Refer to the exhibit. An engineer ran this show telemetry command to view subscription SUB11 on RouterX. The engineer then decided that RouterY should provide the same output for sensor group SGroup13 as RouterX. The engineer cannot access RouterX to copy its configuration No access lists on the router block user access.
Which configuration must the engineer apply on RouterY to provide the same output from the show telemetry command?
- A . RouterY(config)# telemetry model-driven
RouterY(config-model-driven)# subscription SGroup13
RouterY(config-model-driven-subs)# sensor-group-id SGroup13 sample-interval 20000 - B . RouterY(config)# telemetry model-driven
RouterY(config-model-driven)# sensor-group SGroup13 RouterY(config-model-driven-snsr-grp)# sensor-path opencong-interfaces:interfaces/interface
- C . RouterY(config)# telemetry model-driven
RouterY(config-model-driven)# destination-group SUB11
RouterY(config-model-driven-dest)# address family ipv4 172.16.10.1 port 22471
RouterY(config-model-driven-dest-addr)# encoding self-describing-gpb
RouterY(config-model-driven-dest-addr)# protocol tcp - D . RouterY(config)# telemetry model-driven
RouterY(config-model-driven)# subscription SUB11
RouterY(config-model-driven-subs)# sensor-group-id SGroup13 sample-interval 20000
RouterY(config-model-driven-subs)# destination-id DGroup1
While an engineer deploys a new Cisco device to redistribute routes from OSPF to BGP, they notice that not all OSPF routes are getting advertised into BGP.
Which action must the engineer perform so that the device allows O, OIA, OE1, and OE2 OSPF routes into other protocols?
- A . Con gure the device to pass only O and E2 routes through it.
- B . Con gure the synchronization keyword in the global BGP configuration.
- C . Con gure the keyword nssa in the redistribution entry.
- D . Con gure the keywords internal and external in the redistribution entry.
Refer to the exhibit.
Router 1 was experiencing a DDoS attack that was traced to interface gigabitethernet0/1.
Which statement about this configuration is true?
- A . Router 1 accepts all traffic that ingresses and egresses interface gigabitethernet0/1.
- B . Router 1 drops all traffic that ingresses interface gigabitethernet0/1 that has a FIB entry that exits a different interface.
- C . Router 1 accepts source addresses that have a match in the FIB that indicates it is reachable through a real interface.
- D . Router 1 accepts source addresses on interface gigabitethernet0/1 that are private addresses.
Refer to the exhibit.
Which additional configuration must an engineer apply to the edge router to inject a default route into the MP-BGP address family for the
Internet_Shared_Service dedicated VRF?
- A .
- B .
- C .
- D .
Refer to the exhibit. An engineer is implementing Auto-RP and reviewing the configuration of the PE-A.
Which configuration permits Auto-RP messages to be forwarded over this interface?
- A . PE-A(config-if)#no ip pim bsr-border
- B . PE-A(config-if)#ip igmp version 3
- C . PE-A(config-if)#ip pim sparse-mode
- D . PE-A(config-if)#ip pim sparse-dense-mode
Refer to the exhibit. An engineer is implementing Auto-RP and reviewing the configuration of the PE-A.
Which configuration permits Auto-RP messages to be forwarded over this interface?
- A . PE-A(config-if)#no ip pim bsr-border
- B . PE-A(config-if)#ip igmp version 3
- C . PE-A(config-if)#ip pim sparse-mode
- D . PE-A(config-if)#ip pim sparse-dense-mode
What is the function of the FEC
eld within the OTN signal structure?
- A . It allows the sending devices to apply QoS within the OTN forwarding structure.
- B . It allows deep inspection of data payload elds.
- C . It allows receivers to correct errors upon data arrival
- D . It allows source nodes to discard payload errors before transmitting data on the network.
ASN 65001 is peering with ASN 65002 to exchange IPv6 BGP routes. All routes that originate in ASN 65001 have a standard community value of 65001:100, and
ASN 65002 is allowed to advertise only 2001:db8:aaaa::/48. An engineer needs to update the ASN 65001 route- ltering configuration to meet these conditions:
✑ Looped routes into ASN 65001 and routes that have traversed 10 or more ASNs must be denied.
✑ Routes accepted into ASN 65001 must be assigned a community value of 65001:200.
Which configuration must be engineer apply to the ASN 65001 border router?
- A .
- B .
- C .
- D .
Refer to the exhibit. A network engineer observed congestion between routers R1 and R4, which are connected on a point-to-point link. Two servers that reside on networks on R1 and R4 generate heavy traffic between them with most traffic going from R4 to R1. To improve overall performance, the engineer wants to drop inbound packets that exceed a configured threshold, without disrupting traffic that passes from R4 to R3.
Which action must the engineer take to resolve the issue?
- A . Implement traffic policing to drop packets that exceed the given threshold.
- B . Implement FIFO to queue excess traffic for transmission when bandwidth is available.
- C . Implement traffic shaping to drop excess packets.
- D . Implement a service policy in the outbound direction on each interface on the link to tag traffic exiting each router.
