NCP-DB Practice Test

C.   The VLAN is stretched

Explanation:
The correct answer is C because a stretched VLAN is a VLAN that spans across multiple Nutanix clusters, which may cause network conflicts or latency issues when starting the database server. Option A is incorrect because a DHCP VLAN is a VLAN that uses dynamic IP address allocation, which does not affect the database server startup. Option B is incorrect because a static VLAN is a VLAN that uses fixed IP address allocation, which also does not affect the database server startup. Option D is incorrect because IPAM is not a type of VLAN, but a feature of NDB that allows managing IP addresses for database servers and databases.

C.   Base-64 encoded X 509

Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, Nutanix Era supports x509 certificates in Base-64 encoded PEM format1. This format is used when an administrator needs to replace the default Nutanix self-signed certificates in Era1.

B.   Japanese

Explanation:
The NDB user interface supports multiple languages, including English, Chinese, and Japanese. You can change the language preference in the NDB settings page. The NDB user interface does not support Korean, French, or German languages at this time.

A.   Tags

Explanation:
Nutanix Era allows custom metadata to be assigned to entities (clones, time machines, databases, and database servers) by using Tags. Tags are a component of Nutanix Era that allows users to assign custom metadata to various entities, enhancing the ability to organize, search, and manage these entities within the Era platform1.

D.   Cluster VIP end I Listener IP on the local site
1 Cluster VIP and 1 Listener IP on the remote site
2 IPs in the local site and 1 on the remote site for the database server nodes

Explanation:
The correct answer is D. When setting up a 3-node MSSQL Server AG with two database server VMs on a local site and a third database server VM on a remote site, the network at each site will require the following IP addresses:

• 1 Cluster VIP and 1 Listener IP on the local site123.
• 1 Cluster VIP and 1 Listener IP on the remote site123.
• 2 IPs in the local site and 1 on the remote site for the database server nodes123.

This configuration ensures that each node in the cluster has a unique IP address, and each cluster and listener also has a unique IP address. This is necessary for the proper functioning of the cluster and to ensure that all nodes can communicate with each other and with clients123.
