Zorluk: OrtaBlob, File, and Disk Storage Solutions

An online gaming platform is deploying its backend database on Azure Virtual Machines. The database transaction logs require storage that supports sub-millisecond write latency. Additionally, game assets in Azure Storage must be securely shared with external developers using temporary access tokens that can be quickly revoked if a leak occurs. The entire storage solution must remain available even during a local zone outage in the primary Azure region.

Which two configurations should you include in the storage design? (Select two).

  1. Use Premium SSD v2 managed disks with Zone-Redundant Storage (ZRS) for the database transaction logs.Cevap
  2. Generate Shared Access Signature (SAS) tokens associated with a stored access policy for sharing game assets.Cevap
  3. C
    Use Standard HDD managed disks with Zone-Redundant Storage (ZRS) for the database transaction logs.
  4. D
    Use Locally Redundant Storage (LRS) Premium SSD v2 managed disks for the database transaction logs.
  5. E
    Generate ad-hoc Shared Access Signature (SAS) tokens with a five-year lifetime for sharing game assets.

Cevap

Use Premium SSD v2 managed disks with Zone-Redundant Storage (ZRS) for the database transaction logs, and generate Shared Access Signature (SAS) tokens associated with a stored access policy for sharing game assets.
Premium SSD v2 managed disks offer high performance and sub-millisecond latency, making them ideal for transaction logs, while ZRS provides protection against zone outages. Using stored access policies for Shared Access Signatures (SAS) ensures that access to assets can be instantly revoked by modifying or deleting the policy, meeting the security and administrative requirements.

Adım Adım Çözüm

1
Analyze the database performance and availability requirements.
The transaction logs require sub-millisecond latency and zone redundancy.
Database performance demands high IOPS/throughput and low latency, while the system must survive a zone outage.
2
Evaluate the disk storage types and redundancy configurations.
Premium SSD v2 disks with ZRS meet both the performance and zone-redundancy requirements.
Standard HDD/SSD cannot meet sub-millisecond latency, and LRS does not survive a zone outage.
3
Analyze the asset sharing security and revocation requirements.
The access tokens must be temporary and easily revocable.
Using stored access policies with SAS tokens allows instant revocation by deleting or modifying the policy, whereas ad-hoc SAS tokens cannot be easily revoked without rotating the primary/secondary keys.

Anahtar Kavram

Selecting optimal disk types for performance, choosing the appropriate redundancy level for high availability, and securing blob storage access using stored access policies.
