social engineering

8. What is the function of a gratuitous ARP sent by a networked device when it boots up?

to advise connected devices of its MAC address

33. Why would a rootkit be used by a hacker?

to gain access to a device without being detected

19. What are two purposes of launching a reconnaissance attack on a network? (Choose two.)

to scan for accessibility to gather information about the network and devices

3. A user is curious about how someone might know a computer has been infected with malware. What are two common malware behaviors? (Choose two.)

The computer gets increasingly slower to respond. The computer freezes and requires reboots.

35. Which type of security threat would be responsible if a spreadsheet add-on disables the local software firewall?

Trojan horse

by using a filter that inspects DNS traffic

31 Which type of Trojan horse security breach uses the computer of the victim as the source device to launch other attacks?

proxy

17. Which type of attack is carried out by threat actors against a network to determine which IP addresses, protocols, and ports are allowed by ACLs?

reconnaissance

27. A network administrator is checking the system logs and notices unusual connectivity tests to multiple well-known ports on a server. What kind of potential network attack could this indicate?

reconnaissance

49. Why would an attacker want to spoof a MAC address?

so that a switch on the LAN will start forwarding frames to the attacker instead of to the legitimate host

22. Which statement describes an operational characteristic of NetFlow?
