1Z0-1072-26 Networking Practice Question
You have configured a FastConnect dedicated circuit using a Provider model, but your on-premises routers cannot reach OCI VCN instances. BGP status is showing as 'Idle'. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
BGP peering IP addresses or Autonomous System Numbers (ASNs) are misconfigured between the Oracle router and on-premises router.
BGP status 'Idle' typically indicates that the BGP peer IP configuration is incorrect, or there is an issue with the virtual circuit provisioning state, or access control lists/firewalls are blocking TCP port 179.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The route table on the VCN subnet does not have a route to 0.0.0.0/0.
Why it's wrong here
Missing VCN routes affect packet forwarding, not BGP session state establishment (Idle/Connect).
- ✗
The Security List on the DRG attachment blocks ICMP traffic.
Why it's wrong here
ICMP traffic blocking does not prevent BGP state progression.
- ✓
BGP peering IP addresses or Autonomous System Numbers (ASNs) are misconfigured between the Oracle router and on-premises router.
Why this is correct
Mismatched peer IPs, ASNs, or blocked TCP port 179 will keep BGP in an Idle or Active state.
- ✗
The public subnet has an incorrect Internet Gateway route.
Why it's wrong here
FastConnect uses private virtual circuits and does not rely on Internet Gateways.
