NEW QUESTION # 23
An administrator has recently expanded the Nutanix cluster and noticed that NCC health checks and alerts for newly-added nodes are not being received via email.
What should administrator do to resolve this issue?
- A. Run NCC Health Check
- B. Reboot Nutanix cluster
- C. Configure SMTP
- D. Add CVM IP in SMTP Relay
Answer: C
Explanation:
In order to resolve the issue of not receiving NCC health checks and alerts for newly-added nodes via email, the administrator should configure SMTP (Simple Mail Transfer Protocol) settings. SMTP is used to send email notifications from the Nutanix cluster, and if it is not configured properly, the health checks and alerts will not be sent via email. The administrator should check the SMTP settings in the Prism web console and ensure that they are correct and that the correct email address is specified for receiving notifications. This will ensure that the health checks and alerts for the newly-added nodes are sent to the correct recipient.
NEW QUESTION # 24
An administrator receives an alert that a node has failed within a Nutanix AHV-based 10-node cluster. Before the failure, the cluster CPU and memory utilization was around 50%.
What actions will the cluster automatically take?
- A. VMs will migrate to other nodes in the cluster with no user impact.
- B. The cluster will enter read-only mode and the VMs will be powered down to preserve data.
- C. VMs will be unavailable until the affected host is fully functional.
- D. All HA-protected VMs will be automatically restarted on other nodes in the cluster.
Answer: A
Explanation:
In a Nutanix AHV-based cluster, if a node fails, the cluster will automatically take actions to ensure high availability of the virtual machines. The cluster will automatically live migrate the VMs running on the failed node to other healthy nodes in the cluster without any user impact, this process is known as "Failover" . The live migration process ensures that the VMs are restarted on another node in the cluster as soon as possible with minimal interruption to the users. The cluster CPU and memory utilization being around 50% at the time of failure does not affect the failover process.

NEW QUESTION # 36
Which cluster configuration is LCM unable to perform firmware upgrades against?
- A. Two - node
- B. Five-node
- C. Single-node
- D. Three-node
Answer: C
Explanation:
LCM (Lifecycle Manager) is a tool provided by Nutanix to automate software and firmware upgrades for Nutanix clusters. However, LCM is unable to perform firmware upgrades against a (D) Single-node cluster configuration.
This is because a single-node cluster does not have any redundancy, so there is no way to perform an upgrade without taking the entire cluster offline. In contrast, multi-node clusters can typically be upgraded in a rolling fashion, with one or more nodes being upgraded at a time while the rest of the cluster remains online.
LCM is capable of performing firmware upgrades against two-node, three-node, and five-node cluster configurations, as long as they meet the other requirements for LCM support (such as being on a supported AOS release and having the appropriate network connectivity).
NEW QUESTION # 37
A Cluster is Experiencing an occasional issue that does not impact production services.
Which support case priority level should be assigned?
- A. P3 - Normal
- B. P2 - Critical
- C. P4 - Low
- D. P1 - Emergency
Answer: A
Explanation:
According to Nutanix Support Best Practices, P3 cases are designated for issues that have a moderate business impact or affect non-production systems. P3 cases are intended for issues that are important but not critical, and the issue can be deferred while continuing with normal business operations. Examples of P3 cases include software defects, minor configuration issues, or minor hardware problems.
NEW QUESTION # 38
Refer to the exhibit.
After an abrupt power outage, an administrator receives a number of alerts indicating disks are failed. Prism Element shows a large number of disks offline as seen in the diagram. This single block, four node cluster is configured FT1 with an RF2 container holding all user data.
What number of drive failures on different domains (node, block, or rack) could this configuration have tolerated prior to seeing data unavailability?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
This single-block, four-node cluster is configured with Fault Tolerance 1 (FT1) and a Replication Factor of 2 (RF2). This means that the data is replicated across two domains (node, block, or rack). Thus, the cluster can tolerate up to two drive failures on different domains before seeing data unavailability. Reference: https://portal.nutanix.com/page/documents/details?targetId=Prism-Admin-Guide-v5_6:pr-data-protection-replication-factor-c.html This single block, four node cluster is configured with Fault Tolerance (FT1) and a Replication Factor (RF2) container holding all user data. FT1 means that there are two copies of data stored across the cluster, and RF2 means that there are two copies of data stored in the container. This configuration can tolerate 2 drive failures on different domains (node, block, or rack) prior to seeing data unavailability.
With FT1, if a drive fails, the second copy of the data is still available and can be used to reconstruct the data. With RF2, if a drive fails, the second copy of the data is still available and can be used to reconstruct the data. However, if a drive failure occurs on a different domain (node, block, or rack) from the one containing the other copy of data, the second copy of the data is still available, but the data availability may be affected.
It's important to note that this is the maximum drive failures that the configuration can tolerate, and it's recommended to have a disaster recovery plan in place in case of a drive failure, to ensure the data availability and integrity.
You can find more information on this topic in the Nutanix Administrator Guide, which is available on the Nutanix support website https://portal.nutanix.com/#/page/docs/details?targetId=Admin-Guide-Prism-v5_24:Admin-Guide-Prism-v5_24
NEW QUESTION # 39
Which option is available for an administrator to upload a remote disk file to Image Configuration?
- A. FTP
- B. SCP
- C. SFTP
- D. HTTP
Answer: C
Explanation:
SFTP (Secure File Transfer Protocol) is an option available for an administrator to upload a remote disk file to Image Configuration. SFTP is a secure protocol that ensures that the data being transferred is encrypted and is therefore more secure than other transfer protocols such as FTP or HTTP.

NEW QUESTION # 40
What type of relationship does a VM Affinity policy define?
- A. VM to Network VLAN
- B. VM to Storage tier
- C. VM to VM
- D. VM to Host
Answer: D
Explanation:
The type of relationship that a VM Affinity policy defines is VM to Host. A VM Affinity policy is used to specify which host a virtual machine should be placed on. This can be used to ensure that certain VMs are always running on the same host for performance or availability reasons. Additionally, VM Affinity policies can also be used to ensure that VMs are spread across multiple hosts for better load balancing.
NEW QUESTION # 41
How is the destination cluster determined when uploading images from the local workstation to Prism Central?
- A. Selected sequentially
- B. Selected randomly
- C. Selected manually
- D. Selected alphabetically
Answer: D
Explanation:
When uploading images from a local workstation to Prism Central, the destination cluster is determined based on the alphabetical order of the cluster names. Specifically, the first available cluster in alphabetical order is selected as the destination for the image upload.
This behavior is documented in the Prism Central Admin Guide, which states that when you upload an image to Prism Central, "the image is stored in the first cluster that has sufficient space and starts with the letter that appears first in the image name."
NEW QUESTION # 42
What is the minimum number of blocks required to utilize block awareness?

Answer: C
NEW QUESTION # 43
Which Nutanix data efficiency mechanism replaces a traditional Replication Factor for suitable data?
- A. Deduplication
- B. Erasure Coding
- C. Compression
- D. Intelligent Cloning
Answer: B
Explanation:
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.

NEW QUESTION # 44
Which VM-level feature ensures continuous availability of data?
- A. Deduplication
- B. Data Locality
- C. Data Protection
- D. Replication Factor
Answer: C
Explanation:
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.
