Demo Questions

Question 1
  

Refer to exhibit. A network engineer has a requirement to enable MPLS TE tunnels on the network to be used by L3VPN customers. Which MPLS TE feature allow the network engineer to configure MPLS TE LSPs by using a few CLI commands?

  • A: AutoTunnel Mesh Groups on all PE routers
  • B: AutoTunnel Mesh Groups on all P and PE routers
  • C: AutoTunnel Primary and Backup on all P and PE routers
  • D: AutoTunnel Primary and Backup on all P routers



Question 2
An MPLS network infrastructure of the service provider ABC is growing very quickly due to many recent acquisitions. Concerns arise about labeling each and every IP address on the service provider core network. The IP address pace is designed as per following:
Service provide ip address range is: 10.0.0.0/16
All loopbacks addresses use subnet mask /32 
10.0.0.0/24 range is used for loopback addresses 
All other subnet masks used for links are /24 and /25 
Which configuration does significantly reduce the label allocations without compromising LDP functionalities?

  • A: ip prefix-list List1 deny 10.0.0.0/16le 20 ge 25!mpls ldp label allocate global prefix-list List1
  • B: access-list 1 permit 10.0.0.0.0.0.255.255mpls ldp neighbor 10.0.0.1 labels accept 3
  • C: mpls ldp password required for 10!access-list 10 permit 10.0.0.1access-list 10 permit 10.0.0.2access-list 10 permit 10.0.0.3
  • D: mpls ldp label allocate global host-routes



Question 3
LDP uses which two components to discover neighbors on a network segment? (Choose two.)

  • A: 224.0.0.1multicast address
  • B: 646 udp port
  • C: 646 tcp port
  • D: 224.0.0.14 multicast address
  • E: 711 tcp port
  • F: 711 udp port
  • G: 224.0.0.2 multicast address



Question 4
  

Refer to the exhibit. R1 and R5 routers are not directly connected. Loopback 0 is configured as LDP router id for both R1 and R5 routers. Loopback 0 IPv4 addresses are reachable between R1 and R5 routers. The LDP session between R1 and R5 is not established. There is no access-list applied in any routers in the path between R1 and R5. Which is the reason the LDP session is not working?

  • A: LDP authentication are missing in both R1 and R5 routers.
  • B: Targeted LDP works only for directly connected LDP neighbors.
  • C: R5 is not configured to accept targeted LDP sessions.
  • D: It is necessary to create a GRE tunnel between R1 and R5 in order to targeted LDP session to work for a non directly connected LDP neighbors.



Question 5
Which feature allows an MPLS TE tunnel to be used by an IGP at the headend of the tunnel?

  • A: generalized MPLS
  • B: MPLS TE link management
  • C: Differentiated Services Traffic Engineering
  • D: MPLS TE autoroute announce
  • E: MPLS TE Forwarding Adjacency



Question 6
Refer to the exhibit. Which technology is being implemented? 

  

  • A: DS-TE
  • B: PBTS
  • C: IP FRR
  • D: CBTS



Question 7
 
 
Refer to the exhibit. Which statement is true about what this AS filter accomplishes?

  • A: It filters incoming BGP updates with an AS number matching “5.5”, but not 515, 525.535, etc, and this only in an AS_SET.
  • B: It allows any AS number with the statement “.*” and this only in an AS_SET
  • C: It filters incoming BGP updates with any AS number starting with the digit 5 and ending with the digit 5, and this only in an AS_SET.
  • D: It filters incoming BGP updates with any AS number starting with the digit 5 and ending with the digit 5, and this only in an AS_PATH.



Question 8
  

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 two Cisco IOS command should be used within the route-map to achieve this goal on ISP 2 from AS 65000?

  • A: ip as-path access-list 1 permit ^65001$!route-map BGP-ROUTE-POLICY deny 10match as-path 1!route-map BGP-ROUTE-POLICY permit 10
  • B: ip as-path access-list 1 permit ^65001$!route-map BGP-ROUTE-POLICY permit 10match as-path 1
  • C: route-map BGP-ROUTE-POLICY permit 10set community no-export additive
  • D: route-map BGP-ROUTE-POLICY permit 10set community no-advertise additive



Question 9
Which protocol provides an alternative to the STP, which provides a way to control network loops, handle link failures, and improve convergence time and can coexist with STP?

  • A: IEEE 802.1ah
  • B: Flex Links
  • C: E-TREE
  • D: PBB-EVPN
  • E: REP



Question 10
Which three configuration sections are required on service provider PE routers to enable IPv4 Layer 3 VPN? (Choose three.)

  • A: Implement MPLSfor all customer-facing links.
  • B: Configure route targets that are used for importing and exporting customer VRF routers.
  • C: Advertise customer routes to all PE routers by configuring the IPv4 address-family under the MP-BGP configuration mode.
  • D: Configure at least one interface that is assigned to a customer link as a member of the VRF
  • E: Configure the VPNv4 address-family under the MP-BGP configuration mode on the PE routers that participate in the customer VRF routing
  • F: Configure route distinguishers that are used for importing and exporting customer VRF routes
