Q11. Refer to the exhibit.
When a traceroute is performed from a PC behind R2, the next hop on R1 for IPv4 is 10.0.1.2, and for IPv6 it is 2001:DB8:2:2. What is causing thus behavior?
A. GigabitEthernet2/1 has a Level 1-only adjacency. This causes it to be the preferred path for the IPv6 packets.
B. When SPF ran on R2, it calculated two equal paths to R1. It was a coincidence that than the packets choose different paths.
C. Multitopology is enabled on R2, which causes the IPv6 packets to use a different path than the IPv4 packets.
D. 2001:DB8:2::2 is on a Gigabit Ethernet interface. Because its speed is higher than Fast Ethernet, the IS-IS metric is preferred.
Answer: C
Q12. Refer to the exhibit.
Which MPLS TE component keeps track of the flooding and admission control?
A. MPLS TE priorities
B. RSVP
C. link attributes
D. link manager
Answer: B
Q13. Refer to the exhibit.
A service provider is using the configuration to determine traffic paths based on MPLS EXP markings. Which technology is being implemented?
A. MPLS TE FRR
B. CBTS
C. IP FRR
D. MPLS TE
E. PBTS
F. DS-TE
Answer: B
Q14. In a virtualization concept, which is one of the characteristic of the HVR solution? A. introduces significant contention of resources
B. implements shared control plane resources
C. implements dedicated chassis resources
D. implements dedicated data plane resources
Answer: D
Q15. Refer to the exhibit.
In the topology, networks in VRF A use the service provider network for transport. PE1 and PE2 run MP-BGP VPNv4 peering. Links between PE and P routers have MPLS enabled. Links between R1 and P routers do not support MPLS.
Which technology can be implemented to build MPLS services between P1 and P2?
A. Layer 3 VPN over GRE Tunnels
B. L2TPv3
C. RSVP Signaled Tunneling
D. MPLS LDP Tunnels
E. MPLS TE
Answer: B
Q16. 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
Q17. 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.
Which CLI command on the exhibit causes this behavior?
A. lacp port-priority 32768 in interface configuration mode
B. channel-group 5 mode passive
C. lacp port-priority 32768 in global configuration mode
D. port-channel load-balance dst-mac
Answer: D
Q18. DRAG DROP
Drag and drop the MPLS operation listed on the left to the correct order of the operation on the right.
Answer:
Q19. Refer to the exhibit. How will the redistributed routes on R1 from EIGRP into OSPF be installed in the R4 routing table?
A. as a default route with an E2 route type
B. as a default route with an IA route type
C. as specific routes with an E2 route type
D. as specific routes with an N2 route type
E. as a default route with an N2 route type
Answer: B

Q20. Which are the two fundamental ways in which IEEE 1588 differs from SyncE? (Choose two.)
A. In addition to frequency synchronization, it achieves ToD synchronization to achieve phase alignment which is required for multi-channel communication.
B. It is a purely-based solution, with the actual clock values being passed inside the payloads of special packets dedicated to that task.
C. It offers two major changes over traditional Ethernet to make it suitable for clock distribution: a mandated clock accuracy and the ESMC protocol for clock selection, distribution, management, traceability, and failover.
D. SyncE is a Cisco proprietary ToD technology where IEEE 1588 is a industry standard recommended for interoperability across vendor devices.
E. IEEE 1588 applies to voice-only systems or with low-bandwidth data traffic.
