A. carrier detect
B. UDLD
C. BFD
D. CFM
Answer: D
Q42. Due to recent acquisitions, a company's MPLS infrastructure is growing very quickly. Concerns anse about labeling service provider core network The IP address space is designed as per following:
. Service provide ip address range is: 10.0.0.0/16
. All loopback 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 command would significantly reduce the label allocations without compromising LDP functionalities?
A. mpls Idp label
allocate global host-routes
B. ip prefix-list List1 deny 10.0.0J16 le 20 ge 25
!
mpls Idp label
allocate global prefix-list List1
C. access-list 1 permit 10.0.0.0.0.0.255.255
mpls Idp neighbor 10.0.0.1 labels accept 3
D. mpls Idp password required for 10
!
access-list 10 permit 10.0.0.1
access-list 10 permit 10.0.0.2
access-list 10 permit 10.0.0.3
Answer: A

Answer: E
Q45. A Service Provider connects to a client site that has two CEs. These CEs have a backdoor link for backup. OSPF is used as the routing protocol in this environment. You want to ensure that client traffic prefers the service provider connections for routing instead of the secondary connection. Which option describes the default behavior and the action that accomplishes your goal?
A. The routes to the Service Provider are not preferred, due to the increased OSPF cost through the service provider network. Ensure that the cost on the links to the service provider are lower than the secondary connection.
B. The routes to the Service Provider are seen as external type 1 in the OSPF database. Configure a domain ID that is the same across all PEs, to ensure that customers see routes as intra-area.
C. The routes to the Service Provider are seen as inter-area OSPF routes through the network. Configure a sham link to create a new intra-area path across the service provider network between the PE routers that service the client.
D. The routes to the Service Provider are seen as equal and cause nondeterministic traffic patterns. Ensure that the secondary connection has a higher cost than the links to the service provider.
Answer: C

Q47. In an MPLS VPN environment, the QoS marking over the MPLS backbone must be different from the one that is received from the customer. The forwarding on the egress PE is based on the marking that is set by the ingress PE. Which null label and QoS mode can achieve this?

B. MPLS implicit null with short pipe mode
C. MPLS implicit null with uniform mode
D. MPLS explicit null with uniform mode
E. MPLS explicit null with short pipe mode
F. MPLS implicit null with pipe mode

Q49. In which way does the DS-Lite IPv6 transitioning mechanism differ from IPv6 Dual-Stack?
A. DS-Lite is a combination of tunnel and translation technologies.
B. DS-Lite is a transition technology that gives full IPv6 connectivity for IPv6 capable hosts that are on the IPv4 Internet but have no native connection to an IPv6 network.
C. DS-Lite is an automatic tunnel where the tunnel destination is determined by the IPv4 address extracted from the IPv6 address that starts with the prefix 2002::/16.
D. DS-Lite is a stateless tunneling mechanism with a lightweight and secure manner without requiring upgrades to existing IPv4 access network infrastructure.
