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.)
