• Question 56:

  An administrator is monitoring the Nutanix v5.15-based AOS cluster performance logs and notices that a SQL server VM is greatly exceeding its intended maximum IOPS. The administrator has confirmed that a QoS policy was previously created for the group of VMs this server is a member of.

  What are two reasons that this VM would exceed its maximum configured IOPS from the QoS Policy? (Choose two.)

  A. The VM is missing the required snapshot needed to implement the QoS Policy.

  C. The SQL Server VM has volume groups attached.

  D. It was cloned from another SQL Server VM that was a member of the QoS Policy.

  Correct Answer: BC

• Question 57:

  An administrator needs to make sure an RF2 cluster can survive a complete rack failure without negatively effecting workload performance. The current cluster configuration consists of the following:

  30 nodes: distributed 10 nodes per rack across three 42U rack

  Each nodes is configured with 40TB usable storage all flash (Cluster Total 1.2 PB Usable)

  Current cluster utilization is 900TB storage

  Which configuration changes should be made to make sure that the cluster meets the requirements?

  A. Expanse the cluster by adding 3 additional nodes per rack, 9 nodes total.

  B. Expanse the cluster by adding 2 additional nodes per rack, 6 nodes total.

  C. Expanse the cluster by adding 9 nodes to a new 42U rack

  D. Expanse the cluster by adding 8 nodes to a new 42U rack

  Correct Answer: A

• Question 58:

  An administrator is deploying a three-tier application on a Nutanix Enterprise Cloud consisting of web, application, and database VMs. Traffic between the servers must be limited to specific services/ports.

  There is an application layer firewall VM deployed on one host in the cluster.

  In which way should the administrator meet this requirement?

  A. Create a network for each type of VM, and use policy-based routing to control the traffic flow

  B. Configure a security policy and service chain redirecting the server traffic through the firewall

  C. Separate the web application and database VMs on to dedicated VLANs

  D. Categorize the VMs in Prism Central and utilize Flow to set a security policy

  Correct Answer: D

• Question 59:

  A guest VM is reported to have poor storage performance. It has an I/O profile of 80% read. 20% write, and the HDDs form more than 50% of the read source. What should an administrator do to resolve this issue?

  A. Increase SSD capacity

  B. Increase the OPLOG

  C. Increase the write cache

  D. Use HDDs with higher RPM

  Correct Answer: A

• Question 60:

  An administrator responsible for a VDI environment needs to investigate reports of slow logins. The administrator finds that increasing the number of vCPUs from 2 to 4 will reduce the login times. Production workloads are consuming 75% of the host CPU on the cluster. The administrator increases the vCPU count on all of the VDI VMs.

  What are two impacts on the cluster? (Choose two.)

  A. Increase CPU utilization %

  B. Increase CPU ready %

  C. Increase memory utilization %

  D. Increasing CPU counts will decrease memory utilization

  Correct Answer: AB
