20+ practice questions focused on Networking — one of the most tested topics on the Oracle Cloud Infrastructure 2026 Architect Associate (1Z0-1072-26) (1Z0-1072-26) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Networking PracticeWhich OCI networking component is automatically created when you provision a Virtual Cloud Network using the VCN Wizard with 'Internet Connectivity'?
Explanation: The VCN Wizard's 'Internet Connectivity' option automatically creates an Internet Gateway (IGW) and attaches it to the VCN, enabling outbound internet access for resources in public subnets. The IGW is a highly available, horizontally scaled, redundant component that provides NAT for instances with public IPs. It is the only component among the options that is directly associated with basic internet connectivity in a VCN.
You are configuring an OCI Load Balancer and need to ensure that client source IP addresses are preserved when traffic reaches the backend web servers. Which feature should you enable?
Explanation: To ensure that backend web servers see the original client IP address rather than the load balancer's IP, you must enable the 'Preserve client IP' option in the OCI Load Balancer backend set configuration. By default, the load balancer acts as a reverse proxy and masks the source IP.
You are managing an OCI VCN with CIDR block 10.0.0.0/16. You want to create a subnet that can hold up to 500 usable IP addresses. Which subnet CIDR block should you choose?
Explanation: A /23 CIDR block provides 512 total IP addresses. In OCI, 2 IP addresses are reserved by Oracle (network address and broadcast-equivalent), and 3 are reserved for internal DHCP/router operations, leaving 507 usable IP addresses, which satisfies the requirement for 500.
An OCI architect needs to configure route tables for a VCN where traffic destined for 10.0.1.50/32 must be sent to a specific firewall virtual appliance VNIC (`ip-10-0-1-10`), while all other traffic goes to an Internet Gateway. How should the route table be configured?
Explanation: OCI route tables support both specific CIDR destinations (including /32 host routes) and a default route. To send traffic for 10.0.1.50/32 to the firewall appliance while sending everything else to the Internet Gateway, you add a route rule with destination 10.0.1.50/32 targeting the firewall VNIC's private IP, plus a 0.0.0.0/0 rule targeting the Internet Gateway. OCI uses longest-prefix match, so the /32 wins for that specific host.
An OCI Load Balancer has been configured with SSL termination. The backend servers require incoming traffic to also be encrypted using HTTPS. Which backend set protocol should you choose?
Explanation: If backend servers require encryption, you should configure the backend set to use SSL (HTTPS or TCP with SSL) so the load balancer encrypts traffic before forwarding it to the backend instances.

Practice all Networking questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Networking. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Networking questions on the 1Z0-1072-26 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Networking is tested as part of the Oracle Cloud Infrastructure 2026 Architect Associate (1Z0-1072-26) (1Z0-1072-26) blueprint. Practicing with targeted Networking questions ensures you can handle any format or difficulty that appears.
Yes. Courseiva provides free 1Z0-1072-26 practice questions across all exam topics and domains. The platform includes topic-based practice, mock exams, missed-question review, bookmarked questions, and readiness tracking — no account required.
Difficulty is subjective, but Networking is a high-priority exam concept tested in multiple ways — direct recall, scenario analysis, and command-output interpretation. Consistent practice is the best way to build confidence.
