Advance Level CTAL-TTA Syllabus Exam Questions Answers

Analysis:

To determine the correct keyword-driven input table for testing the enhancement to the social media application, we need to ensure the table adequately covers the following scenarios:

Adding existing members to a group.

Attempting to add non-existing members to a group and handling the error.

Removing members from a group.

Deleting groups only if no members are attached.

A. (Image A) - Assuming Image A correctly represents these scenarios.

Adding Members: The table should include steps to add both valid (existing) and invalid (non-existing) members to a group, ensuring the application correctly handles both scenarios.

Removing Members: The table should include steps to remove members from a group.

Deleting Groups: The table should include a scenario where a group with no members is deleted successfully.

Analysis:

For Change 1, which involves using multiple servers to maximize throughput and minimize response time, the key concern is how the load is distributed across these servers.

B. Load balancing:

Load balancing is the process of distributing network or application traffic across multiple servers to ensure no single server becomes overwhelmed. It is crucial for maximizing throughput and minimizing response times, particularly during peak volumes.

Explanation of Incorrect Options:

A. Connection pooling:

This is related to managing database connections efficiently but is not directly relevant to distributing web server traffic.

C. Distributed processing:

This refers to dividing processing tasks across multiple processors or machines but is not specific to managing web server load.

D. Caching:

Caching helps improve performance by storing frequently accessed data in memory, reducing the need to retrieve it from the database, but it does not address load distribution across servers.

The comment frequency in a code fragment relates to the number of comments in relation to the code size. A good level of comment frequency can significantly contribute to the maintainability of the software. Maintainability is a non-functional quality characteristic that refers to the ease with which a software system can be modified to correct defects, update features, improve performance or other attributes, or adapt to a changed environment. Comments in the code help developers understand the logic, purpose, and functionality of the code, which is crucial when modifications are required. This does not directly contribute to portability, usability, or performance efficiency, which are concerned with different aspects of the software's operation and user interaction.

The most likely pair of requirements engineering techniques used to uncover the issues mentioned with the user story would be "Storyboards and Personas." This approach allows for a visual and persona-based exploration of how different users (such as drivers of different vehicle types and disabled drivers) would interact with the system. This technique helps in uncovering varied user needs and ensuring that all critical user interactions are considered during the development process​​.
