What is a primary challenge when implementing Microservices Architecture?
- Monolithic Deployment
- Service Coordination
- Single Database Structure
- Tight Coupling
One of the primary challenges in Microservices Architecture is managing service coordination to ensure effective communication and collaboration among services.
How does a RESTful service maintain its statelessness?
- Stateless communication
- Through client sessions
- Using cookies for state
- Via server-side sessions
RESTful services maintain statelessness by not storing client state on the server between requests. Each request from a client contains all the information needed to understand and process the request.
_______ is essential for ensuring web services comply with legal and ethical standards.
- Authentication
- Authorization
- Compliance
- Encryption
Compliance is essential for ensuring that web services adhere to legal and ethical standards.
The ________ protocol in HTTPS ensures confidentiality, integrity, and authentication of data.
- HTTP
- SSL
- TCP
- TLS
In HTTPS, the TLS (Transport Layer Security) protocol ensures confidentiality, integrity, and authentication of data. TLS is the successor to SSL (Secure Sockets Layer) and provides a secure communication channel over the Internet, safeguarding sensitive information during transmission.
SOA governance involves _______ to ensure that services meet business objectives.
- Policies and Procedures
- Service Level Agreements (SLAs)
- Simple Object Access Protocol (SOAP)
- Web Services Security
SOA governance involves the implementation of policies and procedures to ensure that services adhere to standards, security measures, and service level agreements (SLAs). These governance practices are essential for maintaining consistency and meeting business objectives in SOA.
HTTP requests are vulnerable to ________, which is largely mitigated in HTTPS.
- Cross-Site Scripting (XSS)
- DDoS (Distributed Denial of Service) Attack
- Man-in-the-Middle (MITM) Attack
- SQL Injection
HTTP requests are vulnerable to Man-in-the-Middle (MITM) attacks, where an attacker intercepts and potentially alters the communication between the client and server. HTTPS helps mitigate this vulnerability by encrypting the data, making it harder for attackers to tamper with or eavesdrop on the communication.
UDDI registries are used to store information about:
- Businesses and their web services
- Server hardware specifications
- User authentication credentials
- Web page layouts
UDDI registries are used to store information about businesses and their web services, facilitating the discovery and integration of these services by other businesses.
Azure's Virtual Machines are primarily used for what?
- Deploying serverless functions
- Managing DNS and domain registration
- Running applications in a scalable cloud environment
- Storing large amounts of unstructured data
Azure Virtual Machines are designed for running applications in a scalable cloud environment by providing on-demand computing resources.
In API management, how does an API Gateway optimize API traffic between services and external clients?
- Caching frequently requested responses
- Ignoring client-side optimizations
- Increasing API response time
- Introducing additional latency
An API Gateway optimizes API traffic by caching frequently requested responses, reducing the need to make repeated calls to backend services.
What distinguishes symmetric encryption from asymmetric encryption?
- Different keys for encryption and decryption
- Only used for secure web communication
- Same key for both encryption and decryption
- Uses a key pair for encryption
Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses different keys for these operations.
