Nutanix Nutanix Certified Professional (NCP) NCP-MCI-6.5 Questions & Answers

• Question 1:

  Refer to exhibit:

  

  Why has an anomaly been triggered?

  A. Controller reached 2500 IOPS.

  B. Observed IOPS exceed normal values.

  C. Normal Controller behavior has increased.

  D. Observed values do not match predicted values.

  Correct Answer: D

  Explanation: Nutanix anomaly detection is a feature that monitors seasonal trends for time-series data (e.g. CPU usage, memory usage, latency, etc.) and establishes a "band" of expected values based on historical data12. Only values that

  hit outside the "band" will trigger an event / alert1.

  Nutanix leverages a method for determining the bands called `Generalized Extreme Studentized Deviate Test'. A simple way to think about this is similar to a confidence interval where the values are between the lower and upper limits

  established by the algorithm.

  Another web source3 shows an example of how anomaly detection works in Nutanix Prism Central. In the video, you can see that when the observed value of a metric deviates significantly from the predicted value based on historical data, an

  anomaly event is triggered and displayed on a chart.

  Therefore, by comparing the observed values with the predicted values based on historical data, Nutanix anomaly detection can identify abnormal behavior and alert you accordingly.

• Question 2:

  An administrator is commissioning a Nutanix Enterprise Cloud. Once the user VMs have been deployed and are running, the administrator finds that VMs on the same host are able to communicate, but are unable to communicate between hosts.

  What must be changed to enable full inter-VM communications?

  A. Change the spanning-tree port type on the switch.

  B. Change the network the VMs are connected to

  C. Update the switch to specifically allow VLAN 15

  D. The VMs need to have static IP addresses.

  Correct Answer: C

• Question 3:

  When installing Nutanix Guest Tools (NGT) on an ESXi-hosted VM, which port should be enabled on the VM to allow communication with the NGT-Controller VM service?

  A. 2000

  B. 2074

  C. 8080

  D. 9943

  Correct Answer: B

• Question 4:

  An administrator wants to ensure that data in a container is stored in the most space efficient manner as quickly as possible after being written,

  Which space efficiency too meets this requirement?

  A. Inline Compression

  B. Thin Provisioning

  C. Cache Deduplication

  D. Erasure Coding

  Correct Answer: A

  Explanation: inline compression is a technique that compresses all incoming write I/O operations over 4 KB inline in the persistent write buffer (oplog)23. This approach enables you to use oplog capacity more efficiently and helps drive sustained performance2. From AOS 5.18 onward, inline compression (compression delay=0) is enabled by default for all new containers24. https://portal.nutanix.com/page/documents/solutions/details?targetId=TN-2032-Data- Efficiency:TN-2032-Data-Efficiency

• Question 5:

  An administrator was reviewing various AOS logs when a it was noticed that the time of the logs were off by several hours.

  Which initial step was missed during the post process cluster configuration?

  A. Setting the cluster time zone via PC GUI

  B. Setting the cluster time zone via CVM NCLI

  C. Setting the cluster time zone via PE GUI

  D. Setting the cluster time zone via CVM ACLI

  Correct Answer: B

• Question 6:

  An administrator wants to reduce the largest amount of alert emails received from Prism Central.

  Which two settings should the administrator customize to meet this requirement? (Choose two)

  A. Skip empty digest email

  B. Every Single Alert

  C. Dally Digest

  D. Email Recipients

  Correct Answer: CD

  Explanation: According to the Nutanix Support and Insights website1, you can configure alert emails through Prism Central by enabling or disabling customer email notification for each alert. You can also modify or create custom alert policies for different entities and clusters23.

• Question 7:

  A configuration is single domain, single forest, and does not use SSL.

  Which port number should be used to configure LDAP?

  A. 389

  B. 3269

  C. 636

  D. 3268

  Correct Answer: A

• Question 8:

  An administrator is reviewing performance of a core banking system that routinely has 20,000 concurrent users. During, business hours, the CPU on the applications servers runs at close to 100%. The administrator needs to determine if there is a performance issue specific to the app servers, the database servers, or all servers on the cluster.

  

  Which metrics should the administrator review in Prism Analysis Graphs?

  A. Cluster IO, Network, Database and App Server CPU

  B. Cluster CPU and Memory Only

  C. Cluster IO, CPU, Memory and Database and App Server CPU

  D. Cluster IO, CPU, Memory, Network, App Server CPU

  Correct Answer: D

• Question 9:

  A customer has a newly-deployed AHV cluster with nodes that have 2.x 10 GBE and 2.x interface. The customer wants to use all available network interfaces to provide connectivity to the VMs.

  Which option should the administrator use to achieve this while remaining consistent with Nutanix recommendations?

  A. Create separate VLANs that map 10GbE and 1GbE interfaces.

  B. Createbond1 on virbr0 and add the 1GbE interfaces to it for VM use.

  C. Create a second bond on br0 on each host and assign the 1 GbE interfaces to it.

  D. Create a second bridge on each host and assign the 1GbE interfaces to it.

  Correct Answer: D

• Question 10:

  An administrator manages an AHV cluster that is dedicated to a dev/test environment. The administrator receiving complaints from users that they are unable to create new VMs on the cluster.

  After the reviewing the cluster, the administrator finds that the memory resources are almost fully utilized, with many VMs over-provisioned on memory.

  What option is the most efficient resolution to enable additional VMs to be created?

  A. Enable Memory Overcommit on the over-provisioned VMs.

  B. Enable Memory HA on the over-provisioned VMs.

  C. Upgrade the nodes with additional memory DlMMs.

  D. Disable HA Reservation on the cluster.

  Correct Answer: A

  Explanation: Enable Memory Overcommit on the over-provisioned VMs is the most efficient resolution to enable additional VMs to be created. Memory overcommit allows VMs to use more memory than physically available on a host by compressing and swapping memory pages to storage1. This can improve memory utilization and increase VM density on a cluster1. However, memory overcommit is not supported when HA is configured to use reserved hosts, so you may need to disable HA reservation on the cluster before enabling memory overcommit1.
