QUESTION 1
Every time a flap occurs on a route, the route receives_____

A. 750 per-flap penalty points which are user configurable B. 1500 per-flap penalty points which are user configurable C. 200 per-flap penalty points which are user configurable
D. 1000 per-flap penalty points which are not user configurable
E. 2000 per-flap penalty points which are not user configurable

Answer: D

Explanation: Everytime a flap occurs a penalty of 1000 is made and is not configurable. See sections on route dampening in Internet routing architectures guide.

QUESTION 2
Which component of MPLS architecture uses protocols such as the label distribution (LDP) and tag distribution protocol (TDP) to exchange labels?

A. Control pane
B. Data plane
C. Routing plane
D. Forwarding plane

Answer: A

QUESTION 3
Exhibit:

Which statement is true about packet forwarding across an MPLS VPN backbone?

A. Penultimate hop popping (PHP) on the LDP label is performed by the egress PE
router.
B. Penultimate hop popping (PHP) on the VPN label is performed by the second P router.
C. Penultimate hop popping (PHP) on the VPN label is performed by the egress PE
router.
D. Penultimate hop popping (PHP) on the LDP label is performed by the second P router.

Answer: D

QUESTION 4
What is a good definition of Cisco’s implementation of an ATM Virtual Path as related to LC-ATM MPLS support?

A. Designed to establish switch-to-switch connectivity between parts of a public ATM
network over a private network.
B. Designed to establish switch-to-switch connectivity between parts of a private ATM
network over a public network.
C. Designed to establish router-to-router connectivity between parts of a public ATM
network over a public network.
D. Designed to establish router-to-router connectivity between parts of a public ATM
network over a private network. Answer: B
QUESTION 5
What are two drawbacks when the Internet is accessed through a dedicated subinterface implementation? (Select two.)

A. The VRP will leak routes into the global routing table. B. The P router must run both IGP and BGP.
C. The PE routers must perform Internet routing
D. A limited set of Internet services will be implemented.
E. A separate physical link or specific WAN encapsulation is required.

Answer: C, E

QUESTION 6
Which three statements are correct regarding Layer 2 overlay VPNs and peer-to-peer VPNs? (Choose three.)

A. Peer-to-peer VPNs require the establishment of virtual circuits to connect the different customer sites together.
B. Peer-to-peer VPNs require the service provider to participate in the customer routing, accepting customer routes, transporting them across the service provider backbone, and finally propagating them to other customer sites.
C. With peer-to-peer VPNs, the service provider is responsible for transport of Layer 2
frames between customer sites, and the customer takes responsibility for all higher layers.
D. The implementation of Layer 2 overlay VPNs is the traditional switch-WAN model, implemented with technologies like X.25, Frame Relay or ATM.
E. With Layer 2 overlay VPNs, the service provider is not aware of customer routing has no information about customer routers.
F. It is simple to implement Layer 2 overlay VPNs because the Customer Edge (CE)

router just needs a connection to the Service Provider’s Edge (PE) router.

Answer: B, D, E

QUESTION 7
Exhibit:

What will the BGP configuration accomplish? (Choose two.)

A. Prefix 10.0.0.0/8 announced to neighbor 10.1.1.1. will have a MED of 100.
B. Prefix 10.0.0.0/8 announced to neighbor 10.1.1.1. will have a MED of 200.
C. All prefixes except the 10.0.0.0/8 prefix will not be announced to neighbor 10.1.1.1.
D. All prefixes except the 10.0.0.0/8 prefix announced to neighbor 10.1.1 will have a
MED of 0.
E. All prefixes except the 10.0.0.0/8 prefix announced to neighbor 10.1.1 will have a
MED of 200. Answer: A, E
QUESTION 8
Exhibit:

What is wrong with the BGP configuration in the exhibit? A. The auto-summary configuration is missing.
B. The network 10.0.0.0 statement is missing mask 0.255.255.255. C. The network 10.0.0.0 statement is missing mask 255.0.0.0
D. The network 192.168.0.0 statement is missing mask 255.255.0.0. E. The network 192.168.0.0 statement is missing mask 0.0.255.255
