You recently joined a company as a junior-level network administrator. You have been tasked with designing the IPv4 scheme for five networks that will be used for training classrooms. These networks need to support no more than 28 devices each. Due to the existing network design, the senior-level network administrator has asked you to work on network 192.168.40.0/24.
If all networks must be made to logically start with the lowest numbered network and end with the largest numbered network, what is the network ID for the third network?
A. 192.168.40.32/27
B. 192.168.40.64/27
C. 192.168.40.96/27
D. 192.168.40.128/27
Which IPv6 scope is used for private addressing on a local network?
A. Global
B. Area wide
C. Unique local
D. APIPA
Which Ethernet frame forwarding method works best when the outbound ports run at the same speed as the inbound port?
A. Store-and-forward
B. Fragment-free
C. Unicast
D. Cut-through
What accurately describes IPv6 addressing?
A. IPv6 addresses are denoted by eight groups of four hexadecimal numbers.
B. IPv6 uses 128 hexadecimal numbers instead of the 32 hexadecimal numbers used by IPv4.
C. IPv6 is used to converse IP addresses and utilize private addresses.
D. IPv6 uses broadcast addresses for neighbor discovery.
What does the switch do with the frame?
A. Flushes the destination MAC address and updates the MAC address table in the switch.
B. Adds the source MAC address and port to the MAC address table and forwards the frame.
C. Discards the frame on all ports and sends an error message back to the host.
D. Floods the frame to all ports except for the port the frame originated from to locate the source MAC address.
Which IP address is in the Class B range?
A. 100.100.90.87
B. 126.16.20.48
C. 191.56.44.200
D. 192.15.48.130
