Question 4

You are designing an SRDF/S solution. Network bandwidth can be purchased in increments of single OC1 (52 Mb/s) links. Data compression is not in use. The workload profile is as follows:
Total I/Os per second = 30,000 Read block size = 4 KB Write block size = 4 KB Writes = 30%
How many OC1 links will provide sufficient bandwidth?

A. 6 B. 2 C. 1 D. 4

Question 5

The Reserved Capacity for a Storage Resource Pool (SRP) on a VMAX3 has been set to 15%. A TimeFinder SnapVX snapshot has been created for a Storage Group containing 10 devices. An application is actively performing read and write I/Os to these devices. Allocation for the SRP reaches 85%.
What will happen to the snapshot?

A. Snapshot will fail B. Snapshot will persist but new snapshot deltas cannot be created C. Snapshot deltas will be allocated from the Reserved Capacity D. Snapshot will terminate

Question 6

Two RDF groups from two VMAX3 arrays have been added to a RDF Consistency Group. SRDF/A Multi-Session Consistency (MSC) has been enabled for the Consistency Group. The RDF daemon has been started on a single host that has access to both the VMAX3 arrays.
What will happen ifthis host becomes unavailable?

A. RDF links will be suspended immediately B. Cycle switching will stop C. SRDF mode will change to Adaptive Copy Disk D. SRDF pair state will become partitioned

Question 8

How does the VMAX3 Platinum Service Level Objective (SLO) differ from the Optimized Service Level Objective?

A. Platinum SLO emulates Flash and 15K RPM drive performance and has a configurable average response time. B. No Workload Type can be assigned to Platinum-associated Storage Groups and it places the most active data on higher performing storage. C. Workload Type can be assigned to Platinum-associated Storage Groups and emulates Flash, 15K RPM, and 7.2K RPM drive performance. D. Platinum SLO emulates Flash and 15K RPM drive performance and has an expected average response time.
