Qlik QSBA2024 Exam - Topic 3 Question 10 Discussion

Actual exam question for Qlik's QSBA2024 exam
Question #: 10
Topic #: 3
[All QSBA2024 Questions]

Exhibit.

Refer to the exhibit.

An app is being developed at a university to monitor student exam attempts- Three core tables are loaded into the app for Students, Exams, and Attempts. Students can attempt the same exam multiple times.

Before building any visualizations, the business analyst needs to know:

* How many students are in the system

* What percentage of students have not yet attempted an exam

Which metadata should the analyst focus on to answer these questions?

Show Suggested Answer Hide Answer
Suggested Answer: B

To meet the needs of both the internal analyst team and the sales team, the best solution is to create two separate apps: one designed specifically for mobile use and another for internal use. Mobile devices require different UI considerations, such as simpler, touch-optimized layouts, while the internal team can benefit from a more detailed app optimized for desktop use. Designing separate apps ensures that both teams have a tailored experience that suits their specific devices and use cases.

Key Concepts:

Mobile Optimization: Mobile devices require apps that are streamlined and optimized for smaller screens, while internal users on desktop computers can handle more complex layouts and detailed reports.

Separate Apps: Creating separate apps ensures that each team gets the best user experience tailored to their needs.

Why the Other Options Are Less Suitable:

A . One app with a specific extension for mobile users: While extensions can provide some mobile functionality, they don't offer the flexibility and optimization needed for a fully mobile-friendly experience.

C . A mashup with various objects: A mashup may provide flexibility, but it could be overly complex for this requirement and wouldn't necessarily offer an optimal mobile experience.

D . One app with various objects: This could complicate the user experience for both teams, as mobile users may struggle with objects that are not optimized for their devices.

References for Qlik Sense Business Analyst:

Mobile vs. Desktop App Design: Qlik Sense recommends optimizing apps for specific devices to ensure the best user experience for both desktop and mobile users.

Thus, B is the correct answer because it provides the best solution for both the mobile sales team and the internal analyst team, making it the verified answer.

I feel like option B is the best choice since it mentions non-null values, which could help us determine how many students haven't attempted anything yet.

I'm a bit confused. Shouldn't we be looking at the Attempts table for the StudentID? I feel like that might help us understand attempts better.

I remember a similar question where we had to look at distinct values in a table. It seems like option B makes sense for both parts of the question.

I think we need to focus on the Students table to find out how many students are in the system, but I'm not sure about the percentage of those who haven't attempted an exam.

Yeah, I agree with Emily. The question is asking about the metadata we need to answer the specific questions, so we should be looking at the Students table first to get the total student count, and then the Attempts table to see what percentage haven't tried any exams.

Okay, let me think this through. I believe the correct answer is B - we need to look at the non-null values and subset ratio for the StudentID field in the Students table to get the total number of students, and then compare that to the number of students who have attempted exams in the Attempts table.

Hmm, I'm a bit confused. Do we need to look at the Attempts table to get the total number of students, or should we be focusing on the Students table instead?

This seems straightforward - I think the key is to focus on the StudentID field across the tables to get the total number of students and the percentage who haven't attempted any exams.

Option B is the way to go, my dude. The number of students and the percentage who haven't attempted an exam are both gonna be in the Students table. Easy peasy, lemon squeezy!

This is a tricky one, but I reckon the answer is B. The business analyst needs to focus on the StudentID field in the Students table to get the total number of students and the percentage who haven't attempted an exam.

I think the key is to look at the Attempts table and see how many distinct StudentIDs there are. That will give us the total number of students. Then we can calculate the percentage of students who haven't attempted an exam by looking at the subset ratio.

The number of students and the percentage of students who haven't attempted an exam can be found by looking at the StudentID field in the Students table. The metadata to focus on would be the non-null values and the subset ratio.
