Nutanix Certified Services Core Infrastructure Professional 認定 NCS-Core 試験問題:

1. A customer buys ultimate licensing and wants to use the built-in Nutanix software encryption on their new AHV cluster. The customer needs to create three storage containers and asks the consultant to complete the process as fast as possible.
In which order should the cluster be deployed?

A) Create Cluster -> Install License Key -> Create Storage Containers -> Encrypt Cluster
B) Create Cluster -> Encrypt Cluster -> Install License Key -> Create Storage Containers
C) Create Cluster -> Create Storage Containers -> Encrypt Cluster -> Install License Key
D) Create Cluster -> Install License Key -> Encrypt Cluster -> Create Storage Containers

2. An administrator needs to make sure an RF3 cluster can survive a failure of two complete racks without negatively affecting performance. The current cluster configuration consists of the following:
* 30 All Flash Nodes: distributed 10 nodes per rack across three 42U racks
* Each node is configured with 20TB usable storage all flash (Cluster Total 600TB Usable)
* Current cluster utilization is 500TB storage
* Storage containers have Erasure Coding enabled
Which configuration changes should be made to make sure the cluster meets the requirements?

A) Expand the cluster to 48 nodes distributed evenly across 6 racks
B) Expand the cluster to 50 nodes distributed evenly across 5 racks
C) Expand the cluster to 60 nodes distributed evenly across 6 racks
D) Expand the cluster to 40 nodes distributed evenly across 5 racks

3. An administrator receives reports that VDI desktop performance in an 8-node Nutanix VDI environment is poor. Opening applications takes between 1 and 2 minutes.
When investigating the issue, the following conditions are found:
* Cluster memory utilization: 80%
* Cluster SSD utilization: 70%
* Average VM CPU Wait Time: 11%
* CVM CPU utilization: 75%
Which action should be taken to improve VDI performance?

A) Increase the amount of SSD storage in the cluster.
B) Add memory to the nodes in the cluster.
C) Add CPU resources to the cluster.
D) Increase the number of vCPU cores allocated to the CVM.

4. An administrator needs to replace the self-signed certificate on a cluster. Which two requirements must be met as part of the process? (Choose two.)

A) The imported files for the custom certificate must be PEM encoded.
B) The signed, intermediate and root certificates are chained.
C) The cluster administrator must restart the interface gateway.
D) The existing certificate must be deleted prior to replacement.

5. A customer has NearSync configured. When the administrator tries to restore a snapshot from 3 minutes ago, it is not available. The snapshots are happening at 15-minute intervals instead of at the 5-minute configured interval. When the protection domain was initially set up, the snapshots were happening at the expected 5- minute interval.
What should the customer do to enable the snapshots to happen at the expected interval?

A) Utilize Metro Availability to meet this requirement
B) Change the protection domain to use Async DR
C) Configure the protection domain to take snapshots on 15-minute intervals
D) Fix a connectivity issue because the protection domain reverted to Async
