With a packet switched network, packets are difficult to monitor because they can be transmitted using different paths.
A packet-switched network is a digital communications network that groups all transmitted data, irrespective of content, type, or structure into suitably sized blocks, called packets.
The network over which packets are transmitted is a shared network which routes each packet independently from all others and allocates transmission resources as needed.
The principal goals of packet switching are to optimize utilization of available link capacity, minimize response times and increase the robustness of communication. When traversing network adapters, switches and other network nodes, packets are buffered and queued, resulting in variable delay and throughput, depending on the traffic load in the network.
Most modern Wide Area Network (WAN) protocols, including TCP/IP, X.25, and Frame Relay, are based on packet-switching technologies. In contrast, normal telephone service is based on a circuit-switching technology, in which a dedicated line is allocated for transmission between two parties. Circuit-switching is ideal when data must be transmitted quickly and must arrive in the same order in which it's sent. This is the case with most real-time data, such as live audio and video. Packet switching is more efficient and robust for data that can withstand some delays in transmission, such as e-mail messages and Web pages.

Section: Risk, Response and Recovery
Explanation/Reference:
Why is this the correct answer? Simply because it is WRONG, you would have contact information for your emergency personnel within the plan but NOT for ALL of your personnel. Be careful of words such as ALL.
According to NIST's Special publication 800-34, contingency plan appendices provide key details not contained in the main body of the plan. The appendices should reflect the specific technical, operational, and management contingency requirements of the given system. Contact information for recovery team personnel (not all personnel) and for vendor should be included, as well as detailed system requirements to allow for supporting of system operations. The Business Impact Analysis (BIA) should also be included as an appendix for reference should the plan be activated.

The biggest factor that makes Computer Crimes possible is Victim
Carelessness. Awareness and education can reduce the chance of someone becomming a
victim.
The types and frequency of Computer Crimes are increasing at a rapid rate. Computer
Crime was once mainly the result of insiders or disgruntled employees. Now just about
everybody has access to the internet, professional criminals are taking advantage of this.
Specialized skills are no longer needed and a search on the internet can provide a
fraudster with a plethora of tools that can be used to perpetuate fraud.
All too often carelessness leads to someone being a victim. People often use simple
passwords or write them down in plain sight where they can be found by fraudsters. People
throwing away papers loaded with account numbers, social security numbers, or other
types of non-public personal information. There are phishing e-mail attempts where the
fraudster tries to redirect a potential victim to a bogus site that resembles a legitimate site
in an attempt to get the users' login ID and password, or other credentials. There is also
social engineering. Awareness and training can help reduce the chance of someone
becoming a victim.
The following answers are incorrect:
The fraudster obtaining advanced training and special knowledge. Is incorrect because
training and special knowledge is not required. There are many tools widely available to
fraudsters.
Collusion with others in information processing. Is incorrect because as more and more
people use computers in their daily lives, it is no longer necessary to have someone on the
inside be a party to fraud attempts.
System design flaws. Is incorrect because while System design flaws are sometimes a
factor in Computer Crimes more often then not it is victim carelessness that leads to
Computer Crimes.

Section: Security Operation Adimnistration
Explanation/Reference:
Complex Instruction Set Computer (CISC) uses instructions that perform many operations per instruction. It was based on the fact that in earlier technologies, the instruction fetch was the longest part of the cycle.
Therefore, by packing more operations into an instruction, the number of fetches could be reduced. Pipelining involves overlapping the steps of different instructions to increase the performance in a computer. Reduced Instruction Set Computers (RISC) involve simpler instructions that require fewer clock cycles to execute. Scalar processors are processors that execute one instruction at a time.
