A company is evaluating the deployment of SRDF/Star on VMAX3 arrays. One of the concerns is that the SRDF daemon represents a single point of failure.
How could this concern be addressed?

• A.RDF daemon process runs on the VMAX3 array.If the workload site RDF daemon fails, the RDF daemon from one of the other sites will take over.
• B.Run RDF daemons on multiple management stations at the workload site.RDF daemons will cooperate with each other.
• C.Run an RDF daemon on one management station at each of the three sites.If the workload site RDF daemon fails, one of the RDF daemons from the other two sites will take over.
• D.RDF daemon process runs on the embedded Tools Virtual Machines and has built-in high availability.

To determine Service Level Objective compliance on a VMAX3, where is the I/O response time measured?

• A.Frontend Directors
• B.Host Bus Adapters
• C.SAN Switches
• D.Backend Directors

Which role does the Unisphere for VMAX initial setup user have after the creation of a new user with the
"Admin" role?

• A.Admin
• B.Nine
• C.Auditor
• D.SecurityAdmin

In an SRDF/Metro environment, what is a requirement for an Array Witness?

• A.Two RDF groups on the witness array; one to the source and one to the target
• B.Witness RDF between the source and the target
• C.One RDF group on the witness array to both the source and the target
• D.Witness RDF group on the witness array containing the source and the target SRDF/Metro devices

While analyzing performance of a VMAX3 array, the following details are observed?
* High host response time
* Low FE response time
* High host CPU utilization
What should be investigated further?

• A.Disk delays
• B.I/O queuing on the host
• C.SAN connectivity
• D.I/O queuing on the frontend
