Support for applications. Examples: HTTP, FTP, SMTP ARP Cache Poisoning Attack Correct Answer- An attack in which an attacker changes the MAC addresses of the ARP cache, or "poisons the ARP cache" of victims to the MAC address of the attacker so that conversations get redirected to the attacker Brute-Force Attack Correct Answer- An attack in which the attacker uses every possible combination of characters to guess the password Buffer Overflow Correct Answer- A situation that occurs when a program tries to put more data into a buffer than it was configured to hold CAT 5 Correct Answer- Supports 100Mbps transmission speeds at 100-meter segments. Bandwidth: 100MHz CAT 5e Correct Answer- Supports 1000Mbps transmission speeds at 100-meter segments. Bandwidth: 100MHz CAT 6 Correct Answer- Supports 1000Mbps transmission speeds at 100-meter segments. Bandwidth: 250+MHz CAT 6a Correct Answer- Supports 10Gbps transmission speeds at 100-meter segments. Bandwidth: 500+MHz Data Link Layer Correct Answer- Layer 2 in the OSI model. Provides for the flow of data. Examples: MAC addresses. Denial of Service Attack/DoS Correct Answer- An attack in which service is denied to a computer, network, or serverDictionary Attack Correct Answer- An attack that uses known passwords and many variations (upper- and lowercase and combinations) to try to log in to an account Evil Twin Attack Correct Answer- A situation in which a rogue wireless access point poses as a legitimate one by broadcasting a legitimate SSID and eavesdrops on the wireless network HSM/Hardware Security Module Correct Answer- A hardware security module is a physical computing device that safeguards and manages digital keys f [Show More]
