DL Advanced and Specialized Skills 2 — Questions and Answers
Question 1: A company wants to automate repetitive data entry tasks across multiple web forms. Which advanced technique is most appropriate?
- Using a macro-enabled spreadsheet only
- Robotic Process Automation (RPA) (Correct answer)
- Manually scripting each form individually
- Downloading all forms as PDFs
Correct answer: Robotic Process Automation (RPA)
RPA uses software bots to mimic human interactions with UIs, making it ideal for automating repetitive web-based data entry tasks.
Question 2: When working with large datasets in Python, which library is specifically optimized for high-performance data manipulation and analysis?
- Matplotlib
- Requests
- Pandas (Correct answer)
- BeautifulSoup
Correct answer: Pandas
Pandas provides fast, flexible data structures and operations designed for large-scale data manipulation and analysis in Python.
Question 3: A developer needs to expose application functionality to third-party developers in a standardized way. What is the best architectural approach?
- Sharing the entire source code
- Building a RESTful API (Correct answer)
- Sending data via email attachments
- Publishing a desktop installer
Correct answer: Building a RESTful API
A RESTful API provides a standardized, stateless interface that allows third-party applications to interact with functionality over HTTP.
Question 4: Which version control strategy allows teams to work on isolated features without disrupting the main codebase until they are ready to merge?
- Committing directly to main
- Using feature branches (Correct answer)
- Emailing code diffs
- Storing backups on a USB drive
Correct answer: Using feature branches
Feature branches in Git let developers work independently on new features and merge only when the code is reviewed and stable.
Question 5: A data analyst needs to visualize geographic sales distribution across US states. Which tool is most specialized for this purpose?
- Microsoft Word
- Google Maps with embedded pins only
- Tableau with geographic maps (Correct answer)
- A standard bar chart in Excel
Correct answer: Tableau with geographic maps
Tableau's built-in geographic mapping capabilities allow analysts to visualize data distributions across regions using filled maps and geocoding.
Question 6: What is the primary purpose of a container orchestration platform like Kubernetes?
- To write application code faster
- To manage and scale containerized applications across clusters (Correct answer)
- To replace databases with file systems
- To compile source code into executables
Correct answer: To manage and scale containerized applications across clusters
Kubernetes automates deployment, scaling, and management of containerized applications across a cluster of machines.
Question 7: A cybersecurity analyst identifies that an attacker is intercepting communications between a client and server without either party knowing. What attack is this?
- Phishing attack
- Man-in-the-Middle (MitM) attack (Correct answer)
- SQL injection
- Denial-of-Service attack
Correct answer: Man-in-the-Middle (MitM) attack
A Man-in-the-Middle attack involves an attacker secretly relaying and possibly altering communications between two parties who believe they are communicating directly.
