For monitoring Microservices, _______ is an essential practice.
- Code Obfuscation
- Distributed Tracing
- Static Analysis
- Uptime Monitoring
Distributed Tracing is essential for monitoring Microservices, allowing tracking and analysis of requests as they traverse through various services.
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.
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.
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.
_______ 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.
In the RESTful API design, the version number is often included in the _______.
- Headers
- Query Parameters
- Request Body
- URL
In RESTful API design, version numbers are often included in the URL to specify the desired API version.
In ensuring interoperability, _______ plays a crucial role in defining security protocols for web services.
- REST
- SOAP
- WSDL
- XML Security
In ensuring interoperability, SOAP (Simple Object Access Protocol) plays a crucial role in defining security protocols for web services. SOAP provides a standardized way to communicate and exchange information between different systems, contributing to secure and reliable interoperability in distributed environments.
REST services typically exchange data in which format?
- HTML
- JSON
- Plain Text
- XML
REST services typically exchange data in JSON (JavaScript Object Notation) format. JSON is a lightweight and readable data interchange format that is easy for both humans to understand and machines to parse, making it well-suited for data exchange in RESTful architectures.
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.
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.
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).
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.
