Deployment Maintenance and Support

Question 1

Production Environment

Answer 1

Environment in which the hardware and software systems that the user interacts with through the software product.

Question 2

Deployment

Answer 2

The process of making the product available in the production environment

Question 3

Support

Answer 3

After the software product has been deployed, the developer will need to help the customer use it

Question 4

Maintenance

Answer 4

When faults are discovered, the production environment may change and requirements may change, the software product will need to be modified after its deployment

Operating System

Question 17

How are artifacts represented

Answer 17

Rectangles <>

Question 18

How are nodes represented

Answer 18

Boxes <> or description of computational resource.

Answer 20

Dependency arrow with stereotype <>

dotted arrow from artifact to node

Question 21

Deployment Steps

Answer 21

Release - artifacts are assembled into a distributable package
Install - Distributable package is brought to the production env, the artifacts are disassembled and artifacts moved to appropriate nodes
Activate - all executable artifacts are started

Question 22

Installation and activation steps are……

Answer 22

atomic

Question 23

Atomic

Answer 23

Though they appear to involve several actions that occur over time, they must appear to be a single activity

Question 24

Roll back

Answer 24

ability to undo activities and return the production environment to its previous state

Question 25

Ways tot distribute packages?

Answer 25

Stores (apple Store)
Package Manager (dpkg, fink, RPM)
Virtual Machines (Virtual Box, VMWare)
Containers (Docker)

Question 26

Corrective Maintenance

Answer 26

Modifications that correct faults after they give rise to failures

Question 27

Preventive Maintenance

Answer 27

Modifications that correct faults (discovered in the development environment after the product has been deployed) before they give rise to failure in the production env.

Question 28

Adaptive Maintenance

Answer 28

Modification that keep the product usable in a changed or changing env (migration to another platform)

Question 29

Perfective Maintenance

Answer 29

Modification that satisfy additional function requirements (adding new features) or non -functional req. (improving performance)

Question 30

Percentage of effort for development and to a software product and maintenance

Answer 30

20% development

80% software product and maintenance

Question 31

Why is maintenance expensive (3) reasons

Answer 31

• Software written poorly to begin with makes it expensive to maintain and grow features over time
• as software modified over time its structure deteriorates
• Maintenance w/ traditional processes has same problems as original development : new release does not appear for long time and only then do fundamental problems become obvious

Question 32

Professional Support

Answer 32

The person interacting with the user is employed, either directly or indirectly , by the developer or provider of the software product

Question 33

Community Support

Answer 33

The person interacting with the user is another user or an expert who is not employed by the developer or product provider
