Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company runs a critical web application on Azure VMs in the West US region. They need a disaster recovery solution that replicates the VMs to the East US region. The recovery point objective (RPO) must be 30 minutes, and the recovery time objective (RTO) must be 1 hour. The company also needs to perform quarterly disaster recovery drills without impacting the production environment. Additionally, after a failover, the solution must automatically update traffic management to route users to the East US region. Which combination of Azure services should they use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Azure Site Recovery and Azure Traffic Manager
Azure Site Recovery handles VM replication with the required RPO/RTO and supports non-disruptive test failovers. Azure Traffic Manager can automatically route user traffic to the secondary region after failover by using endpoint monitoring and failover priority.
B
Distractor review
Azure Backup and Azure Traffic Manager
Azure Backup provides backup and restore but does not meet the RPO/RTO for replication and does not support automated failover or test failovers.
C
Distractor review
Azure Site Recovery and Azure Front Door
Azure Front Door is a global load balancer with advanced routing features, but Azure Traffic Manager is more commonly used for regional failover with Site Recovery. Front Door also works but Traffic Manager is the simpler choice for this scenario.
D
Distractor review
Azure Backup and Azure Front Door
Azure Backup does not provide the required replication capabilities, and Azure Front Door alone cannot replicate VMs.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Azure Site Recovery and Azure Traffic Manager — Azure Site Recovery provides VM replication to a secondary region with support for test failovers that do not affect production. Azure Traffic Manager can be used to distribute traffic across regions and can be configured to automatically redirect traffic to the secondary region upon failover. Azure Backup is for backup and restore, not for replication with RPO/RTO requirements. Azure Front Door is a global load balancer with SSL offload and WAF but does not provide VM replication.
