How does AWS Lambda fundamentally change the way computing resources are used?

  • Free tier with limited usage
  • Hourly billing model
  • Monthly subscription model
  • Pay-per-execution model
AWS Lambda introduces a pay-per-execution model, allowing users to pay only for the compute time consumed by their functions.

For a service that provides access to third-party applications, what authorization mechanism would ensure secure and limited access?

  • API Key Authorization
  • OAuth 2.0
  • Role-Based Access Control (RBAC)
  • SAML (Security Assertion Markup Language)
OAuth 2.0 is commonly used for authorization in scenarios where secure and limited access is required, especially for third-party applications.

What is a primary advantage of using cloud-based web services?

  • Graphic design capabilities
  • Offline functionality
  • Scalability
  • Spreadsheet calculations
Cloud-based web services offer scalability, allowing applications to handle varying workloads efficiently.

An effective way to mitigate XSS is to implement _______ encoding for user inputs.

  • Base64
  • HTML
  • JavaScript
  • URL
Implementing HTML encoding for user inputs is an effective way to mitigate Cross-Site Scripting (XSS) attacks.

What role does an API Gateway play in service discovery in a microservices architecture?

  • It acts as a mediator, directing requests to the appropriate microservices
  • It has no role in service discovery in microservices
  • It hosts the microservices and manages their communication
  • It only provides documentation for microservices
An API Gateway in a microservices architecture plays a role in service discovery by acting as a mediator, directing requests to the relevant microservices based on the request's destination.

In a federated security model, what role does an Identity Provider (IdP) play?

  • It controls access to physical resources
  • It encrypts data during transit
  • It manages user identities and authenticates users
  • It secures the network infrastructure
In a federated security model, an Identity Provider (IdP) manages user identities and authenticates users across multiple systems.

The _______ in UDDI is essential for understanding the functional aspects of a service.

  • Business
  • Metadata
  • Security
  • Technical
The Business facet in UDDI is essential for understanding the functional aspects of a service. It contains information about the service's business-related details, such as its name, description, and contact information. This facet helps service consumers assess the suitability of a service for their needs based on its business context.

In Microservices Architecture, what is the role of an API Gateway?

  • Centralized entry point for handling requests
  • Database management for microservices
  • Load balancing across microservices
  • Microservices monitoring tool
An API Gateway in Microservices Architecture serves as a centralized entry point for handling and routing requests to various microservices.

How can a web service ensure secure transmission of XML data over the internet?

  • Hypertext Transfer Protocol (HTTP)
  • JavaScript Object Notation (JSON)
  • Representational State Transfer (REST)
  • Transport Layer Security (TLS)
Transport Layer Security (TLS) ensures secure transmission by encrypting data during communication over the internet.
