Q33. 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

Q39. Refer to the exhibit. A web server is connected to a switch via two Gigabit Ethernet links. These two links are bundled into a single logical link that provides the aggregate bandwidth of 2 Gbps. The support engineer notices that traffic from the Internet to the web server uses both Gigabit Ethernet links. However, traffic from the web server to the Internet uses only one link.

Answer: D
Q40. Two MPLS VPN customers want to acquire Internet access. They make use of overlapping address space but do not want to use NAT on the CPEs. Which action satisfies this requirement?
A. Configure each VRF with a default route in the global table by using a static route toward each customer's range, pointing to the customer interface in the global table.
B. Configure VRF-aware NAT with a default route in the global table for each VRF that requires it
C. Configure a separate PE-CE subinterface that terminates in the global routing table on the PE.
D. Configure the Internet upstream interface inside a VRF, Which becomes an extranet VRF to which customers join and make use of NAT in this VRF.
Answer: D
