Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 認定 NCP-DB 試験問題 (Q121-Q126):

質問 # 121
A database administrator wants to define initialization variables for different types of database engines and workloads, like OLTP and DW.
What type of profile would be used?

A. Database Parameters
B. Network
C. Compute
D. Software Profile Version

正解：A

解説：
The database parameters profile is used to define the initialization variables for different types of database engines and workloads, such as OLTP and DW. The database parameters profile allows the database administrator to customize the configuration settings for each database engine, such as Oracle, SQL Server, PostgreSQL, and MySQL. The database parameters profile can also be applied to different database operations, such as provisioning, cloning, and patching. The database parameters profile helps to optimize the performance and functionality of the databases according to the specific requirements and best practices of each database engine and workload.
The software profile version is used to define the software version and edition for each database engine, such as Oracle 19c Enterprise Edition or SQL Server 2019 Standard Edition. The software profile version is required for provisioning new databases and patching existing databases. The software profile version helps to ensure the compatibility and compliance of the databases with the supported software versions and editions.
The network profile is used to define the network configuration and security settings for the database server VMs and the databases, such as the IP address, subnet mask, gateway, DNS, firewall rules, and SSL certificates. The network profile is required for registering new database server VMs and provisioning new databases. The network profile helps to ensure the connectivity and protection of the database server VMs and the databases within the network environment.
The compute profile is used to define the compute resources and storage policies for the database server VMs and the databases, such as the CPU, memory, disk size, disk type, compression, deduplication, and replication factor. The compute profile is required for provisioning new databases and cloning existing databases. The compute profile helps to ensure the availability and efficiency of the database server VMs and the databases within the Nutanix cluster.

質問 # 122
When the NDB upgrade includes updates to the out-of-the-box (OOB) software profiles, what happens to older OOB software profile versions when upgrading NDB?

A. If the database VMs using the software profiles are using Time Machines and have had a successful snapshot in the last 24 hours before the patch.
B. If the software profiles are not in use, NDB deletes all versions of the profiles from the metadata and protection domains.
C. If the database VMs are not using the base version of the software profile NDB deletes all versions of the profiles from the metadata and protection domains.
D. If the database VM using the software profiles are shutdown, NDB deletes all versions of the profiles from the metadata and protection domains.

正解：B

解説：
When upgrading NDB and the upgrade includes updates to out-of-the-box (OOB) software profiles (e.g., predefined profiles for database software like PostgreSQL, SQL Server, etc.), NDB manages older versions of these profiles based on their usage. If the older OOB software profiles are not actively in use by any database VMs, NDB automatically deletes all versions of those profiles from its metadata and associated protection domains during the upgrade process. This cleanup mechanism helps maintain a lean and efficient system by removing obsolete profiles that are no longer relevant or required.
* Option A is incorrect because the condition about Time Machines and snapshots in the last 24 hours is not a documented criterion for profile deletion during an NDB upgrade.
* Option B is correct as it reflects NDB's behavior of removing unused OOB software profiles during upgrades to optimize resource usage and metadata.
* Option C is incorrect because shutting down database VMs does not trigger automatic deletion of software profiles; the key factor is whether the profiles are in use.
* Option D is incorrect because the concept of a "base version" is not relevant here; deletion depends solely on whether the profiles are unused, not on versioning specifics.
This behavior ensures that only active and necessary profiles persist post-upgrade, streamlining administration.

質問 # 123
An administrator needs to capture the database transaction logs.
Which Time Machine operation does NDB use to satisfy this requirement?

A. Log Flush
B. Snapshots
C. Write-Ahead Logging
D. Log Catch-up

正解：D

解説：
To capture database transaction logs in NDB, the Log Catch-up operation within the Time Machine is used.
Log Catch-up retrieves and applies transaction logs (e.g., PostgreSQL WAL, SQL Server logs) to a snapshot, ensuring the database can be restored to a specific point in time. This operation bridges gaps between snapshots by incorporating log data, maintaining a continuous recovery chain.
Other options are incorrect:
* A. Write-Ahead Logging: A database feature (e.g., in PostgreSQL), not an NDB Time Machine operation.
* B. Log Flush: Refers to writing logs to disk, not capturing them for recovery.
* D. Snapshots: Capture the database state but do not handle transaction logs specifically.
Thus, the verified answer is C, aligning with NDB's log management.

質問 # 124
Era allows custom metadata to be assigned to entities (clones, time machines, databases, and database servers) by using which component?

A. Index
B. Tags
C. Text
D. Notes

正解：B

解説：
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.

質問 # 125
What is purpose of the NDB Database Agent service?

A. Schedules and monitors the NDB-related operations.
B. Hosts one or more source databases for the same time machine.
C. Temporarily stores the transaction logs.
D. Contains an instance of the database engine software.

正解：A

解説：
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.
