What is OpenID Connect and how is it related to OAuth 2.0?

  • A data encryption method
  • A database management system
  • A version of HTML
  • An authentication protocol
OpenID Connect is an authentication protocol that builds on top of OAuth 2.0. It allows applications to verify the identity of users based on the authentication performed by an authorization server. While OAuth 2.0 is primarily for authorization, OpenID Connect adds an identity layer, making it easier to obtain user profile information and ensure secure user authentication.

What is the structure of a JSON Web Token?

  • Encrypted binary format
  • Header, payload, and signature
  • Unstructured data
  • XML-based format
The structure of a JSON Web Token (JWT) consists of three parts: the header, payload, and signature. The header contains information about the type and the signing algorithm used. The payload contains claims or information about the user. The signature is a cryptographic signature of the header and payload, ensuring data integrity and authentication.

How does OpenID Connect ensure that tokens are not misused or intercepted?

  • By encrypting tokens using a secure algorithm
  • By regularly changing the tokens' expiration times
  • By requiring users to memorize long token strings
  • By using HTTPS for secure transmission of tokens
OpenID Connect ensures that tokens are not misused or intercepted by using HTTPS for secure transmission. This means that tokens are sent over encrypted connections, reducing the risk of eavesdropping and interception. The use of HTTPS is a fundamental security measure for protecting the confidentiality and integrity of tokens in transit.

Why is it important to monitor APIs after deployment?

  • To add more features
  • To ensure high availability
  • To impress stakeholders
  • To reduce development costs
Monitoring APIs after deployment is essential to ensure high availability and reliability. It allows for real-time tracking of API performance, identifying and addressing issues, and ensuring that the API meets the needs of users. While adding more features and impressing stakeholders are important, the primary goal of monitoring is to maintain service availability and quality.

What is an API key?

  • A programming language used for API development
  • A standardized document describing an API's usage
  • A unique code passed with API requests
  • A unique identifier for the API provider
An API key is a unique code that is typically passed with API requests. It serves as an access token, allowing the API provider to identify and authenticate the user or application accessing the API. API keys are used to control access, track usage, and ensure security in API interactions.

Effective API troubleshooting often involves analyzing _____ to identify patterns or anomalies.

  • Code
  • Design
  • Error messages
  • Logs
Effective API troubleshooting often involves analyzing logs to identify patterns or anomalies. Logs contain a record of events and activities within an application or system, including error messages and other relevant information. By examining logs, developers and administrators can gain insights into the API's behavior and diagnose issues, which is essential for effective troubleshooting.

What types of issues might you encounter when debugging an API?

  • All of the above
  • Authentication issues
  • Data serialization errors
  • Network latency problems
Debugging an API can involve various issues, including network latency problems, authentication issues, and data serialization errors. These issues can impact the proper functioning of the API and need to be addressed during the debugging process.

How does load testing for APIs differ from performance testing?

  • Load testing and performance testing are the same thing.
  • Load testing assesses the speed and scalability of an API.
  • Load testing checks for API compatibility with various browsers.
  • Performance testing evaluates the API's security features.
Load testing for APIs focuses on assessing how well the API performs under varying levels of load, such as concurrent users or data volume. Performance testing, on the other hand, encompasses a broader evaluation of the API's overall capabilities, including speed, scalability, security, and more.

How can logging be used effectively in API troubleshooting?

  • Logging can be used to track requests and responses
  • Logging is essential for API security
  • Logging is not useful for troubleshooting APIs
  • Logging is only helpful for tracking errors
Logging can be effectively used in API troubleshooting to track requests and responses. It helps in identifying issues, analyzing traffic, and monitoring performance, which is crucial for debugging and maintaining API functionality.

Automating ________ tests ensures that the API functions correctly in a real-world scenario, from start to finish.

  • Functional
  • Integration
  • Regression
  • Unit
Automating functional tests ensures that the API functions correctly in a real-world scenario, from start to finish. Functional tests verify that the API performs its intended tasks and provides the expected results, making them critical for ensuring the API's overall reliability and functionality.
