- A
Generate shared access signatures (SAS) with specific permissions and expiry times.
SAS tokens provide granular, time-limited access to specific blobs.
- B
Enable Azure Active Directory authentication for the storage account.
Why wrong: Azure AD authentication is not time-limited by default and requires the partner to have Azure AD.
- C
Configure a firewall on the storage account to allow only partner IP addresses.
Why wrong: Firewall restricts network, not access control to blobs.
- D
Use Azure RBAC to assign the Storage Blob Data Reader role to partner users.
Why wrong: RBAC is at container level, not granular to blob, and cannot expire automatically.
- E
Use Azure Storage Service Encryption with customer-managed keys in Azure Key Vault.
Provides encryption at rest with CMK.
Quick Answer
The answer is to combine Azure Storage Service Encryption with customer-managed keys in Azure Key Vault and Shared Access Signatures (SAS). This pairing directly meets all requirements because customer-managed keys (CMK) enforce encryption at rest with keys you control, while SAS tokens provide granular, time-limited access to specific blobs without exposing the storage account key. On the Microsoft Cybersecurity Architect exam, this scenario tests your ability to distinguish between access control mechanisms: RBAC operates at the container level and lacks automatic expiration, whereas SAS offers precise blob-level permissions with built-in expiry. A common trap is selecting Azure AD authentication, which is not time-limited by default and requires additional conditional access policies. Remember the memory tip: “CMK locks the data, SAS unlocks the door—just for a moment.”
SC-100 Practice Question: Design security solutions for applications and data
This SC-100 practice question tests your understanding of design security solutions for applications and data. 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.
A company is designing a secure data sharing solution with a partner organization. The data will be stored in Azure Blob Storage. Requirements include: encryption at rest with customer-managed keys, granular access control to specific blobs, and the ability to expire access automatically. Which TWO solutions should you combine? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Generate shared access signatures (SAS) with specific permissions and expiry times.
Azure Storage Service Encryption with customer-managed keys (CMK) provides encryption at rest. Shared access signatures (SAS) provide granular, time-limited access to specific blobs. RBAC is less granular (container level). Azure AD authentication is not time-limited by default. Option A and C together meet all requirements.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.
