+# Quiz 15: Software reuse and component-based SWE
+
+## Problem 1
+
+> To make independent, distributed components work together, you need middleware
+  support that handles component communications.
+>
+> 1. True
+> 2. False
+
+**A.** True
+
+## Problem 2
+
+> Which of these are not a method for component composition.
+>
+> 1. Sequential composition
+> 2. Hierarchical composition
+> 3. Parameter composition
+> 4. Additive composition
+
+**C.** Parameter composition
+
+## Problem 3
+
+> Web application security frameworks may help implement user authentication
+  (login) and access control to ensure that users can only access permitted
+  functionality in the system.
+>
+> 1. True
+> 2. False
+
+**A.** True
+
+## Problem 4
+
+> Reuse-based software engineering is an approach to development that tries to
+  minimize the reuse of existing software.
+>
+> 1. True
+> 2. False
+
+**B.** False
+
+## Problem 5
+
+> Potential problems with application system reuse include lack of control over
+  functionality, performance, and system evolution.
+>
+> 1. True
+> 2. False
+
+**A.** True
+
+## Problem 6
+
+> Match the following benefit of Software Reuse with its explanation.
+>
+> - Accelerated development
+> - Effective use of specialists
+> - Increased dependability
+> - Lower development costs
+> - Reduced process risk
+> - Standards compliance
+
+- **E.** Bringing a system to market as early as possible is often more
+  important than overal development costs. Reusing software can speed up system
+  production because both development and validation time may be reduced.
+- **F.** Instead of doing the same work over and over again, application
+  specialists can develop reusable software that encapsulates their knowledge.
+- **C.** Reused software, which has been tried and tested in working systems,
+  should be more dependable than new software. Its design and implementation
+  faults should have been found and fixed.
+- **B.** Development costs are proportional to the size of the software being
+  developed. Reusing software means that fewer lines of code have to be written.
+- **A.** The cost of existing software is already known, while the costs of
+  development are always a matter of judgment. This is an important factor for
+  project management because it reduces the margin of error in project cost
+  estimation. This is especially true when large software components such as
+  subsystems are reused.
+- **D.** Some standards, such as user interface standards, can be implemented as
+  a set of reusable components. For example, if menus in a user interface are
+  implemented using reusable components, all applications present the same menu
+  formats to users. The use of standard user interfaces improves dependability
+  because users make fewer mistakes when presented with a familiar interface.
+
+## Problem 7
+
+> Component-based software engineering is not a reuse-based approach. It is mean
+  to develop systems that are implemented once and solely used for that
+  application.
+>
+> 1. True
+> 2. False
+
+**B.** False
+
+## Problem 8
+
+> One of the only ways to meet the demands of secure, dependable, and quickly
+  deployed software is to use component based SWE.
+>
+> 1. True
+> 2. False
+
+**A.** True
+
+## Problem 9
+
+> At the highest level, there are two types of CBSE processes:
+>
+> <ol style="list-style-type: decimal;">
+>  <li>Development for reuse</li>
+>  <li>Development with resue</li>
+> </ol>
+>
+> 1. True
+> 2. False
+
+**A.** True
+
+## Problem 10
+
+> The advantages of software reuse are lower costs, and faster software
+  development. A disadvantage is higher risks.
+>
+> 1. True
+> 2. False
+
+**A.** True
