Question: The terms algorithm and cipher describe the formula or process used to perform
encryption.
Ans: True
Question: The Address Resolution Protocol (ARP) includes the ability to authenticate the
systems that use it.
Ans: False
Question: A code is a mechanism that relies on the usage of complete words or phrases,
whereas ciphers utilize single letters to perform encryption
Ans: True
Question: An attack in which a service is overwhelmed by traffic preventing or denying its
legitimate use is called a
Ans: denial of service attack
Question: Which password attack method uses long lists of words that have been
predefined and can be quickly downloaded for use to break a password that is a word or a
name
Ans: Dictionary password attack
Question: Public key infrastructure (PKI) addresses storing, managing, distributing, and
maintaining keys and digital certificates securely

Question: Which step(s) in the information-gathering process does footprinting cover?
Ans: Gathering information and determining the network range
Question: A hierarchical system of servers and services specifically designed to translate IP
addresses into domain names (forward lookups) as well as the reverse (reverse lookups) is
