Add more process execution engines.

Add more application server memory.

Switch from a records-centric to a process-centric design.

QUESTION 60
You have been asked to produce a Tempo report, with the following requirements:
The report should display in Appian.
The data is held in a business database, but performance in Appian is a key requirement.
Which three actions can you take to minimize the performance impact of your report? (Choose three.)

Display the report as a task report on the Tasks tab.

Limit the number of series values and categories in the report.

Use local variables in your report interface to avoid redundant database queries.

Use the query process analytics function to retrieve the data.

Perform aggregation in the database using a view prior to reading the data into Appian.

QUESTION 61
What are three things you can do to improve the memory usage of a process model? (Choose three.)

Configure process variables to be parameters.

Reduce the number of process variables.

Avoid storing large blocks of text in process variables.

Split large nodes into many smaller nodes.

Pass data directly to activity nodes and smart services.

Explanation
The question is about improving the memory usage of a process model. The following are three things you can do for this purpose:
* Reduce the number of process variables. This means using fewer or smaller process variables to store data in the process model, as each process variable consumes memory and resources. You should only use process variables that are necessary for the process logic or data flow, and avoid storing redundant or temporary data in process variables.
* Avoid storing large blocks of text in process variables. This means using other methods to store or handle large blocks of text, such as documents, constants, or expression rules, rather than process variables. This can reduce the memory usage of the process model, as large blocks of text can consume a lot of memory and resources, and affect the performance or stability of Appian.
* Pass data directly to activity nodes and smart services. This means using parameters or inputs to pass data to activity nodes and smart services, rather than process variables. This can reduce the memory usage of the process model, as parameters or inputs are only evaluated when needed, and do not persist in memory.
The following are not things you can do to improve the memory usage of a process model:
* Configure process variables to be parameters. This is not possible, as process variables and parameters are different types of data elements in a process model. Process variables are used to store data throughout the process model, while parameters are used to pass data to or from a subprocess or an expression rule.
* Split large nodes into many smaller nodes. This is not advisable, as it can increase the complexity and maintenance overhead of the process model, and may not reduce the memory usage significantly. You should only split nodes when it makes sense for the process logic or functionality, and not for the sake of reducing node size.

* Process Variables
* Documents
* Constants
* Expression Rules
* Parameters

QUESTION 62
You are presenting data through data visualization.
Match the chart types to the data they are best suited to represent. Each answer will be used once.
Note: To change your responses, you may deselect your response by clicking the blank space at the top of the selection list.

QUESTION 63
HOTSPOT
Match each of the business data concepts to an Appian data type. Each data type may be used once, more than once, or not at all.

QUESTION 64
A car insurance company wants to build an application that processes insurance claims. Appian will receive a claim in a JSON document and return a decision about whether the company should pay the claim.
Match each system requirement to the Appian object that could be used to implement the requirement. Each answer will be used once.

QUESTION 65
You are designing a case management application. The initiator creates a case, and the reviewer reviews it approximately 7 days later.
You have already designed a process model for the initiators to create the case.
Which process model design will result in the lowest memory impact? (Choose the best answer.)

When all case details are entered, the case appears as a case record, and when the reviewer is ready to review the record, they can do so via a related action from the case record.

When all case details are entered, the process flow will proceed and assign a task to the reviewer to review the record.

When all case details are entered, the process flow will call a Start Process node to initialize a review process model for the reviewer.

When all case details are entered, the process flow will call a Sub-Process node to initialize a review process model for the reviewer.

QUESTION 66
You are using pie charts.
What is correct representation of Appian best practices? (Choose the best answer.)

Use as many slices as possible.

Pie charts should only be used to represent data that can be placed into identical categories.

Use pie charts to show proportional data.

Try to use multiple pie charts when comparing multiple sets of data.

QUESTION 67
