COH-285 Exam Dumps - Cohesity Protection Professional Questions and Answers

The correct action is to move E02003 to the scratch_pool. Cohesity NetBackup documentation states that the Policy volume pool specifies the default media pool for policy backups, and whenever a new volume is required, NetBackup allocates it from that indicated pool. It also identifies the scratch volume pool as the mechanism that lets NetBackup automatically transfer volumes when another pool has no media available. In the output, the policy requires server_tapes, but that pool has no usable available HCART2 media: E02007 and E02008 are active with retention levels 1 and 3, E02005 is full, E02006 is frozen, and E02004 is FULL/FROZEN. Unfreezing E02004 would not solve the issue because it remains full. NetBackup also stores tape backups with other backups at the same retention level by default, so this retention-level mismatch matters for active tapes. E02003 is the only unassigned, available HCART2 backup tape. Placing it in the scratch pool allows NetBackup to move it automatically into server_tapes when the job requests new media.

The default summary interval is 24 hours. In NetBackup Appliance AutoSupport/Call Home behavior, when Call Home is enabled and a monitored hardware or software failure occurs, the appliance uploads diagnostic and monitoring information to the AutoSupport server and also generates email notifications to the configured recipient list. The official Appliance AutoSupport Reference Guide describes three email notification types: an initial error notification when the failure is detected, a resolved notification when the failure clears, and “a 24-hour summary by email” for unresolved errors. The NetBackup Appliance Security Guide states the same operational sequence: the appliance sends an error email, a resolved email, and a 24-hour summary of currently unresolved errors. Therefore, 15 minutes, 1 hour, and 12 hours are not the documented default intervals for unresolved-error summary notification. Those values may resemble polling or alerting intervals in other monitoring systems, but NetBackup Appliance Call Home uses the daily summary model to reduce repeated notifications while keeping administrators informed of unresolved conditions. Reference topics: Appliance AutoSupport Reference Guide – About Call Home, Settings > Notification > Alert Configuration, and NetBackup Appliance Security Guide – Call Home alert behavior.

The replication job starts when the force interval for small replication jobs is reached. NetBackup SLP settings control how Storage Lifecycle Policy jobs are maintained and executed for the selected primary server. Cohesity documentation identifies these as SLP settings used to customize how SLP jobs run. For AIR replication batching, the controlling parameter here is SLP.MIN_SIZE_PER_REPLICATION_JOB. Official NetBackup documentation defines it as the smallest batch size that can run as a single replication job and states that the job does not run until enough images accumulate to reach that size, or until the force interval for small replication jobs is reached.

In this scenario, three backups of 5GB each create only 15GB of eligible replication data. That is below the configured 20GB threshold, so NetBackup does not start the replication job based on size. Because the backup window has closed and no additional backup images will arrive, the batch cannot reach 20GB. NetBackup therefore submits the small replication batch when the oldest image reaches the configured 60-minute force interval. The force interval is specifically designed to prevent NetBackup from waiting too long before submitting a small replication job. (veritas.com)
