Show Answer
Correct Answer: the cool access tier of Azure Blob Storage
Explanation: Azure Blob Storage cool access tier has a minimum storage duration of 30 days. Deleting or moving data before 30 days incurs an early deletion fee, unlike the hot tier, Azure SQL Database, or Azure Cosmos DB.
Question 7
DRAG DROP
-
Match the authentication method to the appropriate level of security.
To answer, drag the appropriate authentication method from the column on the left to its level of security on the right.
NOTE: Each correct match is worth one point.
Explanation: Password authentication is easy to use but offers the weakest security. MFA increases security by requiring multiple factors but adds user friction, making it less convenient. Passwordless authentication (biometrics, FIDO2, passkeys) removes passwords, providing strong security with high user convenience.
Question 8
How many data copies are stored in gee-zone-redundant storage (GZRS)?
A. 2
B. 3
C. 6
D. 12
Show Answer
Correct Answer: C
Explanation: Geo-zone-redundant storage (GZRS) keeps six copies of data in total: three copies synchronously replicated across availability zones within the primary region, and three additional copies asynchronously replicated to a secondary region for geo-redundancy. This provides both zone-level and regional fault tolerance.
