AZURE DEVELOPER ASSOCIATE QUESTIONS WITH
ACCURATE ANSWERS
1.
Which of the following can be used to manage governance across multiple Azure
subscriptions?
Azure initiatives
Management groups
Resource groups correct answer Management groups
1. Suppose you have a distributed application with a web service that
authenticates users. When a user logs on, the web service notifies all the client
applications so they can display that user's status as "Online". Is the login
notification an example of a message or an event? correct answer Event
2. Suppose you have a distributed application with a web service that lets users
manage their account. Users can sign up, edit their profile, and delete their
account. When a user deletes their account, your web service notifies your data
layer so the user's data will be removed from the database. Is the delete-account
notification an example of a message or an event? correct answer Message
3 queuing system messaging gurantees: correct answer 1) At-Least-Once Delivery
2) At-Most-Once Delivery
3) First-In-First-Out (FIFO)
4 levels of organizing structure in Azure(top to bottom): correct answer 1)
Management groups
,2) Subscriptions
3) Resource groups
4) Resources
A CRON expression is a string that consists of six fields that represent a set of
times. The order of the six fields in Azure is: {second} {minute} {hour} {day}
{month} {day of the week}. Suppose you needed a CRON expression that meant
"every day", what special character would you put in the {day of the week}
position?: correct answer *
Access control boundary: correct answer Azure applies access-management
policies at the subscription level, and you can create separate subscriptions to
reflect different organizational structures. An example is that within a business,
you have different departments to which you apply distinct Azure subscription
policies. This billing model allows you to manage and control access to the
resources that users provision with specific subscriptions.
Activity functions: correct answer the basic units of work in a durable function
orchestration.
Additionally, most binding types also need a fourth property: correct answer
Connection - Provides the name of an app setting key that contains the
connection string.
An orchestration function provides these extra benefits: correct answer You can
define the workflows in code. You don't need to write a JSON description or use a
workflow design tool.
, Functions can be called both synchronously and asynchronously. Output from the
called functions is saved locally in variables and used in subsequent function calls.
Azure checkpoints the progress of a function automatically when the function
awaits. Azure may choose to dehydrate the function and save its state while the
function waits, to preserve resources and reduce costs. When the function starts
running again, Azure will rehydrate it and restore its state.
Async HTTP APIs(workflow pattern): correct answer This pattern addresses the
problem of coordinating state of long-running operations with external clients. An
HTTP call can trigger the long-running action. Then, it can redirect the client to a
status endpoint. The client can learn when the operation is finished by polling this
endpoint.
At-Least-Once Delivery: correct answer each message is guaranteed delivery to at
least one of the components that retrieve messages from the queue.
At-Most-Once Delivery: correct answer each message is not guaranteed for
delivery, and there is a small chance that it may not arrive.
- no chance that the message will be delivered twice
Availability zones: correct answer physically separate datacenters within an Azure
region.
Azure App Service plan: correct answer allows you to avoid timeout periods by
having your function run continuously on a VM that you define.
