DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
Exhibit
Refer to the exhibit.
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'MyStr0ngP@ssw0rd!';
CREATE DATABASE SCOPED CREDENTIAL SasCredential
WITH IDENTITY = 'SHARED ACCESS SIGNATURE',
SECRET = '?sv=2020-08-04&ss=b&srt=sco&sp=rl&se=2025-12-31T23:59:59Z&st=2025-01-01T00:00:00Z&spr=https&sig=...';
CREATE EXTERNAL DATA SOURCE MyDataSource WITH (
LOCATION = 'wasbs://mycontainer@mystorageaccount.blob.core.windows.net',
CREDENTIAL = SasCredential
);You are reviewing a script to create an external data source in Azure Synapse Analytics serverless SQL pool. Based on the exhibit, what is the purpose of the SAS token?
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
✓
To provide read access to the container for querying data.
The SAS token grants read and list permissions (sp=rl) to the container, which allows the serverless SQL pool to read data from the container. Option B is incorrect because the SAS token does not have write permission (sp=rl, no write). Option C is incorrect because the SAS token does not encrypt the connection; it provides delegated access. Option D is incorrect because the SAS token is used in the credential to access storage, not to authenticate to the serverless SQL pool.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
To provide read access to the container for querying data.
Why this is correct
The SAS includes 'sp=rl' which grants read and list permissions.
- ✗
To provide write access to the container for storing query results.
Why it's wrong here
The permissions are 'rl' (read and list), not write.
- ✗
To encrypt the connection between the serverless pool and storage.
Why it's wrong here
SAS is not used for encryption; HTTPS handles encryption.
- ✗
To authenticate the user to the serverless SQL pool.
Why it's wrong here
The credential is for storage access, not SQL pool authentication.
