Nutanix Nutanix Certifications NCA-6.5 Questions & Answers

• Question 91:

  An administrator needs to deploy a two-node cluster on a new ROBO Site. What is required to maintain High Availability in the case of a node failure?

  A. Witness VM

  B. Metro-Availability

  C. Windows Failover Clustering

  D. Async Replication

  Correct Answer: A

  To maintain high availability in the case of a node failure in a two-node cluster, a Witness VM is required. Therefore, the correct answer is A. The Witness VM acts as a tie-breaker and arbitrator in the event of a split-brain scenario, where both nodes lose connectivity to each other, to ensure that only one node continues to operate and serve workloads. It is also recommended to use a high-performance network to minimize network latency between the two nodes and the Witness VM.

• Question 92:

  An application owner had reported that an AHV-based critical application VM is performing very slowly. After initial diagnostics, it has been observed that the CPU utilization is significantly higher than normal.

  What two actions should the administrator take on this VM without shutting it down? (Choose two.)

  A. Increase number of vCPU in Prism Element

  B. Configure additional cores in acli

  C. Ensure CPU hot-add is supported by the Guest

  D. Use PrismElement to increase the number of cores

  Correct Answer: AC

• Question 93:

  What resource should be used to ensure a successful upgrade of the hypervisors and AOS within a vSphere-based Nutanix cluster?

  A. Upgrade Paths

  B. Field Advisories

  C. Compatibility and Interoperability Matrix

  D. Hardware Replacement Documentation

  Correct Answer: C

  The Compatibility and Interoperability Matrix (CIM) is the resource that should be used to ensure a successful upgrade of the hypervisors and AOS within a vSphere-based Nutanix cluster. The CIM provides information about the compatibility

  and interoperability of the different components of the Nutanix cluster, including the hypervisors, AOS, and other related components.

• Question 94:

  An administrator needs to check which users have created VMs within the previous two weeks.

  How can the administrator satisfy this task?

  A. Create a filter in Prism Central Audits page

  B. CSV export Events list from Prism Central page

  C. Sort operation messages in Prism Element Tasks page

  D. Use Analysis Page in Prism Element and adjust time range

  Correct Answer: A

• Question 95:

  Which feature in Pulse helps secure a customer's private information?

  A. Security Central

  B. Cluster Lockdown

  C. Data-at-rest Encryption

  D. Data Obfuscation

  Correct Answer: D

  Data Obfuscation is a feature in Pulse that helps secure a customer's private information by obfuscating the data before it is sent to Nutanix. This ensures that any data sent to Nutanix is not visible to anyone other than the customer, and helps protect sensitive data from unauthorized access or malicious actors.

• Question 96:

  Which two advanced features requires you to install Nutanix Guest Tools (NGT)? (Choose two.)

  A. Disaster Recovery of a VM between AHV and ESXi Hypervisors

  B. Live Migration of a VM between AHV and other Hypervisors

  C. File recovery from a third-party backup

  D. Self-service file-level recovery from VM snapshots

  Correct Answer: AD

• Question 97:

  What is the biggest benefit of the Redfish Protocol and LCM?

  A. HBA and NIC card update twice as quickly

  B. AOS and AHV update twice as quickly

  C. BMC and BIOS update twice as quickly

  D. SSD and HDD update twice as quickly

  Correct Answer: C

  The Redfish Protocol and Lifecycle Manager (LCM) provide the biggest benefit of allowing BMC and BIOS updates to be done twice as quickly as before. This is because Redfish and LCM allow for updates to be done in parallel, rather than serially, which reduces the amount of time it takes for an update to be completed.

• Question 98:

  What is the purpose of Discoveries within the Nutanix Support Portal?

  A. To identify clusters that are affected by known issues.

  B. To provide an audit trail of cluster logins.

  C. To identify VMs that require OS updates or patching.

  D. To provide forecasting of cluster resource utilization.

  Correct Answer: A

  Discoveries within the Nutanix Support Portal are used to identify clusters that are affected by known issues. This can help Nutanix Support quickly identify and address any potential problems that may be caused by a specific issue.
