   A VCF administrator is troubleshooting an NSX Edge node that is experiencing high CPU usage on the gateway service. The administrator checks the NSX-T metrics and sees that the 'cpu_usage' counter is at 100% for the gateway service. The Edge node has 4 vCPUs and 8 GB of memory. The gateway is a Tier-1 gateway with multiple logical switches connected. What is the most likely cause of the high CPU usage?

   • AThe gateway's firewall rules are misconfigured, causing the gateway to drop all traffic.
   • BThe Edge node's physical NIC is faulty, causing the gateway to retransmit packets.
   • CThe gateway's BGP session is flapping, causing route recalculation.
   • DThe gateway is undersized for the amount of traffic it is handling.

   A VCF administrator is troubleshooting a BGP session between a Tier-0 gateway and an external router. The BGP session is down, and the administrator sees 'Connect' state in the BGP neighbor table. The administrator has verified that the IP addresses and AS numbers are correct. What should the administrator check next?

   • AThe MTU settings on the Tier-0 gateway's uplink.
   • BThe BGP hold timer settings on the Tier-0 gateway.
   • CThe route redistribution settings on the Tier-0 gateway.
   • DThe firewall rules on the Tier-0 gateway that might be blocking BGP traffic (TCP port 179).
