Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 認定 NCP-DB 試験問題 (Q163-Q168):
質問 # 163
An administrator needs to patch Oracle DB engines, but the Update button is not present in the database server VMs. What could explain the current situation?
正解：B
解説：
In Nutanix Database Service (NDB), patching Oracle database engines requires the "Update" button to be available on the database server VM's management interface. If this button is missing, it typically indicates a configuration issue preventing NDB from performing the patching operation. The most common and critical reason is that the operating system (OS) credentials for the database server VM have not been set or registered with NDB. These credentials are necessary for NDB to authenticate and execute patching tasks on the VM, such as accessing the Oracle software and applying updates via a software profile.
* Option A is correct because missing OS credentials prevent NDB from establishing the required connection to the VM, disabling the Update button.
* Option B (Database parameters are missing) is incorrect because while database parameters are important for configuration, they do not directly control the visibility of the Update button for patching.
* Option C (Oracle DB engines cannot be patched) is incorrect as NDB explicitly supports patching Oracle databases when properly configured.
* Option D (Software profile is not published) is incorrect because an unpublished software profile might limit availability to users, but the Update button's presence relies on VM connectivity, not profile publication status.
To resolve this, the administrator must register valid OS credentials for the VM in NDB, enabling the patching functionality.

Within the NDB GUI, an administrator needs to set the shortest schedule interval possible for a database log catch up.
Which value, in minutes, will satisfy this requirement?
正解：B
解説：
The NDB GUI allows an administrator to set the schedule interval for a database log catch up, which is the process of collecting transaction logs periodically from the source databases and storing them in the time machine. The shortest possible value for this interval is 15 minutes, as per the NDB documentation1. This means that the NDB time machine will capture the database logs every 15 minutes and use them for backup, restore, clone, and refresh operations.

質問 # 165
How would an administrator enter the NDB command line to change the static IP address on the NDB VM?
正解：D
解説：
To change the static IP address on the NDB VM, an administrator would need to enter the NDB command line using the cerebro_cli command. The cerebro_cli command is used to access the Cerebro service, which is responsible for managing the NDB instance and its components. The cerebro_cli command can be run from the NDB VM or from any other VM that has network connectivity to the NDB VM.
The cerebro_cli command has various subcommands and options to perform different tasks, such as changing the IP address, hostname, password, or certificate of the NDB VM. To change the static IP address, the administrator would need to use the cerebro_cli network update subcommand with the appropriate parameters, such as the new IP address, netmask, gateway, and DNS servers. The cerebro_cli network update subcommand also requires the administrator to provide the current password of the NDB VM for authentication. After changing the IP address, the administrator would need to restart the NDB VM for the changes to take effect. References:

質問 # 166
Refer to the exhibit.
A request is received to provision a new Oracle SIHA DB & VM to test ASMLIB on OEL79 and Oracle 19c.
When walking through the provisioning workflow, only ASMFD is available in the ASM Driver drop down.
What is necessary to provision the requested SIHA DB and DB VM with ASMLIB?
正解：D
解説：
In the context of Nutanix Database Automation (NCP-DB), when provisioning a new Oracle SIHA DB & VM, if only ASMFD is available in the ASM Driver drop-down, it indicates that ASMLIB is not included in the current software profile. To provision the requested SIHA DB and DB VM with ASMLIB, it's essential to update the software profile to include the ASMLIB driver. This action will enable ASMLIB as an option in the ASM Driver drop-down during the provisioning workflow.

質問 # 167
An administrator needs to enable multi-cluster to setup NDB HA.
What should the administrator configure for the NDB Agent to satisfy this requirement?
正解：D
解説：
To enable multi-cluster setup for NDB High Availability (HA), the administrator must configure the NDB Agent with a Network Profile. A Network Profile defines the networking settings (e.g., VLANs, IP ranges) that the NDB Agent uses to communicate across clusters. This is critical for multi-cluster HA, as it ensures consistent network configuration for replication, failover, and data synchronization between clusters. The Network Profile must be properly configured to handle inter-cluster traffic and latency requirements (e.g.,
<25ms RTT).
Other options are irrelevant:
* A. Name Prefix: Used for naming conventions, not network configuration.
* C. Static VLAN: A component of a Network Profile, but not the full configuration needed.
* D. Compute Profile: Defines VM resources (CPU, memory), not networking for HA.
Thus, the verified answer is B, aligning with multi-cluster HA networking needs.
