• Question 21:

  You are designing a process that is anticipated to be executed multiple times a day. This process retrieves data from an external system and then calls various utility processes as needed. The mam process will not use the results of the utility processes, and there are no user forms anywhere.

  Which design choice should be used to start the utility processes and minimize the load on the execution engines?

  A. Use the Start Process Smart Service to start the utility processes.

  B. Start the utility processes via a subprocess synchronously.

  C. Use Process Messaging lo star! the utility process.

  D. Start the utility processes via a subprocess asynchronously

  Correct Answer: C

  To design a process that is anticipated to be executed multiple times a day, that retrieves data from an external system and then calls various utility processes as needed, you should use Process Messaging to start the utility process and minimize the load on the execution engines. Process Messaging is a feature that allows you to send and receive messages between processes in Appian. By using Process Messaging, you can start the utility process asynchronously, which means that the main process does not have to wait for the utility process to finish before continuing. This way, you can improve the performance and scalability of your process design, and reduce the load on the execution engines. The other options are not as effective. Option A, using the Start Process Smart Service to start the utility processes, would also start the utility process asynchronously, but it would require more configuration and maintenance than Process Messaging. Option B, starting the utility processes via a subprocess synchronously, would start the utility process as a part of the main process flow, which means that the main process would have to wait for the utility process to finish before continuing. This would reduce the performance and scalability of your process design, and increase the load on the execution engines. Option D, starting the utility processes via a subprocess asynchronously, would also start the utility process as a part of the main process flow,but it would not wait for the utility process to finish before continuing. However, this option would still create more overhead than Process Messaging, as it would create more instances of processes in Appian.

• Question 22:

  You have an active development team (Team A) building enhancements for an application (App X'). and ate currently using the TEST environment for UAT.

  A separate operations team ('Team B) discovers a critical error in the Production instance of App X that they must remediate However. Team 6 does not have a hotfix stream for which to accomplish this The available environments are DEV. TEST, and PROD

  Which risk mitigation effort should both teams employ to ensure Team AS capital project is only minorly interrupted, and Team B s critical fix can be completed and deployed quickly to end users?

  A. Team 8 must communicate to Team A which component will be addressed in the hotfix to avoid overlap of changes It overlap exists, the component must be versioned to its PROD state before being remediated and deployed, and then versioned back to its latest development state If overlap does not exist, the component may be remediated and deployed without any version changes

  B. Team A must analyze their current codebase in OEV lo merge the hotfix changes into their latest enhancements. Team B is then requited to wait for the hotfix to follow regular deployment protocols from DEV to the PROO environment.

  C. Team 8 must address changes in the TEST environment These changes can then be tested and deployed directly to PROD. Once the deployment is complete. Team B can then communicate their changes to Teams to ensure they are Incorporated as a part of the next release.

  D. Team 8 must address the changes directly in PROD. As there is no hotfix stream, and OEV and TEST are being utilized for active development it is best to avoid a conflict of components. Once Team A has completed their enhancements work. Team 6 can update DEV and TEST accordingly.

  Correct Answer: A

  This is the best risk mitigation effort that both teams can employ to ensure that Team A's capital project is only minorly interrupted, and Team B's critical fix can be completed and deployed quickly to end users. By communicating with Team A, Team B can identify which component is causing the critical error in PROD, and check if there is any overlap of changes with Team A's enhancements. If there is an overlap, Team B can version the component to its PROD state, which is the last stable version, before making any changes to fix the error. Then, Team B can deploy the fixed component to PROD, and version it back to its latest development state, which includes Team A's enhancements. This way, Team B can avoid overwriting or losing any of Team A's work, and ensure that the component is consistent across all environments. If there is no overlap, Team B can simply make the changes to the component and deploy it to PROD, without affecting Team A's work. The other options are not as effective. Option B, having Team A analyze their current codebase in DEV to merge the hotfix changes into their latest enhancements, would delay the deployment of the critical fix, as Team B would have to wait for Team A to finish their analysis and merge. Option C, having Team B address the changes in TEST, would interrupt Team A's UAT process, and could cause conflicts or errors in TEST or PROD. Option D, having Team B address the changes directly in PROD, would be risky and not recommended, as it could introduce new errors or inconsistencies in PROD.

• Question 23:

  You are on a protect with an application that has been deployed to Production and is live with users. The client wishes to increase the number of active users.

  You need to conduct load testing to ensure Production can handle the increased usage

  Review the specs for four environments in the following image.

  

  Which environment should you use for load testing7

  A. acmeuat

  B. acmedev

  C. acme

  D. acmetest

  Correct Answer: C

  The best environment to use for load testing is acme, which is the production environment. This is because load testing should be performed on an environment that is as close as possible to the actual production environment, in terms of hardware, software, configuration, data, and user behavior. This way, the results of the load testing will be more realistic and reliable, and can help to identify and resolve any performance issues or bottlenecks before increasing the number of active users.

• Question 24:

  You are taskedto build a large scale acquisition application for a prominent customer. The acquisition process tracks the time it takes is fulfill a purchase request with an award.

  The customer has structured the contract so that there are multiple application dev teams.

  How should you design for multiple processes and forms, while minimizing repeated code?

  A. Create a Center of Excellence (CoE)

  B. Create a common objects application.

  C. Create a Scrum of Scrums sprint meeting for the team leads

  D. Create duplicate processes and forms as needed

  Correct Answer: B

  To build a large scale acquisition application for a prominent customer, you should design for multiple processes and forms, while minimizing repeated code. One way to do this is to create a common objects application, which is a shared application that contains reusable components, such as rules, constants, interfaces, integrations, or data types, that can be used by multiple applications. This way, you can avoid duplication and inconsistency of code, and make it easier to maintain and update your applications. You can also use the common objects application to define common standards and best practices for your application development teams, such as naming conventions, coding styles, or documentation guidelines.

• Question 25:

  Your Agile Scrum project requires you to manage two teams, with three developers per team. Both teams are to work on the same application In parallel.

  How should the work be divided between the teams, avoiding issues caused by cross- dependency?

  A. Group epics and stones by technical difficulty, and allocate one team the more challenging stories

  B. Group epics and stones by feature, and allocate work between each team by feature.

  C. Allocate stories to each team based on the cumulative years of experience of the team members.

  D. Have each team choose the stones they would like to work on based on personal preference

  Correct Answer: B

  The best way to divide the work between the teams, avoiding issues caused by cross-dependency, is to group epics and stories by feature, and allocate work between each team by feature. This way, each team can focus on a specific feature and minimize the need for coordination or integration with the other team. This also reduces the risk of conflicts or errors when merging the code from both teams. Verified References: Appian Documentation, section "Agile Development".

• Question 26:

  You are running an inspection as a part of the first deployment process from TEST to PROD. You receive a notice that one of your objects will not deploy because it is dependent on an object from an application owned by a separate team.

  What should be your next step?

  A. Create your own object with the same code base, replace (he dependent object in the application. and deploy to PROO.

  B. Halt the production deployment and contact the other team tor guidance on promoting the object to PROD

  C. Check the dependencies of the necessary object Deploy w PROO if there are few dependencies and it is low risk

  D. Push a functionally viable package to PROD without the dependencies, and plan the rest o! the deployment accordingly with the other team's constraints

  Correct Answer: B

  Deploying an object that is dependent on another object from a different application can cause errors and inconsistencies in the production environment. The best practice is to halt the production deployment and contact the other team for guidance on how to promote the object to PROD. The other team may have a different deployment schedule, or they may have some dependencies or customizations that need to be considered. By communicating with the other team, you can ensure that the object is deployed in a safe and coordinated manner, and avoid any potential conflicts or issues.

• Question 27:

  You add an index on the searched field of a MySQL table with many rows (>100k).

  The field would benefit greatly from the Index in which three scenarios?

  A. The field contains a textual shot Business code.

  B. The field contains long unstructured text such as a hash

  C. The field contains many datetimes, covering a large range

  D. The Add contains Dig integers, above and below 0.

  E. The field contains a structured JSON.

  Correct Answer: ACD

  The field would benefit greatly from the index in the following scenarios:

  A. The field contains a textual short Business code. This is a scenario where an index can improve the performance of queries that search for exact matches or ranges of values in the field. A textual short Business code is likely to have high

  cardinality, meaning that it has many distinct values and low duplication. This makes the index more selective and efficient, as it can quickly narrow down the results based on the search criteria.

  C. The field contains many datetimes, covering a large range. This is a scenario where an index can improve the performance of queries that search for exact matches or ranges of values in the field. A datetime field is likely to have high

  cardinality, meaning that it has many distinct values and low duplication. This makes the index more selective and efficient, as it can quickly narrow down the results based on the search criteria.

  D. The field contains big integers, above and below 0. This is a scenario where an index can improve the performance of queries that search for exact matches or ranges of values in the field. A big integer field is likely to have high cardinality,

  meaning that it has many distinct values and low duplication. This makes the index more selective and efficient, as it can quickly narrow down the results based on the search criteria.

  The other options are incorrect for the following reasons:

  B. The field contains long unstructured text such as a hash. This is a scenario where an index might not improve the performance of queries that search for exact matches or ranges of values in the field. A long unstructured text field is likely to

  have low cardinality, meaning that it has few distinct values and high duplication. This makes the index less selective and efficient, as it cannot quickly narrow down the results based on the search criteria. Moreover, indexing a long

  unstructured text field could increase thestorage space and maintenance cost for the database, which could affect the overall performance.

  E. The field contains a structured JSON. This is a scenario where an index might not improve the performance of queries that search for exact matches or ranges of values in the field. A structured JSON field is not a native data type in

  MySQL, and it requires special functions or operators to access or manipulate its elements. Indexing a structured JSON field could increase the complexity and overhead for the database, which could affect the overall performance. Verified

• Question 28:

  What are two advantages of having High Availability (HA) for Applan Cloud applications?

  A. An Applan Cloud HA instance is composed of multiple active nodes running in different availability zones in differentregions.

  B. Data andtransactions are continuouslyreplicated across the active nodes to achieve redundancy and avoid single points offailure.

  C. A typical Appian Cloud HA instance is composed of two active nodes.

  D. In the event of a system failure, your Appian instance will fie restored and available to your users in less than 15 minutes.having lost no more than the last 1minute worth of data.

  Correct Answer: BD

  The two advantages of having High Availability (HA) for Appian Cloud applications are:

  B. Data and transactions are continuously replicated across the active nodes to achieve redundancy and avoid single points of failure. This is an advantage of having HA, as it ensures that there is always a backup copy of data and transactions in case one of the nodes fails or becomes unavailable. This also improves data integrity and consistency across the nodes, as any changes made to one node are automatically propagated to the other node. D. In the event of a system failure, your Appian instance will be restored and available to your users in less than 15 minutes, having lost no more than the last 1 minute worth of data. This is an advantage of having HA, as it guarantees a high level of service availability and reliability for your Appian instance. If one of the nodes fails or becomes unavailable, the other node will take over and continue to serve requests without any noticeable downtime or data loss for your users. The other options are incorrect for the following reasons:

  A. An Appian Cloud HA instance is composed of multiple active nodes running in different availability zones in different regions. This is not an advantage of having HA, but rather a description of how HA works in Appian Cloud. An Appian Cloud HA instanceconsists of two active nodes running in different availability zones within the same region, not different regions.

  C. A typical Appian Cloud HA instance is composed of two active nodes. This is not an advantage of having HA, but rather a description of how HA works in Appian Cloud. A typical Appian Cloud HA instance consists of two active nodes running in different availability zones within the same region, but this does not necessarily provide any benefit over having one active node.

• Question 29:

  You are developing a case management application to manage support cases for a large set of sites. One of the tabs in this application s site Is a record grid of cases, along with Information about the site corresponding to that case. Users must be able to filter cases by priority level and status.

  You decide to create a view as the source of your entity-backed record, which joins the separate case/site tables (as depicted in the following Image).

  

  Which three column should be indexed?

  A. site_id

  B. status

  C. name

  D. modified_date

  E. priority

  F. case_id

  Correct Answer: ABE

  Indexing columns can improve the performance of queries that use those columns in filters, joins, or order by clauses. In this case, the columns that should be indexed are site_id, status, and priority, because they are used for filtering or joining the tables. Site_id is used to join the case and site tables, so indexing it will speed up the join operation. Status and priority are used to filter the cases by the user's input, so indexing them will reduce the number of rows that need to be scanned. Name, modified_date, and case_id do not need to be indexed, because they are not used for filtering or joining. Name and modified_date are only used for displaying information in the record grid, and case_id is only used as a unique identifier for each record.

• Question 30:

  You are presented with the following application requirement:

  Users must be able to navigate throughout the application while maintaining complete visibility in the

  application structure, and easily navigate to previous locations.''

  Which Appian Interface Pattern would you recommend?

  A. Use Bullous as Cards pattern on the home page lo prominently display application choices.

  B. Implement an Activity History pattern to track an organizations activity measures.

  C. implement a drilldown report pattern to show detailed information about report data.

  D. Include a breadcrumbs pattern on applicable inert aces to show the organizational hierarchy

  Correct Answer: C

  To meet the application requirement of allowing users to view summary and detailed information about report data, you should implement a drilldown report pattern to show detailed information about report data. A drilldown report pattern is a user interface component that displays data in a hierarchical structure, and allows users to expand or collapse different levels of data. For example, if the user is viewing a sales report by region, the drilldown report pattern could show something like "North America > USA > California > Los Angeles". The user can click on any level of data to see more or less details. This way, the user can see both summary and detailed information about report data, and explore different aspects of the data. The other options are not as effective. Option A, using Tiles as Cards pattern on the home page to prominently display application choices, would provide a way for users to access different parts of the application from the home page, but it would not show summary or detailed information about report data. Option B, implementing an Activity History pattern to track an organization's activity measures, would provide a way for users to see the recent actions performed by themselves or others in the application, but it would not show summary or detailed information about report data. Option D, including a breadcrumbs pattern on applicable interfaces to show the organizational hierarchy, would provide a way for users to see where they are in the application, and easily go back to any previous level by clicking on the corresponding link, but it would not show summary or detailed information about report data.
