Question 344
Which of the following is less likely to accompany a contingency plan, either within the plan itself or in the form of an appendix?
Correct Answer: A
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.

Question 345
Which layer of the DoD TCP/IP Model ensures error-free delivery and packet sequencing?
Correct Answer: C
This layer of the DoD Model is also sometimes called Transport in some books but the proper name is Host-to-Host as per the RFC document. The host-to-host layer provides for reliable end-to-end communications, ensures the data's error-free delivery, handles the data's packet sequencing, and maintains the data's integrity. It is comparable to the transport layer of the OSI model.

Question 346
Which of the following statements pertaining to link encryption is false?
Correct Answer: C
Section: Network and Telecommunications Explanation/Reference: When using link encryption, packets have to be decrypted at each hop and encrypted again. Information staying encrypted from one end of its journey to the other is a characteristic of end-to-end encryption, not link encryption. Link Encryption vs. End-to-End Encryption Link encryption encrypts the entire packet, including headers and trailers, and has to be decrypted at each hop. End-to-end encryption does not encrypt the IP Protocol headers, and therefore does not need to be decrypted at each hop.
