HP HP Certifications HPE0-J50 Questions & Answers

• Question 21:

  An HPE StoreVirtual 3200 solution specifies 802.3ad (LACP) bonding is required for the network interfaces. What must be considered when implementing this solution?

  A. Only one of the chosen network interfaces will actively pass traffic.

  B. The network interfaces chosen may operate at the different speeds.

  C. Additional switch configuration will be necessary.

  D. The network interfaces chosen must be cabled to different switches.

  Correct Answer: C

  HPE StoreVirtual 3200 provides three options for the teaming/bonding of the network ports on each storage controller--Active-Passive, Link Aggregation Dynamic Mode (LACP), or Adaptive Load Balancing (ALB) bonding. The simplest solution, the Active-Passive bonding, utilizes only one of the available network ports per controller. The most complex solution, the LACP (802.3ad) bonding, delivers bandwidth aggregation and redundancy across both controller network ports but requires additional switch configurations such as IRF trunking. The preferred and recommended bonding mode is ALB, where the network ports may be connected to different switches, therefore, support switch failover.

• Question 26:

  A storage administrator has deployed a Windows 2012 R2 server which needs to have a virtual volume exported from an HPE StoreServ 8200.

• Question 27:

  An HPE MSA 2042 supports three different types of drives. What is the best practice when enabling storage tiering?

  A. Configure affinity per virtual volume and schedule optimization times.

  B. Create three storage pools; assign performance and standard tiers to controller A and assign archive tier to controller B.

  C. Configure affinity per storage pool, and set up virtual volume for tiering enabled.

  D. Create three storage pools, assign them to same controller, and define affinity at a Virtual Volume level.

  Correct Answer: A

• Question 28:

  A customer has an HPE 3PAR StoreServ 8000 system with three tiers of SSDs, SAS HDDs, and NL SAS. They are using Adaptive Flash Cache (AFC) and Adaptive Optimization (AO) across all three tiers. They want to implement a new virtual desktop infrastructure and want to use deduplication on the array for this workload. The integrator is in the process of implementing additional SSD drives to prepare the array for the new workload.

  What must the integrator do to implement this solution?

  A. Disable AO to enable deduplication.

  B. Disable AFC to enable deduplication.

  C. Configure a new CPG for the SSD tier.

  D. Create a new Virtual Domain.

  Correct Answer: C
