AZ-204 Practice Question: Connect to and consume Azure services and third-party services
Your company uses Azure Blob Storage to store sensitive documents. You need to ensure that all access to the storage account is encrypted in transit and that clients must use TLS 1.2 or higher. Which configuration should you enforce?
⚠ Common exam trap
Watch out — candidates often confuse 'Secure transfer required' (which only enforces HTTPS) with the 'Minimum TLS version' setting, mistakenly believing that enabling HTTPS alone guarantees a specific TLS version, when in fact HTTPS can be negotiated over TLS 1.0, 1.1, or 1.2 unless explicitly restricted.
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
✓
Set the 'Minimum TLS version' to 1.2 in the storage account's configuration.
Setting the 'Minimum TLS version' to 1.2 in the storage account's configuration explicitly enforces that all client connections must use TLS 1.2 or higher, rejecting any requests using older, less secure TLS versions. This directly addresses the requirement to ensure encryption in transit with a specific minimum TLS version, as Azure Blob Storage supports TLS 1.0, 1.1, and 1.2 by default, and this setting overrides that default to enforce the higher standard.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a private endpoint for the storage account.
Why it's wrong here
Using a private endpoint for the storage account establishes a secure, private connection from your virtual network to Azure Storage, bypassing the public internet entirely. While this significantly enhances network security by restricting access to a private IP address within your VNet, it does not directly enforce the specific version of the Transport Layer Security (TLS) protocol used for the encrypted communication channel. The TLS version is a protocol-level setting, independent of the network path.
- ✓
Set the 'Minimum TLS version' to 1.2 in the storage account's configuration.
Why this is correct
Setting the 'Minimum TLS version' to 1.2 in the storage account's configuration directly addresses the requirement to enforce a specific encryption standard. This configuration ensures that Azure Storage will reject any connection attempts that utilize older, less secure TLS versions (such as TLS 1.0 or TLS 1.1). Consequently, all data in transit to and from the storage account will be encrypted using the more robust and secure TLS 1.2 or later protocols, meeting compliance and security best practices.
- ✗
Configure network rules to allow only from trusted IPs.
Why it's wrong here
Configuring network rules, such as IP firewalls or virtual network rules, allows you to restrict access to the storage account to only specified IP addresses or subnets. While this is a critical security measure for controlling who can connect to the storage account at the network layer, it does not dictate the encryption protocol (TLS version) used once an allowed connection is established. An authorized connection could still potentially use an older, less secure TLS version if not explicitly enforced elsewhere.
- ✗
Enable 'Secure transfer required' (HTTPS only).
Why it's wrong here
Enabling 'Secure transfer required' ensures that all requests to the storage account must be made over HTTPS, preventing unencrypted HTTP connections. While HTTPS inherently uses TLS for encryption, this setting alone does not specify which version of TLS must be used. Without further configuration, older and less secure TLS versions (e.g., TLS 1.0 or 1.1) could still be negotiated as part of the HTTPS handshake, failing to meet a specific minimum TLS version requirement.
Quick reference
Azure Blob Storage Tier Comparison
| Tier | Storage Cost | Retrieval Cost | Latency | Use Case |
|---|---|---|---|---|
| Hot | Highest | Lowest | Immediate | Active data, frequent reads |
| Cool | Lower | Higher | Immediate | Data accessed < once / month |
| Cold | Lower still | Higher | Immediate | Data accessed < once / quarter |
| Archive | Lowest | Highest + rehydration delay | Hours | Long-term compliance retention |
