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.
Azure Cosmos DB(trigger): - CORRECT ANSWER: Start a function when inserts and
updates are detected.
benefits of queues: - CORRECT ANSWER: 1) increased reliability
2) message delivery gurantee
3) transactional support
Billing boundary: - CORRECT ANSWER: This subscription type determines how an
Azure account is billed for using Azure. You can create multiple subscriptions for
