AZ-900 Azure Storage Services 2 — Questions and Answers
Question 1: Which Azure Storage redundancy option keeps three copies of data within a single physical location in the primary region?
- Locally redundant storage (LRS) (Correct answer)
- Geo-redundant storage (GRS)
- Read-access geo-redundant storage (RA-GRS)
- Zone-redundant storage (ZRS)
Correct answer: Locally redundant storage (LRS)
LRS replicates data three times within a single data center in the primary region.
Question 2: Which storage redundancy option synchronously replicates data across three availability zones in the primary region?
- LRS
- ZRS (Correct answer)
- GRS
- GZRS
Correct answer: ZRS
Zone-redundant storage (ZRS) copies data across three availability zones within the primary region.
Question 3: What is the primary benefit of geo-redundant storage (GRS) over LRS?
- Lower cost
- Protection against a regional outage (Correct answer)
- Faster read speeds
- Unlimited capacity
Correct answer: Protection against a regional outage
GRS copies data to a secondary region, protecting against a full regional outage.
Question 4: Which Azure Storage service is best suited for storing large amounts of unstructured data such as images and videos?
- Azure Files
- Azure Queue Storage
- Azure Blob Storage (Correct answer)
- Azure Table Storage
Correct answer: Azure Blob Storage
Azure Blob Storage is optimized for storing massive amounts of unstructured object data.
Question 5: Which access tier in Azure Blob Storage offers the lowest storage cost but the highest access cost and latency?
- Hot tier
- Cool tier
- Cold tier
- Archive tier (Correct answer)
Correct answer: Archive tier
The Archive tier has the lowest storage cost but data must be rehydrated before access.
Question 6: Which Azure storage service provides fully managed file shares accessible via the SMB protocol?
- Azure Files (Correct answer)
- Azure Blob Storage
- Azure Disk Storage
- Azure Table Storage
Correct answer: Azure Files
Azure Files offers managed cloud file shares accessible through SMB and NFS.
Question 7: What does read-access geo-redundant storage (RA-GRS) add compared to standard GRS?
- Three more local copies
- Read access to the secondary region (Correct answer)
- Write access to all regions
- Free data egress
Correct answer: Read access to the secondary region
RA-GRS allows read access to data in the secondary region even when the primary is available.
