| Question ID 14471 | Which two of these statements are true of IPv6 address representation? (Choose two.)
|
| Option A | There are four types of IPv6 addresses: unicast, multicast, anycast, and broadcast.
|
| Option B | A single interface may be assigned multiple IPv6 addresses of any type.
|
| Option C | Every IPv6 interface contains at least one loopback address.
|
| Option D | The first 64 bits represent the dynamically created interface ID.
|
| Option E | Leading zeros in an IPv6 16 bit hexadecimal field are mandatory.
|
| Correct Answer | B,C |
Explanation Explanation: A single interface may be assigned multiple addresses of any type (unicast, anycast, multicast). Every IPv6-enabled interface must contain at least one loopback and one link-local address. Optionally, every interface can have multiple unique local and global addresses. IPv6 host addresses can be assigned in multiple ways: Static configuration Stateless autoconfiguration DHCPv6 When IPv6 is used over Ethernet networks, the Ethernet MAC address can be used to generate the 64-bit interface ID for the host. This is called the EUI-64 address. Since MAC addresses use 48 bits, additional bits must be inserted to fill the 64 bits required.

| Question ID 14472 | What is the OSPF default frequency, in seconds, at which a Cisco router sends hello
packets on a multi-access network?
|
| Option A | 10
|
| Option B | 40
|
| Option C | 30
|
| Option D | 20
|
| Correct Answer | A |
Explanation Explanation: On broadcast multiacess and point-to-point links, the default is 10 seconds. On NBMA, the default is 30 seconds.
