A company classifies its data into three tiers: Tier 1 (mission-critical, RPO 15 minutes, RTO 1 hour), Tier 2 (important, RPO 4 hours, RTO 8 hours), and Tier 3 (non-critical, RPO 24 hours, RTO 48 hours). Which recovery strategy aligns with this tiered approach?

Tier 1: synchronous replication to a hot site; Tier 2: hourly backups to a warm site; Tier 3: daily backups to a cold site

Tier 1: asynchronous replication to a warm site; Tier 2: daily backups; Tier 3: monthly backups

Tier 1: daily backups to a cold site; Tier 2: weekly backups; Tier 3: no backups

Use the same backup schedule and recovery site for all tiers

What does a storage snapshot capture?

A backup of data to an offsite location

A point-in-time state of a storage volume or file system

A continuous real-time copy of all data changes

A full copy of all data stored on a separate medium

A financial institution has a critical trading application with an RTO of 15 minutes and an RPO of zero. The institution is evaluating disaster recovery site options. Which site option and replication strategy combination best meets these requirements?

Warm site with asynchronous replication

Hot site with asynchronous replication

Hot site with synchronous replication

What is the primary purpose of a data recovery strategy within a disaster recovery plan?

To prevent any data loss from occurring during a disaster

To ensure that all data is backed up continuously to a single offsite location

To define the procedures and technologies used to restore data and systems to a usable state after a disruption

To eliminate the need for backup storage by using real-time data mirroring exclusively

How does data criticality influence the selection of a recovery strategy?

Lower criticality data requires more frequent backups

Higher criticality data requires more stringent recovery objectives, such as lower RPO and RTO

Criticality only affects storage location, not recovery strategy

All data types should use the same recovery strategy regardless of criticality
