As a Lead System Architect at a multinational corporation, you are tasked with addressing significant user- reported delays in a critical application. Suspecting that the delays are due to database-related issues that have arisen suddenly, you aim to identify and resolve the problem methodically. Which two options do you recommend to isolate the issue and enhance performance? (Choose Two)

• A. Analyze the periods during which the database experiences the highest usage, because this method assists in pinpointing the specific times to search for alerts or other issues in the log files.
• B. Reduce the thresholds for query-time alerts to more easily identify complex queries that might be causing delays.
• C. Configure the system to write Pega logs to the database server to gain insights into the events occurring within the application that might contribute to the delays.
• D. Raise the threshold for blob-size alerts to aid in the detection of large case instances that might impact performance.

As the lead for Pega projects, you are assigned the task of creating a quarterly performance review report for an organization's marketing department. The report should encompass various aspects of their work, such as campaign effectiveness, budget utilization, and team productivity. However, there is a request for detailed data on individual campaigns while maintaining a comprehensive summary of departmental performance.
Which of the following is the best reporting design approach for this requirement?

• A. Create a summary report for the marketing department to show overall performance and a drill-down report containing detailed data on each campaign.
• B. Create individual reports for each campaign to ensure detailed analysis, and then a consolidated report for a summary.
• C. Create a report for every quarter with detailed data and then create a yearly report to show the summary of performance of campaigns.
• D. Create a report that includes all detailed campaign data within the main report to maintain a comprehensive overview of departmental performance.

What is the best approach for implementing limited-availability-and-concurrency design patterns?

• A. Manage the limited resources by using the lock on the instance (data or case); once locked, Pega Platform automatically manages the concurrency.
• B. Use a data instance approach to represent each incoming request for consuming limited available resources. Handle requests with flags to manage resource locks and availability. Processing techniques in Pega Platform manage concurrency.
• C. Create a case instance for each request that represents consuming limited available resources. Case management features in Pega Platform automatically manage locks and concurrency.
• D. Circumstance the rule resolution algorithm to fit the requirements of the business use case; Pega Platform automatically manages the limited availability and concurrency.

Dynamic class references (DCR) are one approach to creating a data model in a Pega implementation. Which one of the following best describes the DCR approach?

• A. Referencing classes that are predefined and unchangeable, ensuring consistency and reliability in the data model.
• B. Associating objects with classes at runtime based on user input or certain conditions, allowing for flexibility in the structure of the data model.
• C. Linking different classes together in a data model to establish relationships and associations between various entities.
• D. Dynamically adjusting the attributes of a class without modifying its structure, facilitating agile data management.

A Pega Platform application designed for customer onboarding in a bank involves multiple subprocesses and extensive data entry and retrieval. With over 15 screens to navigate, the Quality Assurance team faces challenges in thoroughly testing the application. Each bug fix requires the team to restart testing from the beginning, adding to the difficulty. What suggestion do you adopt as a Lead System Architect to assist the team?

• A. Advise the team to create Pega test suites to run the bulk test cases in one go and speed up the testing process.
• B. Advise the team to begin recording the testing performed using the scenario testing feature, and then replay the recording when testing the application after performing bug fixes.
• C. Suggest that the team begins recording with the screen recording feature of the browser, and then replay the recording when testing the application after performing bug fixes.
• D. Encourage the team to write utilities to speed up the testing process.
