_______ is a common mechanism used in OAuth for client authentication.
- API Key
- Client Credentials
- JWT
- SAML
In OAuth, the Client Credentials grant type is a common mechanism for client authentication. It involves the client (application) presenting its credentials to the authorization server to obtain an access token. This is often used in server-to-server communication or when the client is a trusted entity.
The process of isolating the container's view of the operating system, including file systems and network interfaces, is known as _______ in Docker.
- Containerization
- Isolation
- Segregation
- Virtualization
The process is known as isolation in Docker, where the container has its own isolated view of the operating system.
SAML is mainly used for which type of authentication?
- Biometric Authentication
- Captcha-based Authentication
- Single Sign-On (SSO)
- Two-Factor Authentication (2FA)
SAML (Security Assertion Markup Language) is mainly used for Single Sign-On (SSO) authentication.
In web services, how is a '404 Not Found' error typically resolved?
- Changing the programming language
- Ignoring the error
- Increasing server load capacity
- Providing a valid endpoint URL
A '404 Not Found' error in web services is typically resolved by providing a valid endpoint URL that the service can locate.
Which type of web service is more suitable for asynchronous processing and complex operations?
- JSON-RPC
- REST (Representational State Transfer)
- SOAP (Simple Object Access Protocol)
- XML-RPC
SOAP is more suitable for asynchronous processing and complex operations. It supports features like message queuing and transactions, making it a preferred choice for scenarios where robust communication and coordination are essential.
In token-based authentication, what is the main advantage of using tokens over traditional credentials?
- Compatibility with legacy systems
- Simplicity in implementation
- Stateless nature and scalability
- Strong encryption of credentials
Token-based authentication offers a stateless and scalable solution, as tokens carry the necessary information and reduce the need for server-side storage of session data.
In a scenario involving microservices architecture, why would JWT be preferred over traditional session-based authentication?
- Compatibility with legacy systems
- Simplicity and ease of implementation
- Stateless nature and scalability
- Tight coupling between services
JWT is preferred in microservices architectures due to its stateless nature, making it scalable and efficient. It eliminates the need for centralized session management.
The technique of using _______ tokens can help in preventing CSRF, which is often confused with XSS.
- Anti-CSRF
- HMAC
- JWT
- Session
Using Anti-CSRF tokens is a technique to prevent Cross-Site Request Forgery (CSRF) attacks, often confused with Cross-Site Scripting (XSS).
Which type of encryption is commonly used for securing data in transit?
- AES
- MD5
- RSA
- SSL/TLS
SSL/TLS encryption is commonly used for securing data in transit, providing a secure communication channel over the internet.
In Microservices, _______ helps in managing complex inter-service communication patterns.
- API Gateway
- Docker Container
- Load Balancer
- Service Registry
API Gateway is a crucial component in Microservices architecture, managing and routing requests between services, handling complex communication patterns.
