NEW QUESTION # 90
An administrator is setting up an NDB VM in a highly segmented environment in which only specific ports are allowed.
Before deploying the NDB VM, which two options identify ports that must be open to the Controller VMs (CVMs)? (Choose two.)
Answer: A,D
Explanation:
NDB requires management and storage connectivity to a registered Nutanix cluster. TCP 9440 carries Prism REST API communication between NDB components and the Nutanix cluster. TCP 3205 and 3260 support iSCSI redirection/data and standard iSCSI control traffic used when NDB attaches Volume Group disks.
Therefore, both option B and option D must be allowed through the segmented network. Port 443 is used for HTTPS communication in other NDB paths, but it is not the required Prism/CVM port represented by this question. Ports 1433 and 5432 are database listener ports for Microsoft SQL Server and PostgreSQL, respectively, rather than NDB-to-CVM infrastructure ports. The source answer "D" is incomplete; the verified answer is B and D. Nutanix port reference
NEW QUESTION # 91
What is purpose of the NDB Database Agent service?
Answer: B
Explanation:
The correct answer is C because the NDB Database Agent service is responsible for scheduling and monitoring the NDB-related operations, such as provisioning, patching, cloning, and restoring databases. The NDB Database Agent service is deployed on the NDB server and on each of the database server VMs provisioned by NDB. It contains the tools required to perform each task and communicates with the NDB server through the NDB API. The other options are not correct because they describe different components or functions of the NDB solution. Option A is not correct because the transaction logs are not stored by the NDB Database Agent service, but by the NDB Time Machine service, which is a distributed file system that stores the database snapshots and logs. Option B is not correct because the source databases are not hosted by the NDB Database Agent service, but by the database server VMs, which are virtual machines that contain an instance of the database engine software and the database files. Option D is not correct because the NDB Database Agent service does not contain an instance of the database engine software, but only the tools required to perform the NDB-related operations. The database engine software is installed on the database server VMs, which are provisioned by NDB using the profiles defined by the administrator.

NEW QUESTION # 92
An NDB administrator wants to configure object storage for database log backups.
What step must be completed first to enable Nutanix Objects for use in NDB?
Answer: C
Explanation:
Prism Central registration is the prerequisite that makes Nutanix Objects discoverable and manageable by NDB. Nutanix states that one or more Prism Central domains must be registered with NDB before an Object Store can be provisioned or registered. Once that relationship exists, the administrator can select the appropriate Prism Central and Object Store from the NDB workflow and then configure the store for database log backups. Registering an S3-compatible store is a later object-store onboarding step, not the initial prerequisite. An NC2 deployment is optional, and directly registering only the Prism Element instance hosting Objects does not satisfy the documented integration sequence. Therefore, option C is correct. The candidate file's supplied answer D conflicts with the official prerequisite and has been corrected. Nutanix Prism Central registration documentation
NEW QUESTION # 93
An administrator is preparing to deploy NDB in a High Availability configuration so that the NDB control plane is distributed across different sites and protected against a failure at the primary data center.
Which prerequisite must be met before enabling NDB High Availability?
Answer: D
Explanation:
NDB High Availability distributes control-plane components across three Nutanix clusters so that a single cluster or site does not become the sole failure domain. For deployments spanning separate data centers or sites, the supported round-trip time between the selected clusters must be less than 25 milliseconds. A two- cluster topology is not supported because the cluster hosting two API servers and two repository servers would remain a single point of failure. Option C is also too restrictive: the three clusters may use AHV or ESXi; they are not required to be three AHV clusters. Consequently, option A is correct. The List B answer of D, which states less than 5 milliseconds, conflicts with Nutanix's documented HA requirement and has been corrected. Nutanix NDB HA architecture
NEW QUESTION # 94
An administrator needs to provision a 3-node MSSQL Server AG with the following configuration:
* Two database server VMS including the primary replica on a local site
* A third database server VM on a remote site
How many IP addresses will the network at each site require?
Answer: D
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.
