Q31. Due to recent acquisitions, a company's MPLS infrastructure is growing very quickly. Concerns arise about labeling each and every IP address on the 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. ip prefix-list Llst1 deny 10.0.0./16 le 20 ge 25
!
mpls Idp label
allocate global prefix-list List1
B. access-list 1 permit 10.0.0.0 0.0.255.255
mpls Idp neighbor 10.0.0.1 labels accept 3
C. mpls Idp label
allocate global host-routes
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: C
Q32. Two Tier 2 Service Providers are using a Tier 1 Service Provider for transport. MPLS is required between the Tier 2 Service Providers for label switching. In this CSC solution, which label stack is correct?
A. original IP packet, MPLS CSC transport label, MPLS VPN label, and MPLS Tier 2 transport label
B. original IP packet, MPLS Tier 2 transport label, MPLS VPN label, and MPLS CSC transport label
C. original IP packet, MPLS VPN label, MPLS Tier 2 transport label, and MPLS CSC transport label
D. original IP packet, MPLS Tier 2 transport label, MPLS CSC transport label, and MPLS VPN label
Answer: C

D. EVC
E. EPL
Answer: A,E

Q34. Refer to the exhibit.
A CE connected to a service provider has an agreement to use 512Mbps of bandwidth. Which QoS configuration must be modified to ensure that the traffic matches the agreed bandwidth?
A. Apply the same CE QoS configuration on PE on inbound direction.
B. Change the outbound direction of the service-policy to inbound for ingress traffic shaping.
C. Treat the class-default as best-effort by removing the shape average 512000 command
D. Replace the shape keyword with police keyword in both classes
E. Reconfigure the policy-map as a nested policy with the shaping applied as a parent for all child policies
Answer: E
Q35. A Service Provider is offering VoIP services and a service level agreement to customers. Which configuration provides validation to customers that the service level agreement has been honored?
A. ip sla 999 udp-jitter 209.165.200.225 1000 codec g729a tos 160 ip sla schedule 999 life forever start-time now
B. ip sla 999 icmp-jitter 209.165.200.225 tos 160 ip sla schedule 999 life forever start-time now
C. ip sla 999 icmp-jitter 209.165.200.225 tag VoIP-SLA ip sla schedule 999 life forever start-time now
D. ip sla 999 udp-jitter 209.165.200.225 1000 codec g729a tag VoIP-SLA
ip sla schedule 999 life forever start-time now

Q36. A company is deciding between an HVR and SVR solution in order to finalize a virtualization project proposal. Which is an advantage of a HVR solution versus a SVR solution?
A. A HVR solution implements dedicated data plane resources.
B. A HVR solution implements shared control plane resources.
C. A HVR solution introduces significant contention of resources.
D. A HVR solution implements dedicated chassis resources.
Answer: A
Explanation:
Comparison of Virtualized Routing Architectures
Category Hardware-Isolated Virtual Router Software-Isolated Virtual Router
Control plane resources (CPU, memory)
Dedicated
Shared
Data plane resources (forwarding engine, queues)
Dedicated
Shared
Chassis resources (power supplies, blowers, fabric)
Shared
Shared
Management, configuration
Dedicated
Typically shared, but varies depending on degree of virtualization
Connections between virtualized routing entities
Typically external
Typically internal, but possibly external
Per-chassis scalability (routing adjacencies, prefixes)
Increased with additional logical routers
Unaffected by additional virtual routers

Q37. Refer to the exhibit.
What is the status of the L2 tunnel between PE1. PE2. and the Layer 2 switches?
A. The Layer 2 tunnel is up, and SW1 becomes the root bridge for VLAN 10.
B. The Layer 2 tunnel is down, due to the ACL that is applied on the PE2 interface.
C. The Layer 2 tunnel is up, but no BPDUs are exchanged unless an extra configuration is applied.
D. The Layer 2 tunnel is down, due to the MTU mismatch between SW1 and SW2.
Answer: A
Q38. What is the main advantage of H-VPLS over VPLS?
A. H-VPLS provides redundancy.
B. H-VPLS provides security.
C. H-VPLS improves the scalability.
D. H-VPLS allows a broader use of protocols.

Q39. A telecom company offers ISPs the ability to resell dynamic IP broadband services over its local loops, but it does not allow the resellers to install broadband network gateways. If an ISP wants to become a reseller but is unable to use NHRP, which tunneling protocol should be implemented?
A. IP in IP
B. IPsec
C. L2TP
D. GRE
Answer: C
Explanation:
However, while OpenVPN can not be used with VoIP, L2TP can be used for VoIP. Only use this if OpenVPN is not available and you are in need of very high security/encryption.
Q40. An engineer has just configured IOS-XR with out-of-band MPP. Which are the three results that will occur? (Choose three.)

B. RP/DRP Ethernet Interfaces are not default out-of-band interfaces.
C. MPP configuration changes doesn’t affect active sessions established before the changes
D. Interfaces configured for out-of-band MPP are still part of global routing/forwarding
E. If MPP is disabled and a protocol is activated, all interfaces cannot pass traffic
F. LPTS will provide rate limiting
