"Blob public access" default has changed again!

Module: 00

Lab/Demo: many

It looks like the default setting for "Blob public access" was changed sometime this week back to "Enabled". I have created several Storage Accounts yesterday and today and they all default "Blob public access" to "Enabled".

Module: 02: Implement Azure Functions

Lab/Demo: 04

Task: 03

Step: 02

Description of issue

RE: /Instructions/Labs/AZ-204_02_lab.md

In Lab "Exercise 4: Create a function that integrates with other services" on Task 3 ... Step 2 currently reads:
"From the App Service blade, locate and open the Integration pane for the GetSettingInfo function"

I believe it should read something like:
"Go to the Functions blade, select the GetSettingInfo function, and then select the Integration pane."

Repro steps:

1. Going to the App Service blade does not allow the student to access the Integrations pane for the GetSettingInfo function

Lab 12 - Redundant step to get instrumentation key

The following step can be removed as students are already asked to get this code earlier in the lab:

Get the value corresponding to the APPINSIGHTS_INSTRUMENTATIONKEY application settings key. This value was set automatically when you built your web app.`

Guidance AZ204

Module: ALL

Task: 00

Step: 00

Description of issue
Hello, I am looking for some guidance. I am intending on delivering the AZ204 course. I have up until now been delivering the AZ900 which is different as we know. I am looking for some guidance from a fellow MCT on some of the best approaches in delivering this course.

Slides, Demos and the balance between them. Any help would be appreciated email [email protected]

Should we move from Azure SQL Database to a flat file?

I would propose changing the lab to avoid use of the Azure SQL Database platform.

Reason: AZ-204 course material (PPTs, Skillpipe) has zero coverage of Azure SQL Database. This service is covered in DP-200, DP-201, DP-050, etc. Not in AZ-204. Students thus find the lab quite challenging and the references to Azure SQL Database quite unexpected.

Yes, I realize this change might involve essentially recreating the lab from scratch. I think it's justifiable give the benefits of aligning labs to course scope.

I welcome everyone's feedback on this proposal.

Lab 10 - "Register the Microsoft.EventGrid provider"

This task in the lab only verifies that the provider is registered, so the name is a little misleading.

Proposal:

1. Remove the task altogether, or
2. Change its title to better reflect contents. Ex. "Verify that the Microsoft.EventGrid provider is registered"

Incorrect storage account

Module: az-204

Lab/Demo: 02

Task: 03

Step: 05

Description of issue
Here: https://github.com/MicrosoftLearning/AZ-204-DevelopingSolutionsforMicrosoftAzure/blob/master/Instructions/Labs/AZ-204_02_lab.md#task-3-configure-an-http-triggered-function

On step 5, It says Storage account connection: Azure WebJobsStorage. However this appears to create a new storage account and not use the existing one which we uploaded to. In order to make it work, I had to create a new connection, and map it to my existing storage account.
Repro steps:

Code missing "PublicAccessType.Blob"

Module: 3

Lab: 3

Task: 2

Step: 6

In step 3, everything is ok:

await container.CreateIfNotExistsAsync(PublicAccessType.Blob);

But in step 6 "Observe the GetContainerAsync method, which should now include:"
the same line is

await container.CreateIfNotExistsAsync();

So it is missing the PublicAccessType.Blob

Students who copy the whole code from step 6 won't get the Task 5 working where this is tested, without setting the access level manually.

Lab 01 stopped working because of changes in How storage accounts are created by default.

Module: 01

Lab/Demo: 01

Task: 02

Lab 01 should have a "404 is expected" warning

Module: 01

Description of issue

Students are often confused at this point because they try to open the site and get a "not found" error - this is normal, because nothing has been published yet. An appropriately phrased note warning them would help. I thought one was there already, but maybe it's in another lab.

Implementing Optimistic and Pessimistic Concurrency

Hi,
I am going to raise this ticket but it is not an issue. I want help with implementing the accesscondition check which we could do in v11 dll. But I am struggling to implement it using v12 dll. I know we can create the BlobRequestCondition for the same but I am not sure how to chck for ETAG in that class. Can a example be created for the same.

Thanks in Advance

New Functions management experience impacts multiple labs

This impacts many steps in many labs - the new Functions management UI, which is basically the App Service management UI with some tweaks, was made the default after being in preview for a while. This means that most instructions in the AK and in some cases the non-AK around how to get to administrative management of Functions are wrong, in some cases very much so. A short-term fix is to tell the students to click the "Having issues" link at the top of the Overview of the new experience, but the proper long term fix is to revisit every use of Functions in every lab and fix the instructions. (This is a big fix.)

Active Azure Functions NuGet Issue [Referencing Azure.Storage.Blobs 12.4.0]

Module: 07

Lab/Demo: Lab

Task: Exercise 4/Task 2

Step: 03

Description of issue
Wrong version of the Azure.Storage.Blobs which leads to errors when you want to create the function, the reason being that 12.0 was not around when netcore 3.1 was released . You should use 12.4 instead of 12.0.

Repro steps:

Simplify cleanup instructions

I think the following steps can be removed from Task 1 in each lab to make the instructions simpler:

az group list
az group delete --help

Reason: The resource group is known for each lab. Only the precise command already listed in Task 2 needs to be executed.

Lab titles in TOC differ from lab titles in labs themselves

Please adjust the lab titles to make them consistent.

Edit: To clarify, this only impacts a few of the titles. Most titles are already consistent.

Incorrect JSON response from API Management xml-to-json outbound processing

Module: Lab: Creating a multi-tier solution by using services in Azure

Lab/Demo: Exercise 2: Build an API proxy tier by using Azure API Management

Task: Task 3: Manipulate an API response

Step: 11. Replace that block of XML with the following XML:

The xml-to-json outbound processing step in API Management returns invalid JSON. JSON does not allow for comments, but the returned data contains C-style comments. It should work fine in JavaScript but not with JSON parser.

Repro steps:

1. on step 11, add xml-to-json outbound processing step
2. on step 16, Observe the results of the API request, the response contains comments.

possible confusion from httprepl giving a Swagger warning

Module: 09

Lab/Demo: 09

Task: Ex 3 Task 4

Step: 2

When httprepl runs, it attempts to retrieve a Swagger API definition to help the tool user. The Logic App doesn't have one, so it returns a warning. Students sometimes see that warning and assume they've done something wrong since they weren't told to expect it. There should be a note indicating that it's expected. Maybe something like:

When you launch httprepl, it will attempt to find a Swagger definition, as described in Module 08. Because your Logic App does not have such a definition published, you will get a warning, stating "Unable to find a swagger definition". This is expected.

Lab 8 API Provision time

Module: 08

Lab/Demo: Creating a multi-tier solution

Exercise 2

Task: 02

In Lab 8, the estimated time is 45 minutes according to the lab manual.

I have yet to provision an API in less than 30-35 minutes and it usually takes > 40 minutes to provision. This always seems to have been the case in Azure.

The LAK in Ex.2, Task 2 has students create a new API and under Step 6(v) there is a note that says "wait for the new API to finish being created".

Should we not set an expectation that this will be at least 30 minutes? Or consider having the resource group and API created first before performing Exercise 1?

I read that "Azure Storage and will need to be tested to see if they work with or without public access:", and "To fix this, you need to go to Advanced tab and Enable Blob public access". But I do not see any Advanced tab or Enable Blob public access.
I find that public access for Blob is under Configuration, and it is Enabled.

Do I need to do the below steps also?
(i) Go to Storage Explorer (Preview)
(ii) Select the Container [images]
(iii) Manage Access
(iv) Superuser (Owner & Owning Group)
(v) Access: Read, Write, Execute

Announcement: Updates Incoming

We had a wave of lab updates being tested and slated for a release earlier this month. Unfortunately (or fortunately depending on your perspective), the Azure Functions UI update put us on a back foot completely.

We are still working behind the scenes to try and close all impacted issues by June 5.
