質問 # 72
Which policies define Time Machine data availability across multiple registered clusters in NDB?

A. Recovery Plans
B. Data Access Management
C. Service Level Agreements
D. Data Protection

正解：A

解説：
The recovery plans policy defines the Time Machine data availability across multiple registered clusters in NDB. The recovery plans policy allows the database administrator to specify the source and target clusters, the frequency and retention of the cross-cluster snapshots, and the network and compute profiles for the recovery operations. The recovery plans policy helps to ensure the disaster recovery and business continuity of the NDB-managed databases in case of a cluster failure or outage.
The data access management policy defines the access permissions and roles for the NDB users and groups.
The data access management policy allows the database administrator to grant or revoke access to the NDB instance, the database server VMs, the databases, and the database operations. The data access management policy helps to ensure the security and compliance of the NDB-managed databases and users.
The data protection policy defines the backup and restore settings for the NDB-managed databases. The data protection policy allows the database administrator to specify the frequency, retention, and compression of the database snapshots, and the backup location and encryption for the database backups. The data protection policy helps to ensure the backup and recovery of the NDB-managed databases within the same cluster.
The service level agreements policy defines the performance and availability metrics for the NDB-managed databases. The service level agreements policy allows the database administrator to monitor and enforce the database uptime, latency, throughput, and IOPS. The service level agreements policy helps to ensure the quality of service and performance of the NDB-managed databases.

質問 # 73
An administrator needs to create a custom PostgreSQL HA software profile.
Which software component manages the state of the cluster and handles failover?

A. keepa lived
B. etcd
C. HAProxy
D. Patroni

正解：D

解説：
NDB supports PostgreSQL HA software profiles for provisioning PostgreSQL databases with high availability. PostgreSQL HA software profiles consist of three components: etcd, HAProxy, and Patroni.
etcd is a distributed key-value store that provides a reliable way to store configuration data across a cluster of machines. etcd is used by Patroni to store and synchronize the cluster state and configuration.
HAProxy is a load balancer that distributes incoming requests to the PostgreSQL nodes. HAProxy is used to expose a single endpoint for database connections even as the roles of the individual nodes change.
Patroni is a template for PostgreSQL high availability. Patroni is responsible for managing the state of the cluster and handling failover. Patroni uses etcd as the distributed configuration store and relies on HAProxy for load balancing.
Therefore, the software component that manages the state of the cluster and handles failover is Patroni.

質問 # 74
An administrator needs to provision a PostgreSQL cluster instance with an external Load Balancer. Which software can be omitted on the Reference VM while creating the Software Profile?

A. HAProxy
B. etcd
C. keepalived
D. Patron

正解：A

解説：
When provisioning a PostgreSQL cluster instance with an external load balancer in NDB, the administrator creates a software profile from a reference VM. The reference VM typically includes software like Patroni (for HA management), HAProxy (for internal load balancing), keepalived (for high availability IP management), and etcd (for distributed configuration). Since an external load balancer is used, the internal HAProxy can be omitted from the reference VM. NDB will rely on the external load balancer to distribute traffic, eliminating the need for HAProxy in the software profile, while the other components remain essential for cluster management.
* Option A (Patroni) is incorrect because Patroni is required for PostgreSQL HA management.
* Option B (HAProxy) is correct as it can be omitted when an external load balancer is configured.
* Option C (keepalived) is incorrect because keepalived is needed for HA IP failover.
* Option D (etcd) is incorrect because etcd is necessary for distributed configuration in the cluster.
This adjustment streamlines the profile for external load balancer use.

質問 # 75
An administrator is tasked with auditing NDB SLAs. What data will the administrator be reviewing?

A. Clone Management
B. Snapshot schedules
C. Data retention policies
D. Recovery Time Objective

正解：C

質問 # 76
Which port should be opened to ensure the NDB server, NDB agent, and NDB database agent can communicate with the registered cluster via REST API calls?

A. 0
B. 1
C. 2
D. 3

正解：D

解説：
To ensure the NDB server, NDB agent, and NDB database agent can communicate with the registered cluster via REST API calls, port 2009 must be opened. This port is used by NDB components to facilitate RESTful communication with the Nutanix cluster (e.g., Prism Element or Prism Central) for operations such as provisioning, monitoring, and management. Proper firewall configuration to allow traffic on this port is a prerequisite for NDB's integration with the cluster.
Other options are incorrect:
B). 3205: Not a standard NDB port; used for other Nutanix services.
C). 3260: Associated with iSCSI, not REST API communication.
D). 9440: Used for Prism Element's HTTPS management interface, not NDB-specific REST calls.
Thus, the verified answer is A, reflecting NDB's REST API requirements.
