• A. Multi-tier client-server architecture
• B. Master-slave architecture
• C. Distributed component architecture
• D. Peer-to-peer architecture

• A. difficult
• B. expensive
• C. unreliable
• D. difficult and expensive

Explanation: Although frameworks promote reuse, adopting them often requires substantial process changes, training, integration, and maintenance.

• A. Observer pattern
• B. Strategy pattern
• C. Composite pattern
• D. All of the mentioned

Explanation: System infrastructure frameworks provide reusable foundations for areas such as communication mechanisms, user interfaces, and compiler…

• A. Session management
• B. Security
• C. User interaction
• D. Database support

Explanation: This describes database support because the framework expects an external database, such as MySQL, rather than providing its own built-in…

• A. Session management
• B. Security
• C. User interaction
• D. Database support

Explanation: Session management covers creating, maintaining, and terminating user sessions, so session-related classes belong in this category.

• A. Web application frameworks
• B. Middleware integration frameworks
• C. Web application frameworks

• A. COTS-solution systems
• B. COTS-integrated systems
• C. ERP systems
• D. Both COTS-solution and COTS-integrated systems

Explanation: COTS solution systems are generic, commercially available applications configured for a business type, activity, or even an entire…

• A. System infrastructure frameworks
• B. Middleware integration frameworks
• C. Enterprise application frameworks
• D. MVC

Explanation: Middleware integration frameworks provide standards and classes for communication and information exchange between software components.

• A. Process specialization
• B. Platform specialization
• C. Environment specialization

• B. Shared components are woven into an application at different places when the program is compiled
• C. Large-scale systems that encapsulate generic business functionality and rules are configured for an organization
• D. Systems are developed by configuring and integrating existing application systems

Explanation: COTS reuse involves selecting, configuring, and integrating already available application systems rather than building them from scratch.

• A. Application system reuse
• B. Component reuse
• C. Object and function reuse
• D. None of the mentioned

Explanation: A pattern-matching subsystem reused in another application is a reusable component because it provides a distinct piece of functionality…
