NEW QUESTION # 134
When using the Patch OS now feature in NDB, how would an administrator limit the updates to security updates only for Red Hat-based operating systems?
Answer: C
Explanation:
When using the "Patch OS now" feature in NDB to apply updates to a Red Hat-based operating system, the administrator can limit updates to security patches only by leveraging the Advanced Options. Under the
"Custom commands" section of the operating system patching command window, entering yum update -- security instructs the package manager to install only security-related updates. This ensures the system remains secure without applying all available updates, which could introduce instability.
Other options are incorrect or incomplete:
* A. Point the database VM to a custom patch repository and enter yum update --security command This requires manual intervention outside NDB's patching framework.
* B. Check Advanced Options and under Pre-post commands, enter yum update security in the pre- operating system patching command window: Pre-post commands are for pre/post actions, not the main patching process, and the syntax lacks the --security flag.
* C. Point the database VM to a custom patch repository before using the Patch OS now feature:
This sets up a repository but doesn't specify security-only updates within NDB's interface.
Thus, the verified answer is D, aligning with NDB's patching customization.

NEW QUESTION # 135
How would an administrator enter the NDB command line to change the static IP address on the NDB VM?
Answer: D
Explanation:
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:

NEW QUESTION # 136
A new administrator is tasked with changing the NDB GUI password via CLl.
Which command will accomplish this task?
Answer: A
Explanation:
To change the NDB GUI password via the CLI, the administrator should use the command era-server > security password reset. This command interacts with the NDB server (referred to as era-server in the CLI context) to reset the password for the GUI admin user. The process typically prompts for the new password and confirmation, ensuring secure password management. This is the supported method for CLI-based password changes in NDB.
Other options are incorrect:
A). sudo passwd era: The passwd command is for Linux user accounts, not NDB-specific GUI credentials.
B). sudo user name admin password: This is not a valid command syntax for NDB CLI.
C). era-server > username admin password: This lacks the correct subcommand (security password reset) and syntax.
Thus, the verified answer is D, aligning with NDB's CLI security management.

NEW QUESTION # 137
An administrator needs to protect a database with a Point In Time Recovery (PITR) SLA that provides a minimum of seven days of log recovery.
What is the minimum Default SLA that meets this requirement?
Answer: C
Explanation:
Nutanix Era (NDB) utilizes DEFAULT_008 SLAs with varying frequencies for snapshots and log backups to achieve different recovery point objectives (RPOs). Here's how they compare:
* DEFAULT_008 GOLD SLA: Typically has frequent log backups (e.g., every 15 minutes) and snapshots every few hours. This is designed for critical databases with very low RPOs.
* DEFAULT_008 SILVER SLA: Offers a balance between protection and resource usage. Log backups might occur every hour with snapshots less frequently. This SLA is often suitable for databases requiring a good RPO without being overly resource-intensive.
* DEFAULT_008 BRONZE SLA: Has less frequent log backups (e.g., every few hours) and less frequent snapshots. This is used for databases with less stringent RPO requirements.
* DEFAULT_008 BRASS SLA: This has infrequent log backups and is usually considered the least protective SLA with the longest potential RPO Reasoning:
Since the requirement is to have at least a 7-day log recovery period, any SLA with more frequent log backups than daily is excessive. The DEFAULT_008 SILVER SLA, with its hourly log backups, easily satisfies this requirement, offering the ability to restore to a point in time within the last hour of the past seven days.

NEW QUESTION # 138
What is the first step to install NDB on a Nutanix AHV cluster?
Answer: A
Explanation:
To install NDB on a Nutanix AHV cluster, you need to download the QCOW2 image file of NDB from the Nutanix Support Portal and upload it to Prism Element. This image file contains the NDB software and the CentOS operating system. After uploading the image, you need to create a VM from the image and configure the network settings. Then, you need to register the NDB VM with Prism Central and enable the NDB service in the settings menu. References: Nutanix Support & Insights, Professional Services: NDB Database Cloning
