질문 # 118
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?
정답：C
설명：
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.

질문 # 119
An administrator has been tasked with OS and database patching in a Nutanix NDB environment. The administrator wishes to automate these activities.
What should the administrator configure to accomplish this task?
정답：D
설명：
To automate OS and database patching in a Nutanix NDB environment, the administrator should configure a Maintenance Window. A Maintenance Window in NDB allows the administrator to schedule automated patching tasks (e.g., OS updates and database software updates) during specified time periods, minimizing disruption to production workloads. This feature integrates with software profiles and can be set to run periodically or on-demand, ensuring patches are applied efficiently and consistently across the environment.
* Option A (Access Control) is incorrect because Access Control manages user permissions, not automation of patching.
* Option B (Pulse) is incorrect because Pulse is a monitoring tool, not a scheduling mechanism for patching.
* Option C (Maintenance Window) is correct as it provides the scheduling and automation framework for patching activities.
* Option D (SMTP Server) is incorrect because SMTP is for email notifications, not patching automation.
This configuration enhances operational efficiency and reliability.

질문 # 120
An administrator needs to enable multi-cluster to setup NDB HA.
What should the administrator configure for the NDB Agent to satisfy this requirement?
정답：B
설명：
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.

질문 # 121
An administrator wants to provision a MySQL HA database with a default schema for the development team.
Which option should the administrator choose in NDB?
정답：B
설명：
During MySQL HA provisioning, NDB creates the database or schema identified by the Database Name supplied in the provisioning workflow. In MySQL terminology, CREATE DATABASE and CREATE SCHEMA are equivalent, so using the intended default schema as the database name gives developers the required schema as part of the managed deployment. A post-create script could create additional objects, but it is unnecessary for the initial default schema and adds avoidable custom automation. The provisioning workflow does not require uploading a SQL file, and a software profile packages database software and operating-system binaries rather than application schemas. Therefore, the default schema should be defined as the database name. This keeps schema creation within NDB's declarative provisioning workflow and makes the resulting database manageable as part of the MySQL HA instance. Nutanix uses the Database Name field for this purpose.
질문 # 122
An administrator needs to create a custom PostgreSQL HA software profile.
Which software component manages the state of the cluster and handles failover?
정답：D
설명：
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.
