Nutanix Nutanix Certifications NCA-6.5 Questions & Answers

• Question 41:

  A company's security team has requested that all IT resources be hardened.

  What should an administrator do to increase the security of the Nutanix environment?

  A. Enable Cluster Lockdown

  B. Enable Prism Central KMS

  C. Enable Flow

  D. Enable STIG

  Correct Answer: D

  To increase the security of a Nutanix environment in response to a request from a company's security team, an administrator can Enable STIG (Security Technical Implementation Guide)

• Question 42:

  Refer to the exhibit.

  

  During VM creation, an administrator clicked on Add New NIC, but there is nothing in the Network Name dropdown list. What is causing this issue?

  A. No physical NICs have been allocated for user VMs

  B. The nodes nave no NiCs attached to them

  C. Only 1G NIC is attached to the Nutanix nodes

  D. A network was not created during Network Configuration

  Correct Answer: D

• Question 43:

  An organization runs several core business applications on a Nutanix cluster. System stability and support are critical for these applications, which has an annual maintenance window.

  How can the administrator assure that these requirements are met?

  A. Purchase Mission Critical support.

  B. Purchase Ultimate licensing.

  C. Adhere to the STS release cycle.

  D. Adhere to the LTS release cycle.

  Correct Answer: D

  To assure system stability and support for critical applications running on a Nutanix cluster, the administrator can adhere to the LTS (Long Term Support) release cycle. LTS releases provide stability and long-term support, with a focus on maintenance and bug fixes rather than new features. This can help ensure that the system remains stable and supported during the annual maintenance window

• Question 44:

  Which Nutanix data efficiency mechanism replaces a traditional Replication Factor for suitable data?

  A. Compression

  B. Deduplication

  C. Erasure Coding

  D. Intelligent Cloning

  Correct Answer: C

  Erasure coding is a data efficiency mechanism in Nutanix that replaces the traditional replication factor for suitable data. Erasure coding uses a technique known as "forward error correction" to spread data across multiple drives in a cluster, such that if some drives fail, the data can still be reconstructed. This allows for a much higher storage density and a more efficient use of disk space as compared to traditional replication, where multiple copies of the same data are stored across multiple drives. Deduplication and Compression are also data efficiency mechanisms in Nutanix which help to reduce the storage overhead by eliminating the redundant data. Intelligent Cloning is a Nutanix feature which helps to create multiple instant, space-efficient clones of a VM.

• Question 45:

  Within a Nutanix cluster an administrator is getting frequent failure alerts of the Cassandra and Stargate services for one of the nodes. What action will be taken by the cluster?

  A. Put host in Maintenance Mode

  B. Redirect I/O path to another CVM

  C. Remove the host from cluster

  D. Reboot Guest VMs to another hosts

  Correct Answer: A

  When the Cassandra and Stargate services fail frequently on a single node, the cluster will automatically put the host in Maintenance Mode to ensure the reliability and performance of the cluster. This will remove the node from the cluster's IO path and prevent any data loss or corruption.

• Question 46:

  An administrator has received the following critical alert:

  Node 192.168.148.172 is marked to be detached from metadata The administrator has opened a case with Nutanix and the support engineer has requested more information about the error. Which two actions should the administrator take in the Health Check dashboard to collect the requested information? (Choose two.)

  A. Create an Entity chart

  B. Open a remote support tunnel.

  C. Run the Log Collector

  D. Run the Nutanix Cluster Check

  Correct Answer: CD

• Question 47:

  Which address allows external connections to Nutanix storage presented by the Volumes feature?

  A. Prism Central IP

  B. Prism Central IP

  C. Data Services IP

  D. IPMI IP

  Correct Answer: C

  The Data Services IP address is the address that allows external connections to Nutanix storage presented by the Volumes feature. This address is used to access the storage from external sources and is used for replication and external snapshotting.

• Question 48:

  An administrator receives several alerts indicating a Nutanix cluster is running out of memory. As a preemptive measure, the administrator wishes to try to reduce the consumed resources, if possible.

  Which two predefined views for Reporting best display potentially reclaimable resources? (Choose two.)

  A. List of Inactive VMs

  B. list of Bully VMs

  C. Memory Runway

  D. List of Overprovisioned VMs

  Correct Answer: AD

  To display potentially reclaimable resources in a Nutanix cluster running out of memory, an administrator can use the List of Inactive VMs and List of Overprovisioned VMs predefined views for Reporting

• Question 49:

  Which VM-level feature ensures continuous availability of data?

  A. Replication Factor

  B. Data Locality

  C. Data Protection

  D. Deduplication

  Correct Answer: C

  Data Protection is a feature that ensures that data stored on a VM is protected against data loss in the event of hardware failure, data corruption, or other unexpected events. It typically includes features such as snapshots, replication, and backup, which enable administrators to create multiple copies of data and store them in different locations to provide redundancy and ensure availability. Replication Factor is a related concept, but it is not a VM-level feature in and of itself. Replication Factor is a setting that can be configured at the storage level to determine how many copies of data are stored on different nodes in a distributed storage system. Data Locality and Deduplication are also related concepts, but they do not directly ensure continuous availability of data.

• Question 50:

  An administrator has defined a security policy that needs to be applied to dozens of VMs. What is the most efficient way the administrator can perform this?

  A. Within the policy, select all the VMs it should be applied to.

  B. Apply a category to the VMs. and associate the category with the policy.

  C. Apply the same label to all the VMs, then bind the policy to the label.

  D. Use a script to apply the policy to the defined VMs.

  Correct Answer: C

  Labels allow administrators to group related objects, such as VMs, and then apply policies to those labels, rather than having to manually apply the policy to each individual VM. This is the most efficient way for an administrator to apply a security policy to dozens of VMs. Reference: https://portal.nutanix.com/page/documents/details?targetId=Platform-Administrator-Guide-v5_7:pag-sec-category-label-c.html
