A. Guard mode

B. Closed mode

문제4

How does MPLS Layer 3 VPN function?

A. When a destination PE device receives a labeled packet, it pops the label and uses it to forward
the packet to the correct CE device.

B. When a PE device forwards a packet received from a CE device across the provider network, it
labels the packet with the label learned from the source PE device.

C. When a VPN route is learned from a CE device and injected into IGP, a VPN route distinguisher
attribute is associated with it.

D. When an EIGRP internal route is redistributed into BGP by one PE and then back into EIGRP by
another PE, the originating router ID for the route is changed to the router ID of the first PE.

정답: A

문제8

A. RA messages are allowed from the host port to the switch.

B. It is unable to protect tunneled traffic.

C. It is supported on the egress direction of the switch.

정답: D

문제9

Refer to the exhibit. An engineer must configure PBR on R1 to reach to 10.2.2.0/24 via R3
AS64513 as the primary path and a backup route through default route via R2 AS64513. All BGP
routes are in the routing table of R1, but a static default route overrides BGP routes.
Which PBR configuration achieves the objective?

A. access-list 100 permit ip 10.1.1.0 0.0.0.255 10.2.2.0 0.0.0.255
!
route-map PBR permit 10
match ip address 100
set ip next-hop recursive 10.3.3.1

B. access-list 100 permit ip 10.1.1.0 0.0.0.255 10.2.2.0 0.0.0.255
!
route-map PBR permit 10
match ip address 100
set ip next-hop 10.3.3.1

C. access-list 100 permit ip 10.1.1.0 255.255.255.0 10.2.2.0 255.255.255.0
!
route-map PBR permit 10
match ip address 100
set ip next-hop 10.3.3.1

D. access-list 100 permit ip 10.1.1.0 255.255.255.0 10.2.2.0 255.255.255.0
!
route-map PBR permit 10
match ip address 100
set ip next-hop recursive 10.3.3.1
