Question 3
An administrator is deploying a new application to a Nutanix Enterprise Cloud. The application
requires a security to prevent unauthorized access. The application also uses many non-standard
ports that are unique to it. Security should not be changed for existing applications.

- A. Use existing categories for the VMs. and create new security policies to use the existing categories.
- B. Use existing categories for the VMs and modify existing security policies to include the specific port.
- C. Create new categories for the VMs, and create new security policies that include the new categories.
- D. Create new categories for the VMs, and modify existing security policies to include the new categories.
Answer:
C
Question 4
An administrator has a 32-node hybrid cluster with CPU, RAM and storage utilization of 80%. A
database VM is configured with VM Flash.
What is causing this IO latency?
- A. Controller VM is experiencing high CPU ready time.
- B. Curator scans causes by ILM constantly moving data.
- C. VM Flash Mode reduces SSD tier capacity for VMs.
- D. Database VM is experiencing high CPU ready time.
Answer:
A
Question 5
The networking team makes changes to the Top of Rack switches to which the Nutanix cluster are
attached. A few VMs are able to communicate with each other on the same node but are unable to
connect to other parts of the network.
What is the likely cause of this issue?
- A. There is a VLAN misconfiguration on the VMs.
- B. The vNIC port is disconnected on the affected VMs.
- C. There is a VLAN misconfiguration on the switch.
- D. Jumbo Frame are misconfigured across ports.
Answer:
C
Question 6
Refer
to
the
exhibit.
An administrator logged into Prism Element, notices the following in the home dashboard, and
showing the exhibit.
Which action should the administrator take next?
- A. Configure the fqdn for the hosts indicated
- B. Troubleshoot the zookeeper server issue
- C. Re-run NCC specifying data_resiliency_check
- D. Check the hardware page for disk failures
Answer:
C
Question 7
A customer has a four-node cluster and is using Volume Groups to provide storage services to a SQL
cluster.
In the event of a CVM failure in the cluster, what is the expected IO path of the volume groups iSCSI
targets?
- A. vDisk directed at failure CVM are redirected to Data Services IP until CVM is reconnected
- B. vDisk directed to CVM that failed to disconnect and will not reconnect without manual intervention
- C. vDisk directed to failed CVM are redirected to another CVM and automatically reconnect
- D. vDisk directed at failed CVM will disconnect and reconnect when the failed CVM comes back online
Answer:
C
Question 8
A customer has the following requirement for a Nutanix cluster:
Must support high-performance Nutanix Volumes iSCSI workloads
Must utilize AHV nodes
Must use 10 GbE interface
How should the customer optimize networking?
- A. Enable Jumbo Frame on just the Host
- B. Convert Cluster to ESXi and enable Jumbo Frame on Host and CVM
- C. Enable Jumbo Frames on just the CVM
- D. Enable the use of Jumbo Frame on Host and CVM
Answer:
A
Question 9
An administrator configure Active Directory (AD) authentication for their Nutanix environment.
When login in using an AD user account, the login process takes more than one minute to complete.
No delay occurs when logging a local account.
What should the administrator confirm to resolve this issue?
- A. The user search base for the group is configured correctly
- B. The domain controller being used is configured as a global catalog server.
- C. Active directory lookups are configured to use Non-Recursive mode.
- D. The service Account Username is correct for the domain.
Answer:
C
Question 10
Refer to the exhibit.
An administrator receive the warning massages shown in the exhibit while validating cluster
conversion from EXSi to AHV.
What should the administrator do to address this warning in v Center Server?
- A. Keep active adapters od different speeds as active standby
- B. Remove adapters that are active but not homogeneous.
- C. Keep homogeneous adapter as active and standby
- D. Remove the standby adapters under Teaming and Failover.
Answer:
C
Question 11
