Appian Senior Developer Exam 2025
How should you scale a system with a high load average in system.csv? - ✅✅✅CORRECT -Add
Hardware - Usually CPU or RAM (vertical scaling)
How should you scale a system with high Java work queue size in the engine performance logs? -
✅✅✅CORRECT -Add Application Servers (horizontal scaling)
How should you scale a system with high other time in engine call summary log? - ✅✅✅CORRECT -
Add Engine Replicas (horizontal scaling via read-only replicas)
How should you scale a system with low idle time in the engine performance logs? - ✅✅✅CORRECT
-Add Execution and Analytics Shards (horizontal scaling via partitioning/sharding)
How should you scale a system with high execute time in perf_monitor_rdbmd_slow.csv? -
✅✅✅CORRECT -Optimize Your Queries and Applications and External Data Sources
What are the key differences between a summary log and a detail log? - ✅✅✅CORRECT -Although
both are enabled by default, summary logs are written to once every five minutes and aggregate all the
relevant events since the last line was logged into one set set of metrics. Also one line is written per
update, even if there are no events in the given interval.
Detail logs are written to once every hour and they provide fine-grain aggregation by type of event.
Multiple lines can be written per update, but will only be written if events occurred.
What are some key factors developers should take into account because they will affect the memory
footprint of a PROCESS? - ✅✅✅CORRECT -All factors directly relate to completion time. Short lived
processes are best practice.
1) Size of process model (# of nodes)
2) Size and number of process variable
, 3) Looping
4) Number of active process instances
What are the 8 best practices used to improve messaging efficiency? - ✅✅✅CORRECT -1) Use
Conditional Filters
2) Target Processes by ID
3) Allow Public Events
4) Avoid Cascading Messages
5) Avoid Message Loops
6) Minimize the Number of Listeners
7) Pass Minimal Amounts of Data
8) Avoid Enabling the Activate Message Event
What is a maintenance window? - ✅✅✅CORRECT -The Maintenance Window page allows you to set
a period of time to deploy application updates to your environment and write a message to display in a
banner at the top of your site. During maintenance windows, all users except for system administrators
will be logged out of the site, and a banner will display at the top of your site's login page for web and
mobile.
What are the three types of connected systems? - ✅✅✅CORRECT -1) HTTP and OpenAPI
2) Pre-Built
3) Data Source
What are HTTP and OpenAPI connected systems used for? - ✅✅✅CORRECT -Use these connected
systems to generically connect to most API's.
What are Pre-Built connected systems used for? - ✅✅✅CORRECT -Use these connected systems to
connect to some of the most common integrations. These integrations include:
1) Amazon Machine Learning
2) Appian RPA
3) Blue Prism
