DNS
HTTP or HTTPS

Explanation: A cybercriminal could set up a rogue DHCP server that provides i or more of the following:

Wrong default gateway that is used to create a man-in-the-middle attack and allow the attacker to intercept information
Incorrect DNS server that results in the user being sent to a malicious website
Invalid default gateway IP address that results in a denial of service assail on the DHCP client

48. In which TCP attack is the cybercriminal attempting to overwhelm a target host with one-half-open TCP connections?

reset attack
session hijacking set on
SYN flood set on
port browse attack

Explanation: In a TCP SYN overflowing set on, the attacker sends to the target host a continuous alluvion of TCP SYN session requests with a spoofed source IP address. The target host responds with a TCP-SYN-ACK to each of the SYN session requests and waits for a TCP ACK that volition never arrive. Eventually the target is overwhelmed with half-open TCP connections.

49. Which statement describes a VPN?

VPNs employ logical connections to create public networks through the Internet.
