Incomplete question. The full question read;
Why is Jim having these problems?
Options:
A. Security scanners are not designed to do testing through a firewall.
B. Security scanners cannot perform vulnerability linkage.
C. Security scanners are only as smart as their database and cannot find unpublished vulnerabilities.
D. All of the above.
Answer:
<u>D. All of the above.</u>
Explanation:
<em>Remember, </em><u>security scanners</u> are only designed to <em>gather</em> information about a network, but not with the ability to perform firewall testing. Also, these security scanners are pre-programmed with existing vulnerabilities in their database, and so it would impossible to discover vulnerabilities on the Retail store's network.
Hence, since Bob is using the wrong tools, he is unsuccessful in performing a penetration test.

Answer:
Physical / Data link layer
Explanation:
If two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the data would be transmitted if the network is clear but if the network is not clear, the transmission would wait until the network is clear.
The Open Systems Interconnection model (OSI model) has seven layers each with its own function.
The physical layer is the first layer responsible for data transmission over a physical link. The data packets are converted to signals over a transmission media like ethernet cable.
The data link layer is the second layer in the OSI layer responsible for transmission of data packets between nodes in a network. It also provides a way of detecting errors and correcting this errors produced as a result of data transmission.
Answer:
A compiler takes a lot of time to analyze the source code. However, the overall time taken to execute the process is much faster. An interpreter does not generate an intermediary code. Hence, an interpreter is highly efficient in terms of its memory.
