HOTSPOT (Drag and Drop is not supported)
You work for a multinational company that has Azure and Common Data Service environment in the United States (UTC-7) and Japan (UTC+9).

You create Azure Functions for each location to update key data.
You need to configure the functions to run at 4:00 AM on weekdays at each location.

Which schedule formats should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: 0 0 4 * * 1-5
Azure Functions uses the NCronTab library to interpret NCRONTAB expressions.
An NCRONTAB expression is similar to a CRON expression except that it includes an additional sixth field at the beginning to use for time precision in seconds:

{second} {minute} {hour} {day} {month} {day-of-week}

NCRONTAB time zones
The numbers in a CRON expression refer to a time and date, not a time span. For example, a 5 in the hour field refers to 5:00 AM, not every 5 hours.
The default time zone used with the CRON expressions is Coordinated Universal Time (UTC).
To have your CRON expression based on another time zone, create an app setting for your function app named WEBSITE_TIME_ZONE.

1-5 is weekdays
Box 2: 0 0 4 * * 1-5

DRAG DROP (Drag and Drop is not supported)
You are creating a PowerApps connector between Dynamics 365 Sales and Slack.

You must generate a Slack notification whenever a new product is added to Dynamics 365 Sales. You must not be required to sign in directly into Dynamics 365 Sales to generate notifications. You created a Power Apps connector between Dynamics 365 Sales in Slack to enable this to happen.

You need to configure the appropriate security for each scenario? Which security components should you configure?

NOTE: Each correct selection is worth one point.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: Security roles
A security role defines how different users, such as salespeople, access different types of records. To control access to data, you can modify existing security roles, create new security roles, or change which security roles are assigned to each user. Each user can have multiple security roles.
Security role privileges are cumulative: having more than one security role gives a user every privilege available in every role.
Each security role consists of record-level privileges and task-based privileges.

Box 2: OAuth
Oauth 2.0 is the most frequently used type, which uses the Oauth 2 authentication framework to authenticate with the service. Before using this authentication type, you'll need to register your application with the service so that it can receive access tokens for the users.
For example, Register the application in Azure AD shows how to register an application with the Azure Active Directory service.
During the connection creation process, the user will be asked to enter the credentials for login to the service. These credentials will be used by the application to get an authorization token. For every request, this authorization token will be sent to your service through the Authorization header.

Box 3: Basic Authentication
Basic Authentication is the simplest type of authentication, where the user just has to provide the username and password to create the connection.
Note: Before using any connector in Azure Logic Apps, Microsoft Power Automate, or Microsoft Power Apps, the user needs to create a connection by authenticating to the backend service.
Authentication types

The different types of authentication that are currently supported are:
-No authentication
-Basic authentication
-Api Key based authentication
-Oauth 2.0

NOTE: Each correct selection is worth one point.
Select and Place:

  1. See Explanation section for answer.

Box 1: PreValidation
For the initial operation, this stage will occur before the main system operation.

Box 2: No
Tracking user changes
Tracking user changes is a round of one or more GET requests with the delta function. You make a GET request much like the way you list users, except that you include the following:

The delta function.
A state token (deltaToken or skipToken) from the previous GET delta function call.

Delta tokens are only valid for a specific period before the client application needs to run a full synchronization again. For directory objects (application, administrativeUnit, directoryObject, directoryRole, group, orgContact, oauth2permissiongrant, servicePrincipal, and user), the limit is 7 days.
