Zorluk: OrtaConfigure Virtual Machine Scale Sets (VMSS)

An administrator is configuring a Virtual Machine Scale Set (VMSS) named `vmss-prod` that uses a Rolling upgrade policy. You need to configure the rolling upgrade settings to meet the following requirements:

* Ensure that a maximum of 25% of the total virtual machine instances are upgraded simultaneously.
* Configure a 10-minute delay after each batch of upgrades is completed to allow the application to stabilize.

Which two properties of the rolling upgrade policy should you configure? (Select two.)

  1. `maxBatchPercent`Cevap
  2. `pauseTimeBetweenBatches`Cevap
  3. C
    `maxUnhealthyUpgradedInstancePercent`
  4. D
    `cooldown`

Cevap

Configure the `maxBatchPercent` property to limit the percentage of instances upgraded in each batch, and configure the `pauseTimeBetweenBatches` property to set the stabilization delay between batches.
The property defining the maximum percentage of instances that can be upgraded in a single batch is `maxBatchPercent`, which directly satisfies the requirement to limit the upgrade to 25% of instances at a time. The property specifying the duration to pause after a batch is upgraded is `pauseTimeBetweenBatches`, which allows the application to stabilize for 10 minutes before the next batch begins.

Adım Adım Çözüm

1
Identify the property that limits the number of instances upgraded concurrently in a rolling upgrade batch.
The `maxBatchPercent` property controls the percentage of instances processed in each batch.
By setting this property to 25, you ensure that no more than 25% of the virtual machines in the scale set are upgraded at the same time.
2
Identify the property that introduces a pause or delay after a batch completes.
The `pauseTimeBetweenBatches` property accepts an ISO 8601 duration string to pause execution.
Setting this property to `PT10M` enforces a 10-minute wait time after completing a batch before the next batch begins, allowing the application to stabilize.
