Three full-length practice tests for the Oracle Cloud Infrastructure Networking Professional (1Z0-1124-26) certification exam - 50 questions per test, 90 minutes, 68% to pass, unlimited retakes.
Every question is grounded in Oracle's official exam objectives and product documentation - written fresh for this course, not recycled from public dumps.
What you'll be tested on
- VCN design: subnets, route tables, gateways, and security lists
- Hybrid connectivity: FastConnect, Site-to-Site VPN, and DRGs
- Load balancing: Load Balancer, Network Load Balancer, and traffic management
- Advanced networking: transit routing, hub-and-spoke, and multi-VCN topologies
- Network troubleshooting, monitoring, and Network Visualizer
Where candidates lose points
Transitive routing is the domain that trips up the most candidates: hub-and-spoke topologies built on a DRG, local peering gateways, and multiple route tables require holding several routing states in your head at once, and it's easy to route traffic somewhere it shouldn't reach (or block traffic that should flow). FastConnect versus Site-to-Site VPN tradeoffs and BGP fundamentals are the other weak spot, especially for candidates who've only clicked through the console and never designed a hybrid connectivity architecture from a blank page.
Sample question
A company runs a hub VCN with a DRG attached, and two spoke VCNs peered to the hub through local peering gateways. Traffic from Spoke VCN A must be able to reach Spoke VCN B, but must NOT be able to reach the on-premises network over the DRG's Site-to-Site VPN attachment. Which routing configuration achieves this?
- A. Add a single DRG route table shared by both spoke VCN attachments, with a route rule pointing 0.0.0.0/0 to the VPN attachment
- B. Configure Spoke VCN A's route table to send traffic for Spoke VCN B's CIDR to the LPG, and give the DRG a route table for that attachment that excludes the VPN attachment as a route target
- C. Remove the DRG attachment from Spoke VCN A entirely and rely only on the LPG for all outbound traffic
- D. Attach a Dynamic Routing Gateway directly to each spoke VCN's local peering gateway to isolate routing domains
Full explanations and 149 more questions like this are in the practice tests.
How long to prepare
If you already manage VCNs, FastConnect, or Site-to-Site VPN hands-on, 2-4 weeks of focused review is a reasonable target given the 68% pass mark. Without prior hybrid-connectivity experience, budget more time to actually build a hub-and-spoke topology yourself rather than just reading about one.
