Computer Science Homework Help

Part one:

Your task:

A list of networking devices has been to you for your approval or disapproval. Based of the given business requirements, for each of the networking devices, you shall either approve or disapprove it to be used in building a network to support the business operations/requirements.

Hints:

• • You disapproved a device for an incorrect reason.
  • You approved a device that will put Ava’s business at risks – You did not fully understand the device that you approved or you did not fully understand Ava’s business requirements.
  • You disapproved a device without providing your reason(s).
  • You included at least one incorrect statement in your solution; for example, 1 day has 36 hours or the Internet is the same as the World Wide Web.

• All networking devices are subject to security vulnerability and risks.
• If a device can satisfy the requirements, it cannot be disapproved, regardless its capability, performance, intelligence, or cost.
• You are NOT asked to provide definitions nor capabilities of these devices, because you are required to fully understand these devices; otherwise, your decision cannot be right.
• You are NOT asked to make a selection or recommendation, because making a selection or recommendation concerns the cost. There is no mention of “cost” in the requirements.
• There is no mention of “performance” nor “traffic” in the requirements. If your solution talks about performance or efficiency, your solution is incorrect.
• No partial credits can be awarded. Why? If you made incorrect decisions, the new network will FAIL to satisfy the business and will put the business at risks. You may be asked to pay back the business loss. You will be fired. Yet, you would still ask for partial credits??!!
• A reason is a fact and is not an opinion. For example, “….not flexible…”, “…poor performance…”, “…more expensive….” are opinions.
• There is only one correct solution. — This is NOT same as “one device”.
• Your solution is incorrect, if:

Part 2:

Your task:

In a job interview, a real-word scenario related to PCI DSS compliance and regulations is presented to you. You are asked to given an explanation to demonstrate your knowledge in PCI DSS relevant to computer networks used in the given business environment.

Hints:

• It is job interview question — Your answer should be as short as one sentence to four sentences.
• PCI DSS Requirement #9 is NOT about “Physical Security”.
  • “Physical Access” is NOT the same as “Physical Security”.
  • If you talked about physical security, your solution is incorrect.
  • If you talked about security cameras, sign-in logs, access records…., your solution is incorrect.
• If you talked about “no security measures”, your solution is incorrect. What do you mean by “no security measures” and how can you tell from the diagram that there are no security measures?
• You must fully understand PCI DSS Requirement #9 before working on this assignment.
• If you fully understand PCI DSS Requirement #9, you will know the solution.
• HW#4 does not ask you to provide the definition and does not ask you to explain what PCI DSS Requirement #9 is.
