How should you scale a system with a high load average in ? - ANSWER Add Hardware - Usually CPU or RAM (vertical scaling) 2. How should you scale a system with high Java work queue size in the engine performance logs? - ANSWER Add Application Servers (horizontal scaling) 3. How should you scale a system with high other time in engine call summary log? - ANSWER Add Engine Replicas (horizontal scaling via read-only replicas) 4. What are HTTP and OpenAPI connected systems used for? - ANSWER Use these connected systems to generically connect to most API's. 5. What are Pre-Built connected systems used for? - ANSWER 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 4) DocuSign 5) Google Cloud Natural Language 6) Google Cloud Translation 7) Google Cloud Vision 8) Google Drive 9) Microsoft Azure LUIS 10) 11) 12) Microsoft Dynamics 365 Salesforce Sharepoint 6. What are Data Source connected systems used for? - ANSWER Use these connected systems to connect to Appian- supported databases. These databases include: 1) DB2 Data Source 2) MariaDB Data Source 3) MySQL Data Source 4) Oracle Data Source 5) PostgreSQL Data Source 6) SQL Server Data Source 7. What is the difference between OpenAPI connected systems and HTTP connected systems? - ANSWER OpenAPI connected systems are HTTP connected systems that leverage an OpenAPI document to inherit a base URL and authentication options. Additionally, they can use that OpenAPI document to display the list of included operations and generate integrations from them. These generated integrations will already include the path, rule inputs, query parameters, and HTTP headers specified by the OpenAPI document. 8. What is an OpenAPI/Swagger Document? - ANSWER An OpenAPI documents (formerly known as a Swagger document) defines a standard interface to a RESTful API. They can be read by a human or computer to understand the capabilities of a web service without access to source code/documentation. By uploading these to your connected system, Appian can inherit base URLs, authentication details, and a list of operations. 9. Describe the HTTP request method GET. - ANSWER The GET method requests a representation of the specified resource. Requests using GET should only retrieve data. 10. Describe the HTTP request method HEAD. - ANSWER The HEAD method asks for a response identical to a GET request, but without the response body. 11. How should you scale a system with low idle time in the engine performance logs? - ANSWER Add Execution and Analytics Shards (horizontal scaling via partitioning/sharding) 12. How should you scale a system with high execute time in perf_monitor_rdbmd_? - ANSWER Optimize Your Queries and Applications and External Data Sources 13. What are the key differences between a summary log and a detail log? - ANSWER 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. 14. 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. 15. What are some key factors developers should take into account because they will affect the memory footprint of a PROCESS? - ANSWER 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 16. What are the 8 best practices used to improve messaging efficiency? - ANSWER 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 17. What is a maintenance window? - ANSWER 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. 18. What are the three types of connected systems? - ANSWER 1) HTTP and Open API 2) Pre-Built 3) Data Source 19. Describe the HTTP request method POST. - ANSWER The POST method submits an entity to the specified resource, often causing a change in state or side effects on the server. 20. Describe the HTTP request method PUT. - ANSWER The PUT method replaces all current representations of the target resource with the request payload.
