Which attack attempts to overwhelm a service or device to make it unavailable to users?
VLAN hopping
DoS
ARP spoofing
DNS poisoning
A coordinated attack using many infected machines at once is called a:
Rogue access attack
Distributed Denial of Service (DDoS)
On-path attack
MAC spoofing
A botnet is best described as:
A cluster of secure servers used for backups
A network of compromised machines controlled remotely
A tool for encrypting network traffic
An approved wireless expansion device
An attacker placing themselves between a victim and the intended destination is known as a:
Deauthentication attack
Botnet attack
On-path (Adversary-in-the-Middle) attack
VLAN hopping attack
What happens during DNS poisoning?
DNS tables are wiped and rebuilt automatically
DNS entries are altered to redirect users to incorrect IP addresses
Users’ passwords are stored in DNS records
DNS servers shut down from overload
Which attack involves a hacker gaining access to restricted VLANs?
Deauthentication
VLAN hopping
IP spoofing
Brute force
What is the goal of ARP spoofing?
Disrupt Wi-Fi signals
Trick devices into sending traffic to the attacker’s MAC address
Break encryption keys
Reset ARP tables to defaults
A rogue DHCP server primarily causes:
Faster IP assignment
Devices to receive incorrect network configuration
Stronger firewall enforcement
Encrypted communication between hosts
Which describes a rogue access point?
A router using MAC filtering
A Wi-Fi device installed without authorization
A government-approved secure hotspot
A personal hotspot created for guests
What is an Evil Twin?
A duplicated VLAN
A Wi-Fi AP mimicking a legitimate SSID to trick users
A type of ransomware
A duplicate IP address on the network
Ransomware is best defined as:
Software that speeds up encryption
Malware that encrypts or steals data and demands payment
A tool for decrypting stolen files
A type of password attack
A dictionary attack:
Uses random characters until a match is found
Uses a predefined list of common passwords
Spoofs the network’s DNS settings
Alters VLAN assignments
MAC spoofing involves:
Breaking router encryption
Cloning the router’s MAC address
Manipulating DNS records
Resetting network adapters
When an attacker falsifies the source of IP packets, it is known as:
IP spoofing
MAC poisoning
DNS tunneling
DHCP flooding
Deauthentication attacks work by:
Encrypting wireless traffic
Sending forged disconnect frames to knock devices off Wi-Fi
Overloading Ethernet switches
Modifying ARP tables
Malware is a general term for:
Encryption algorithms
Any harmful software used for malicious purposes
Backup recovery tools
Authentication protocols
