NEW QUESTION # 289
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 # 290
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?
Answer: D
Explanation:
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.

NEW QUESTION # 291
Where are two locations an administrator would find the size of a Source Database? (Choose two.)
Answer: B,C
Explanation:
* Option A: On the Era Dashboard Database Summary Table under Source Database. The dashboard provides a summary of the databases, including their sizes1.
* Option B: Under the Capacity widget on the Database Server VMS > List database summary page.
While this might provide information about the capacity, it does not specifically provide the size of a Source Database.
* Option C: On the Databases > Sources table. This table provides detailed information about the databases, including their sizes1.
* Option D: On the Profiles > Database Parameters list for the assigned DB Parameter Profile. This list provides parameters for the database but does not provide the size of a Source Database.
NEW QUESTION # 292
When an Oracle database is upgraded using Era, what is the type of upgrade category?
Answer: B
Explanation:
When an Oracle database is upgraded using Era, the type of upgrade category is an "In-place upgrade". This method involves upgrading the database software within the same Oracle home as the existing database. The AutoUpgrade utility is used to automate the upgrade process, both before starting upgrades, during upgrade deployments, and during post-upgrade checks and configuration migration1. This method is preferred due to its simplicity and efficiency1.
NEW QUESTION # 293
When an administrator no longer wants to use a software profile version, what happens when it is deprecated?
Answer: C
Explanation:
In Nutanix Database Service (NDB), when an administrator deprecates a software profile version, it is marked as obsolete and restricted from certain operations. Specifically, a deprecated software profile version can no longer be used for provisioning new database instances or VMs. This ensures that only current, supported versions are utilized for new deployments, maintaining consistency and security. Existing database servers using the deprecated profile can continue to operate and may still be patched (if updates are compatible), but the profile itself is excluded from future provisioning tasks.
Option A is correct because deprecation explicitly prevents the profile version from being selected for new provisioning, aligning with NDB's lifecycle management.
Option B (It can be used in provisioning) is incorrect as this contradicts the purpose of deprecation.
Option C (Any database server using that profile will be updated to the latest software profile) is incorrect because deprecation does not automatically update existing servers; it only affects new provisioning.
Option D (Any database server using that software profile can no longer be patched) is incorrect because patching existing servers is still possible if compatible updates exist, independent of the profile's deprecated status.
Deprecation is a deliberate administrative action to phase out outdated profiles while preserving existing deployments.
