Q121. An engineer must implement E-Line services for a service provider network. Which two services apply in this situation? (Choose two.)
Q122. Refer to the exhibit.
R1 is using the RP that is learned via BSR R1 also has a static RP configuration in place.
In order to prefer the static RP over BSR, which configuration should be applied on R1?
A. ip pim bsr-candidate loopback 0 priority 200
B. ip pim rp-address 22.214.171.124 priority 200
C. ip pim bsr-candidate loopback 0 override
D. ip pim rp-address 126.96.36.199 override
Q123. An engineer wants to configure Fast Reroute in the network. Which methodology eliminates RSVP configuration in the network?
A. Enable LDP Fast Synch.
B. Enable IP Fast Reroute.
C. Enable the auto tunnel primary feature.
D. Enable Cisco MPLS TE Fast Reroute.
E. Enable the auto tunnel backup feature.
Q124. An engineer is troubleshooting L3VPN traffic loss over the MPLS-enabled core network when new core links were enabled. Assuming that the IGP is properly configured, which issue causes a temporary data flow blackholing when the IGP and LDP reconvenes?
A. LDP is a Layer 2 protocol forwarding label packets before the IGP reconvened.
B. IP packets are forwarded as soon as routes are learned over a new IGP adjacency before the label exchange happens over the new links
C. MP-BGP sessions between PE and RR routers require extra time to reconverge than the underlying IGP.
D. MPLS-TE tunnels without LDP adjacencies are used over the new links black-holing the traffic before the LDP label exchange is completed
Update 400-201 actual test:
Q125. A network engineer is responsible for implementing a solution with Cisco IOS XR Software that insures continuous forwarding during a control plane failure. Which two technologies should the engineer consider? (Choose two.)
A. TE FRR
B. IP FRR
C. graceful restart
Q126. Which two flexible service mapping features that are used on the ES40 line card can classify traffic into different service instances, in order to consume fewer VLANs? (Choose two.)
C. IP precedence
D. MPLS experimental bit

Q127. A network administrator wants to implement an IP dampening feature for a network. Which parameter identifies how fast the accumulated penalty can decay exponentially?
A. reuse threshold
B. suppress threshold
C. half-life period
D. maximum suppress time
Q128. Refer to the exhibit.
Which piece of information can be derived from this Cisco IOS XR route policy?
A. If the destination is 227.0 0 3 or 227 0 0 13 the default table will be used for reverse path forwarding
B. If the destination ranges between 227.0 0.3 and 227 0.0.13. the IPv4 unicast table will be used for reverse path forwarding
C. If the destination is 188.8.131.52 or 227.0 0.13, the IPv4 unicast table will be used for reverse path forwarding
D. If the destination ranges between 184.108.40.206 and 220.127.116.11. the multicast default table will be used for reverse path forwarding
Q129. DRAG DROP
Drag and drop the IPFIX terminology on the left to the correct description on the right. Not all options will be used.
