1. True or False. RA messages are sent to all IPv6 routers by hosts requesting addressing information.
- True
- False
Explanation: The correct answer is False. Router Advertisement (RA) messages are sent to all IPv6 nodes. If Method 1 (SLAAC only) is used, the RA includes network prefix, prefix-length, and default-gateway information.
2. Which dynamic addressing method for GUAs is the one where devices rely solely on the contents of the RA message for their addressing information?
- Method 1: SLAAC
- Method 2: SLAAC and Stateless DHCPv6
- Method 3: Stateful DHCPv6
Explanation: SLAAC is a method where devices create their own GUA without the services of DHCPv6. Using SLAAC, devices rely on the local router ICMPv6 RA messages to obtain the necessary information.
3. Which dynamic addressing method for GUAs is the one where devices rely solely on a DHCPv6 server for their addressing information?
- Method 1: SLAAC
- Method 2: SLAAC and Stateless DHCPv6
- Method 3: Stateful DHCPv6
Explanation: Stateful DHCPv6 is a method where devices automatically receive their addressing information including a GUA, prefix length, and the addresses of DNS servers from a stateful DHCPv6 server.
4. Which dynamic addressing method for GUAs is the one where devices get their IPv6 configuration in a RA message and request DNS information from a DHCPv6 server?
- Method 1: SLAAC
- Method 2: SLAAC and Stateless DHCPv6
- Method 3: Stateful DHCPv6
Explanation: SLAAC and stateless DHCPv6 is a method where devices use SLAAC for the GUA and default gateway address. The devices then use a stateless DHCPv6 server for DNS servers and other addressing information.
5. What are the two methods a device can use to generate its own IPv6 interface ID?
- SLAAC
- stateless DHCPv6
- stateful DHCPv6
- EUI-64
- randomly generated
Explanation: When the RA message is either SLAAC or SLAAC with stateless DHCPv6, the client must generate its own interface ID using the EUI-64 process or a randomly generated 64-bit number.
