A multinational corporation classifies its data into three tiers: Tier 1 (customer transactions, RPO 5 minutes, RTO 1 hour), Tier 2 (internal collaboration documents, RPO 24 hours, RTO 8 hours), and Tier 3 (marketing archives, RPO 7 days, RTO 48 hours). The company is designing its recovery strategy and must balance cost. Which approach aligns with tiered recovery principles?

Apply synchronous replication to all three tiers to ensure maximum protection

Use synchronous replication for Tier 1, daily backups for Tier 2, and weekly backups for Tier 3

Use daily backups for all tiers and accept the 24-hour RPO for Tier 1

Use weekly backups for all tiers to minimize storage costs

A healthcare provider uses asynchronous replication to a secondary site for its patient records database. The RPO is 15 minutes. During a regional outage, the primary site is lost, and the secondary site is activated. The database administrator discovers that the last 10 minutes of transactions are missing. The provider's compliance team reports that the RPO was violated. What is the most likely reason for this violation?

The database was restored from a full backup instead of the replicated copy

The secondary site was a warm site, not a hot site

The RPO was set too low for asynchronous replication

The replication lag exceeded the 15-minute RPO at the time of the outage

What is a common challenge when using cloud-based recovery?

Dependence on internet bandwidth for data transfer and recovery

Requirement to purchase dedicated hardware

Inability to store data offsite

Lack of encryption for data at rest

A company's backup strategy uses a full backup every Sunday and incremental backups on other days. The company's RPO is 24 hours, and the RTO is 12 hours. The backup administrator is considering switching to differential backups to simplify recovery. Which trade-off should the administrator consider?

Differential backups provide a better RPO than incremental backups.

Differential backups have no impact on storage or recovery time.

Differential backups require less storage than incremental backups but increase recovery time.

Differential backups require more storage than incremental backups but reduce recovery time because only the last differential backup is needed.

A startup with no on-premises infrastructure wants to implement a disaster recovery solution for its cloud-based application. The application runs in a single Azure region, and the startup needs to recover within 4 hours (RTO) with no more than 1 hour of data loss (RPO). The startup has a limited budget and wants to minimize ongoing costs. Which cloud-based recovery approach best meets these requirements?

Use Azure Site Recovery to replicate the application to a secondary Azure region

Perform nightly backups to Azure Blob Storage and restore to a new environment on failure

Use Azure Backup with daily snapshots and no secondary region

Deploy a full standby environment in a secondary region that is always running
