Question 1

When configuring integrated ESRS access to a Dell EMC Unity XT array, which firewall ports need to be open?

Accepted Answer

ESRS uses port 443 for HTTPS and port 8443 for ESRS communication.

Question 2

A storage administrator wants to expand the current FAST Cache size from 1.2 TB to the maximum allowed size on a Dell EMC Unity XT 880. How many drives, and of what type, do they need to add?

Accepted Answer

What types of file retention are available with the Dell EMC Unity XT family arrays?

Accepted Answer

The Dell EMC Unity XT family arrays offer Enterprise and Compliance file retention options, which are designed to meet different levels of data protection and regulatory compliance requirements.

Question 10

What is an advantage for selecting Centralized ESRS over Integrated ESRS?

Accepted Answer

Centralized ESRS allows multiple systems to connect through a single gateway, meaning only the gateway needs internet connectivity, not each individual system.

Question 11

What is a consideration when expanding a dynamic pool?

Accepted Answer

When expanding a dynamic pool, the maximum number of drives in a drive partnership group is a consideration, which is 64.

Question 12

A storage administrator attempts to restart the Management Server to resolve Unisphere issues, but is unable to do so. What is a possible reason for this issue?

Accepted Answer

The SP is in Reset and Hold mode, which prevents it from being restarted.

Question 14

A company with multiple remote offices has decided to use asynchronous replication. What systems support this capability?

Accepted Answer

Dell EMC Unity XT and Dell EMC UnityVSA both support asynchronous replication, allowing data to be replicated between systems at different locations without requiring a constant connection.

Question 15

While provisioning storage on a Dell EMC Unity XT array, the Create LUN wizard becomes unresponsive. To resolve the issue, the storage administrator plans to restart the management server from the Unisphere GUI. Which account password is needed for this activity?

Accepted Answer

The Service account password is needed to restart the management server from the Unisphere GUI on a Dell EMC Unity XT array.

Question 16

A storage administrator is monitoring the pool Capacity of two identical Dell EMC Unity XT systems. Each system has every LUN replicated to the other system and all replication sessions are in sync. Both systems are used for production storage. CloudIQ is receiving updates from both systems, but shows that one of them is filling up more quickly than the other. What is a possible explanation for this behavior?

Accepted Answer

Data Reduction may not be identically enabled on LUNs on both systems, leading to different storage consumption rates.

Question 17

A storage administrator performs a monthly performance analysis of a Dell EMC Unity XT storage array using CloudIQ insight reports. Three LUNs are set with a Host IO Limits policy. The administrator discovers that the throughput IOPS on one LUN (Test_LUN) has increased by 1000 IOPS compared to the two previous months. What is a possible root cause of the spike in IOPS?

Accepted Answer

The increase in IOPS is likely due to the host IO limit of Test_LUN being edited and increased by 1000 IOPS, allowing more throughput.

Question 18

A Windows test server ran a stress test program that generated a large amount of throughput. This resulted in performance slowdowns on production hosts sharing the same VMFS datastore. What Dell EMC Unity XT feature can the storage administrator use to prevent a re-occurrence of this problem?

Accepted Answer

The answer of A Windows test server ran a stress...
