7. Which of the below are supported IPv6 unicast address types (Choose three)?

Unique local

Router local

Global unicast

link-local

8. Which of the below is NOT an EIGRP protocol message?

Hello

Update

Query

Request

9. When configuring EIGRP over frame-relay multipoint network in Hub-and-Spoke topology, EIGRP Hello messages aren’t forwarded by default by Hub router to Spokes. How can you solve this problem?

Configure IPsec tunnels between Hub and Spokes.

Enable broadcast over the frame-relay network.

Disable split-horizon on the multipoint sub-interface of the Hub router.

This problem can’t be solved for EIGRP over frame-relay.

10. Which command can be used to limit the amount of interface bandwidth used by EIGRP messages?

Router(config-if)#eigrp maximum bandwidth [percent]

Router(config-if)#eigrp message [percent]

Router(config-if)#ip eigrp limit [percent]

Router(config-if)#ip bandwidth-percent eigrp [asn percent]

11. Which of the below can the network administrator use to manipulate EIGRP metric?

Access list

Offset list

Prefix list

Route map

12. Which of the below is used in EIGRP to determines whether a route is a feasible successor?

Non-successor route’s RD is less than the FD

Successor route's RD is less than FD

Non-successor route's FD is less than the FD

Successor route's FD is less than RD

13. When EIGRP successor route fails on the router that doesn't have a feasible successor route, it moves to active state on that router. The router then tries to find other valid routes to the destination. To do so, it sends EIGRP Query messages to every neighbor except the neighbor that advertised this failed route.

Which of the below is valid action from these neighbors when they receive the Query message?

If the neighbor itself is active on this route, it immediately sends an EIGRP Reply back to the original router before waiting on replies to its own set of Query messages.

If the neighbor itself is active on this route, it does not forward the Query message to neighboring routers as it has no problem.

If the neighbor is passive on this route, it forward the Query message to neighboring routers.

If the neighbor is passive on this route, it sends an EIGRP Reply message, telling the original router that it does have a loop-free route.

14. What will an EIGRP router do when it receives an EIGRP Query for a prefix/prefix length and it only has a summary route that includes the prefix/prefix length?

It send a Query message to neighbor routers.

It insert the route in its routing table in ACTIVE state.

It immediately sends an EIGRP Reply and does not flood the Query to its own neighbors.

It doesn't reply to the sender as it doesn't have that prefix in its EIGRP database.

15. EIGRP uses a to filter routes by referencing an Access Control List (ACL), Prefix List, or Route Map.

16. Which of the below routes are matched by the prefix list (Choose two):
ip prefix-list FILTER seq 5 permit 10.0.0.0/8 ge 24 le 24?

10.128.0.0/9

10.128.10.8/30

10.1.1.0/24

10.1.2.0/24

17. Which of the below is correct about route-map logic when used for redistribution (Choose two)?

Routes matched by the match command in route-map with the permit option are allowed through.

The route-map includes an implied deny all clause at the end.

Routes matched by the match command in route-map with the deny option are allowed through.

Route-map clause can match by referring to an ACL but not prefix-list

18. Which of the below is correct about route summarization in OSPF and EIGRP?

OSPF doesn't support route summarization while EIGRP support route summarization.

EIGRP can summarize on any interface while OSPF can only summarize on area boundary.

When summarization is enabled, EIGRP router can's support route filtering.

OSPF and EIGRP summary routes can't be redistributed into another protocol.

19. Which command can be used to generate an EIGRP summary address on router?

Router(config)#ip summary-address [prefix] [subnet-mask]

Router(config-router)#ip summary [asn] [prefix] [subnet-mask]

Router(config-if)#ip summary-address eigrp [asn] [prefix] [subnet-mask]

Router(config-if)#ip summary-address eigrp automatically

20. When comparing EIGRP for IPv4 with EIGRP for IPv6, which of the below are correct (Choose two)?

Both EIGRP for IPv4 and EIGRP for IPv6 uses Successor, Feasible Successor logic.

EIGRP for IPv6 can perform automatic summarization.

EIGRP for IPv6 doesn't uses triggered updates.

EIGRP for IPv4 uses multicast update destination of 224.0.0.10

21. Which of the below are configuration modes of Named EIGRP (Choose three)?

Address-Family

Address-Family-Interface

Address-Family-Database

Address-Family-Topology

22. When configuring OSPF “passive-interface” command under an interface that has OSPF enabled on it, Which of the below is true?

The router will form neighbor relationship on that interface but will not advertise interface's network.

The router will stop sending Hello messages but will form neighbor relationship if it received Hello messages from neighbor router.

The router will not form neighbor relationship on that interface but will advertise the network of that interface

The router will not form neighbor relationship on that interface and will not advertise the network of that interface

23. Comparing OSPF to EIGRP, which of the below are correct about neighbor requirements for EIGRP and OSPF (Choose two)?

Interfaces’ primary IP addresses must be in same subnet for both OSPF and EIGRP.

Router IDs must be unique for both OSPF and EIGRP.

Interface must not be “passive” for both OSPF and EIGRP.

Must have same authentication in OSPF but not a must for EIGRP.

24. What happens when MTU setting differ on two neighboring OSPF routers?

The neighbor relationship will form but no routing information will be exchanged.

One router will be listed in the other router list of neighbors but will remain in EXSTART state

As MTU is not a requirement for OSPF neighbor relationship, they will form neighbor relationship and will be FULL neighbors.

They will both be stuck in EXCHANGE state.

25. Which of the below OSPF network types uses DR/BDR (Choose two)?

Broadcast

Point-to-Point

NBMA

Point-to-multipoint

26. Which of the below OSPF network types doesn't enable dynamic discovery of neighbors?

NBMA

Point-to-multipoint

Point-to-point

Broadcast

27. When configuring an OSPF Virtual Link, which of the below statements is correct?

The routing updates are tunneled through the Virtual Link, but the data traffic is sent natively

Both routing updates and data traffic are tunneled through the Virtual Link

A copy of routing updates is tunneled through the Virtual Link and another is sent natively to routers in non-backbone area.

When enabling Virtual Link, authentication must be configured to secure traffic passing through other areas.

28. Match each OSPF LSA type to its description.

Created by ASBRs inside an NSSA area, instead of a Type 5 LSA

Advertises a host route used to reach an ASBR

Created by ASBRs for external routes injected into OSPF

Created by each router to represent itself for the area to which it connects

Created by ABRs to represent subnets listed in one area’s Type 1 and 2 LSAs when being advertised into another area

Can send information about IPv6 networks attached to a router

Created by the DR on the subnet, and represents the subnet and the router interfaces connected to the subnet

Net Summary
ASBR Summary
Network
Intra-Area Prefix LSAs
Router
NSSA External
AS External

eBGP
OSPF
Internal EIGRP
RIP
iBGP

LSA Type 1
LSA Type 2
LSA Type 4
LSA Type 5
