NEW QUESTION # 20
What data is stored as a file on storage devices owned by a CVM?
- A. Storage Pool
- B. Container
- C. Extent Group
- D. vDisk
Answer: D
Explanation:
A vDisk is a file that is stored on storage devices owned by a CVM. A vDisk represents a virtual disk that is attached to a VM or a CVM. A Storage Pool is a logical grouping of physical disks in a cluster. An Extent Group is a collection of data blocks that belong to a vDisk. A Container is a logical grouping of vDisks that share the same storage policies and settings. Reference: https://www.nutanix.com/content/dam/nutanix/resources/misc/ebg-nca-6-5.pdf (pages 31-32)
NEW QUESTION # 21
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. Only 1G NIC is attached to the Nutanix nodes
- B. A network was not created during Network Configuration
- C. The nodes nave no NiCs attached to them

NEW QUESTION # 22
A single host in a four-node AHV-based cluster experiences a complete network failure.
If more than enough resources exist in the cluster to tolerate a node failure, what happens to the user VMs running on that host?
- A. VMs remain down until network connectivity is restored.
- B. VMs automatically restart on the three remaining hosts.
- C. VMs stay up, but are unreachable until connectivity is restored.
- D. VMs are live-migrated to the three remaining hosts.
Answer: D
Explanation:
If a single host in an AHV-based cluster experiences a complete network failure, and if there are enough resources available in the cluster to tolerate a node failure, then the user VMs running on the failed host will be automatically live-migrated to the remaining three hosts in the cluster. This ensures that the VMs stay up and running even if one of the hosts fails.

NEW QUESTION # 23
An administrator needs to expand a Nutanix cluster that is tagging the network traffic at the CVM and AHV level. However, the administrator doesn't remember the configured VLAN ID.
Which command can the administrator run to find the correct VLAN ID from the CVM?
- A. ifconfig
- B. acli
- C. manage-ovs
- D. ovs-vscl
Answer: D
NEW QUESTION # 24
On which entity is Replication Factor configured?
- A. Volume
- B. Oplog
- C. Host
- D. Container
Answer: D
Explanation:
Replication Factor is configured on a Container entity. Containers group together virtual disks and files, and allow administrators to set policies on a group level. This allows for increased flexibility in managing storage resources and allows administrators to easily set policies across multiple virtual disks and files.
Replication Factor is configured on Containers. A container is a logical grouping of one or more storage pools and defines the storage resources available to virtual machines. The replication factor is a setting that determines the number of copies of data that are stored across the cluster. By configuring the replication factor on a container, you are setting the number of copies of data that will be stored for all virtual machines that are associated with that container.
For example, if you have a container with a replication factor of 3, it means that three copies of data will be stored across the cluster, and two copies are required to reconstruct the data in case of a failure.
NEW QUESTION # 25

Which directory should the LCM Framework Bundle be extracted to on a dark site web server in order to update the LCM Framework?
- A. upgrade
- B. install
- C. software
- D. release
Answer: D
Explanation:
When updating the LCM Framework on a dark site web server, the LCM Framework Bundle should be extracted to the "release" directory. This directory is specifically designated for holding the updated LCM Framework files, and the update process will look for the files in this location. Extracting the bundle to a different directory, such as "upgrade", "software" or "install" would not be sufficient as the LCM Framework update process may not be able to find the files.

- A. Sets the metadata tier preference to SSD
- B. Sets the storage tier preference to SSD
- C. Sets the metadata tier preference to HDD
- D. Sets the storage tier preference to HDD
Answer: B
Explanation:
Enabling Flash Mode will set the storage tier preference to SSD, meaning that data will be stored on the high-performance SSD storage tier. Flash Mode is designed to speed up the performance of applications by ensuring that the most frequently used data is stored on the faster storage tier.
