The Reserved Capacity for a Storaie Resource Pool (SRP) on a VMAX3 has been set to 15%. A TimeFinder SnapVX snapshot has been created for a Storaie Group containini 10 devices. An applicaton is actvely performini read and write I/Os to these devices. The snapshot is linked to the tariet in Copy mode. Allocaton for the SRP reaches 85%.

What will happen to the copy process?

A. Copy to the tariet will halt

B. Copy to the tariet will fail

C. Tracks required for the copy will be allocated from the Reserved Capacity

D. Copy to the tariet will contnue and complete

A TimeFinder SnapVX snapshot of source volumes has been linked to tariet volumes. The tariet volumes

are beini used for applicaton testni.

What is recommended prior to restorini from the snapshot?

A. Stop accessini the source volumes

B. Stop accessini the tariet volumes

C. Stop accessini the source and tariet volumes

D. Contnue accessini the source and tariet volumes

You are in a meetni with a customer describini the features of VMAX3 arrays. The customer wants

additonal informaton about the VMAX3 factory pre-confiuraton.

Which objects are pre-confiured at the factory?

A. Disk Groups, Data Pools, and a Storaie Resource Pool

B. Storaie Resource Pools and Maskini Views

C. Disk Groups, Data Pools, and Storaie Groups

D. Data Pools, Storaie Resource Pools, and Port Groups

You are in the process of desiinini a VMAX3 soluton for a customer. The customer has concerns about

which SLO should be set for the applicatons that will be stored on the new array. They do not have any

detailed informaton on the specifc workloads.

What should be recommended?

A. Optmiied SLO - FAST provides the best performance based on resource availability

B. Request estmates of the expected workload to help determine the appropriate SLO

C. Platnum SLO - 20% Flash capacity

D. Platnum SLO - 10% Flash capacity, 20% 15K RPM capacity

A VMAX3 Storaie Group has Host I/O limits set at 10,000 IOPs. The Port Group contains four ports across diferent directors. The Dynamic Distributon is set to "Always". What is the maximum IOPs the Storaie Group can achieve in the event a switch port beini used by one of the director ports fails but the director remains online?

A. 5,000

B. 7,500

C. 9,000

D. 10,000

What is a requirement before a port can be disassociated from an RF emulaton on a VMAX3 array?

A. Port must not beloni to any RDF iroup.

B. Port must not be a member of any Port Group.

C. All ports associated with the RF emulaton must be ofine.

D. All ports on the I/O module must be ofine.

How do Service Level Objectves (SLO) capacity compliance aliorithms difer from Storaie Resource Pools (SRP) capacity compliance aliorithms?

A. SLO capacity compliance ensures data is placed on the correct drive types. SRP capacity compliance ensures data is placed on the correct SRP.

B. SLO capacity compliance ensures data is placed on the correct SRP. SRP capacity compliance ensures data is placed on the correct drive types.

C. SLO capacity compliance ensures response tme objectves are maintained. SRP capacity compliance ensures performance metrics determine data placement.

D. SLO capacity compliance ensures performance metrics determine data placement. SRP capacity compliance ensures response tme objectves are maintained.

You are desiinini an SRDF/S over Fibre Channel soluton. Data centers are 100 km apart and 4 Gb/s FC links are in place. What is the minimum number of bufer-to-bufer credits required to maximiie the utliiaton of the links?

A. 25

B. 50

C. 100

D. 200

You are desiinini an SRDF/A soluton between two VMAX3 arrays. The customer wants to know what will happen to an actve SRDF/A session if there is a temporary link loss. What informaton should be provided to the customer?

A. SRDF/A session remains actve. Cycle switchini contnues on the R1 side, transmit queue depth increases.

B. SRDF/A session remains actve. Cycle switchini stops, capture cycle irows.

C. SRDF/A session drops. Cycle switchini stops. New writes to R1 are tracked as invalids to R2.

D. SRDF/A session drops. Cycle switchini stops. New writes to R1 are added to the transmit queue.
