Which THREE security features are available in Azure Data Lake Storage Gen2 to protect data at rest and in transit? (Choose three.)
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
✓
Azure Storage firewalls and virtual network rules
Options A, C, and D are correct. Azure Storage firewalls and virtual network rules provide network-level security to restrict access. Encryption at rest using Storage Service Encryption (SSE) protects data at rest with AES-256 encryption. HTTPS ensures data in transit is encrypted. Option B (Azure Information Protection) is a classification and labeling service, not a built-in storage security feature. Option E (Azure Policy) is for governance and compliance, not direct data protection.

Symmetric Encryption Algorithm Comparison
| Algorithm | Key Size | Block Size | Status | Notes |
|---|---|---|---|---|
| AES-128 | 128-bit | 128-bit | Current standard | NIST approved; WPA3, TLS |
| AES-256 | 256-bit | 128-bit | Current standard | Preferred for sensitive / govt data |
| 3DES | 112-bit effective | 64-bit | Deprecated (2023) | Replaced by AES |
| DES | 56-bit | 64-bit | Broken | Cracked in < 24 h; never deploy |
| ChaCha20 | 256-bit | Stream cipher | Current | TLS 1.3, WireGuard |
