Question#1

A customer must protect file storage resources through asynchronous replication to other Dell Unity XT systems in different locations.
What is the maximum number of remote systems that can be configured?

A. 4
B. 24
C. 16
D. 8

Question#2

Which describes the Dell Unity XT MetroSync replication topology?

A. A source block resource replicating synchronously from Site A to Site B and replicating synchronously from Site A to Site C
B. A source file resource replicating synchronously from Site A to Site B and replicating asynchronously from Site A to Site C
C. A source file resource replicating synchronously from Site A to Site B and replicating synchronously from Site A to SiteC
D. A source block resource replicating synchronously from Site A to Site B and replicating asynchronously from Site A to Site C

Explanation:
Dell Unity XT MetroSync replication topology is a multi-site replication solution that allows you to replicate data synchronously between two or more Unity XT systems. In this topology, a source file resource is replicated synchronously from Site A to Site B, and also replicated synchronously from Site A to Site
C. This means that data is written to the primary site and immediately replicated to the secondary site, ensuring that both sites have an exact copy of the data at all times. This type of topology is useful in cases where data loss is not acceptable and a zero RPO is needed. This topology ensures that the data is fully protected and that the environment is highly available, as in case of a primary site failure, the secondary site can take over.

Question#3

When designing a Metro Volume, what configuration must be implemented to avoid unnecessary storage compute resource usage?

A. Use MRU for PSP
B. Use storage containers
C. Use DRS affinity rules
D. Place witness at a third site

Question#4

Which front-end protocol card in Dell Unity XT 380 offloads processing to save CPU cycles for other operations?

A. 4 port Fibre Channel module
B. CNA for iSCSI
C. 4 port iSCSI module
D. CNA for Fibre Channel

Question#5

What initiates an automatic NAS server failover to the peer SP?

A. Network link failure
B. Resource balancing algorithm
C. Assisted internal migration
D. SP hardware fault

Explanation:
An SP hardware fault initiates an automatic NAS server failover to the peer SP in Dell Unity systems. This ensures that the NAS services remain available in case of hardware failure in one of the Storage Processors (SPs). The failover process is automatic and transparent to the hosts accessing the data, and it helps to maintain the high availability of the NAS services.
