Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A company runs a mission-critical application on Azure virtual machines (VMs) in the West US region. The application consists of multiple VMs that must be recovered in a specific order during a disaster: database VM first, then application VMs, then web VMs. They also require that after failover to East US, the VMs retain their private IP addresses to avoid DNS updates. The recovery point objective (RPO) is 5 minutes and recovery time objective (RTO) is 30 minutes. The company needs to perform quarterly disaster recovery tests without impacting production. Which combination of Azure Site Recovery features should they configure?
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
Distractor review
Use crash-consistent replication, recovery plans with manual ordering, and target network with same IP address range
Crash-consistent replication may not provide the 5-minute RPO for database consistency, and manual ordering is not reliable for automated DR.
B
Best answer
Use app-consistent replication, recovery plans with pre/post scripts for ordering, and static IP address assignment in failover settings
App-consistent replication ensures data integrity. Recovery plans with scripts automate the ordering. Static IP assignment retains private IPs.
C
Distractor review
Use multi-VM consistency groups, recovery plans with automation runbooks, and Azure Traffic Manager to redirect traffic
Multi-VM consistency groups help with cross-VM consistency but do not handle IP retention. Traffic Manager is for DNS-based traffic routing, not IP retention.
D
Distractor review
Use application-consistent replication, recovery plans with pre/post scripts for ordering, and target network with different IP address range and DNS updates
Using a different IP address range would require DNS updates and break the requirement to retain IP addresses.
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: Use app-consistent replication, recovery plans with pre/post scripts for ordering, and static IP address assignment in failover settings — Azure Site Recovery can achieve a 5-minute RPO using app-consistent replication. Recovery plans allow ordering of VMs in groups and can run pre/post scripts to orchestrate custom actions. To retain private IPs, the target network should be configured with the same address space and static IP assignment for the replicas. This combination meets all requirements.
