Q2. Due to recent acquisitions, a company’s MPLS infrastructure is growing very quickly. Concerns arise about labeling each and every IP address on the P router. Which command would significantly reduce the label allocations without compromising LDP functionalities?
A. ip prefix-list List1 deny prefix/prefix_length
!
mpls ldp label
allocate global prefix-list List1
B. mpls ldp label
allocate global host-routes
C. access-list 1 permit subnet wildcard
mpls ldp neighbor neighbor_ip labels accept 3
D. mpls ldp password required for 10
access-list 10 permit host_ip_1
access-list 10 permit host_ip_2
access-list 10 permit host_ip_n
Answer: A
Q3. Two switches are connected back-to-back using two Gigabit Ethernet interfaces. These two interfaces are assigned to a port channel in VLAN trunk mode. Which configuration sequence allows the addition of a new VLAN in this link?
A. Add the VLAN to the port channel only, and remove it from the individual links.
B. Add the VLAN to both the port channel and individual links.
C. Add the VLW to the port channel only, and it will be reflected on the individual links.
D. Add the VLAN to the individual links, and it will be reflected on the port channel.
Answer: C
Q4. 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?

!
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
Q5. Which two statements about forwarding equivalence class (FEC) are true? (Choose two)
A. FEC might correspond to a destination IP subnet, but it might also correspond to any traffic class that the edge LSR considers significant.
B. FEC is a group of IP packets that is forwarded over a different path, but with the same forwarding treatment.
C. FEC is a group of IP packets that is forwarded over the same path, and with the same forwarding treatment.
D. FEC is a group of IP packets that is forwarded over a different path, but with the different forwarding treatment.
E. FEC is a group of IP packets that is forwarded over the same path, but with a different forwarding treatment.
Answer: A,C
Q6. Refer to the exhibit. Two MPLS TE tunnels are configured with a total bandwidth guarantee of 100 Mbps. However, Tunnel 1 has a requirement to have one-fifth of this total bandwidth. Which two configurations accomplish this goal? (Choose two.)

B. Configure bandwidth 20000 under the Tunnel 1 interface.
C. Configure tunnel mpls traffic-eng bandwidth 80000 under the Tunnel 2 interface.
D. Configure bandwidth 80 Mbps under physical interfaces in the path PE1-P2-PE2.
E. Configure bandwidth 20 Mbps under physical interfaces in the path PE1-P1-PE2
