Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A multinational company is expanding its online retail business to new countries. The company needs to deploy its web application in Azure regions that are geographically close to customers in Europe, Asia, and North America to minimize latency. The IT team can deploy identical application instances in multiple regions within minutes using Azure Resource Manager templates. Which benefit of cloud computing does this scenario best illustrate?
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
High availability
High availability refers to keeping applications running despite component failures, usually through redundancy within a single region or across zones. The scenario is about deploying to multiple distant regions for latency reduction, not about maintaining uptime during failures.
B
Distractor review
Elasticity
Elasticity is the ability to scale computing resources up or down automatically based on demand. The scenario does not mention scaling in response to load changes; it focuses on deploying identical instances in different geographic locations.
C
Best answer
Global reach
Global reach (also called geographic distribution) is the cloud benefit that allows organizations to deploy applications and services in data centers around the world, reducing latency for users in different regions. The company is using this capability to serve customers in Europe, Asia, and North America with local instances.
D
Distractor review
Disaster recovery
Disaster recovery involves planning and infrastructure to recover from catastrophic failures, often by failing over to a secondary region. Although global deployment can support disaster recovery, the scenario's primary goal is minimizing latency for expanding business, not recovering from disasters.
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.

Question 1
A developer is building a serverless application that requires integration with an on-premises SQL Server database for real-time data processing. The on-premises network is connected to Azure via a site-to-site VPN. Which Azure service would allow the function to securely access the on-premises database without exposing it to the public internet?
Question 2
A solutions architect is designing a storage solution for a large media company. The company needs to store video files that are accessed infrequently but must be retained for several years for compliance. Which two Azure storage options meet these requirements? (Select two.)
Question 3
A company deploys a multi-tier application using Azure virtual machines. The web tier VMs must be evenly distributed across two distinct data centers within an Azure region to avoid a single point of failure from an infrastructure outage. Which Azure construct should they use to meet this requirement?
Question 4
A company wants to enforce a set of security policies across all their Azure subscriptions. They have created several individual policy definitions. Which Azure construct should they use to group these policies together and assign them as a single package?
Question 5
A company deploys a line-of-business application on an Azure virtual machine. The IT team wants to ensure the application remains secure. According to the shared responsibility model, which of the following security tasks is the sole responsibility of the customer (the company)?
Question 6
A company develops a web API that runs on Azure App Service. The development team wants to deploy a new version of the API to a staging environment, run integration tests against it, and then gradually shift production traffic to the new version. If any issues are detected, they want to immediately roll back to the previous version without redeploying. Which Azure App Service feature should the team use to meet these requirements?
FAQ
Questions learners often ask
What does this AZ-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: Global reach — This scenario demonstrates the global reach of cloud computing. Cloud providers like Microsoft Azure operate data centers in many regions around the world, enabling customers to deploy applications close to their users quickly and with minimal effort. This geographic distribution reduces latency and improves the user experience. The other options describe different benefits: high availability focuses on ensuring uptime through redundancy within a region, elasticity refers to automatically scaling resources based on demand, and disaster recovery involves recovering from failures, often by failing over to another region. While global reach can support disaster recovery, the primary advantage shown here is the ability to provision resources in multiple distant locations on demand.
