A. Mitch isn’t the head of security.
B. Security is usually within security products and perimeter devices.
C. The security application is far too expensive.
D. All of the above
Answer: B
Explanation:
Security is usually within security products and perimeter devices and not built into applications. The security products can cover a wide range of applications, can be controlled by a centralized management console, and are further away from application control. However, this approach does not always provide the necessary level of granularity and does not approach compromises that can take place because of problematic coding and programming routines.
QUESTION 72
David is a security administrator at his organization. He is trying to prevent unauthorized access to the corporate wireless network by people loafing around the office. What kind of wireless network threat is he trying to curb?
A. Man-in-the-middle
B. War driving
C. Dictionary attack
D. DNS spoofing
Answer: B
Explanation:
David is trying to curb a war driving attack.
Key Takeaway: War driving refers to driving around town with a laptop looking for WAPs that can be communicated with. The network card on the laptop is set to promiscuous mode and it looks for signals coming from anywhere. After intruders gain access, they may steal Internet access or start damaging your data.
QUESTION 73
You have entered information in the database. It has been changed and is reflected in the database. What has been done?
A. Integrity Check
B. Commit
C. Rollback
D. Savepoint
Answer: B
Explanation:
When information has been changed and the change is reflected, it has been committed. The commit operation completes a transaction and executes all changes just made by the user. These changes can be made to data or schema information. Because these changes are committed, they are then available to all other applications and users. If a user attempts to commit a change and it cannot complete correctly, a rollback is performed.
This ensures that partial changes do not take place and that data are not corrupted.
QUESTION 74
Database models define the relationship between different data elements, dictate how data can be accessed and define acceptable operations, the type of integrity offered, and how the data is organized. What type of database uses attributes and tuples to contain and organize information?
A. Hierarchical Data Model
B. Relational Database Model
C. Network Database Model
D. Object-oriented Database
Answer: B
Explanation:
The relational database model uses attributes and tuples to contain and organize information. The relational database model is the most widely used model. It presents information in the form of tables. A relational database is composed of a two-dimensional table and each table contains unique rows, columns, and cells. Each cell contains only one data value that represents a specific attribute value within a given tuple. These data entities are linked by a relationship that forms the base for organization of data.

QUESTION 76
What is a single link that is pre-established for the purposes of WAN communications between two destinations?
A. Sonnet Links
B. Dedicated Links
C. Telecommunication Links
D. None of the Above
Answer: B
Explanation:
Dedicated links are single links that are pre-established for the purposes of WAN communication between two destinations. It is dedicated, meaning only the destination points can communicate with each other. This link is not shared by any other entities at any time. This was the main way companies communicated in the past because not as many choices were available as there are today. Establishing a dedicated link is a good idea for two locations that will communicate often and require fast transmission and a specific bandwidth, but it is expensive compared to the possible technologies that enable several companies to share the same bandwidth and also share the cost.
