Zorluk: ZorCreate and Configure Virtual Machines

An administrator is planning the deployment of several Azure virtual machines (VMs) to support different enterprise workloads. Each workload has specific performance, placement, or security requirements.

Match each workload requirement to the most appropriate Azure VM configuration feature or option.

  • A database VM that requires the ability to dynamically scale IOPS and throughput performance limits without restarting the virtual machine or causing downtime.Ultra Disk
  • A stateless web application VM pool that requires faster read/write latency to the OS drive and rapid VM re-imaging by deploying the OS directly onto the local host storage.Ephemeral OS Disk
  • A high-performance cluster requiring the lowest possible network latency by ensuring that virtual machines are physically located as close as possible to each other within the same physical data center.Proximity Placement Group
  • A compliant financial application VM that requires data written to both the OS and temporary disks to be encrypted directly on the physical host hosting the VM before transmission to Azure Storage.Encryption at Host

Cevap

To meet the requirements, match the dynamic performance scale database to Ultra Disk, the stateless web VM pool to Ephemeral OS Disk, the low-latency cluster to Proximity Placement Group, and the host-level encryption to Encryption at Host.
The correct matches align each workload requirement with its specific Azure VM architectural option:
- Dynamic performance adjustments of IOPS and throughput on the fly are unique to Ultra Disks.
- Storing the OS disk directly on the local VM host's storage to minimize latency and enable rapid re-imaging is the primary use case of Ephemeral OS Disks.
- Grouping VMs in close physical proximity within a single data center to reduce network latency is achieved using Proximity Placement Groups.
- Encrypting data directly at the virtual machine physical host level before sending it over the network to Azure Storage is configured using Encryption at Host.

Adım Adım Çözüm

1
Analyze the database requirement for dynamically adjusting storage performance (IOPS and throughput) without VM downtime.
Identify Ultra Disk as the appropriate storage option.
Ultra Disks allow modifying IOPS and throughput dynamically without detaching the disk or restarting the VM.
2
Evaluate the requirement for stateless VMs requiring low OS disk latency and rapid re-imaging using local host storage.
Identify Ephemeral OS Disk as the correct selection.
Ephemeral OS Disks utilize the local VM host's cache or temp disk instead of remote Azure Storage, enabling faster read/write latency and rapid re-imaging.
3
Analyze the requirement for reducing physical distance and network latency between VMs in a cluster.
Identify Proximity Placement Groups as the correct option.
Proximity Placement Groups group VMs physically close within the same data center to reduce inter-VM latency.
4
Identify the feature that encrypts OS and temp disks at the VM host level before sending data to Azure Storage.
Identify Encryption at Host as the correct option.
Encryption at Host ensures that data stored on the VM host (like temporary disk and OS/data disk caches) is encrypted at rest and encrypted end-to-end as it flows to Azure Storage.
