ESB stands for Enterprise Service Bus, which is a middleware architecture that enables communication between disparate applications. It acts as a central hub through which messages are routed, transformed, and managed.
Which protocol is commonly used for lightweight RESTful web services?
HTTP
FTP
SMTP
SSH
HTTP is the primary transport protocol for RESTful web services due to its ubiquity and simplicity. It allows stateless communication using standard methods like GET, POST, PUT, and DELETE.
Which messaging pattern involves a single sender broadcasting messages to multiple subscribers?
Publish-subscribe
Point-to-point
Request-response
Store-and-forward
The publish-subscribe pattern sends a message from one publisher to all interested subscribers. It decouples message producers and consumers and supports many-to-many communication.
Which API management function is responsible for controlling the number of API requests over time?
Rate limiting
Authentication
Data transformation
Orchestration
Rate limiting controls the number of API calls a client can make in a given time period to protect backend services from overload. It helps ensure fair usage and prevents abuse.
What practice ensures that repeated processing of the same message does not produce unintended side effects?
Idempotency
Encryption
Compression
Logging
Idempotency guarantees that performing the same operation multiple times yields the same result without adverse effects. This is crucial in distributed systems to handle retries safely.
In microservices integration, which pattern uses a centralized coordinator to manage service interactions?
Orchestration
Choreography
Broker
Point-to-point
Orchestration employs a central process or service to control and sequence interactions among microservices. It contrasts with choreography, where each service reacts independently based on events.
Which protocol is designed for reliable, message-oriented middleware in enterprise environments?
AMQP
FTP
SMTP
DNS
AMQP (Advanced Message Queuing Protocol) provides a standardized, reliable, and interoperable way to route and queue messages. It supports features like transactions, acknowledgements, and routing capabilities.
What is the primary role of an API Gateway in an integration architecture?
Routing and policy enforcement
Data storage
Service discovery
Encryption only
An API Gateway serves as a single entry point for clients, handling request routing, authentication, rate limiting, and policy enforcement. It decouples clients from backend services and centralizes cross-cutting concerns.
Which middleware component temporarily holds messages when the destination service is unavailable?
Message queue
Cache
API proxy
VPN
A message queue buffers messages until the consumer is ready to process them, enabling asynchronous communication and increased resilience. This decoupling ensures that temporary service outages do not result in message loss.
Which security standard is commonly used for token-based authentication in APIs?
OAuth2.0
SAML
SSL/TLS
LDAP
OAuth 2.0 is widely adopted for granting limited access tokens without exposing user credentials. It supports various flows for web, mobile, and server-to-server authentication.
What is the primary purpose of a dead-letter queue in messaging systems?
Store failed or undeliverable messages for analysis
Encrypt messages at rest
Balance load across consumers
Monitor network traffic
A dead-letter queue holds messages that cannot be delivered or processed due to errors or policy violations. It helps administrators investigate and remediate issues without losing data.
Which messaging pattern is best suited for synchronous client-server interactions?
Request-response
Publish-subscribe
Scatter-gather
Store-and-forward
The request-response pattern involves a client sending a request and waiting for a reply, making it suitable for synchronous operations. It contrasts with asynchronous patterns where the client does not block for a response.
Within a service mesh architecture, which component typically handles security, observability, and traffic routing at the service level?
Sidecar proxy
API gateway
Message broker
Load balancer
A sidecar proxy is deployed alongside each service instance and intercepts inbound and outbound traffic to enforce security policies and collect telemetry. This decentralized approach provides fine-grained control at the service level.
Which type of middleware solution is commonly used for complex data transformation tasks in enterprise integration?
ETL tool
Web server
Firewall
VPN
ETL (Extract, Transform, Load) tools are specialized for extracting data from various sources, transforming it into a desired format, and loading it into target systems. They provide rich transformation features and scheduling capabilities.
What technique helps distribute workload across multiple service instances to improve scalability in integration environments?
Load balancing
Data encryption
Caching
Logging
Load balancing distributes incoming requests evenly across service instances to prevent any single instance from becoming a bottleneck. This improves scalability and fault tolerance in distributed architectures.
Which approach is used to coordinate distributed transactions across multiple heterogeneous systems?
Two-phase commit protocol
Eventual consistency
Circuit breaker
Idempotent receivers
The two-phase commit protocol ensures atomicity by using a prepare and commit phase across all participating systems. It guarantees that either all systems commit the transaction or all roll it back, maintaining data consistency.
Which integration pattern sends requests to multiple services in parallel and gathers the responses into a single aggregated result?
Scatter-gather
Publish-subscribe
Chain of responsibility
Point-to-point
The scatter-gather pattern distributes requests to multiple endpoints concurrently and then aggregates the responses. It is useful for parallel processing and combining results from different services.
When troubleshooting high latency in an integration pipeline, which metric directly measures the number of messages processed per second?
Throughput
Latency
Availability
Utilization
Throughput measures the rate at which a system processes messages over time, typically expressed as messages per second. Monitoring throughput helps identify bottlenecks and capacity limits.
For ensuring payload confidentiality and integrity in API communication beyond transport-level security, which practice is recommended?
Message-level encryption and signing
IP filtering only
DNS-based security
HTTP polling
Message-level encryption and signing secures the actual payload content, ensuring that even if transport channels are compromised, the data remains protected. It also provides integrity checks via digital signatures.
Which streaming platform provides built-in exactly-once processing semantics for integration scenarios?
Apache Kafka with transactions
HTTP long polling
FTP streaming
SMTP batch delivery
Apache Kafka's transaction API enables producers and consumers to commit messages atomically, supporting exactly-once delivery semantics. This is critical for applications that require strong consistency in streaming data pipelines.
