NEW QUESTION # 15
You are code-checking your colleague's process model before marking it as Ready for Deployment.
Which three best practices should be applied? (Choose three.)
- A. All nodes should have exception flows
- B. All outgoing flows from a gateway should be labeled
- C. All XOR/OR gateways should have a single incoming ow.
- D. Node inputs should not make the same query call more than once.
- E. Activity chaining should be added to the majority of flows.
Answer: B,C,D
Explanation:
Explanation
Three best practices that should be applied when code-checking a process model are:
* All XOR/OR gateways should have a single incoming flow. This is because XOR/OR gateways are used to split the process flow based on a condition or an event. Having multiple incoming flows to a gateway can cause confusion and ambiguity about the logic and order of execution. If multiple incoming flows are needed, they should be merged into a single flow using an AND gateway before reaching the XOR/OR gateway.
* All outgoing flows from a gateway should be labeled. This is because labels provide clarity and readability to the process model. They also help to document the business logic and rules that determine the path of execution. Labels should be concise, descriptive, and consistent throughout the process model.
* Node inputs should not make the same query call more than once. This is because repeated query calls can negatively impact the performance and efficiency of the process model. They can also cause data inconsistency and duplication if the query results change over time. Node inputs should use variables or rules to store and reuse query results whenever possible.

- C. Document can be uploaded but cannot be restricted.
- D. Configure Validation rules wherever required.
Answer: B
NEW QUESTION # 19
Application users are seeing long wait times between two forms they need to complete for a case.
While reviewing the process model, you identify that activity chaining has been used throughout the process model, including unattended nodes.
Which three actions can you take to make the process model more efficient? (Choose three.)
- A. Move transactions that can be done asynchronously outside of the chain.
- B. Shorten long process chains by combining transactions into the smallest number of nodes.
- C. Avoid chaining system nodes like Integrations.
- D. Use MNI for unattended nodes and chain where possible.
- E. Reduce the number of swim lanes.
Answer: A,B,C
NEW QUESTION # 20
During the design review, you identified slow-operating expression rules querying a specific data store.
Which metric from the data_store_details.csv file will help you understand the "number of operations against data store?" (Choose the best answer.)
- A. Total Count
- B. Transform Count
- C. Execute Count
- D. Query Count
Answer: A
Explanation:
Explanation
The metric from the data_store_details.csv file that will help you understand the number of operations against data store is Total Count. This metric represents the total number of queries, inserts, updates, deletes, and executes performed against the data store during the specified time period. You can use this metric to identify which data stores are heavily used and may need performance tuning or scaling. References: [Data Store Details Report], [Data Store Metrics]
NEW QUESTION # 21
You need to build a process model that transforms a large data set.
Which two things should you ensure to include in your process model? (Choose two.)
- A. A subprocess is called using "Multiple Node Instances (MNI)" to perform the transformation on each item in the data set.
- B. An XOR gateway is added before the transformation node, to check for empty/null values.
- C. A loop is created within the process model that increments on each iteration, updating that particular row in the data set.
- D. The transformation is applied with an expression rule that takes the data set as an input, and loops through the dataset using a looping function, such as foreach.
Answer: B,D
Explanation:
Explanation
When building a process model that transforms a large data set, two things that should be ensured to include in the process model are an XOR gateway before the transformation node, to check for empty/null values, and a transformation applied with an expression rule that takes the data set as an input, and loops through the dataset using a looping function, such as foreach. These things can help to improve the performance and reliability of the process model. The XOR gateway can prevent unnecessary processing of empty or null data sets, which can save time and resources. The expression rule can perform the transformation in one transaction, instead of using multiple nodes or subprocesses, which can reduce the memory footprint and the database load of the process model. Therefore, the correct answers are B and D.

NEW QUESTION # 22
You need to find a list of expression rules that are causing performance issues, or have caused performance issues in the last 30 days.
What should you do?
- A. Access the Rule Performance tab in the Administration Console.
- B. Inspect the application server log.
- C. Observe the runtime of all test cases.
- D. Use the Monitoring tab to find rules with a low completion percentage.
Answer: A
NEW QUESTION # 23
You need to create a plug-in to perform a job in the background. The plug-in should not be available under an expression rule, connected system, or the process model.
What type of plug-in should you create? (Choose the best answer.)
- A. Smart service
- B. Servlet
- C. Connected systems
- D. Function
Answer: B
Explanation:
Explanation
The type of plug-in that should be created to perform a job in the background and not be available under an expression rule, connected system, or the process model is a servlet plug-in. A servlet plug-in is a plug-in that allows you to create custom servlets that can be accessed through a URL. Servlets are Java classes that run on a web server and handle requests and responses. Servlet plug-ins can be used to perform background tasks, such as sending notifications, logging events, or integrating with external systems, without exposing them to the end users or developers.

NEW QUESTION # 24
Your organization requires a process to be initiated via an Appian web API.
Which HTTP request methods should the API use?
- A. CONNECT
- B. POST
- C. GET
- D. HEAD
Answer: B
Explanation:
Explanation
The question is about initiating a process via an Appian web API. The HTTP request method that the API should use is POST, as it is the method that allows sending data to the server and creating or updating a resource. In this case, the data would be the process parameters and the resource would be the process instance. The other options are not suitable for this purpose, as they either do not allow sending data or do not create or update a resource. References:
* HTTP Request Methods
* Start Process Web API
NEW QUESTION # 25

What is correct representation of Appian best practices? (Choose the best answer.)
- A. Pie charts should only be used to represent data that can be placed into identical categories.
- B. Try to use multiple pie charts when comparing multiple sets of data.
- C. Use pie charts to show proportional data.
- D. Use as many slices as possible.
