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 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

Q3. Refer to the exhibit. 

An ISP engineer has been asked to identity a method to protect the PE and to control the number of BGP prefixes learned from his customers. The BGP session should be dropped if the PE router receives more than 1000 BGP prefixes. A syslog message should be generated when the number of BGP prefixes learned from CE exceeds 850. 

Which Cisco IOS command should the engineer apply on PE routers? 

A. neighbor 10.1.1.2 maximum-prefix 1000 85 

B. neighbor 10.1.1.2 maximum-prefix 1000 850 

C. neighbor 10.1.1.2 maximum-prefix 1000 85 warning-only 

D. neighbor 10.1.1.2 maximum-prefix 1000 850 warning-only

Q4. Cisco IOS XR has implemented a nonstop routing feature so that when RP failover occurs, the routing information can be recovered locally. Which protocol does not support the NSR feature? 

A. OSPF 

B. LDP 

C. BGP 

D. IS-IS 

E. RSVP

Q5. Refer to the exhibit. 

ABC and XYZ MPLS VPN customers are accruing Internet access. Both CEs are sending traffic to the Internet. Which statement about their connectivity is true? 

A. Both CEs will have connectivity. 

B. Only CE-XYZ will have connectivity. 

C. Neither CEs will have connectivity, as both CEs are using the same NATed subnet. 

D. Only CE-ABC will have connectivity. 

E. Neither CEs will have connectivity, as IAR does not have route back to the NATed subnet.

Q6. An R1 router requires an equal load balancing to reach the prefix 192.168.0.0/16 over two exit points: through R2 and R3 routers. Which two options must be configured on the R1 router to achieve this goal? (Choose two.) 

A. The BGP maximum path feature must be configured on R1. 

B. The BGP PIC core must be enabled on R1 

C. Weight, local-pref, MED, as-path length, origin, and the BGP next-hop IGP cost must be the same for the R2 and R3 IBGP updates to R1. 

D. The BGP Link Bandwidth feature must be applied on R1. 

E. BGP extended community exchange must be enabled between IBGP neighbors.

Q7. A network engineer needs to connect two core switches that use Gigabit Ethernet interfaces in an MPLS backbone and that are separated by a distance of 60 km. Which Cisco GBIC achieves this goal? 

A. Cisco 1000BASE-T GBIC 

B. Cisco 1000BASE-SX GBIC 

C. Cisco 1000BASE-LX/LH GBIC 

D. Cisco 1000BASE-ZX GBIC

Q8. Refer to the exhibit. In the short-pipe QoS mode, this customer has QoS control for which two links? (Choose two.) 

A. a 

B. c 

C. d 

D. b 

E. e

Q9. 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

Q10. Refer to the exhibit. 

A company has a requirement to provide communication among remote sites via multipoint GRE tunnels. This communication is not working yet. Which is the root cause of this issue? 

A. The key that is used on the DMVPN tunnel between the spoke and hub ends does not match. This causes the tunnel to fail. 

B. BGP IPv4 multicast address-family is missing between hub and spoke points. 

C. The GRE tunnel is not sourced from a physical interface. The DMVPN traffic does not know where to forward packets. 

D. The NHRP network ID does not match in the hub and spoke configuration causing NHRP negotiations to fail and the mGRE to stay down.
