An organization is migrating a legacy multi-tier web application and its backend database to Azure. The application runs on Linux virtual machines. The design has the following requirements:
* The web application servers require a shared file system that supports POSIX-compliant operations, including hard links, and must remain available in the event of an Azure availability zone outage.
* The database virtual machines require a dedicated high-performance disk for transaction logs that provides high write IOPS and sub-millisecond latency.
Which two storage configurations should you include in the design? (Select two.)
- Azure Files Premium tier using the NFS 4.1 protocol and configured with Zone-Redundant Storage (ZRS)Cevap
- Premium SSD managed disks for the database transaction logsCevap
- CStandard HDD managed disks for the database transaction logs
- DAzure Files Premium tier using the NFS 4.1 protocol and configured with Locally Redundant Storage (LRS)
Cevap
Azure Files Premium tier using the NFS 4.1 protocol configured with Zone-Redundant Storage (ZRS), and Premium SSD managed disks for database transaction logs.
To meet the requirements, the shared file system must be configured using Azure Files Premium tier with the NFS 4.1 protocol and Zone-Redundant Storage (ZRS) to ensure POSIX compliance (including hard links) and availability zone resilience. For the database transaction logs, Premium SSD managed disks must be selected to deliver the high IOPS and low latency necessary for database write operations.
