A) RTO measures data loss, while RPO measures downtime B) RTO measures downtime, while RPO measures data loss C) RTO and RPO are identical D) RTO measures network latency, while RPO measures storage capacity Answer: B) RTO measures downtime, while RPO measures data loss Explanation: RTO (Recovery Time Objective) specifies the maximum allowable downtime before operations must be restored, whereas RPO (Recovery Point Objective) specifies the maximum acceptable data loss in case of an incident.
To achieve a lower RPO, what should be adjusted in the backup strategy? A) Increase the backup window B) Decrease the backup frequency C) Increase the backup frequency D) Decrease the backup retention period Answer: C) Increase the backup frequency Explanation: A lower RPO means less data loss is acceptable, which requires more frequent backups to ensure that the backup points are closer to the current state.

What role do Access Controls play in a Cohesity protection policy?

Explanation: Application-consistent backups ensure that all in-memory data is written to disk, providing a consistent state of the application data, which is crucial for applications like databases.

Why might crash-consistent backups be insufficient for certain applications? A) They take longer to complete B) They do not capture application-specific data states C) They require additional storage D) They are not supported by Cohesity Answer: B) They do not capture application-specific data states Explanation: Crash-consistent backups may not capture the exact state of application data, leading to potential data corruption or inconsistencies upon restoration, especially for databases and transactional applications.
Which of the following scenarios is best suited for using crash-consistent backups? A) Critical financial databases B) Virtual machines running non-critical applications C) Email servers D) Active directory services Answer: B) Virtual machines running non-critical applications Explanation: Crash-consistent backups are suitable for non-critical applications where data consistency is not as crucial, and minor data loss or inconsistencies are acceptable. 24 What additional steps are typically involved in creating an application-consistent backup compared to a crash-consistent backup? A) No additional steps are involved B) Shutting down the application C) Quiescing the application to ensure data consistency D) Encrypting the backup data Answer: C) Quiescing the application to ensure data consistency Explanation: Creating an application-consistent backup usually involves quiescing the application, which pauses operations to ensure that all data is written and consistent before the backup is taken.
In Cohesity, which feature helps in creating application-consistent backups for Microsoft Exchange?

A) VSS Integration B) Snapshot Scheduler C) Data Deduplication D) Instant Mass Restore Answer: A) VSS Integration Explanation: Volume Shadow Copy Service (VSS) integration allows Cohesity to create application- consistent snapshots by coordinating with Microsoft Exchange to ensure data consistency during backups.

Which type of backup is typically faster to perform, application-consistent or crash- consistent? A) Application-consistent backups are faster B) Crash-consistent backups are faster C) Both take the same amount of time D) It depends on the application Answer: B) Crash-consistent backups are faster Explanation: Crash-consistent backups are generally faster because they do not require the additional steps of quiescing applications and ensuring data consistency, unlike application-consistent backups.
Which of the following best describes a crash-consistent snapshot? A) A snapshot taken after gracefully shutting down all applications B) A snapshot that includes transaction logs C) A snapshot that captures the exact state of the disk at a specific point in time without coordinating with applications D) A snapshot that only includes system files Answer: C) A snapshot that captures the exact state of the disk at a specific point in time without coordinating with applications Explanation: A crash-consistent snapshot is akin to the state of the system right after a crash, where the disk's state is captured without any coordination with running applications, potentially leading to inconsistent application data.
