However, Deployment Manager cannot discover RPAs.
What is a possible cause?

Answer options

• A. Port 22 not open between host running Deployment Manager and RPAs
• B. Deployment Manager host and RPAs on different subnets
• C. DHCP not used to set IP addresses for RPAs
• D. RPAs not installed separately using Deployment Manager

Correct answer: A

Explanation

The correct answer is A because Deployment Manager requires SSH access to the RPAs, which typically uses port 22. If this port is not open, Deployment Manager will not be able to communicate with the RPAs. Options B, C, and D are less likely causes, as the scenario specifies proper network configuration and IP address setup.
