CAD Security & Deployment — Questions and Answers
Question 1: Which security measure helps prevent unauthorized access to an application?
- Disabling error messages
- Authentication (Correct answer)
- Hiding the URL
- Increasing application size
Correct answer: Authentication
Authentication ensures that only authorized users can access an application by requiring login credentials such as a username and password.
Question 2: What is the purpose of data encryption in application security?
- Increase storage space
- Convert data into unreadable format for security (Correct answer)
- Speed up data processing
- Reduce user access
Correct answer: Convert data into unreadable format for security
Encryption protects sensitive information by converting it into unreadable code that can only be decrypted by authorized users.
Question 3: Which security vulnerability occurs when user input is not properly validated?
- Cross-site scripting (XSS)
- SQL injection (Correct answer)
- Denial of service (DoS)
- Brute-force attack
Correct answer: SQL injection
SQL injection occurs when attackers manipulate input fields to execute unauthorized database queries, compromising sensitive data.
Question 4: What is the purpose of role-based access control (RBAC) in an application?
- Increase application speed
- Limit access to features based on user roles (Correct answer)
- Allow public access to all resources
- Store user credentials in plain text
Correct answer: Limit access to features based on user roles
RBAC restricts access to certain features based on a user’s role, ensuring only authorized personnel can perform specific actions.
Question 5: Which deployment strategy involves gradually releasing updates to a small subset of users before a full rollout?
- Blue-green deployment
- Canary deployment (Correct answer)
- Rolling back
- Big bang deployment
Correct answer: Canary deployment
A canary deployment gradually introduces new features to a small group of users, allowing for testing and minimizing risks.
Question 6: Why is continuous deployment beneficial in application development?
- Reduces version control
- Automates the release process for faster updates (Correct answer)
- Eliminates security requirements
- Prevents updates from being deployed
Correct answer: Automates the release process for faster updates
Continuous deployment automates the release process, allowing faster and more reliable delivery of new features and fixes.
