NEW QUESTION # 117
Which default roles are available within Era for Role-Based Access Control?
Answer: B
Explanation:
Nutanix Era offers Role-Based Access Control capabilities by organically embedding them in the product. It provides the ability to add and remove users from Era, create and assign roles to users, and associate various privileges with a role1. The default roles available within Era for Role-Based Access Control are:
* prism Admin
* Era Super Admin
* Era Database Admin
* Era Infrastructure Admin1 These roles allow for the management of both physical resources like IP addresses and VLANs along with database entities like databases, time-machines, clones, and so on1.
NEW QUESTION # 118
How can NDB updates be downloaded for a dark site?
Answer: A
Explanation:
A "dark site" refers to an environment with no internet connectivity, requiring manual processes for software updates. For Nutanix Database Service (NDB) in such a setup, updates cannot be downloaded automatically from the internet. The correct procedure is to:
Download the upgrade bundle: Access the Nutanix Support Portal from a system with internet access and download the NDB upgrade bundle specific to the version (e.g., v7.5 or later).
Manually upload it to the NDB server: Transfer the bundle to the NDB server (e.g., via SCP or USB) and upload it through the NDB interface under the "Software Updates" or "Maintenance" section.
Other options are incorrect in a dark site context:
B: The "Administrator > Maintenance" section allows initiating updates, but it cannot download files without internet access.
C: Changing the network to access https://download.nutanix.com defeats the dark site's isolation and is impractical.
D: Uploading to Prism Element > Images is for VM images or other Prism-specific content, not NDB software updates.
Thus, the verified answer is A, aligning with Nutanix's documented process for dark site updates.

NEW QUESTION # 119
An administrator has received a request to clone a source production database to an existing development server.
Which two actions must be taken to complete this task?
Answer: A,B
Explanation:
According to the Nutanix Database Automation (NCP-DB) Learning documents12, to clone a source production database to an existing development server, the following actions must be taken:
A: The development server must be registered by Era in order to receive the clone1. This is because Nutanix Era is a database management tool that manages the lifecycle of databases and their copies. Registering the development server with Era allows it to manage the database on that server.
D: The development server must have the IP and credentials provided during cloning2. This is necessary for Era to access the development server and perform the cloning operation. The IP address and credentials are used to establish a connection to the development server. Without these details, Era would not be able to access the server and perform the cloning operation.
NEW QUESTION # 120
The container used for provisioning databases and deploying NDB is named NDB.
What should the administrator do before registering the cluster?
Answer: D
Explanation:
Comprehensive and Detailed 100 to 150 words of Explanation From Nutanix Database Management & Automation (NDMA) topics:
NDB cluster registration must account for storage containers associated with resources that need to be available during cross-cluster operations. Although the NDB control-plane VM and database provisioning operations use the same NDB container in this scenario, NutanixManagementShare is a separate Nutanix- managed service container. Its corresponding remote-container relationship must therefore be represented through storage mapping. Mapping the NDB container to default-container is unnecessary because the NDB server and provisioning storage are already consolidated. Removing SCSI disks from the NDB VM would damage the appliance configuration, while an attached CD-ROM does not justify altering the required storage mapping. This differs from the existing questions, which ask when mapping is required because the NDB server and provisioning containers are separate. Therefore, option A is correct.

NEW QUESTION # 121
A Log Catchup gap has occurred, impacting the ability to perform point-in-time restore (PITR) operations to create a clone or perform a database restore.
Which two statements below are true for the NDB Time Machine Heal Snapshot feature? (Choose two.)
Answer: B,D
Explanation:
A Log Catchup gap in Nutanix Database Service (NDB) occurs when transaction logs are missing or corrupted, disrupting point-in-time restore (PITR) operations for cloning or database restoration via Time Machine. The NDB Time Machine Heal Snapshot feature addresses this by repairing snapshots to resolve such gaps.
* Option A (By default the time machine auto-heal feature is enabled) is incorrect because the auto- heal feature is not enabled by default; it requires explicit configuration or manual invocation.
* Option B (Manual Heal is only used when gaps in Log Catchup are detected once the operation has begun failing) is incorrect because manual heal can be initiated proactively or reactively, not solely after failure detection.
* Option C is correct because a successful Time Machine Heal process restores the snapshot integrity, allowing PITR to span the previously gapped period.
* Option D is correct as the auto-heal process, when enabled, runs every 5 minutes to detect and address healable conditions, aligning with NDB's automated maintenance schedule.
Together, C and D reflect the operational mechanics of the Heal Snapshot feature.
