Passing the 70-532 Developing Microsoft Azure Solutions Certification Exam - Quick Facts

This is another installment of my series of blog post on passing the 70-532 Developing Microsoft Azure Solutions certification exam. This time we are going to look at several facts about particular behaviors or features of Azure services.

Feel free to add new facts on Github where all certification materials are hosted. You can find the Quick Facts file in the docs folder.

The Facts

Here is a list of the facts:

Cloud Services

  • Role startup tasks cannot directly execute a Powershell script – use console application or a batch file that starts the PowerShell script.
  • Setting RoleEnvironmentChangingEventArgs.Cancel to true will take the respective instance offline and bring it back again after the configuration changes have been applied.

SQL

  • SQL Server service tier cannot be changed when Geo-Replication is enabled.
  • Restore window for Basic tier is 7 days.
  • Restore window for Standard tier is 14 days.
  • Restore window for Premium tier is 35 days.

Redis Cache

  • Port should not be specified in the connection string.
  • Sharding/clustering is only available with the Premium plans.

Azure Storage

  • Get Queue Metadata is used to retrieve the approximate size of the queue.
  • Shared Access Signature without Stored Access Policy can only be revoked by changing the account key.
  • Page Blobs are optimized for random I/O operations.
  • Block Blobs are optimized for sequential I/O operations.
  • Zone redundant storage does not support page blobs.

Virtual Machines

  • Sysprep with Generalzie option is used to prepare a VM to be captured as an image.
  • Waagent with Deprovision option is used to prepare a Linux to be captured as an image.
  • Only VMs in the same cloud service can be part of an availability set.

Access Control Lists

  • When an endpoint is first created, all traffic is permitted for that endpoint.
  • When one or more Permit rules are added, traffic is implicitly denied for all IP ranged not included in the Permit rules.
  • When one or more Deny rules are added, traffic is implicitly allowed for all IP ranged now included in the Deny rules.
  • No implicit rules are applied when both Permit and Deny rules are used.

Cloud Storage

  • CloudQueue.FetchAttributes must be used before ApproximateMessageCount property can be read.
  • ApproximateMessageCount provides the approximate number of messages in the queue.

Web Apps

  • When swapping, App Settings can be configured to be swapped or to stick.
  • When swapping, Configuration settings can be configured to be swapped or to stick.
  • When swapping, diagnostic settings are always swapped.
  • When swapping, endpoints are not swapped.
  • When swapping, Webjob content is swapped.
  • When swapping, Webjob schedulers are not swapped.

As always, feel free to share your feedback in the commend section below.
