You are currently learning about networking devices and have just learned about MAC addresses. You look up your device's MAC address, and it comes back as 00-B0-D0-06-BC-AC. Which portion of this MAC address can tell you who the manufacturer is?
00-B0-D0 The first half (first six digits) of a MAC address is assigned to each manufacturer by the Institute of Electrical and Electronic Engineers (IEEE). The rest of the MAC address consists of a unique, randomly generated value.
Which of the following are valid IPv6 addresses? (Select two.)
141:0:0:0:15:0:0:1 6384:1319:7700:7631:446A:5511:8940:2552 An IPv6 IP address is a 128-bit address listed as eight 16-bit hexadecimal sections. Leading 0s can be omitted in each section. 6384:1319:7700:7631:446A:5511:8940:2552 is a valid IPv6 IP address. A single set of all-zero sections can be abbreviated with two colons (::). 141::15:0:0:1 would also be a valid way of writing that address.
Which of the following correctly describe the most common format for expressing IPv6 addresses? (Select two.)
32 numbers, grouped using colons Hexadecimal numbers
You are working as a junior technician for a small consulting firm. You have been tasked with installing a new computer on the network. You have performed this task and connected the computer to the network. To verify network connectivity, you decide to ping the network server. Before this can happen, the new device needs to know the MAC address of the network server so it can match it to the IP address. The computer sends a broadcast message, asking who has the IP address. The network server responds with its MAC address, and now the computer can communicate with the server. Which protocol is being used when sending the broadcast message to match the MAC address to the IP address?
ARP
You are the IT technician for your company. Which of the following mechanisms would BEST allow you to resolve a hostname to its associated IP address? (Select two.)
DNS and host file. DNS can be used to get the IP address from a given hostname. you can also use the local hosts file to map hostsnames to IP addresses
You have a small home network that uses 192.168.1.0 with the default subnet mask for the network address. The default gateway address is 192.168.1.254, and the router is providing DHCP on the network. The Wrk2 computer has been assigned the IP address of 192.168.1.55. Which of the following is considered the loopback address for the Wrk2 computer?
127.0.0.1 is the loopback address for any device
Which of the following IP addresses are Class B addresses? (Select three.)
129.0.0.0 132.12.0.0 190.65.2.0
Which of the following IP addresses have a default subnet mask of 255.255.0.0? (Select three.)
129.0.0.1 191.168.2.15 168.16.5.1 to identify an IP address's class look at the first octet. Class A networks use a default subnet mask of 255.0.0.0 and have numbers between 0 and 126 in their first octet. Class B networks use a default subnet mask of 255.255.0.0 and have numbers between 128 and 191 as their first octet. Class C networks use a default subnet mask of 255.255.255.0 and have numbers between 192 and 223 as their first octet. In this question, the IP addresses that fall in the Class B IP address range are 191.168.2.15, 129.0.0.1, and 168.16.5.1.
Your Windows workstation has Automatic Private IP Addressing (APIPA) implemented with default settings. Which of the following TCP/IP addresses could you automatically assign to the system, should your DHCP server go down or become inaccessible?
169.254.1.26
Which of the following identifies the interface ID component of an IPv6 address? (Select two.)
The last 64 bits of an IPv6 address. The last four quartets of an IPv6 address An IPv6 address is a 128-bit binary number that uses the first 64 bits as the address prefix and the last 64 bits of the address as the interface ID. The 128-bit binary number is organized into 32 hexadecimal numbers that are organized further into eight quartets. The last four quartets correspond with the last 64 bits of the IPv6 address.
