Question No: 31
Refer to the exhibit. A network engineer from ISP 2 is designing the BGP architecture with a requirement of preventing their customer AS 65001 from becoming a transit AS, using the following configuration.
Router BGP 65000
Neighbor 10.0.0.1 remote-as 65001
Neighbor 10.0.0.1 route-map BGP-ROUTE-policy in
Which Cisco IOS command should be used within the route-map to achieve the goal on ISP 2 from AS 65000?
route-map BGP-ROUTE-POLICY permit 10 set community no-advertise additive
ip as-path access-lists 1 permit^65001$
route-map BGP-ROUTE-POLICY deny 10 match as-path 1
route-map BGP-ROUTE-POLICY permit 10
ip as-path access-list 1 permit^65001$
route-map BGP-ROUTE-POLICY permit 10 match as-path 1
route-map BGP-ROUTE-POLICY permit 10 set community no-export additive

MPLS TE autoroute announce
Question No: 33

All intra-area routes are converted to external routes
All interarea routes are lost
All intra-area routes are converted to interarea routes
AU intra-area routes are lost
Question No: 34
Which protocol functions as the transfer protocol between the Cisco Open SDN Controller and forwarding devices?

Access port only Filtering of BPDUs S-NNI
Trunk port only
Support S-Vlan BPDU, however only encapsulation default is supported
Question No: 38
Which two steps take place in the BGP Link State architecture ? (Choose two)
IGP is redistributed into BGP-LS
Advertise the BGP-LS NLRIs to the topology server
IGP uses BGP LS data from remote peers
Enable access to the Adj-RIB-In (BGP raw format )of a peer border router or provider edge router
BGP downloads the received BGP LS data to the IGP component on the router
Question No: 39
Which protocol in the IPv6 stack does the MLD protocol use to carry its messages?
Question No: 40
ISP A provides L2VPN services to Company B through an MPLS network. Company B uses all available CoS values to classify and different traffic forwarding within all Company B sites. ISP A uses the following CoS values to differentiate service classes for the VPN customer traffic
*MPLS EXP 0 for Bronze service class
*MPLS EXP 1 for Silver service class
*MPLS EXP 2 for Gold service class
*Remaining MPLS EXP values for ISP A internal use
ISP A’s policy is to forward VPN customer traffic based only on their Bronze, silver and Gold service classes. Which QoS method must ISP A implement to achieve this?
Russian Doll Model
