1Both Ethernet (wired LAN) and WiFi (wireless LAN) use CRC for error detection.
- ATrue
- BFalse
2Compared to wired LANs (Ethernet), devices in a wireless LAN cannot reliably detect collisions.
- ATrue
- BFalse
3A WiFi signal transmitted on a 5GHz band is affected by a path loss that is less than the path loss affecting a WiFi signal transmitted on a 2.5GHz band for the same transmission distance.
- ATrue
- BFalse
4Ethernet switches identify the destination using the IP address in packet.
- ATrue
- BFalse
5Hubs broadcast incoming frames, and hence form a network with a logical bus topology.
- ATrue
- BFalse
6An Ethernet switch uses the destination address in a frame to build a switch table.
- ATrue
- BFalse
7In virtual LANs, devices are connected based on their logical functions and not necessarily their physical location.
- ATrue
- BFalse
8When an end device transmits a packet over a physical medium, it contains either IP addresses or MAC addresses.
- ATrue
- BFalse
9In virtual circuit packet switching, packets from the same source to the same destination can go through different routes.
- ATrue
- BFalse
10The time to live field of an IP packet indicates the remaining life of the packet in network hops.
- ATrue
- BFalse
11The network layer is responsible for transferring packets of data from the source device to the destination via one of more networks.
- ATrue
- BFalse
12The main advantage of address classes is that IP addresses are not wasted.
- ATrue
- BFalse
13Using CIDR, the leftmost bits of an IP address identify the network in which the host is located.
- ATrue
- BFalse
14With CIDR, each organization can choose any length for a network ID in the IP address based on the number of hosts they need to support.
- ATrue
- BFalse
15An organization with a /20 CIDR address block can have at most 2^20 hosts.
- ATrue
- BFalse
16Subnetting is a way of breaking down large blocks of IP addresses into smaller address blocks.
- ATrue
- BFalse
17A host uses the subnet mask to identify whether the destination is on the same subnet.
- ATrue
- BFalse
18Each subnet within an organization has a unique address.
- ATrue
- BFalse
19When the subnet mask 255.255.255.0 is applied to the IP address 192.168.151.45, the masked address is 192.168.151.0.
- ATrue
- BFalse
20ARP is a protocol designed to obtain the IP address from the corresponding MAC address.
- ATrue
- BFalse
