You need to architect a solution for the user profiles.
The solution must provide profile access in the event of a single point of failure.
Which of the following is the best solution for user profiles?
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer: B
Cloud Cache will provide profile access in the event of a single point of failure.
While other options may also store redundant copies of the profile but the copies are not available without intervention.
Option A is incorrect.
Using Recovery Services Vault to backup the profiles to a different region is not a recommended solution.
Option B is correct.
If you want synchronous replication for minimizing the data loss, then it is recommended to use FSLogix Cloud Cache.
Option C is incorrect.
Using Azure Files with Geo-zone redundancy GZRS storage account for storage profiles is not a recommended solution.
Option D is incorrect.
This solution may also store redundant copies of the profile but the copies are not available without intervention.

To provide profile access in the event of a single point of failure, we need to ensure that user profiles are stored in a resilient and redundant way. The given options are:
A. Using Recovery Services Vault to backup the profiles to a different region B. Using cloud cache for user profiles C. Using an Azure Files with Geo-zone redundancy GZRS storage account for storage profiles D. Using an Azure Files with Geo-redundant GRS storage account for storage profiles.
Option A: Using Recovery Services Vault to backup the profiles to a different region This option involves backing up user profiles to a Recovery Services Vault in a different region. This ensures that the profiles are protected from a single point of failure. However, this option does not provide real-time access to the profiles and requires a restore operation in case of a failure. Also, there may be a delay in the restore operation, depending on the size of the profiles.
Option B: Using cloud cache for user profiles This option involves using Azure Cache for Redis to cache user profiles. The cache is replicated across multiple nodes, providing high availability and fault tolerance. However, this option does not provide durable storage for the profiles, and the cache may be cleared at any time due to various reasons, including eviction policies and memory pressure.
Option C: Using an Azure Files with Geo-zone redundancy GZRS storage account for storage profiles This option involves storing user profiles in an Azure Files share with Geo-zone redundancy (GZRS). GZRS provides synchronous replication of the data across multiple zones within a region, ensuring that the data is protected from zone-level failures. However, GZRS does not protect against regional disasters, and the data may be lost in case of a regional outage.
Option D: Using an Azure Files with Geo-redundant GRS storage account for storage profiles This option involves storing user profiles in an Azure Files share with Geo-redundant (GRS) storage. GRS provides asynchronous replication of the data to a secondary region, ensuring that the data is protected from regional disasters. GRS also provides read-only access to the data in the secondary region, enabling quick failover in case of a primary region failure.
Considering the requirement of providing profile access in the event of a single point of failure, Option D (Using an Azure Files with Geo-redundant GRS storage account for storage profiles) is the best solution for user profiles. It provides both synchronous and asynchronous replication of the data, ensuring that the data is protected from both zone-level and regional failures. It also provides read-only access to the data in the secondary region, enabling quick failover in case of a primary region failure.
