Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company stores contract PDFs in Azure Blob Storage. The application must keep working if one datacenter in the primary region has an outage, and auditors also want read-only access to the replicated data from the secondary region during a regional outage. Which redundancy option should the administrator choose?
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
LRS
LRS keeps multiple copies only within one datacenter or availability domain and does not provide geographic replication.
B
Distractor review
ZRS
ZRS protects against a single zone failure, but it does not provide a readable secondary region.
C
Distractor review
GZRS
GZRS adds geo-replication and zone redundancy, but the secondary region is not readable during normal operations.
D
Best answer
RA-GZRS
RA-GZRS combines zone redundancy in the primary region with geo-replication and read access to the secondary endpoint.
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 route table contains these entries: 10.0.0.0/8 with next hop Virtual appliance, and 10.1.1.0/24 with next hop Virtual network gateway. Which next hop will Azure use for traffic to 10.1.1.5?
Question 2
You are deploying a stateless web application on Azure virtual machines. The solution must automatically add and remove instances based on CPU demand and allow all instances to be managed as one logical group. Which Azure compute feature should you deploy?
Question 3
You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.
Question 4
You need to deploy several identical virtual machines and ensure that the failure of a single Azure host does not affect all of them. Which feature should you use?
Question 5
You need to connect VNet-Hub and VNet-Spoke so that resources in both virtual networks can communicate privately over the Microsoft backbone. Both virtual networks are in the same region. What should you configure?
Question 6
You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?
FAQ
Questions learners often ask
What does this AZ-104 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: RA-GZRS — RA-GZRS is the best fit because the workload needs both resilience to a zonal failure in the primary region and read access from the secondary region if a broader outage occurs. Zone-redundant storage helps keep the account available when a single datacenter or zone is affected, while the read-access feature supports disaster recovery validation or audit reads without waiting for a failover event. That combination is stronger than standard geo-redundant options and avoids the availability gap of non-zone-redundant designs. Why others are wrong: LRS is limited to one location and is the weakest resiliency choice here. ZRS handles a zone failure but provides no geo-replication. GZRS does provide both zone and geo protection, but the secondary replica is not readable until failover, which does not meet the auditor requirement.
