Which layer of the TCP/IP model includes the Internet Protocol (IP)?
The Network or Internet layer of the TCP/IP model is responsible for addressing, routing, and delivering packets across networks. The Internet Protocol (IP) operates at this layer, ensuring that data is correctly routed from the source to the destination.
Physical or network access layer deals with hardware transmission (e.g., Ethernet, Wi-Fi).
Application layer includes end-user services (e.g., HTTP, FTP).
Transport layer manages data flow using protocols like TCP and UDP but does not handle IP addressing.
Users of a network have been experiencing issues. In the course of troubleshooting, an administrator wants to test DNS resolution against a host.
Which command in Linux should be used for this purpose?
The dig command in Linux is used for DNS troubleshooting. It queries DNS records and provides detailed information about domain name resolutions.
traceroute tracks the path packets take to a destination but does not diagnose DNS.
netstat lists active connections, not DNS records.
ifconfig is used for managing network interfaces.
What is the layer of the OSI model that creates, maintains, and disconnects process communications over the network?
The Session layer (Layer 5 of the OSI model) is responsible for establishing, maintaining, and terminating communication sessions between network applications. It ensures that data exchanges remain synchronized and structured.
Data link layer handles error detection and frame transmission.
Physical layer deals with hardware-level transmission.
Transport layer ensures reliable data delivery but does not manage sessions.
Which layer of the TCP/IP model includes the Internet Protocol (IP)?
The Network or Internet layer of the TCP/IP model is responsible for addressing, routing, and delivering packets across networks. The Internet Protocol (IP) operates at this layer, ensuring that data is correctly routed from the source to the destination.
Physical or network access layer deals with hardware transmission (e.g., Ethernet, Wi-Fi).

What is the type of cyberattack described in this scenario?
Social engineering involves manipulating people into divulging confidential information, often by impersonation, deception, or psychological tactics. Using a forged ID card to gain trust and extract sensitive information is a classic example of social engineering.
Brute-force attack attempts to guess passwords through automated methods.
Man-in-the-middle attack intercepts communication but does not rely on deception.
Pharming tricks users into visiting fraudulent websites but does not involve impersonation.
