Question 2

Which Azure Backup retention tier stores recovery points at a lower cost for long-term archive?

Accepted Answer

Archive tier

Answer

The Archive tier in Azure Backup stores recovery points cheaply for long-term retention (e.g., compliance requirements of 7+ years) at significantly lower cost than the vault-standard tier.

Question 3

A company needs automatic DNS-based failover from a primary Azure region to a secondary region when the primary becomes unhealthy. Which Azure service provides this?

Accepted Answer

Azure Traffic Manager with Priority routing

Answer

Azure Traffic Manager with Priority routing monitors endpoint health via DNS and automatically redirects traffic to the secondary endpoint when the primary endpoint fails health checks.

Question 4

What does the Recovery Time Objective (RTO) define in a business continuity plan?

Accepted Answer

The maximum time allowed to restore business operations after a disaster

Answer

RTO is the maximum tolerable duration of a service outage — it defines how quickly systems must be restored to avoid unacceptable business impact.

Question 5

You configure Azure Site Recovery for a VM and initiate a planned failover to the secondary region. What happens to replication after the failover?

Accepted Answer

Replication automatically reverses to replicate from the new primary back to the original region

Answer

After a planned failover completes, Azure Site Recovery automatically sets up reverse replication so the new primary (secondary region) now replicates back to the original region, maintaining DR protection.
