QUESTION 37
You are in the process of designing a VMAX3 solution. One of the applications requires performance equivalent to Flash disks. Which Service Level Objective should be recommended?
A. Diamond
B. Platinum
C. Optimized
D. Gold
Answer: A
QUESTION 38
You are discussing the design of a VMAX3 solution with a customer. The customer wants to know the difference between a FAST managed Storage Group and a non-FAST managed Storage Group. When is a Storage Group (SG) considered FAST managed?
A. Service Level Objective is explicitly set on the SG.
B. SG is part of a Masking View.
C. Host I/O limits are explicitly set on the SG.
D. SG is associated with a FAST policy.
Answer: A
QUESTION 39
You are discussing the design of a VMAX3 solution with a customer. The customer wants information about the performance data collected for FAST. At which levels are FAST performance metrics collected on the array?
A. Disk Group, Storage Group, thin device sub-LUN.
B. Disk, Data Pool, Storage Resource Pool.
C. Disk Group,Data Pool, thin device sub-LUN.
D. Data Pool, Storage Resource Pool, Storage Group.
Answer: A
QUESTION 40
You are in a meeting with a customer discussing virtual provisioning on VMAX3 arrays. The customer wants information on Storage Resource Pool allocation management. What is the basis for the allocation of new extents to a device?
A. Data Pool Ranking and SLO.
B. Data Pool RAID types and SRP capacity.
C. Data Pool Ranking and SRP capacity.
D. Data Pool RAID types and default SLO.
Answer: A
QUESTION 41
You are discussing VMAX3 FAST algorithms with a customer. The customer wants to know more about the relationship between the Service Level Objectives and the algorithms. Which algorithm is the basis for the Optimized Service Level Objective?
A. Disk resource protection
B. SLO capacity compliance
C. SLO response time compliance
D. SRP capacity compliance
Answer: A
QUESTION 42
A customer has an existing Masking View on a VMAX3 for a large server cluster. The parent Storage Group in this Masking View has several child Storage Groups with different SLOs. The customer has determined that they need to add additional capacity to the cluster. When the storage administrator attempts to add devices directly to the parent Storage Group, the administrator receives an error and the operation fails. What is a potential cause of the error?
A. Adding devices and Storage Groups to the same parent Storage Group is not permitted.
B. A Storage Group must not be in a Masking View to be modified.
C. Cluster is exceeding the assigned Host I/O limit.
D. Devices are not yet associated with an SLO policy.
Answer: A
QUESTION 43
A storage administrator uses Unisphere for VMAX to provision new Storage Groups on a VMAX3 array. Which Workload Type is recommended for small block I/O workloads?
A. OLTP
B. None
C. DSS
D. Optimized
Answer: A
QUESTION 44
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 an expected average response time.
B. Workload Type can be assigned to Platinum-associated Storage Groups and emulates Flash, 15K RPM, and 7.2K RPM drive performance.
C. Platinum SLO emulates Flash and 15K RPM drive performance and has a configurable average response time.
D. No Workload Type can be assigned to Platinum-associated Storage Groups and it places the most active data on higher performing storage.
Answer: A
QUESTION 45
A VMAX3 parent Storage Group (SG) contains two child SGs: SG1 and SG2. What is a valid Host I/O bandwidth limit setting for this configuration?
A. Parent SG – 400.
SG1 – 500, SG2 – 200.
B. Parent SG – 400.
SG1 – 500, SG2 – NOLIMIT.
C. Parent SG – 500.
SG1 – 500, SG2 – 400.
D. Parent SG – 500.
SG1 – NOLIMIT, SG2 – 1000.
Answer: C
QUESTION 46
A VMAX3 parent Storage Group (SG) contains two child SGs: SG1 and SG2. What is a valid Host I/O limit setting for this configuration?
A. Parent SG – 400,000.
SG1 – 500,000, SG2 – 300,000.
B. Parent SG – 400,000.
SG1 – 500,000, SG2 – NOLIMIT.
C. Parent SG – 500,000.
SG1 – 400,000, SG2 – NOLIMIT.
D. Parent SG – 500,000.
SG1 – NOLIMIT, SG2 – 1,000,000.
Answer: C
QUESTION 47
You are in a meeting with a customer to discuss storage provisioning on VMAX3 arrays. What is a consideration for Autoprovisioning Groups on VMAX3 arrays?
A. An initiator may only belong to one Initiator Group.
B. A device cannot belong to more than one Storage Group.
C. A port may only belong to one Port Group.
D. Maximum number of levels of cascading permitted in a Storage Group is 64.
Answer: A
QUESTION 48
A VMAX3 customer has an existing Masking View for a large database environment. The parent Storage Group in this Masking View has three child Storage Groups with different SLOs. The customer has been experiencing some database performance issues and wants to set the SLO to Platinum for all the devices. When the storage administrator attempts to set the SLO on the parent Storage Group, the administrator receives an error and the operation fails. What is the cause of the error?
A. SLOs may not be set on the parent Storage Groups.
B. A child Storage Group already has the Platinum SLO applied.
C. There is insufficient capacity in the SRP.
D. Suitability Check has failed.
