Question 91
Refer to the exhibit.
XR1 and XR2 are sending the prefix 10.11.11.0/24 to XR3. A configured policy on XR1 is incorrectly prepending AS path 11 11 12 12 onto this prefix. A network operator wants to add a policy onto XR3 that will not allow the falsely prepending prefix from being installed. Which policy configuration applied to the XR3 neighbor configuration for XR1 can accomplish this requirement without impact to other or future received routes?

Question 92
Refer to the exhibit
Which router does R1 install as an alternate next hop when trying to reach R3 if LFA is enabled?
Question 93
Refer to the exhibit.
CE1 and CE2 cannot communicate through the service provider BGP peering is established between PE1 and PE2. IS-IS is the only routing protocol running in the service provider core.
What
step can be done to troubleshoot the issue?
Question 94

Question 95
Refer to the exhibit.
CE1 is the gateway router into the provider network via PE1. A network operator must inject a default route into OSPF area 0. All devices inside area 0 must be able to reach PE1. Which configuration achieves this goal?
