Q1. MPLS Service Providers use Route Distinguishers and Route Targets as methods to control routing for customer VRFs. Which two statements are true about Route Distinguishers and Route Targets? (Choose two.) 

A. Route Targets are values that are used by a PE router to uniquely identify a VRF within its local MP-BGP VPNv4 table. 

B. Route Distinguishers are used by PE routers by exporting and importing routes into a local VRF. 

C. Route Targets are used by PE routers to define how to import and export prefixes into a local VRF database. 

D. Route Targets are extended communities that are used by MP-BGP to identify routes as they are advertised to neighbor PE routers. 

E. Route Distinguishers are values that are used by a PE router to uniquely identify a VRF within its local MP-BGP VPNv4 table.

Q2. Refer to the exhibit. 

Two ISPs have decided to implement MPLS Inter-AS TE. All routers have full reachability to all subnets. RSVP and MPLS TE have been enabled in all routers interfaces in both ISPs, yet Tunnel 14 is not up Which configuration will fix this issue? 

A. On R1, apply the command: 

interface Tunnel14 

mpls traffic-eng passive-interface nbr-te-id 10.10.10.4 nbr-igp-id ospf 10.10.10.1 

B. On R1, apply the command: 

interface Tunnel14 

mpls traffic-eng passive-interface nbr-te-id 10.10.10.4 nbr-igp-id isis 10.0000.0000.0004.00 

C. On R1. apply the command: 

interface Tunnel 14 

tunnel mpls traffic-eng path-option 1 dynamic 

D. I On R2. apply the command: 

interface Fa0/1 

ip router isis 

! 

router ospf 1 

redistribute isis subnets 

On R3, apply the command: 

interface Fa0/1 

ip ospf 1 area 0 

! 

router isis 

redistribute ospf 1 

E. On R2, apply the command: 

interface Fa0/1 

mpls traffic-eng passive-interface nbr-te-id 10.10.10.3 nbr-igp-id ospf 10.10.10.2 

! 

On R3, apply the command: 

interface Fa0/1 

mpls traffic-eng passive-interface nbr-te-id 10.10.10.2 nbr-igp-id isis 10.0000.0000.0003.00 

F. On R2, apply the command: 

interface Fa0/1 

mpls traffic-eng passive-interface nbr-te-id 10.10.10.3 nbr-igp-id isis 10.0000.0000.0003.00

Q4. 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.

Q6. A network engineer is designing the BGP architecture with a requirement of preventing the AS 65001 from becoming a Transit AS path, using the following configuration: 

router bgp 65000 

neighbor 10.0.0.1 route-map BGP-ROUTE-POLICY in 

The goal is to prevent routes learned from 10.0.0.1 from being advertised to any other eBGP peering in the AS 65000. What command should be used within the route map to achieve this goal while keeping existing route policies in place? 

A. set community no-export additive 

B. set community no-advertise 

C. set community no-advertise additive 

D. set community no-export

Q7. 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

B. Industry standard that guarantee interoperability, since granular details, such as specific field values are specified. 

C. A mandated clock accuracy of 4.6ppm. 

D. The ESMC protocol for clock selection, distribution, management, traceability, and failover. 

E. High-priority synchronization packets so it can continually adjust its own oscillator.
