In what order should the Queue Items be processed by a single robot executing a Performer workflow?
In what order should the Queue Items be processed by a single robot executing a Performer workflow?
正解：
Explanation:
The Queue Items should be processed by a single robot executing a Performer workflow in the following order:
EmployeeID1
EmployeeID4
EmployeeID8
EmployeeID3
EmployeeID6
EmployeeID9
EmployeeID5
EmployeeID2
EmployeeID7
A queue is a container that holds an unlimited number of items that can be processed by a robot1. A queue item can have a deadline and a priority, which affect the order in which the robot retrieves the items from the queue2. The Performer workflow is a part of the REFramework template that processes the queue items using the Get Transaction Item activity3. The order of queue execution is determined by the following rules4:
Items that have a deadline are processed first, in order of priority and according to the set deadline for items with the same priority.
Items that have no deadline are processed next, in order of priority and according to the rule First In, First Out for items with the same priority.
Based on these rules and the exhibit, the order of queue execution is as follows:
EmployeeID1 has the earliest deadline (2050-01-01) and high priority, so it is processed first.
EmployeeID4 has the same deadline as EmployeeID1, but normal priority, so it is processed second.
EmployeeID8 has the same deadline and priority as EmployeeID4, but it was added later to the queue, so it is processed third.
EmployeeID3 has the next earliest deadline (2050-01-02) and high priority, so it is processed fourth.
EmployeeID6 has the same deadline as EmployeeID3, but normal priority, so it is processed fifth.
EmployeeID9 has the same deadline and priority as EmployeeID6, but it was added later to the queue, so it is processed sixth.
EmployeeID5 has no deadline, but high priority, so it is processed seventh.
EmployeeID2 has no deadline and normal priority, so it is processed eighth.
EmployeeID7 has no deadline and low priority, so it is processed ninth.

How should the computation of the signature be done for client apps that receive Orchestrator requests and need to check their authenticity?

The correct sequence for the computation of the signature for client apps that receive Orchestrator requests and need to check their authenticity is:
Retrieve the X-UiPath-Signature HTTP header. This header contains the signature of the request body, encoded in Base64. (UiPath Orchestrator documentation1) To obtain the raw signature bytes, decode the value of the header from Base64. You can use any tool or library that supports Base64 decoding. (UiPath Orchestrator documentation1) Compute the hash using SHA256 and the signing key (UTF-8 encoded). The signing key is a secret value that is shared between Orchestrator and the client app. You can use any tool or library that supports SHA256 hashing. (UiPath Orchestrator documentation1) Compare the computed signature to the value from X-UiPath-Signature HTTP header. If they match, then the request is authentic and has not been tampered with. If they do not match, then the request is invalid and should be rejected. (UiPath Orchestrator documentation1) References:

A developer is building an automation that must interact with a destination remote computer reached by jumping through multiple RDP connections, as described by the following scenario:
- The Robot is installed on Machine A, which connects through RDP to Machine B.
- From Machine B another RDP connection is opened to Machine C, where the automation must be performed.
Which of the following scenarios is appropriate for the developer who wants to use UI Automation activities?

A developer implemented a process using the Robotic Enterprise Framework and an Orchestrator queue. The MaxRetryNumber from the "Config.xlsx" file is set to "1" and the Max # of retries from the Queue settings from Orchestrator is set to
"2". At runtime, the first transaction item throws a Business Exception.
How many times will the transaction be retried?

A developer needs to take a screenshot of the state of the machine while the robot is running and then send the screenshot as an email. What is the correct sequence of steps that should be performed?
Instructions: Drag the Description found on the left and drop on the correct Step found on the right.
Instructions: Drag the Description found on the left and drop on the correct Step found on the right.
正解：
Explanation:
The correct sequence of steps that should be performed is:
Step 1 = Use a Take Screenshot activity to capture the state of the machine. The output is an Image variable, for example img_screenshot.
Step 2 = Use a Save Image activity to save the image to a local file. Supply the FileName (e.g.
screenshot.png) and the Image property should be the variable created in step 1.
Step 3 = Use a Send Outlook Mail Message activity to compose and send the email. Configure the Attachments property to include the file path of the image saved in step 2 .
Step 4 = Optionally, use a Delete File activity to delete the image file from the local drive after sending the email. Supply the Path property with the same file path as in step 3.
For more information on how to use these activities in UiPath Studio 2021 10, you can refer to these documents:
