1) Explain the IT processes, techniques, devices, and components of requesting and responding to a Web page inquiry; assume the client is an android smartphone and the Web page is found.

            Provide sufficient detail to demonstrates understanding.

            Topics that should be addressed include but are not limited to:

·       Client/Server environment with dedicated Web server, separate database server, & use of Proxies

·       HTTP

·       DNS  (why needed?   Difference url& IP Address)

·       TCP/IP Layers (name & function/purpose)

·       TCP/IP Layer movement need only be explained in detail once – must have some kind of statement addressing “reverse” process but  may be void of same level of detail already expressed in response

·       Routers  (functions & decisions)

·       Security  (HTTPS, SSL)

·       Ports (80)

·       etc.

Ch 8 p225-227

2) Explain the IT processes, techniques, devices, and components of requesting retrieval of a customer’s record from an enterprise database that DIFFER from the Web request above

            Provide sufficient detail to demonstrates understanding.  Limit response to items that are different

            Hints:   Internal vs External possibility?  Assume Intranet login plus app-specific login required to access Customer app

            Port Number

            Differentiated Service traffic  (Ch 11)

Message Passing Ch 9 p257

3) Explain SOA

            Provide sufficient detail that demonstrates understanding –

            including what it is, what it does, how it operates, what is and is not included,

            why a business would apply it e.g. benefits,

            how it is different from and/or similar to Object Oriented Programming & Middleware

4) Compare and contrast the security techniques:

     HTTPS, IPSec, SSH, SSL, and VPN 

Describe function, what is protected, what is NOT protected, where (TCP/IP Model layer and/or communication process) applied for each term and identify any relationships (e.g. HTTP & SSL, VPN & IPSec both apply encryption to ensure security, etc.)
