The correct combination is Azure Disk Encryption and HTTPS. Azure Disk Encryption secures data at rest by leveraging BitLocker on Windows or DM-Crypt on Linux to encrypt the VM’s managed disks, while HTTPS encrypts data in transit between the client and the application, ensuring end-to-end protection. On the AZ-500 exam, this question tests your ability to distinguish between encryption layers: Azure Disk Encryption is the only native VM-level at-rest solution, whereas Storage Service Encryption only covers Azure Storage blobs, not the VM’s OS or data disks. A common trap is confusing SSL with HTTPS—SSL is the older protocol, but HTTPS is the standard for transit encryption in Azure. For a quick memory tip, think “Disk for disk, HTTPS for hop”—Azure Disk Encryption locks the disk data, and HTTPS secures every network hop.
AZ-500 Secure compute, storage, and databases Practice Question
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are deploying a new application on Azure VMs. The application must be encrypted at rest and during transmission. Which combination of features should you implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Disk Encryption and HTTPS
Option C is correct because Azure Disk Encryption provides at-rest encryption for managed disks using BitLocker or DM-Crypt, while HTTPS ensures encryption in transit. Option A is wrong because Azure Storage Service Encryption only encrypts data in Azure Storage, not on VMs. Option B is wrong because SSL is for transit but Azure Disk Encryption is for at-rest. Option D is wrong because Azure Firewall provides network security, not encryption.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure Firewall and Azure Disk Encryption
Why it's wrong here
Firewall provides network security, not transit encryption.
✓
Azure Disk Encryption and HTTPS
Why this is correct
Disk Encryption secures data at rest; HTTPS secures data in transit.
Related concept
Static NAT maps one inside address to one outside address.
✗
Azure Storage Service Encryption and SSL
Why it's wrong here
Storage Service Encryption does not encrypt VM disks.
✗
Azure Disk Encryption and SSL
Why it's wrong here
SSL is a protocol, but HTTPS is more appropriate for web traffic; however, the combination is incomplete.
Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
