Dell EMC Specialist – Systems Administrator, VMAX All Flash and PowerMax — Question 9

You are configuring a DD Cloud Tier and ECS system as part of a LTR cloud backup solution. When adding the Cloud Unit in the Data Domain system you cannot connect to the ECS system.
What is preventing the configuration from being completed?

Answer options

• A. The namespace used for DD Cloud Tier is applied to a federated VDC instead of a single VDC.
• B. Two different DD Cloud Units were added as ג€Dell EMC Elastic Cloud Storage (ECS)ג€.
• C. Other namespaces reside on the same storage pool where the namespace for DD Cloud Tier is created.
• D. Ports 9020 and 9021 are closed in the firewall between the DD system and the ECS load balancer.

Correct answer: B

Explanation

The correct answer is B because adding two different DD Cloud Units as 'Dell EMC Elastic Cloud Storage (ECS)' can lead to configuration conflicts, preventing the connection. Options A and C do not directly relate to connectivity issues, and option D pertains to firewall settings rather than the specific problem of multiple units, making them less relevant in this context.
