Question 10

Which of the following is an action that does not help to provide security for an ecommerce site?
A)email filtering products
B)virus protection software
C)URL filtering products
D)private key infrastructure
E)secure socket layering

Accepted Answer

Private key infrastructure (PKI) is not directly related to providing security for an ecommerce site. PKI is a system that uses public and private keys to encrypt and decrypt sensitive information. While PKI can be used in conjunction with other security measures, such as SSL, it is not a specific action that helps to secure an ecommerce site on its own. The other options (email filtering, virus protection, URL filtering, and SSL) are all measures that can contribute to the security and protection of an ecommerce site.

Question 11

What type of computing allows the use of Web services, database services, and application services over the Internet, without having to invest in corporate or personal hardware, software, or software tools?
A)broadcast computing
B)central computing
C)ring computing
D)cloud computing
E)client computing

Accepted Answer

Cloud computing allows for the use of Web services, database services, and application services over the Internet without the need for hardware, software, or software tools on a corporate or personal level.

Question 12

Which of the following is not a part of the Six Sigma methodology?

Question 13

Which of these is not a kind of security?
A)behavioral
B)hierarchical
C)logical
D)physical

Accepted Answer

Behavioral, logical, and physical security are all valid types of security, but "hierarchical" is not a commonly recognized kind of security.

Question 14

While cloud computing is not immune to outages, it can spread the risk of service interruption to multiple servers by:
A)providing many redundant sites.
B)allowing sites to back up their own content as often as they would like.
C)connecting to the internet via satellite.
D)providing both database services and Web services.

Accepted Answer

By providing many redundant sites, cloud computing can ensure that if one server goes down, there are others ready to take over and maintain service continuity. This helps to spread the risk of service interruptions across multiple servers, making the system more resilient and reliable. The other options (B, C, and D) do not necessarily address the issue of spreading the risk of service interruption to multiple servers in the same way that redundant sites do.

Question 15

Which is not an advantage of modular programming?
A)Modules make it easier to see the whole program code.
B)Tracing an error in a module is less complicated.
C)Modules are easier to maintain.

Question 18

Which is an incorrect guideline for modular programming?
A)Keep each module to a manageable size.
B)Pay particular attention to the critical interfaces.
C)Maximize the number of modules the user needs to modify when making changes.
D)Maintain the hierarchical relationships set up in the top-down phases.

Accepted Answer

Maximizing the number of modules the user needs to modify when making changes goes against the principle of modularity, which is to make changes and modifications easier by breaking down a system into smaller, more manageable modules. The correct guideline is to minimize the number of modules that need to be modified in order to make changes to the system. Therefore, option C is incorrect.
