  Which protocol supports labeled paths between PE routers in an MPLS network?

  A. LDP
  B. RSVP
  C. MP-BGP
  D. IGP
  C. MP-BGP

  ---

  In an MPLS network, Service Provider Edge (PE) routers use Multiprotocol Border Gateway Protocol (MP-BGP) to exchange label and route information with each other. MP-BGP is the routing protocol used to create and distribute labels between service provider edge routers on an MPLS network.

• Question 43:

  A. RD is prepended to the IPv4 route to make it unique.
  B. The VPNv4 address consists of a 64-bit route distinguisher that is prepended to the IPv4 prefix.
  C. MP-BGP is used to allow overlapping IPv4 addresses between customers to advertise through the network.
  D. The IPv4 address is needed to tag the MPLS label.
  E. The VPNv4 address is used to advertise the MPLS VPN label.
  A. RD is prepended to the IPv4 route to make it unique.
  E. The VPNv4 address is used to advertise the MPLS VPN label.

• Question 46:

  Refer to the exhibit.

  

  The none area 0 routers in OSPF still receive more specific routes of 10.1.1.0.10.1.2.0.10.1.3.0 from area 0. Which action resolves the issue?

  A. Configure route summarization on OSPF-enabled interfaces.
  B. Summarize by using the summary-address 10.1.0.0 255.255.252.0 command.
  C. Summarize by using the area range command on ABRs
  D. Configure the summary-address 10.1.0.0 255.255.252.0 command under OSPF process.
  C. Summarize by using the area range command on ABRs

• Question 47:

  Which of the following translation scenarios is NOT supported by stateless NAT64?

  A. translation from IPv6 Internet to an IPv4 network
  B. translation from IPv4 Internet to an IPv6 network
  C. translation from IPv6 network to an IPv4 network
  D. translation from IPv4 network to an IPv6 network
  A. translation from IPv6 Internet to an IPv4 network

  ---

  Translation from IPv6 Internet addresses to an IPv4 network is not supported by the stateless version of NAT64. There are two versions of NAT 64: stateful and stateless. Stateful NAT64 creates or modifies bindings or session state while performing translation, while stateless NAT64 does not create or modify bindings or session state while performing translation/ Translation from IPv4 Internet to an IPv6 network is supported by both NAT64 methods, although the stateful version requires static 6 to 4

  mappings.

  Translation from an IPv6 network to an IPv4 network is supported by both methods, stateful and stateless.

  Translation from an IPv4 network to an IPv6 network is supported by both methods, although the stateful version requires static 6-to-4 mappings.

  Which action resolves the IP SLA for the UDP jitter problem between R4 and R3 Ethernet 0/1 IP addresses?

  A. Delete and configure the ip sla 6500 command with R3 e0/1 IP address.
  B. Configure the ip sla 6500 command with R3 e0/1 IP address.
  C. Configure the ip sla responder command with R4 E0/1 IP address.
  D. Delete and configure the ip sla responder command with R4 E0/1 IP address.
  A. Delete and configure the ip sla 6500 command with R3 e0/1 IP address.

• Question 50:

  You have implemented OSPF for IPv6 for the following areas in OSPF AS 1:

  

  The cost from rtrB to the 2001:5050:D402:B333:1:FE30::/96 network is 80, while the cost from rtrB to the 2001:5050:D402:B333:2:FE59::/96 network is 130. Which of the following area range cost commands should be executed on rtrB?

  A. area 10 range 2001:5050:D402:B333::/64 cost 80
  B. area 10 range 2001:5050:D402:B333::/64 cost 130
  C. area 10 range 2001:5050:D402:B333::/64 cost 210
  D. area 10 range 2001:5050:D402:B333::/64 cost 0
  B. area 10 range 2001:5050:D402:B333::/64 cost 130

  ---

  The area 10 range 2001:5050:D402:B333::/64 cost 130 command should be executed on rtrB. This command defines an area range for an area border router (ABR) that has OSPF for IPv6 enabled on it. This command provides a summary route of the routes in an OSPF area to be distributed to another area.

  The range keyword in the command provides the summary route. The cost keyword in the command specifies the cost of the summary route. The highest cost of the routes that are being summarized becomes the cost of the summary route. In this case, the cost from rtrB to the 2001:5050:D402:B333:1:FE30::/96 network is 80, and the cost from rtrB to the 2001:5050:D402:B333:2:FE59::/96 network is 130. The cost of the summary route is 130 as it is higher.

  All the other options are incorrect because they do not specify the correct cost of the summary route.
