Question 1

Single choice

You are just starting with a new team that has been working together on an application for months. They ask you toreview some of their views thathave been degrading inperformance.

The viewsare highly complex with hundreds of lines of SOL What is the first step in troubleshooting the degradation?

Go through the entire database structure to obtain on overview, ensure you understand the business needs, andthen normalize the tables to optimizeperformance.

Run an explain statement on the views, identify criticalareas of improvement that can be remediated and without business knowledge

Go through all of the tables one by one to identify which of the grouped by. ordered by.or joined keys are currently indexed

Browse through the tables, note any tables that contain a large volume of null values, and work with your team to plan for table restructure.

Question 2

Single choice

You are asked to design a case management system for a client in addition to storing some basic metadata about a case, one of the client s requirements Is the ability for users to update a case The client would like any user in their organization of 500 people to be able to make these updates The users are all based in the company's headquarters, and there will be frequent cases where users are attempting to edit the same case. The client wants to ensure no information Is lost when these edits occur and does not want the solution to burden their process administrators with any additional effort.

Which data locking approach should you recommend?

Allow edits without locking the case GDI

Use the database lo implement tow lewd pessimistic locking.

Add an ersion annotation to the case COT to manage Vie locking

Design a process report and query to determine who opened the edit form first

Question 3

Multiple choice

You need to design a complex Appian integration to call a RESTful API. The RESTful API will be used to

update a case in a customer's legacy system.

What are three prerequisites for designing the integration?

Define the HTTP method that the integration will use.

Understand the content of the expected body. Deluding each field type and their limits

Understand whether this integration will be used in an interface or in a process model

Understand the different error codes managed by the API and the process of error handing m Appall

Understand the business rules to be applied to ensure the business logic of the data

Correct answers: A, B, D

Explanation

To design a complex Appian integration to call a RESTful API, you need to have some prerequisites, such as: Define the HTTP method that the integration will use. The HTTP method is the action that the integration will perform on the API, such as GET, POST, PUT, PATCH, or DELETE. The HTTP method determines
how the data will be sent and received by the API, and what kind of response will be expected. Understand the content of the expected body, including each field type and their limits. The body is the data that the integration will send to the API, or receive from the API, depending on the HTTP method. The body can be in different formats, such as JSON, XML, or form data. You need to understand how to structure the body according to the API specification, and what kind of data types and values are allowed for each field.
Understand the different error codes managed by the API and the process of error handling in Appian. The error codes are the status codes that indicate whether the API request was successful or not, and what kind of problem occurred if not. The error codes can range from 200 (OK) to 500 (Internal Server Error), and each code has a different meaning and implication. You need to understand how to handle different error codes in Appian, and how to display meaningful messages to the user or log them for debugging purposes.
The other two options are not prerequisites for designing the integration, but rather considerations for implementing it.
Understand whether this integration will be used in an interface or in a process model. This is not a prerequisite, but rather a decision that you need to make based on your application requirements and design. You can use an integration either in an interface or in a process model, depending on where you need to call the API and how you want to handle the response. For example, if you need to update a case in real-time based on user input, you may want to use an integration in an interface. If you need to update a case periodically based on a schedule or an event, you may want to use an integration in a process model. Understand the business rules to be applied to ensure the business logic of the data. This is not a prerequisite, but rather a part of your application logic that you need to implement after designing the integration. You need to apply business rules to validate, transform, or enrich the data that you send or receive from the API, according to your business requirements and logic. For example, you may need to check if the case status is valid before updating it in the legacy system, or you may need to add some additional information to the case data before displaying it in Appian.

Question 4

Single choice

Your Appian project just went live with the following environment setup; DEV > TEST (SIT/DAT) > PROD

Your client is considering adding a support team to manage production defects and minor enhancements, white the original development team focuses on Phase 2 Your client is asking you for a new environment strategy that will have the least impact on Phase 2 development work.

Which option involves the lowest additional server cost and the least code retrofit effort?

Phase 2 development work steam: DEV > TEST (SIT) > STAGE (UAT) > PROO Production support
work stream DEV > TEST2 (SIT/UAT)>PROO

Phase 2 development work Stream: DEV > TEST (SIT) > STAGE (UAT) > PROO Production support
work stream DEV2 > STAGE (S1T/UAT) > PROD

Phase 2 development work stream: DEV > TEST (SIT/UAT) >PROD Production support work stream
DEV > TEST2 (SIT/UAT) > PROO

Phase 2 development work stream: OEV > TEST (Srr/DAT) > PROO Production support work stream.
DEV2 > TEST (SIT/UAT) > PROD

Question 5

Single choice

You are reviewing the Engine Performance Logs in Production for a single application thathas been live for six months. This application experiences concurrent user activity and has a fairly sustained load during business hours. The client has reported performance issues with the application during business hours.

During your investigation, you notice a high Work Queue - Java Work Queue Size value in the logs You also notice unattended process activities, including timer events and sending notifications emails, are taking far longer to execute than normal.

The client Increased the number of CPU cores prior to the application going live

What is the next recommendation?

Add more engine replicas.

Optimize slow-performing user interfaces.

Add more application servers.

Add execution and analytics shards

Question 6

Multiple choice

You are the lead developer for an Appian project, in a backlog refinement meeting You are presented with the following user story.

As a restaurant customer. I need to be able to place my food order online to avoid waiting in line for take out.'

Which two functional acceptance criteria would you consider 'good'?

The user will click Save, and the order information will be saved in the ORDER table and have audit history

The user will receive an email notification when their order is completed.

The system mutt handle up to 500 unique orders per day

The user cannot submit the form without filling out all required fields.

Question 7

Multiple choice

You ate in a backlog refinement meeting with the development team and the product owner. You review a story for an integration Involving a third-party system. A payload will be sent from the Appian system through the integration to the third-party system. The story is 21 points on a Fibonacci scale, and requires development from your Appian learn, as well as the technical resources from the third-party system. This item is crucial to your project s success.

What are the two recommended steps to ensure this story can be developed effectively?

Acquire testing steps from QA resources

Identify subject matter experts (SMEs) to perform user acceptance testing (UAT)

Maintain a communication schedule with the third-party resources

Break down the item into smaller stones

Correct answers: C, D

Explanation

To ensure that this story can be developed effectively, you should take two recommended steps: Maintain a communication schedule with the third-party resources. Communication is key when working on an integration involving a third-party system, as it can help to clarify the requirements, expectations, and dependencies of both parties. By maintaining a communication schedule, you can ensure that you have regular and timely updates on the progress, issues, and feedback of the integration. You can also use communication tools, such as email, chat, or video conferencing, to facilitate the communication and collaboration between your Appian team and the third-party resources.
Break down the item into smaller stories. Breaking down a large and complex story into smaller and simpler stories can help to make the development process more manageable and efficient. By breaking down the item into smaller stories, you can reduce the scope and complexity of each story, and focus on delivering one feature or functionality at a time. You can also prioritize and assign the stories to different developers, and track their status and completion more easily. The other options are not as effective.
Option A, acquiring testing steps from QA resources, is not a step to ensure that the story can be developed effectively, but rather a step to ensure that the story can be tested effectively. Option B, identifying subject matter experts (SMEs) to perform user acceptance testing (UAT), is also not a step to ensure that the story can be developed effectively, but rather a step to ensure that the story can be validated effectively. Option E, adding a view that joins the customer data to the data used in calculation, is not a step to ensure that the story can be developed effectively, but rather a design decision that may or may not be appropriate for the integration.

Question 8

Single choice

Your application contains a process model that Is scheduled to run daily at a certain time, which kicks off a user input task to a specified user on the 1ST time zone for morning data collection.
The time zone is set to the (default) pm!timezone.

In this situation, what does the pm!
tinezone reflect?

The time zone of the server where Applan is intuited

The line zone of the user who most recently published the process model

The default time zone for the environment as specified in the Administration Console

The time zone of the user who is completing the input task.

Question 9

Single choice

As part of your implementation workflow, users need to retrieve data stored in a third-party Oracle database on an interface. You need to design a way to query this information.

How should you set up this connection and query the data?

Configure a Query DataBase node within the process model Then, type in the connection information, as well as a SQL query to execute and return the data in process variables.

Configure a limed utility process that queries data from the thirdparty database daily, and stores It in the Applan business database, Then use alqueryEntity eating the Applan data source to retrieve the data.

Configure an expression-backed record type, calling an API to retrieve the data from the third-party database. Then, use allqueryRecordType to retrieve the data.

in the Administration Console configure the third-party database as a `'New Data Source,'' Then, use
alqueryEntity to retrieve the data.
