System integration is best defined as:
The process of installing multiple operating systems
Connecting different computing systems and applications to work as one
Designing only user interfaces
Creating backups of enterprise data
Which of the following is NOT a benefit of system integration?
Improved efficiency
Reduced data accuracy
Cost savings
Better customer experience
A restaurant’s POS sending orders directly to the kitchen display is an example of:
Data silos
Integrated system
Manual entry
Poor decision-making
Which architecture model uses direct connections between all systems?
Star model
Point-to-Point
Hub-and-Spoke
Client-Server
A disadvantage of Point-to-Point integration is:
Easier to manage connections
Becomes unmanageable as systems increase
Centralized monitoring
Redundancy
In a Hub-and-Spoke architecture, the hub is also called:
Database
Central router
Enterprise Service Bus (ESB)
API Gateway
A key drawback of the Hub-and-Spoke model is:
More connections are required
The hub can be a single point of failure
It cannot support new systems
Lack of scalability
Which communication pattern waits for a response before continuing?
Fire-and-Forget
Request-Reply
Batch processing
Hub communication
Example of Request-Reply is:
Logging user activity
Sending emails without waiting
Weather app querying forecast
Background analytics
The Fire-and-Forget pattern is:
Synchronous
Asynchronous
Two-way communication
Always reliable
An example of Fire-and-Forget is:
Requesting weather updates
Logging user visits to analytics
Online payment request
Database queries
Which data format is tag-based and self-describing?
SQL
XML
JSON
HTML
Which data format is lightweight and widely used in web APIs?
XML
JSON
HTML
DTD
Which characteristic is true of XML?
Smaller file size than JSON
Validated with schemas
Derived from JavaScript
Uses key-value pairs only
Which is true of JSON?
Heavier than XML
Based on JavaScript, but language-independent
Requires schemas
Not supported in mobile apps
Which is NOT a problem caused by lack of integration?
Data silos
Improved efficiency
Manual data entry
Poor decision-making
Enterprise Architecture aligns:
IT systems with business goals
User interfaces with colors
Hardware only
Employees with payroll
Scalability planning in Enterprise Architecture ensures:
Systems can grow with the business
Systems stay fixed
Systems cannot communicate
Systems require more redundancy
Without system integration, online stores may show products:
Correctly updated
As “out of stock”
Still available though sold out
With improved accuracy
One major reason businesses adopt integration is:
To increase redundancy
To support real-time decision making
To separate systems
To avoid automation
System integration combines separate (a) into a unified whole.
The biggest risk in a Hub-and-Spoke model is (a) .
The process of connecting systems to communicate is called (a) .
The data format that uses opening and closing tags is (a) .
The lightweight data format commonly used in mobile apps is (a) .
Fire-and-Forget is an example of (a) communication.
Request-Reply is an example of (a) communication.
In Enterprise Architecture, (a) ensures IT supports business objectives.
A benefit of integration that reduces repeated work is (a) .
Information trapped in separate systems is called (a) .
Imagine you are managing an online store. A customer purchases the last item, but your website still shows it as available because the inventory system is not updated. What integration problem occurred?
You are part of an IT team choosing between Point-to-Point and Hub-and-Spoke integration. Your company plans to add many new systems over the next year. Which architecture would you recommend and why?
