Atenção: A questão se refere ao seguinte texto:
Many businesses believe that if they purchase enough equipment, they can create a secure infrastructure. Firewalls, intrusion detection systems and antivirus programs are just some of the tools available to assist in protecting a network and its data. It is important to keep in mind that no product or combination of products will create a secure organization by itself. Security is a process; there is no tool that you can “set and forget”. All security products are only as secure as the people who configure and maintain them. The purchasing and implementation of security products should be only a percentage of the security budget. The employees tasked with maintaining the security devices should be provided with enough time, training, and equipment to properly support the products. Unfortunately, in many organizations security activities are less important than support activities. Highly skilled security professionals are often tasked with help-desk projects such as resetting forgotten passwords, fixing jammed printers, and setting up new employee workstations. For most organizations, the cost of creating a strong security posture is seen as a necessary evil, similar to purchasing insurance. Organizations don’t want to spend the money on it, but the risks of not making the purchase outweigh the costs. Because of this attitude, it is extremely challenging to create a secure organization. The attitude is enforced because requests for security tools are often supported by documents providing the average cost of a security incident instead of showing more concrete benefits of a strong security posture. The problem is exacerbated by the fact that IT professionals speak a different language than management. IT professionals are generally focused on technology. Management is focused on revenue. Concepts such as profitability, asset depreciation, return on investment, and total cost of ownership are the mainstays of management. These are alien concepts to most IT professionals.

What makes determining the causes of project failure so tough are all of the variables involved. Companies, teams, and projects have different sets of requirements and environmental factors that can influence outcome. Small and seemingly harmless circumstances can be like a "snowball" and bring the whole project to a standstill. "Project failure", however, is not synonymous with "project death". There are varying degrees of failure. The most extreme case, of course, is total project cancellation, and perhaps a few broken windows and bruised egos. But a project can also be considered a failure if it deviates too far from original specifications, doesn't meet key user requirements, and is late or over budget. The list of reasons for project failure is a long one, but we can conclude that the main causes are: setting an overly ambitious project scope, absence of project methodology, lack of support from senior management and poor interpersonal skills.

Atenção: A questão se refere ao seguinte texto:
According a recent research, the Americans devote 22,7% of the time they spend on the Internet on social networking sites and blogs. A year ago, this number it was lower than 16%. Driving this trend is the social networking Facebook, which recently celebrated reaching half a billion users worldwide. It claimed an 85% share of social networking use; MySpace came in a distant second with a 5% share; and Twitter with just 1%. For the first time, games beat out e-mail as the No. 2 online time killer, accounting for 10% of time spent. The research found that half of all Americans online spend time playing games like online-gaming Zynga’s explosively popular FarmVille. It was unclear if time spent playing games like FarmVille on Facebook significantly influenced how much time people spend on Facebook. It’s not that people are not e-mailing or using instant messaging. They are engaged in those activities on services such as Facebook. And they are still heavily involved in those activities while online. E-mail was the third most popular activity at 8%, and instant messaging came in fifth at 4%. The other activity on the rise is watching videos and movies on YouTube, Hulu and Netflix, which jumped 12% to account for nearly 4% of all time spent online.
