Which transport layer protocol is used for DNS queries and why? a) TCP, because it provides reliable data transmission b) UDP, because it is faster and DNS queries are typically small c) HTTP, because it supports web applications d) FTP, because it handles file transfers 11 / 30 11. What is a modem in computer networking? a) A device used to connect different networks and forward data packets between them b) A device used to connect multiple devices within a LAN and manage network traffic c) A device used to amplify network signals d) A device used to modulate and demodulate digital signals for transmission over communication lines 12 / 30 12. What is the role of the attacker in a Man-in-the-Middle (MitM) attack? a) The attacker acts as a passive observer, simply intercepting communication between two parties. b) The attacker acts as an active participant, engaging in communication with both parties while intercepting and potentially altering the messages. c) The attacker acts as a defender, protecting the communication between two parties from external threats. d) The attacker acts as a mediator, facilitating communication between two parties without interfering with the messages. 13 / 30 13. What is the `ping` command used for? a) To trace the route to a destination host b) To display network interface configuration information c) To check the connectivity between the local host and a remote host d) To display the routing table of the local host 14 / 30 14. What is the primary disadvantage of WPA2-Enterprise authentication compared to WPA2-PSK? a) Lower security due to shared security key b) Higher resource consumption and complexity of setup c) Limited compatibility with older devices and networks d) Slower authentication and network performance 15 / 30 15. What is Transport Layer Security (TLS)? a) Transport Layer Security (TLS) is a protocol that encrypts data transmitted over a network to ensure its security and integrity. b) Transport Layer Security (TLS) is a firewall that monitors and filters incoming and outgoing network traffic. c) Transport Layer Security (TLS) is a network access control mechanism that grants or denies access to network resources based on defined rules. d) Transport Layer Security (TLS) is a network routing protocol used to determine the best path for data transmission. 16 / 30 16.
