Question 9 of 37

10. Which three methods are used by the transport layer to control data flow?

Question 10 of 37

11. If the ipv6 enable interface configuration command is issued under an interface, a Link-Local address is created automatically for that interface using EUI-64 addressing.

Question 11 of 37

12. SNMP  and FTP operate at which OSI layer?

Question 12 of 37

13. Each device connected to a central hub or switch is known as a ___ topology.

Question 13 of 37

14. In the first step of creating the EUI-64 address, the value ____  is inserted into the middle of the MAC address, thereby expanding the MAC address from 48 bits, which is 12 hexadecimal characters, to 64 bits, which is 16 hexadecimal characters.

Question 22 of 37

23. Layer 4 of the OSI model is also known as?

Question 23 of 37

24. With the ipv6 address command, the ___  keyword is used to configure an IPv6 address for an interface and enables IPv6 processing on the interface using an EUI-64 interface ID in the low-order 64 bits of the address.
