The correct answer is IPv4 and IPv6. These are both network layer protocols used for routing and forwarding data packets across networks. Ethernet, HTTP, TCP, DHCP, UDP, DNS, and WLAN are not network layer protocols.

The given correct answer is "WEP is a new and safest WLAN encryption technology." This sentence is not true because WEP (Wired Equivalent Privacy) is actually an older and less secure encryption technology for WLAN. It has been largely replaced by more secure options such as WPA (Wi-Fi Protected Access) and WPA2.

DHCP is responsible for allocating IP addresses to devices on a network, sharing the default gateway IP address, and sharing the DNS IP address. However, DHCP does not handle NAT information. NAT is responsible for translating private IP addresses to public IP addresses and vice versa, allowing devices on a private network to access the internet. This is not a feature of DHCP.

The correct answer is "operator." In the context of WAN connectivity, an operator refers to a telecommunications service provider or network operator that is responsible for implementing and managing the wide area network connections. They are the ones who provide the infrastructure and services necessary for connecting different locations over a wide geographic area.

The correct answer is + data packet re-routing. TCP is a reliable, connection-oriented protocol that ensures the delivery of data packets in the correct order. It provides features such as transmission rate control, reliable transfer, connection set-up, and data packet sequence handling. However, TCP does not have a built-in capability for re-routing data packets. This task is typically handled by network routers and not by the TCP protocol itself.

The given statement is not true because both TCP and UDP always carry the port number. The port number is used to identify the specific service or application to which the data traffic is intended.

The first sentence is correct because traffic transmission in a local area network (LAN) is indeed based on MAC addresses. MAC addresses are unique identifiers assigned to network devices, and they are used to determine the destination of network traffic within a LAN. The third sentence is also correct because all devices connected to a LAN must have their own unique MAC address in order to properly communicate on the network.

Single-mode cable has the best quality for the transmission of the optical signal. This is because it has a smaller core size and only allows one mode of light to propagate through it. This reduces the dispersion and attenuation of the signal, resulting in better signal quality and longer transmission distances.

The statement "Independent WLAN base stations are normally used in large wireless LAN implementations" is not true. In large wireless LAN implementations, WLAN base stations are typically controlled by a separate device called a WLAN controller. This allows for centralized management and coordination of multiple base stations.

Unicast is the most common type of transmission because it involves a one-to-one communication model where a single sender transmits data to a single receiver. This type of transmission is widely used in most communication networks, such as the internet, where data needs to be delivered to specific destinations. Broadcast transmission, on the other hand, involves sending data to all connected devices, while multicast transmission involves sending data to a group of specified recipients. However, these types of transmissions are less common compared to unicast.

The statement "Traffic between local area networks require routing" is not true because local area networks (LANs) can communicate with each other without the need for routing. LANs can be connected through a wide area network (WAN) or through a switch or router, but routing is not always necessary for communication between LANs.

The correct answer is WAN and LAN. WAN stands for Wide Area Network, which is a network that covers a large geographical area, such as multiple buildings or cities. LAN stands for Local Area Network, which is a network that covers a small area, such as a home, office, or campus. Both WAN and LAN are considered "generic" network types because they are commonly used and widely recognized. PAN (Personal Area Network) is a network that connects devices within a person's immediate vicinity, MAN (Metropolitan Area Network) is a network that covers a larger area than a LAN but smaller than a WAN, and Home Network refers to a network within a residential setting.

A typical switch can have either 48 ports or 24 ports. These ports are used to connect devices such as computers, printers, and servers to the switch, allowing them to communicate with each other within a local area network (LAN). The number of ports determines the maximum number of devices that can be connected to the switch simultaneously.

The switch forwards traffic in the local network based on MAC addresses, not IP addresses. Switches use MAC addresses to determine the destination of a packet within a local network, while routers use IP addresses to determine the destination of a packet between different networks.

The network mask is not used to calculate one's own IP address from the network address. The network mask is used to determine the network portion and host portion of an IP address. It is used in conjunction with the IP address to determine the network address and the range of valid host addresses within that network.

The IP protocol does not guarantee that packets will reach their destination. It is responsible for routing packets from the source to the destination, but it does not ensure their delivery.

The IP addresses 192.168.169.170, 172.30.40.50, and 10.11.12.13 are private addresses. Private IP addresses are used within a private network and are not routable on the internet. These addresses are reserved for use in local networks and are not unique globally. They are commonly used in home and office networks to connect devices within the network, but they cannot be used to directly access the internet.
