-
How do you minimize the bandwidth requirement for EIGRP packets?
- By propagating only data packets
- By propagating only hello packets
- By propagating only routing table changes and hello packets
- By propagating the entire routing table only to those routers that are affected by a topology change
-
Which command correctly specifies that network 10.0.0.0 is directly connected to a router that is running EIGRP?
- Router(config)# network 10.0.0.0
- Router(config)# router eigrp 10.0.0.0
- Router(config-router)# network 10.0.0.0
- Router(config-router)# router eigrp 10.0.0.0
-
Which command displays the amount of time since the router heard from an EIGRP neighbor?
- show ip eigrp traffic
- show ip eigrp topology
- show ip eigrp interfaces
- show ip eigrp neighbors
-
Which command must you configure for EIGRP to pass the subnet mask with the route?
- ip classless
- no auto-summary
- no summary
- ip subnet vlsm
-
Which command displays whether route filtering has been enabled?
- show interface
- show access-list
- show ip protocols
- show route-filter
-
Which form of authentication does EIGRP support?
- Plain text
- 3DES
- MD5
- Both A and C
-
What does the EIGRP message "neighbor not on common subnet" mean?
- Duplicate EIGRP router IDs exist.
- The two adjacent neighbor interfaces do not have addresses in the same IP network.
- The MTU sizes on the two adjacent neighbor routers do not match.
