1. What is the primary purpose of system integration in enterprise
environments?
A. To replace all legacy systems immediately
B. To enable different systems to work together as a unified whole
C. To eliminate the need for databases
D. To reduce hardware usage only
System integration focuses on ensuring that diverse software and
hardware systems communicate and operate cohesively, improving
efficiency and data consistency across an organization.
2. Which protocol is most commonly used for lightweight machine-to-
machine communication in IoT integration?
A. FTP
, B. MQTT
C. SMTP
D. Telnet
MQTT is designed for low-bandwidth, high-latency networks and is
widely used in IoT systems for efficient message exchange.
3. What does API stand for in systems integration?
A. Automated Process Interface
B. Application Programming Interface
C. Advanced Protocol Integration
D. Applied Program Interaction
An API defines rules that allow different software applications to
communicate and exchange data effectively.
4. Which architecture style is most commonly associated with loosely
coupled services?
A. Monolithic architecture
B. Microservices architecture
C. Batch processing architecture
D. Waterfall architecture
Microservices break applications into independent services that
communicate over APIs, improving scalability and maintainability.
5. What is the primary function of middleware in system integration?
A. To replace operating systems
B. To facilitate communication between applications and systems
, C. To design user interfaces
D. To store hardware drivers
Middleware acts as a bridge enabling communication and data
management between different applications or services.
6. Which protocol is commonly used for secure web-based API
communication?
A. HTTP
B. HTTPS
C. FTP
D. SNMP
HTTPS provides encrypted communication over HTTP using TLS/SSL
for secure data exchange.
7. What is the role of an Enterprise Service Bus (ESB)?
A. To replace all databases
B. To integrate and route messages between services in an
enterprise
C. To design user interfaces
D. To compile source code
An ESB enables communication between different applications by
routing and transforming messages in a service-oriented
architecture.
8. Which of the following best describes ETL in data integration?
A. Execute, Test, Launch
, B. Extract, Transform, Load
C. Encrypt, Transfer, Log
D. Evaluate, Transfer, Link
ETL processes extract data from sources, transform it into usable
formats, and load it into target systems like data warehouses.
9. Which technology is commonly used for containerization?
A. VirtualBox
B. Docker
C. Jenkins
D. Kubernetes Dashboard
Docker allows applications to be packaged with dependencies into
containers for consistent deployment.
10. What is the main advantage of using containers in system
integration?
A. Increased hardware dependency
B. Portability across environments
C. Reduced network speed
D. Elimination of APIs
Containers ensure applications run consistently across different
computing environments.
11. Which system is commonly used for orchestration of containers?
A. Apache Hadoop
B. Kubernetes
