NEW QUESTION # 31
In the next year, you expect the number of concurrent active users of your application to increase from approximately 50 to 500.
Which two recommendations for your Appian environment would address the performance risk of this large increase in users? (Choose two.)
- A. Switch from a records-centric to a process-centric design.
- B. Add more process execution engines.
- C. Add more application server memory.
- D. Add more design engines.
Answer: B,C
Explanation:
Explanation
The question is about the recommendations for Appian environment to address the performance risk of a large increase in users. The following are two recommendations for this purpose:
* Add more process execution engines. This means adding more servers or nodes that can execute process instances in parallel, which can improve the scalability and availability of Appian. This can help handle the increased workload and demand from more users without affecting the response time or reliability of Appian.
* Add more application server memory. This means increasing the amount of memory allocated to each server or node that runs Appian components, such as web servers, engines, or analytics servers. This can help improve the performance and stability of Appian by reducing memory pressure and garbage collection.
The following are not recommendations for Appian environment to address the performance risk of a large increase in users:
* Add more design engines. This means adding more servers or nodes that can execute expression rules or interface components in parallel, which can improve the performance and scalability of Appian.
However, this is not directly related to the number of users, but rather to the complexity and frequency of expression rules or interface components in the application.
* Switch from a records-centric to a process-centric design. This means changing the application design to focus more on process models and tasks, rather than records and reports. This does not affect the Appian environment, but rather the application logic and functionality. This may or may not improve the performance of the application, depending on the requirements and use cases.

NEW QUESTION # 36
Users are reporting that their application is slow to load customer records with many transactions.
Using performance monitoring tools, you find that the following interface definition is responsible for the vast majority of page load time:
You also notice that both queries (rule!APP_GetTransactionsWithFilters and rule!APP_GetTransactionTypeWithFilters) take about 25 milliseconds each to execute when you test them using expression editor.
Which change would decrease the load time of this interface component the most? (Choose the best answer.)
- A. Prefetched transation types and use the displayvalue() function to display the Transaction Type for each transaction.
- B. Use a synced record for Transactions to improve the query response time for the query performed on line 6.
- C. On line 4, increase the paginginfo batch size to 50 so more data is prefetched.
- D. Don't fetch total count when getting transactions.
Answer: A
Explanation:
Explanation
The load time of this interface component can be improved by reducing the number of queries performed and the amount of data transferred. One way to achieve this is to prefetch the transaction types and use the displayvalue() function to display the Transaction Type for each transaction. This way, only one query is performed to get the transactions, and the transaction types are retrieved from a local variable instead of a separate query. This reduces the network latency and the database load, which can improve the performance of the interface. Therefore, the best answer is D.

- A. logging.properties
- B. commons-logging.properties
- C. appian_log4j.properties
- D. custom.properties
Answer: C
NEW QUESTION # 38
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. Execute Count
- B. Transform Count
- C. Total Count
- D. Query Count
Answer: C
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 # 40
More than one user is editing the same record in database.
With XSD, how do you avoid the collision of data from Application? (Choose the best answer.)
- A. @OrderBy
- B. @inheritance
- C. @Version
- D. @AssociationOverrides
Answer: C
Explanation:
Explanation
The @Version annotation is used to avoid the collision of data from an application when more than one user is editing the same record in a database. The @Version annotation enables optimistic locking, which is a mechanism to detect and prevent concurrent updates on the same record. Optimistic locking assumes that multiple transactions can complete without affecting each other, and that therefore transactions do not need to lock data resources until they are ready to commit. However, if a transaction tries to commit changes to a record that has been modified by another transaction since it was last read, an OptimisticLockException is thrown and the transaction is rolled back. The @Version annotation can be applied to a field or property of a CDT that stores a numeric value. This value is used as a version number that is automatically incremented by Appian every time the record is updated. References: Does Appian support @Version JPA Annotation?, JPA

- A. When all case details are entered, the process flow will call a Sub-Process node to initialize a review process model for the reviewer.
- B. 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.
- C. When all case details are entered, the process flow will proceed and assign a task to the reviewer to review the record.
- D. When all case details are entered, the process flow will call a Start Process node to initialize a review process model for the reviewer.
Answer: B
NEW QUESTION # 42
Which user role should be used to allow external systems to invoke Appian web APIs?
- A. Application User
- B. Designer
- C. Service Account
- D. System Administrator
Answer: C
Explanation:
Explanation
The question is about allowing external systems to invoke Appian web APIs. A service account is the user role that should be used for this purpose, as it is a special type of basic user that can be configured to authenticate with web APIs using an API key. A service account can also be assigned to specific groups or roles to control the access to web APIs. The other options are not user roles, but rather groups or user types that are not suitable for this purpose. References:
* Service Accounts
* Web API Security
NEW QUESTION # 43
You are reviewing a recent Health Check report and notice that a process model has high memory consumption.
What are three possible reasons for this? (Choose three.)
- A. Too many nodes
- B. Misconfigured error alerts
- C. Gateway nodes with multiple incoming flows
- D. Too many process variables
- E. Nested CDTs with large numbers of fields
Answer: A,D,E
Explanation:
Explanation
Three possible reasons for high memory consumption of a process model are:
* Too many process variables. Process variables are used to store data that is needed throughout the process execution. However, having too many process variables can increase the memory usage of the process engine, especially if the variables store large or complex data types, such as documents or CDTs. It is recommended to use local variables whenever possible, and to delete or nullify process variables that are no longer needed.
* Nested CDTs with large numbers of fields. CDTs are custom data types that define the structure and validation of business data in Appian. CDTs can be nested within other CDTs to create complex data models. However, nesting CDTs with large numbers of fields can result in high memory consumption and performance degradation, as each field requires additional memory allocation and processing. It is recommended to limit the number of fields and nesting levels of CDTs, and to use references instead of embedding whenever possible.
* Too many nodes. Nodes are the graphical elements that represent the activities and events in a process model. Having too many nodes in a process model can increase the memory usage and complexity of the process execution. It can also make the process model harder to read and maintain. It is recommended to simplify the process model by using subprocesses, smart services, or expression rules to encapsulate common or reusable logic.

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. 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.
- D. A loop is created within the process model that increments on each iteration, updating that particular row in the data set.
Answer: B,C
