Potential Drawbacks of Cloud Computing

Security and Availability

Security and availability are still the main concerns that most people have about relying on cloud-based services.
You've probably heard of the many high-profile news stories of security breaches in cloud-based services. Although you should certainly think about the implications of a breach in your organizational data, you should also consider that in both cloud-based and on-premises software, most security breaches are attributable to human error. That is one reason why we published our 12 Tips to Being Safer Online.
When thinking about cloud security and availability, you should also have a realistic sense of your current technology situation. Fears about the cloud are sometimes based on a utopian vision of an organization's current situation. Odds are that your security isn't perfect, you don't have 100 percent systems uptime, and you may not have staff resources dedicated to IT management. In the cloud, security and management are in the hands of trained, dedicated experts.

Cloud Vendors Going Out of Business

Cloud computing is still a quickly changing field, and there's always the danger that a new company might go out of business or radically change its service. A sudden change in service might not be too detrimental if you were only using the application for a one-time project, but it could be disastrous if you were using it for your entire donor database.
When evaluating cloud providers, find out what options you have for backing up and extracting your data. The best services allow you to download your data in a standard, nonproprietary format.

The Need for Reliable Internet Service

Finally, you will become more dependent on a good Internet connection if you rely on the cloud. As more mission-critical work is done on the Internet, organizations will need much more bandwidth and few, if any, failures in Internet connectivity. If consistent Internet access, connection speed, or bandwidth are problems for your organization, cloud solutions may not be right for you at this time.

Which of the following is not a typical business objective of IT outsourcing and cloud computing?

Which of the following is not a typical business objective of IT outsourcing and cloud computing?

• Eliminating noncore activities
• Improving cost structure
• Lack of skilled staff
• Solving security problems 

EXPLANATION

Solving Security problems are not a typical reason for outsourcing or cloud adoption.
A, B, and C are incorrect. Eliminating noncore activities, a lack of internal skilled staff, and improving cost structure (CAPEX to OPEX) are all common reasons that companies choose to outsource or adopt cloud solutions. Remember that cloud computing is a form of outsourcing.

Which of the following is NOT specifically considered a cloud computing risk?

Which of the following is NOT specifically considered a cloud computing risk?

• Loss of network connectivity
• Host-based firewalls that you manage
• Network latency
• Data stored in the cloud 

EXPLANATION

I just answered that question and apparently I was wrong. 

Of the 4 answers provided, I selected "latency" for a variety of reasons, mostly because I felt it was the least wrong.  The item which was marked as "correct" is, in fact, a very big risk.
She would have been better off asking "Which of these is software?"
 * Loss of network connectivity    * Host-based firewalls that you manage
 * Network latency          * Data stored in the cloud
Given that the original comment on this question was posted on August 9th and today is August 30th, you've had 3 weeks to fix this question, Spiceworks, and yet it remains in circulation.  Are you all on a go-slow or do you just not understand how poor this question is?

How many wire pairs are required for Gigabit Ethernet?

How many wire pairs are required for Gigabit Ethernet?

• 3
• 4
• 6
• 2 

EXPLANATION

How many pairs of wire does gigabit ethernet use on utp cable?

4 pairs of wires.


Ethernet Cat 5 cables have eight wires (four pairs), but under 10BaseT and 100BaseT standards (10 Mbps and 100 Mbps, respectively) only four (two pairs) of these wires are actually used. One pair is used for transmitting data and the other pair is used for receiving data.

Pin	Color	Function
1	White with Green	+TD
2	Green	-TD
3	White with Orange	+RD
4	Blue	Not Used
5	White with Blue	Not Used
6	Orange	-RD
7	White with Brown	Not Used
8	Brown	Not Used

Ethernet standard uses a technique against electromagnetic noise called cancellation. As electrical current is applied to a wire, it generates an electromagnetic field around the wire. If this field is strong enough, it can create electrical interference on the wires right next to it, corrupting the data that were being transmitted there. This problem is called crosstalk.
