5. Which two statements describe features of EIGRP implemented for IPv4 and IPv6? (Choose two.)
- EIGRP for IPv4 does not require the no shutdown command in router configuration mode.
- EIGRP for IPv6 uses a 32-bit router-id.
- EIGRP for IPv6 does not require the same autonomous system number to be used between two neighboring EIGRP routers.
- EIGRP for IPv6 does not use the passive-interface command within router configuration mode.
- EIGRP for IPv4 is enabled by theip unicast-routing global configuration mode command.
6. How does EIGRP for IPv6 select a router ID if the router ID is not manually configured?
- It uses the highest link-local address that is configured on an active EIGRP for IPv6 interface.
- It is uses the EUI-64 process to automatically generate the router ID based on the highest configured IPv6 address value.
- It uses the highest IPv6 address that is configured on any enabled EIGRP for IPv6 interface.
- It uses the highest IPv4 address that is configured on an operating interface.
7. Which two aspects of the configuration of EIGRP for IPv6 differ from its configuration for IPv4? (Choose two.)
- For IPv6 no router ID is required for the EIGRP routing process to start.
- No network command is needed to enable EIGRP for IPv6.
- IPv6 requires a global unicast address on EIGRP interfaces.
- For IPv6, the autonomous system values on routers in a domain running EIGRP do not have to match.
- EIGRP on IPv6 is configured directly on router interfaces.
8. Which address is used by an IPv6 EIGRP router as the source for hello messages?
- the 32-bit router ID
- the IPv6 global unicast address that is configured on the interface
- the all-EIGRP-routers multicast address
- the interface IPv6 link-local address
9. What operational feature is different for EIGRP for IPv6 compared to EIGRP for IPv4?
- DUAL algorithm calculations
- the type of value used for the router ID
- neighbor discovery mechanisms
- the source and destination addresses used within the EIGRP messages
10. An administrator is troubleshooting a neighbor relationship issue between two routers in an EIGRPv6 network. The administrator suspects that the k values are mismatched. What command can be used to view the k values?
- show ipv6 protocols
- show ipv6 eigrp interfaces detail
- show ipv6 eigrp interfaces
- show key chain
11. An administrator is troubleshooting a router that has an interface that is not participating in the EIGRPv6 process? The administrator suspects that this might be because of a passive interface. What command can be used to verify this theory?
- show ipv6 eigrp interfaces
- show ipv6 eigrp interfaces detail
- show ipv6 protocols
- show ipv6 route
12. An administrator is troubleshooting authentication between two routers in an EIGRPv6 network. The administrator wants to check to ensure that authentication has been enabled and to verify that the key ID and key string are not mismatched between the two routers. Which two commands can be used to get this information? (Choose two.)
- show ipv6 eigrp interfaces detail
- show ipv6 protocols
- show key chain
- show ipv6 eigrp neighbors
- show ipv6 eigrp interfaces
