What can be inferred from the BGP FlowSpec configuration deployed on the internal IT network?

Single Choice

Refer to the exhibit. A network operator recently configured BGP FlowSpec for the internal IT network. What will be inferred from the configuration deployed on the network?

The policy is configured locally on CSR1 and drops all traffic for TCP ports 80 and 443

The policy is configured locally on CSR1 and currently has no active traffic

The policy is learned via BGP FlowSpec and drops all traffic for TCP ports 80 and 443

The policy is learned via BGP FlowSpec and has active traffic

Which routes need to be advertised to 10.10.10.1 in the given BGP configuration?

Single Choice

Refer to the exhibit. An engineer is reviewing the BGP configuration. Which routes must be advertised to 10.10.10.1?

Local routes are permitted, and routes from other ASNs are denied.

All routes whether local or from other ASNs are denied.

Local routes are denied, and routes from other ASNs are permitted.

All routes whether local or from other ASNs are permitted.

Which show command displays per-interface statistics for uRPF drops and suppressed drops?

Single Choice

Refer to the exhibit. Which show command should be implemented to display per-interface statistics about uRPF drops and suppressed drops?

show cef interface

show ip traffic

show ip interface

show ip interface brief

Which statement is true based on the periodic log message generated by R1 and R2 in a network with enabled IS-IS routing?

Single Choice

Refer to the exhibits. R1 and R2 are directly connected and IS-IS routing has been enabled between R1 and R2. R1 generates the above log message periodically.

Based on this output, which statement is true?

IS-IS neighbor authentication is failing for Level 2 PDUs only.

IS-IS neighbor authentication is failing for Level 2 first and then for Level 1 PDUs.

IS-IS neighbor authentication is failing for Level 1 and Level 2 PDUs.

IS-IS neighbor authentication is failing for Level 1 PDUs only.

Architecture Routing Technologies

What configurations are required to meet the given network requirements?

Multiple Choice

Refer to the exhibit. An engineer is updating this network to meet these conditions:
• Area 10 will receive inter-area routes and support mutual redistribution of external routes with the extranet.
• The ::/0 route is prohibited in Area 10.
• Area 11 will receive only the ::/0 route from the ABR.
• External route redistribution is not supported in Area 11.
• The ABR in Area 11 will advertise no interarea routes.

Which two configurations must be performed to meet the requirements? (Choose two.)

Configure area 10 as nssa on R9 and XR32

Configure area 11 as stub no-summary on R7 and as stub on XR31

Configure area 11 as nssa no-summary on R7 and as nssa on XR31

Configure area 11 as nssa default-information-originate on R7 and as nssa on XR31

Configure area 10 as stub on R9 and XR32

Architecture Routing Technologies

Which router in the exhibit has LDP session protection enabled but session hold up is not active?

Single Choice

Refer to the exhibit. With which router does IOSXRV-1 have LDP session protection capability enabled but session hold up is not active?

192.168.0.4

192.168.0.5

192.168.0.1

192.168.0.3

Architecture Routing Technologies

What conclusion can be drawn about the neighbor relationship between routers R1 and R2?

Single Choice

Refer to the exhibit. Assume all other configurations are correct and the network is otherwise operating normally.

Which conclusion can you draw about the neighbor relationship between routers R1 and R2?

The neighbor relationship is up.

The neighbor relationship will be up only if the two devices have activated the correct neighbor relationships under the IPv4 address family.

The neighbor is down because the local-as value for R2 is missing in the R1 neighbor statement.

The neighbor relationship is down because R1 believes R2 is in AS 65012.

Architecture Routing Technologies

What configuration error is preventing the ASBR from establishing a BGP neighborship with a directly connected BGP speaker?

Single Choice

Refer to the exhibit. An engineer is trying to implement BGP configuration on a router. Which configuration error prevents the ASBR from establishing a BGP neighborship to a directly connected BGP speaker?

The routing policy is absent for this Cisco IOS XR eBGP instance.

The TCP session parameters are not specified.

The VPNv4 address family interferes with the BGP IPv4 address family negotiations.

The IPv4 address family configuration under neighbor configuration-mode must be removed.

Architecture Routing Technologies

Which IPv4 multicast address space does router RA use based on the given configuration?

Single Choice

Refer to the exhibit. If router RA is configured as shown, which IPv4 multicast address space does it use?

224.0.0.0/8

225.0.0.0/8

232.0.0.0/8

239.0.0.0/8

Routing Technologies Services

What is the impact of the multicast implementation on the client's network?

Single Choice

Refer to the exhibit. An engineer configured multicast routing on client s network. What is the effect of this multicast implementation?

R2 is unable to share information because the ip pim autorp listener command is missing

R1 floods information about R2 throughout the multicast domain

R2 floods information about R1 throughout the multicast domain

R2 is elected as the RP for this domain
