Nutanix Exam NCP-DB Topic 6 Question 21 Discussion

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.
