Question #1
What does Flow Control functionality provide?
  1. A
    It manages congestion by pausing Ethernet traffic.
  2. B
    It allows use of frame sizes up to 9000 bytes.
  3. C
    It resolves switch backplane or port oversubscription.
  4. D
    It removes the requirement to use Spanning Tree Protocol (STP).

Correct Answer:
A

Question #2
You are planning an HPE StoreVirtual architecture based on a customers physical site configuration. The customer has three physical sites and wants to span the cluster between two of them. All sites should be peers.
What should be done to meet the requirements?
  1. A
    Create a logical third site to provide a Failover Manager.
  2. B
    Configure a Failover Manager in the third physical site.
  3. C
    Configure the cluster to span both sites, and configure one site as the primary site.
  4. D
    Configure a Failover Manager in each physical site.

Correct Answer:
C

Question #3
Which requirements must be considered when designing and sizing an HPE 3PAR StoreServ environment for periodic asynchronous replication? (Select two.)
  1. A
    Use a CPG with nearline drives for Remote Copy snapshots.
  2. B
    Size only the source array to account for the IOPS resulting from snapshots created by Remote Copy.
  3. C
    Size only the target array to account for the IOPS resulting from snapshots created by Remote Copy.
  4. D
    Use a CPG with SAS drives for Remote Copy snapshots.
  5. E
    Size both arrays to account for the IOPS resulting from snapshots created by Remote Copy.

Correct Answer:
AB

Question #4
Your customer is concerned about downtime during storage system upgrades. Which method or technology addresses this concern when using an HPE 3PAR
StoreServ solution?
  1. A
    Persistent Cache
  2. B
    Persistent Ports
  3. C
    Persistent RAID
  4. D
    Persistent Peers

Correct Answer:
B

Question #5
You are talking to a prospective customer at a medium-to-large enterprise firm about an upcoming storage refresh project they have for their legacy architecture storage platforms. The customer mentions that as they grew the size and types of workloads on their present storage arrays, they became slower in terms of IOPS and throughput. In a few cases, they had to purchase additional arrays to off-load some of the workload. They noticed the same impact to performance when they enabled array-based replication.
Which HPE 3PAR StoreServ architecture feature would solve these issues?
  1. A
    The HPE 3PAR StoreServ storage array is an ideal high availability platform that runs its OS in a single instance.
  2. B
    The shared links between the controller node and each of the other nodes operates at 4 GB/s full duplex to adequately support the clustering of controller nodes and movement of data between nodes.
  3. C
    The HPE 3PAR ASIC offloads IO workload performed by microprocessors in legacy storage array platforms.
  4. D
    The HPE StoreServ storage array uses a high-speed, full-mesh active interconnect to join multiple controller nodes together to form a cache-coherent cluster

Correct Answer:
C
