Appian Lead Developer Sample Questions (Q13-Q18):

NEW QUESTION # 13
On the latest Health Check report from your Cloud TEST environment utilizing a MongoDB add-on, you note the following findings:
Category: User Experience, Description: # of slow query rules, Risk: High Category: User Experience, Description: # of slow write to data store nodes, Risk: High Which three things might you do to address this, without consulting the business?

  • A. Optimize the database execution. Replace the view with a materialized view.
  • B. Reduce the size and complexity of the inputs. If you are passing in a list, consider whether the data model can be redesigned to pass single values instead.
  • C. Reduce the batch size for database queues to 10.
  • D. Optimize the database execution using standard database performance troubleshooting methods and tools (such as query execution plans).
  • E. Use smaller CDTs or limit the fields selected in a!queryEntity().

Answer: B,D,E

Explanation:
Comprehensive and Detailed In-Depth Explanation:The Health Check report indicates high-risk issues with slow query rules and slow writes to data store nodes in a MongoDB-integrated Appian Cloud TEST environment. As a Lead Developer, you can address these performance bottlenecks without business consultation by focusing on technical optimizations within Appian and MongoDB. The goal is to improve user experience by reducing query and write latency.
* Option B (Optimize the database execution using standard database performance troubleshooting methods and tools (such as query execution plans)):This is a critical step. Slow queries and writes suggest inefficient database operations. Using MongoDB's explain() or equivalent tools to analyze execution plans can identify missing indices, suboptimal queries, or full collection scans. Appian's Performance Tuning Guide recommends optimizing database interactions by adding indices on frequently queried fields or rewriting queries (e.g., using projections to limit returned data). This directly addresses both slow queries and writes without business input.
* Option C (Reduce the size and complexity of the inputs. If you are passing in a list, consider whether the data model can be redesigned to pass single values instead):Large or complex inputs (e.
g., large arrays in a!queryEntity() or write operations) can overwhelm MongoDB, especially in Appian' s data store integration. Redesigning the data model to handle single values or smaller batches reduces processing overhead. Appian's Best Practices for Data Store Design suggest normalizing data or breaking down lists into manageable units, which can mitigate slow writes and improve query performance without requiring business approval.
* Option E (Use smaller CDTs or limit the fields selected in a!queryEntity()):Appian Custom Data Types (CDTs) and a!queryEntity() calls that return excessive fields can increase data transfer and processing time, contributing to slow queries. Limiting fields to only those needed (e.g., using fetchTotalCount selectively) or using smaller CDTs reduces the load on MongoDB and Appian's engine. This optimization is a technical adjustment within the developer's control, aligning with Appian' s Query Optimization Guidelines.
* Option A (Reduce the batch size for database queues to 10):While adjusting batch sizes can help with write performance, reducing it to 10 without analysis might not address the root cause and could slow down legitimate operations. This requires testing and potentially business input on acceptable performance trade-offs, making it less immediate.
* Option D (Optimize the database execution. Replace the view with a materialized view):
Materialized views are not natively supported in MongoDB (unlike relational databases like PostgreSQL), and Appian's MongoDB add-on relies on collection-based storage. Implementing this would require significant redesign or custom aggregation pipelines, which may exceed the scope of a unilateral technical fix and could impact business logic.
These three actions (B, C, E) leverage Appian and MongoDB optimization techniques, addressing both query and write performance without altering business requirements or processes.
References:Appian Documentation - Performance Tuning Guide, Appian MongoDB Add-on Best Practices, Appian Lead Developer Training - Query and Write Optimization.
The three things that might help to address the findings of the Health Check report are:
* B. Optimize the database execution using standard database performance troubleshooting methods and tools (such as query execution plans). This can help to identify and eliminate any bottlenecks or inefficiencies in the database queries that are causing slow query rules or slow write to data store nodes.
* C. Reduce the size and complexity of the inputs. If you are passing in a list, consider whether the data model can be redesigned to pass single values instead. This can help to reduce the amount of data that needs to be transferred or processed by the database, which can improve the performance and speed of the queries or writes.
* E. Use smaller CDTs or limit the fields selected in a!queryEntity(). This can help to reduce the amount of data that is returned by the queries, which can improve the performance and speed of the rules that use them.
The other options are incorrect for the following reasons:
* A. Reduce the batch size for database queues to 10. This might not help to address the findings, as reducing the batch size could increase the number of transactions and overhead for the database, which could worsen the performance and speed of the queries or writes.
* D. Optimize the database execution. Replace the new with a materialized view. This might not help to address the findings, as replacing a view with a materialized view could increase the storage space and maintenance cost for the database, which could affect the performance and speed of the queries or writes.

NEW QUESTION # 14
You are running an inspection as 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 the dependent object in the application, and deploy to PROD.
  • B. Halt the production deployment and contact the other team for guidance on promoting the object to PROD.
  • C. Check the dependencies of the necessary object. Deploy to PROD 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 of the deployment accordingly with the other team's constraints.

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:As an Appian Lead Developer, managing a deployment from TEST to PROD requires careful handling of dependencies, especially when objects from another team's application are involved. The scenario describes a dependency issue during deployment, signaling a need for collaboration and governance. Let's evaluate each option:
* A. Create your own object with the same code base, replace the dependent object in the application, and deploy to PROD:This approach involves duplicating the object, which introduces redundancy, maintenance risks, and potential version control issues. It violates Appian's governance principles, as objects should be owned and managed by their respective teams to ensure consistency and avoid conflicts. Appian's deployment best practices discourage duplicating objects unless absolutely necessary, making this an unsustainable and risky solution.
* B. Halt the production deployment and contact the other team for guidance on promoting the object to PROD:This is the correct step. When an object from another application (owned by a separate team) is a dependency, Appian's deployment process requires coordination to ensure both applications' objects are deployed in sync. Halting the deployment prevents partial deployments that could break functionality, and contacting the other team aligns with Appian's collaboration and governance guidelines. The other team can provide the necessary object version, adjust their deployment timeline, or resolve the dependency, ensuring a stable PROD environment.
* C. Check the dependencies of the necessary object. Deploy to PROD if there are few dependencies and it is low risk:This approach risks deploying an incomplete or unstable application if the dependency isn' t fully resolved. Even with "few dependencies" and "low risk," deploying without the other team's object could lead to runtime errors or broken functionality in PROD. Appian's documentation emphasizes thorough dependency management during deployment, requiring all objects (including those from other applications) to be promoted together, making this risky and not recommended.
* D. Push a functionally viable package to PROD without the dependencies, and plan the rest of the deployment accordingly with the other team's constraints:Deploying without dependencies creates an incomplete solution, potentially leaving the application non-functional or unstable in PROD. Appian's deployment process ensures all dependencies are included to maintain application integrity, and partial deployments are discouraged unless explicitly planned (e.g., phased rollouts). This option delays resolution and increases risk, contradicting Appian's best practices for Production stability.
Conclusion: Halting the production deployment and contacting the other team for guidance (B) is the next step. It ensures proper collaboration, aligns with Appian's governance model, and prevents deployment errors, providing a safe and effective resolution.

NEW QUESTION # 15
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. status
  • B. name
  • C. modified_date
  • D. site_id
  • E. case_id
  • F. priority

Answer: A,D,F

Explanation:
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.
Verified References: Appian Records Tutorial, Appian Best Practices
As an Appian Lead Developer, optimizing a database view for an entity-backed record grid requires indexing columns frequently used in queries, particularly for filtering and joining. The scenario involves a record grid displaying cases with site information, filtered by "priority level" and "status," and joined via the site_id foreign key. The image shows two tables (site and case) with a relationship via site_id. Let's evaluate each column based on Appian's performance best practices and query patterns:
* A. site_id:This is a primary key in the site table and a foreign key in the case table, used for joining the tables in the view. Indexing site_id in the case table (and ensuring it's indexed in site as a PK) optimizes JOIN operations, reducing query execution time for the record grid. Appian's documentation recommends indexing foreign keys in large datasets to improve query performance, especially for entity-backed records. This is critical for the join and must be included.
* B. status:Users filter cases by "status" (a varchar column in the case table). Indexing status speeds up filtering queries (e.g., WHERE status = 'Open') in the record grid, particularly with large datasets.
Appian emphasizes indexing columns used in WHERE clauses or filters to enhance performance, making this a key column for optimization. Since status is a common filter, it's essential.
* C. name:This is a varchar column in the site table, likely used for display (e.g., site name in the grid).
However, the scenario doesn't mention filtering or sorting by name, and it's not part of the join or required filters. Indexing name could improve searches if used, but it's not a priority given the focus on priority and status filters. Appian advises indexing only frequently queried or filtered columns to avoid unnecessary overhead, so this isn't necessary here.
* D. modified_date:This is a date column in the case table, tracking when cases were last updated. While useful for sorting or historical queries, the scenario doesn't specify filtering or sorting by modified_date in the record grid. Indexing it could help if used, but it's not critical for the current requirements.
Appian's performance guidelines prioritize indexing columns in active filters, making this lower priority than site_id, status, and priority.
* E. priority:Users filter cases by "priority level" (a varchar column in the case table). Indexing priority optimizes filtering queries (e.g., WHERE priority = 'High') in the record grid, similar to status. Appian' s documentation highlights indexing columns used in WHERE clauses for entity-backed records, especially with large datasets. Since priority is a specified filter, it's essential to include.
* F. case_id:This is the primary key in the case table, already indexed by default (as PKs are automatically indexed in most databases). Indexing it again is redundant and unnecessary, as Appian's Data Store configuration relies on PKs for unique identification but doesn't require additional indexing for performance in this context. The focus is on join and filter columns, not the PK itself.
Conclusion: The three columns to index are A (site_id), B (status), and E (priority). These optimize the JOIN (site_id) and filter performance (status, priority) for the record grid, aligning with Appian's recommendations for entity-backed records and large datasets. Indexing these columns ensures efficient querying for user filters, critical for the application's performance.

NEW QUESTION # 16
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!timezone reflect?

  • A. The time zone of the user who is completing the input task.
  • B. The default time zone for the environment as specified in the Administration Console.
  • C. The time zone of the server where Appian is installed.
  • D. The time zone of the user who most recently published the process model.

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:In Appian, the pm!timezone variable is a process variable automatically available in process models, reflecting the time zone context for scheduled or time- based operations. Understanding its behavior is critical for scheduling tasks accurately, especially in scenarios like this where a process runs daily and assigns a user input task.
* Option C (The default time zone for the environment as specified in the Administration Console):
This is the correct answer. Per Appian's Process Model documentation, when a process model uses pm!
timezone and no custom time zone is explicitly set, it defaults to the environment's time zone configured in the Administration Console (under System > Time Zone settings). For scheduled processes, such as one running "daily at a certain time," Appian uses this default time zone to determine when the process triggers. In this case, the task assignment occurs based on the schedule, and pm!
timezone reflects the environment's setting, not the user's location.
* Option A (The time zone of the server where Appian is installed):This is incorrect. While the server' s time zone might influence underlying system operations, Appian abstracts this through the Administration Console's time zone setting. The pm!timezone variable aligns with the configured environment time zone, not the raw server setting.
* Option B (The time zone of the user who most recently published the process model):This is irrelevant. Publishing a process model does not tie pm!timezone to the publisher's time zone. Appian's scheduling is system-driven, not user-driven in this context.
* Option D (The time zone of the user who is completing the input task):This is also incorrect. While Appian can adjust task display times in the user interface to the assigned user's time zone (based on their profile settings), the pm!timezone in the process model reflects the environment's default time zone for scheduling purposes, not the assignee's.
For example, if the Administration Console is set to EST (Eastern Standard Time), the process will trigger daily at the specified time in EST, regardless of the assigned user's location. The "1st time zone" phrasing in the question appears to be a typo or miscommunication, but it doesn't change the fact that pm!timezone defaults to the environment setting.

NEW QUESTION # 17
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 Billboards as Cards pattern on the homepage to prominently display application choices.
  • B. Implement an Activity History pattern to track an organization's activity measures.
  • C. Implement a Drilldown Report pattern to show detailed information about report data.
  • D. Include a Breadcrumbs pattern on applicable interfaces to show the organizational hierarchy.

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:The requirement emphasizes navigation with complete visibility of the application structure and the ability to return to previous locations easily. TheBreadcrumbs patternis specifically designed to meet this need. According to Appian's design best practices, the Breadcrumbs pattern provides a visual trail of the user's navigation path, showing the hierarchy of pages or sections within the application. This allows users to understand their current location relative to the overall structure and quickly navigate back to previous levels by clicking on the breadcrumb links.
* Option A (Billboards as Cards):This pattern is useful for presenting high-level options or choices on a homepage in a visually appealing way. However, it does not address navigation visibility or the ability to return to previous locations, making it irrelevant to the requirement.
* Option B (Activity History):This pattern tracks and displays a log of activities or actions within the application, typically for auditing or monitoring purposes. It does not enhance navigation or provide visibility into the application structure.
* Option C (Drilldown Report):This pattern allows users to explore detailed data within reports by drilling into specific records. While it supports navigation within data, it is not designed for general application navigation or maintaining structural visibility.
* Option D (Breadcrumbs):This is the correct choice as it directly aligns with the requirement. Per Appian's Interface Patterns documentation, Breadcrumbs improve usability by showing ahierarchical path (e.g., Home > Section > Subsection) and enabling backtracking, fulfilling both visibility and navigation needs.
