Zorluk: OrtaBlob, File, and Disk Storage Solutions

You are designing the storage infrastructure for a reporting application migrating to Azure. The application components have the following storage requirements:

- The database transaction logs require single-digit millisecond write latency.
- The storage hosting the transaction logs must remain available if a single datacenter in the primary region fails.
- External partners need temporary access to raw log files stored in Azure Blob Storage. You must be able to revoke this access immediately if a security compromise occurs.

Which two storage configurations should you include in the design?

  1. Configure the database transaction logs to use Premium SSD managed disks with Zone-Redundant Storage (ZRS).Cevap
  2. Generate Shared Access Signatures (SAS) associated with a stored access policy for the raw log files.Cevap
  3. C
    Configure the database transaction logs to use Standard SSD managed disks with Zone-Redundant Storage (ZRS).
  4. D
    Configure the database transaction logs to use Premium SSD managed disks with Locally Redundant Storage (LRS).
  5. E
    Generate ad-hoc Shared Access Signatures (SAS) with a long expiration time directly in the URI for the raw log files.

Cevap

Configure the database transaction logs to use Premium SSD managed disks with Zone-Redundant Storage (ZRS), and generate Shared Access Signatures (SAS) associated with a stored access policy for the raw log files.
The design satisfies all requirements by choosing Premium SSD disks to meet the performance criteria, configuring Zone-Redundant Storage (ZRS) to withstand a single datacenter outage, and using stored access policies to govern the SAS tokens so that access can be revoked immediately if necessary.

Adım Adım Çözüm

1
Select the disk tier that meets the single-digit millisecond latency requirement for database transaction logs.
Premium SSD is selected instead of Standard SSD.
Database transaction logs demand high IOPS and low latency, which Standard SSD cannot reliably provide.
2
Determine the redundancy option that protects against a single datacenter failure within the primary region.
Zone-Redundant Storage (ZRS) is selected instead of Locally Redundant Storage (LRS).
ZRS replicates data synchronously across three availability zones in the region, ensuring availability during a single zone/datacenter outage.
3
Select the secure access method for raw log files that allows immediate revocation.
SAS tokens associated with a stored access policy are selected instead of ad-hoc SAS tokens.
Stored access policies permit immediate revocation of the generated SAS by deleting or changing the expiration time of the policy.
