An administrator configures authentication in Prism Central (PC) for the NTNX-Admins group. Users report that they are unable to log in. The administrator confirms that the Active Directory (AD) settings in PC are correct.
Which condition could result in this behavior?
- A . A role mapping needs to be associated with the AD group.
- B . The users must be added to the Domain Admins AD group.
- C . The Local authentication type must also be selected in PC.
- D . A client chap certificate must also be added in PC.
An organizations Nutanix Cluster is based on VMware vSphere. The cluster is configured to download
software updates automatically. The administration needs to verify and eventually upgrade VMware hypervisor via Prism Ul.
After logging in to Prism, the administrator receives the message shown:
No available versions for upgrade
What is causing the current state?
- A . VMware support has expired, so downloads are not available.
- B . vSphere binaries need to be manually uploaded.
- C . The environment is running the latest vSphere version, so no update is required.
- D . The cluster is unable to connect to reIease-api.nutanix-ccm:8D.
An administrator receives an error indicating that the CVMs in the cluster are not syncing to any NTP servers.
An investigation of the issue finds:
• The NTP servers are configured in Prism
• The time on all CVMs is the same
• Both the CVMs and AHV hosts are configured for the UTC time zone
Which two steps can be taken to troubleshoot this issue? (Choose two.)
- A . Confirm that the NTP servers are reachable from the CVMs.
- B . Restart genesis on all CVMs.
- C . On a CVM. run the command a Hash ntpq -pn.
- D . Restart the chronos service on all CVMs.
An administrator is implementing a VDI solution. The workload will be a series of persistent desktops in a dedicated storage container within a four-node cluster. Storage optimizations should be set on the dedicated storage container to give optimal performance including during a node failure event.
Which storage optimizations should the administrator set to meet the requirements?
- A . Compression, Deduplication, and Erasure Coding
- B . Deduplication and Erasure Coding
- C . Compression and Deduplication
- D . Compression only
Refer to the exhibit.
A Nutanix host is connected as shown in the exhibit with br0-up set to active/backup. Physical Switch 1 experiences a power outage causing br0-up to failover to using eth2. The CVM and host become inaccessible. User VMs restart on other hosts in the cluster, which causes a disruption to those VMs.
Which configuration issue likely caused this outage?
- A . Bridge br0-up should be configured to use balance-tcp rather than active/backup.
- B . The CVM should have eth1 connected to the OVS.
- C . The upstream port for eth2 is missing a VLAN.
- D . The user VMs only have one NIC
An administrator is configuring software only. Data-at-Rest Encryption on their Nutanix cluster. They are planning to deploy a third-party key management server (KMS).
Where should this server be hosted?
- A . As a single VM on the Nutanix cluster
- B . On hardware external to the Nutanix duster
- C . As a clustered VM setup on the Nutanix cluster
- D . As a single VM deployed on the host that contains the Prism leader CVM
An administrator recently added VLAN 205 CRM in Prism Element. The workloads attached to the associated NICs are unable to establish network connectivity.
Which Layer 2 protocol allows the administrator to troubleshoot this issue from Prism Element?
- A . HDLC
- B . SUP
- C . LACP
- D . LLDP
An administrator is deploying an application that requires maximum I/O throughput for scratch data. The administrator is concerned that the throughput requirement is greater than what can be provided by a single cluster node.
What should the administrator do to meet this requirement?
- A . Create a volume group with several virtual disks and attach to the VM
- B . Create a volume group with one virtual disk attached to the VM
- C . Create a virtual disk attached to the VM’s PCI interface
- D . Create several virtual disks attached to the VM’s virtual SCSI controller
An administrator is deploying several new application VMs to a Nutanix cluster. The application is very transactional with a 28/72 random, read/write ratio.
What should the administrator do?
- A . Add a minimum of four SSDs to each node to ensure all writes go to the SSDs.
- B . Add a minimum of four virtual disks to each VM, and aggregate them on guest OS level.
- C . Add one large SSD to each node and enable Flash Mode for the VMs.
- D . Add one large virtual disk to each VM. and use it for all application data.
An administrator needs to relocate an AHV cluster to a new datacenter during a maintenance window. The cluster will use the same IPs in the new datacenter.
Which two steps should be taken to prepare for this task? (Choose two.)
- A . Stop all Nutanix Files clusters
- B . Relocate the linked LDAP servers
- C . Shut down all user VMs in the cluster
- D . Reconfigure IPMI for the new datacenter
