Full question →easymultiple choiceObjective-mapped
A company hosts a mission-critical customer portal on Azure virtual machines. To ensure continuous availability, they deploy the application across two separate Azure regions. If one region experiences a failure, traffic is automatically routed to the other region with minimal disruption. Which security goal is primarily being addressed by this architecture?
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
Confidentiality
Confidentiality focuses on restricting access to data to authorized users, often through encryption. Redundancy across regions does not directly address who can see the data.
B
Distractor review
Integrity
Integrity ensures data has not been altered by unauthorized parties. While failover mechanisms may preserve data integrity, the primary goal of multi-region deployment is to keep the service running, not to prevent modification.
C
Best answer
Availability
Correct. Availability ensures that resources are accessible to authorized users when needed. Deploying across multiple regions with automatic failover is a classic implementation of availability.
D
Distractor review
Non-repudiation
Non-repudiation prevents individuals from denying that they performed an action. This is typically achieved through audit logs or digital signatures, not through geographic redundancy.
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 SC-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Availability — The CIA triad consists of Confidentiality, Integrity, and Availability. This scenario describes redundancy and failover to maintain service continuity, which directly aligns with the security goal of Availability. Confidentiality ensures data is not accessible to unauthorized parties, typically via encryption. Integrity ensures data is not tampered with, often using hashes or checksums. Non-repudiation prevents denial of actions, usually through audit logs or digital signatures.
