E. Primary site volumes paths are standby read/write
Correct Answer: AD
Question 3:
A customer has an HPE Nimble Storage array. They plan to add a second HPE Nimble Storage array to their existing group. What is the expected write behavior to a volume once the new array is added to the same pool as the existing array?
A. Data will be written to the new array until it is the same percent full as the original array

C. Data will continue to write to the first array until there is 40% free space available, and then alternate writes between the two arrays
D. Data will be stripped and automatically re-balanced across the two arrays
Correct Answer: A
Question 4:
A customer has three 4-node HPE 3PAR arrays. Two of the arrays are deployed at a primary site, and the third array is deployed at a disaster recovery site. Both arrays at the primary site are replicated to the single array at the disaster
recovery site.
All replication is asynchronous periodic. All arrays are utilizing 4 RCIP links for replication.
The customer needs to add a third array at the primary site. They would like to use the existing array at the disaster recovery site as a replication target for this additional array.
What must the architect consider to meet this customer requirement?
A. A single pair of RCIP ports on one array can have a Remote Copy relationship with up to two other arrays
B. Remote Copy fan-in ratios of greater than 2:1 are only supported with RCIP when using 10 Gb Ethernet links
C. Arrays involved in a Remote Copy relationship must have the same number of node pairs
D. Asynchronous streaming replication must be used for Remote Copy fan-in ratios greater than 2:1
Correct Answer: A
Question 5:
A customer needs to setup specific replication bandwidth requirements to limit the bandwidth between HPE Nimble Storage replication partners, which is different than the bandwidth requirements to another Replication Partner. Which Bandwidth parameter should the customer use?
A. Array-to-array Limit
B. Per-partner limit
C. Partner Maximum limit
D. Overall limit policy
Correct Answer: B
Question 6:
You have chosen to utilize HPE 3PAR synchronous replication in order to meet the customer stated requirement of RPO=0. What is a key consideration you need to explain to the customer?
A. Host write latencies will decrease
B. Host write latencies will increase
C. Host writes can be committed to either primary or backup storage before host acknowledgment
D. RC sync can only be deployed over FC links
Correct Answer: B

Question 7:
You are proposing a replication solution to a customer. A competitor offers a solution based on storage virtualization appliances. What should you stress about an HPE 3PAR replication solution in regard to the competitor\’s proposal?
A. It will add on-the-fly encryption and compression to data being replicated outside the customer\’s DC
B. It means less overhead for management and monitoring
C. It offers best-in-class backup and restore capabilities
D. It offers superior virtualization of 3rd party storage arrays
Correct Answer: B
Question 8:
Which advantage is provided by HPE 3PAR Remote Copy across all replication modes?
A. support of all Remote Copy topologies
B. automatic recovery of array failure independent of Remote copy topology
C. Remote Copy support up to 100ms latency over all transport layers
D. all Remote Copy topologies yield identical RPO and RTO
Correct Answer: A

Question 9:
A customer has started to load their HPE 3PAR 8450 with data, but are not sure what data reduction they are achieving. They ask you to run analysis and estimate the deduplication ratio of data currently on a virtual volume (VV). Which CLI command should you use to understand data reduction ratios?
A. showvv
B. tunevv
C. convertvv
D. checkvv
Correct Answer: D

Question 10:
A customer needs to new storage solution, including replication. The replication solution does not need to provide an RTO or RPO of zero.
The customer suffers from severe VM sprawl and has experienced unidentified storage service-level degradations.
What should you point out during your presentation of the solution?
A. Hardware-assisted parity generation and deduplication mitigate the changing performance requirements
B. VMs are always individually visible to the array with automatic enablement of VVOL technology
C. InfoSight and VM details would help in identifying misbehaving VMs putting a high load on the array
D. When a storage system is being overloaded, the replication software will automatically move the workload
Correct Answer: B
Question 11:
A customer has HPE B-series switches and is not interested in Extended Fabric licenses for edge switches. They have sites over 10km apart. Which SAN extension technology should you recommend?
A. FC over DWDM
B. FC over CWDM
C. FCoE
D. FCIP
Correct Answer: D
