An engineer is suspecting an issue where there is a mismatch between RIB and FIB. The same prefix is learned via different routing protocols. Based on this output, from which protocol originated the prefix that was installed in the FIB?
Answer(s): D
The key information here is the peer_as field in the output, which shows peer_as: 65100. This indicates that the route was learned from a BGP peer with the Autonomous System (AS) number 65100.BGP uses AS numbers to identify the origin of routes, and the presence of a peer_as field confirms that the route was learned via BGP.
Refer to the exhibit. Two data centers are connected using a VXLAN EVPN Multi-Site fabric. VLAN 10 fails to be extended between the sites. Which configuration resolves the issue?
Answer(s): A
The output indicates that the VXLAN EVPN Multi-Site fabric is experiencing DCI isolation, which means the connection between the data centers is not working as expected. To resolve this, you need to enable DCI (Data Center Interconnect) tracking on the appropriate interface that handles the connection between the data centers.In this topology, interface eth1/18 is the link connecting Leaf3 to R1, which plays a role in the Data Center Interconnect (DCI) between the two sites. By configuring evpn multisite dci-tracking on interface eth1/18, you can resolve the isolation issue and extend VLAN 10 across the sites.
Refer to the exhibit. An engineer is troubleshooting an issue with the Cisco ACI fabric discovery. During the Cisco APIC initialization, the infra VLAN was set to 4, and the TEP pool was configured to use subnet 11.0.0.0/16. Which action resolves the issue?
In a Cisco ACI fabric, the APIC (Application Policy Infrastructure Controller) must be directly connected to one of the leaf switches (e.g., Leaf-101) for proper fabric discovery and management. In the current topology, the APIC is connected to an L2 switch, which prevents it from being properly discovered by the leaf switches.To resolve the issue, you should connect the Cisco APIC directly to Leaf-101 to ensure it can communicate correctly with the ACI fabric and participate in the discovery process.
Refer to the exhibit. An engineer fails to load the Cisco Nexus 9000 Series Switch to configuration mode. Which command set resolves the issue?
The error suggests that the system is in loader mode because it failed to load the correct NX-OS image.To resolve this issue, you need to boot the switch using the correct NX-OS image from the bootflash. The command boot nxos.7.0.3.I7.8.bin will load the correct image.After booting, you should ensure that the correct NX-OS image is set in the boot configuration, using boot bootflash:nxos.7.0.3.I7.8.bin, and save the configuration with copy run start to prevent this from happening again on the next reboot.
Refer to the exhibit. Which action must be taken to change the interface Eth1/3 on N9K-3 from suspended to up in the port channel?
The channel-group ID must be consistent across all switches participating in the same port-channel. In this case, N9K-1 and N9K-2 are using channel-group 2, while N9K-3 is using channel-group 9, which leads to a mismatch and causes the interface Eth1/3 to be suspended in the port-channel.Changing the channel-group ID on N9K-3 from 9 to 2 will ensure consistency across the switches, allowing the interface to come up in the port-channel.
