An administrator is planning a disaster recovery strategy using Nutanix Leap. The production site has a 10-node cluster and the DR site has a 5-node cluster. The administrator needs to fail over 50 VMs. During a DR test, the failover succeeds, but the performance of the VMs at the DR site is poor. What is the most likely reason for the performance issue?
Show answer details
Correct answer: A
A common mistake in DR planning is undersizing the recovery site. While the DR site does not need to be a 1:1 match of the production site, it must have sufficient compute (CPU/RAM) and storage (capacity/performance) resources to run the critical workloads that will be failed over. In this case, concentrating the workload from 10 nodes onto 5 nodes likely resulted in resource contention, causing poor performance.

True or False: In a Nutanix cluster with a replication factor of 2 (RF2), data is considered resilient and the cluster can continue read/write operations immediately after a single node failure.
Show answer details
Correct answer: A
A replication factor of 2 means that two copies of all data exist on different nodes within the cluster. If a single node fails, one copy of the data becomes unavailable, but the second copy is still accessible on another node. The cluster remains operational, and the Curator process will automatically start replicating the data that lost a copy to restore it to RF2.

A system administrator is configuring a new AHV cluster and needs to ensure that the management interfaces for the CVM and AHV host are on a separate, more secure network than the guest VM traffic. Which feature must be configured to achieve this separation?

Correct answer: B
Network Segmentation is a security feature that separates different types of traffic onto different VLANs. Specifically, it is used to place the CVM/hypervisor management traffic on a dedicated backplane VLAN, isolating it from guest VM traffic and other network traffic. This enhances security and prevents guest VM traffic from impacting management operations.

An administrator receives a critical alert in Prism:
Metadata drive /dev/sdX is offline. The cluster is still operational. What is the most critical and immediate action the administrator should take?Show answer details
Correct answer: B
The metadata drive is critical for the operation of the Nutanix Distributed Storage Fabric. While the system is designed to handle such failures, improper remediation steps (like rebooting the host or CVM) can lead to a more severe outage. The standard and safest procedure for a metadata drive failure is to contact Nutanix Support immediately for guided assistance.

An organization wants to provide its development teams with a self-service portal to provision and manage their own VMs, but within strict resource limits. The IT department must retain oversight and control over the underlying infrastructure. Which combination of Prism Central features should be used to achieve this?
Show answer details
Correct answer: C
Projects in Prism Central are designed for multitenancy and self-service. They allow an administrator to allocate a specific set of resources (vCPU, memory, storage) to a group of users. Role-Based Access Control (RBAC) is then used to assign users (like developers) to a project with specific permissions, allowing them to create and manage VMs only within their allocated resource quotas.

A financial services company is deploying a new mission-critical OLTP database on a Nutanix AHV cluster. The primary requirement is to achieve a Recovery Point Objective (RPO) of zero and a Recovery Time Objective (RTO) of less than 5 minutes in case of a site-wide outage. The company has two data centers with a high-speed, low-latency (<5ms RTT) dark fiber link. Which Nutanix data protection feature should the architect recommend to meet these stringent requirements?
Show answer details
Correct answer: B
Metro Availability is the only Nutanix feature that provides synchronous replication, which is required to achieve an RPO of zero. By creating a stretched storage container across two sites and configuring a Witness VM, it can automatically failover in the event of a site failure, meeting the low RTO requirement. NearSync offers a low RPO (down to 1 minute) but not zero. Asynchronous and snapshot-based protection do not meet the RPO requirement.

An administrator is managing a mixed-workload Nutanix cluster with both VDI and server VMs. To improve storage performance for the VDI workload, they decide to enable inline compression and deduplication on the VDI storage container. After a week, they observe that while storage capacity savings are significant, the performance of some write-intensive server VMs has slightly degraded. What is the most likely cause of this performance degradation?
Show answer details
Correct answer: C
Inline deduplication is a CPU-intensive process. The Controller VM (CVM) on each node is responsible for managing storage services, including deduplication fingerprinting and metadata management. Enabling this feature, especially on a heavily utilized cluster, can increase CVM CPU usage. Since the CVM's Stargate process handles I/O for all VMs on that host, this increased overhead can introduce latency that affects other workloads, even those not on the deduplicated container.

A Nutanix administrator is tasked with implementing microsegmentation for a three-tier application using Flow Network Security. The goal is to ensure the web servers can only communicate with the application servers, and the application servers can only communicate with the database servers. Which of the following components must be configured to achieve this isolation? (Select THREE)
Show answer details
Correct answer: A, C, D

During a Life Cycle Manager (LCM) upgrade of the BIOS firmware on a cluster, one node fails the update process and is rolled back, while the others succeed. The administrator investigates and finds that the failed node's CVM is currently on a different host. Which AHV feature is most likely responsible for this situation and preventing the firmware upgrade?
Show answer details
Correct answer: A
CVM Autopathing is a high availability feature where a CVM can be live migrated to another host if its local host experiences a network failure, while its storage remains on the original host. LCM requires the CVM to be local to the host it is upgrading. The presence of the CVM on a different host indicates an Autopathing event has occurred, which must be resolved before the firmware upgrade can be successfully retried.

True or False: When creating a Volume Group on a Nutanix cluster to provide iSCSI storage, you must manually install and configure Nutanix Guest Tools (NGT) on the external client machine to enable the iSCSI initiator.
Show answer details
Correct answer: B
Nutanix Guest Tools (NGT) are installed inside virtual machines running on the Nutanix cluster to enhance management and integration. External clients connecting to a Volume Group via iSCSI are not VMs on the cluster and use their native operating system's iSCSI initiator. NGT is not applicable or required for these external clients.
