OCI Networking Professional study guide
OCI Networking Professional · Work through your exam, one topic at a time.
The Oracle Cloud Infrastructure 2023 Certified Networking Professional credential is aimed at networking engineers, cloud architects, and administrators who design, deploy, and operate OCI network topologies. The exam is delivered as 1Z0-1071-23 and validates advanced, hands-on knowledge rather than introductory cloud concepts. Its published blueprint splits coverage evenly across four domains: networking fundamentals and Virtual Cloud Networks (25%), routing, gateways, and connectivity (25%), load balancing and DNS (25%), and security, monitoring, and troubleshooting (25%). Because a quarter of the content sits in each area, you cannot compensate for a weak domain with strength in another; candidates should expect scenario questions that combine, for example, a route table, a security rule, and a load balancer health check in a single problem. The OCI Networking Professional study guide has 4 sections and about 1,414 words.
01Networking Fundamentals and Virtual Cloud Networks (VCN)
This domain covers VCN design: CIDR planning, regional versus AD-specific subnets, VNIC and IP assignment, and the two security rule models. Expect scenario questions that ask which construct enforces a rule or why traffic is blocked.
369 words, about 2 min02Routing, Gateways, and Connectivity
Questions focus on route selection, gateway choice, and hybrid connectivity: which target serves which traffic, how DRG route tables exchange routes, and when to use VPN versus FastConnect. Each route table rule pairs a destination CIDR with a target.
342 words, about 2 min03Load Balancing and DNS
This domain tests L4/L7 load-balancing design - listeners, backend sets, health checks, policies - and DNS zone, resolver, and traffic-management choices. OCI Load Balancer is regional and flexible: choose a minimum and maximum bandwidth (10 Mbps to 8 Gbps).
343 words, about 2 min04Security, Monitoring, and Troubleshooting
This domain covers defense in depth and operational diagnosis: NSG and security-list behavior, flow logs, metrics and alarms, and tools such as Network Path Analyzer. Both security lists (subnet) and NSGs (VNIC) are stateful: return traffic for an allowed connection is automatically permitted.
