1Z0-1124-25 Exam Guide: OCI Networking Professional Preparation Plan
The 1Z0-1124-25 exam validates professional-level knowledge of Oracle Cloud Infrastructure networking, including connectivity design, network security, hybrid and multicloud architecture, migration, and troubleshooting. It is aimed at network engineers, administrators, infrastructure specialists, system administrators, and IT operations professionals who manage cloud networking. This guide helps you decide whether the official OCI Networking Professional learning path matches your background, how to use its lab work effectively, and when to schedule your exam attempt.
What does 1Z0-1124-25 validate?
1Z0-1124-25 is associated with the Oracle Cloud Infrastructure 2025 Networking Professional credential. Oracle’s Japanese announcement identifies the corresponding Japanese exam as 1Z0-1124-25-JPN and links it to the Oracle Cloud Infrastructure 2025 Certified Networking Professional certification.
The certification is intended to demonstrate practical OCI networking capability rather than familiarity with isolated product names. Oracle’s official learning path covers planning and designing OCI networking and connectivity solutions, while the related course provides hands-on experience with OCI Networking services for connectivity, network security, and cloud-infrastructure performance.
A useful preparation target is therefore not simply to memorize service definitions. You should be able to interpret a network requirement, select an appropriate OCI design, identify security or routing implications, and troubleshoot a configuration that does not behave as intended.
Who should take this exam?
This exam is most relevant to professionals who design, administer, secure, or troubleshoot OCI network configurations. Oracle specifically describes the associated course as intended for network engineers, administrators, infrastructure specialists, system administrators, and IT operations professionals managing cloud infrastructure and network configurations.
Candidates with practical networking experience should connect OCI terminology to concepts they already know, such as routing, segmentation, DNS, private connectivity, firewalls, and hybrid links. Candidates who are strong in general cloud concepts but have limited networking experience should spend additional time building those foundations before attempting advanced OCI designs.
Oracle recommends its OCI Architect Associate course as a prerequisite for the OCI Networking Professional course. This is an official training recommendation, not evidence that a separate certification or formal prerequisite is mandatory for the exam. Check Oracle’s current certification catalog for the applicable registration requirements before purchasing an attempt.
A sensible readiness check
Before booking, confirm that you can explain how traffic should move between OCI resources, on-premises networks, and external environments; how access is restricted; and how you would isolate the cause of failed connectivity. If those tasks require repeated reference to basic OCI architecture concepts, complete the recommended Architect Associate preparation first.
Which skills belong in your study plan?
The official learning path provides the clearest scope available in the supplied research. It includes hybrid and multicloud network architecture design, secure OCI networking operations, workload migration, and troubleshooting, in addition to planning and designing OCI networking and connectivity solutions.
The 2025 release also adds specific coverage of Zero Trust Packet Routing, IPSec over FastConnect, DNSSEC, OCI Network Firewall tunnel inspection, and Object Storage private endpoints. These topics deserve deliberate review because they represent changes Oracle called out for the 2025 networking release.
No official domain percentages or exam blueprint weights are provided in the supplied sources. Do not assign study time from an unofficial percentage table, and do not compare unlabeled percentages. Instead, use the learning path topics as study domains and prioritize areas where your hands-on decision-making is weakest.
Design and connectivity
Practice translating requirements into a topology. Consider trust boundaries, address planning, route propagation, private versus public access, and the relationship between OCI resources and external networks. Your notes should explain why a design satisfies the requirement, not only which service appears in the diagram.
Security operations
Review how network security controls affect permitted traffic and how layered controls interact. Include the 2025 topics Oracle identifies: Zero Trust Packet Routing, DNSSEC, OCI Network Firewall tunnel inspection, and Object Storage private endpoints. Treat these as design and troubleshooting subjects rather than vocabulary lists.
Hybrid, multicloud, and migration
Study the decisions involved when OCI connects to an existing data center or another cloud. Include IPSec over FastConnect in the 2025 update review, and trace how migration changes routing, name resolution, access paths, and security controls.
Troubleshooting
Build a repeatable diagnostic sequence. Start with the intended path, then check addressing, route selection, security controls, name resolution, and service-specific access conditions. Keep a record of symptoms, likely causes, tests, and corrective actions so that troubleshooting becomes a process rather than guesswork.
What is the exam format?
Oracle states that the OCI 2025 Networking Professional exam uses a multiple-choice format and consists of 50 multiple-choice questions. Oracle also states that the passing score is 68%. The supplied official sources do not establish the exam duration, delivery channel, language availability for the base exam, or the exact scoring treatment of individual questions.
Use the format information to shape your preparation, but do not treat the passing score as a target for minimal memorization. A candidate who can reason through unfamiliar network scenarios is better positioned than one who has only learned isolated answer patterns. Confirm the current exam record and scheduling choices in Oracle MyLearn before committing to an appointment.
How to use the passing score responsibly
The official passing score is 68%, but it does not tell you which questions will appear or how difficult a particular attempt will feel. Set a personal readiness threshold above the published minimum on legitimate practice exercises, and require yourself to explain each answer. Avoid calculating a supposed safe number of correct answers from the passing percentage because Oracle’s supplied information does not describe its scoring method.
What the official sources do not confirm
The research does not provide a duration, exam price, number of answer choices, delivery method, testing-center policy, remote-proctoring policy, or complete objective list. Do not rely on third-party pages that fill those gaps with old or unverified details. Use Oracle’s certification catalog and the exam scheduling workflow for current transaction and delivery information.
How should you sequence your preparation?
Start with architecture and connectivity fundamentals, move into security and 2025-specific features, then finish with integrated troubleshooting. This sequence mirrors the way network decisions depend on earlier choices: an unclear topology makes route analysis difficult, and an unclear route makes security diagnosis unreliable.
A strong study cycle has four passes. First, learn the purpose and boundaries of each service or feature. Second, draw or build a design. Third, test expected and unexpected traffic paths. Fourth, explain the design and diagnosis without looking at notes. Repeat the cycle for topics that remain uncertain.
Do not begin with random practice questions or exam dumps. They can encourage recognition of wording without building the ability to design or troubleshoot OCI networks, and leaked or unauthorized material is not a reliable preparation method. Use Oracle’s learning path, course material, labs, and current certification information instead.
Pass one: establish the architecture
If OCI architecture is unfamiliar, complete the recommended Architect Associate preparation or review equivalent knowledge. Create a one-page reference that shows compartments, virtual networks, subnets, routing decisions, security boundaries, DNS dependencies, and connections to external environments. The purpose is to make relationships visible.
Pass two: study by decision
For each topic, write a requirement followed by a design choice and a reason. For example, describe a private service-access requirement, identify the relevant access pattern, and state what traffic should not be exposed. Use the same format for hybrid connectivity, firewall inspection, DNS integrity, and migration.
Pass three: use the lab deliberately
Do not spend lab time watching demonstrations passively. Enter with a short task list: build or inspect a topology, validate expected traffic, introduce one controlled misconfiguration, and document the diagnostic evidence. Reset or clean up only after you understand what changed and why.
Pass four: explain without notes
At the end of a study session, explain a design aloud or in writing as if handing it to an operations colleague. Include assumptions, traffic direction, security controls, failure symptoms, and the next diagnostic test. If you can name a service but cannot explain its place in the traffic path, return to the design exercise.
How can you get value from the official lab?
The Oracle course includes a scheduled lab environment, and the supplied course instructions require candidates to schedule lab time. Plan the lab before starting the course, test your system, and reserve time for repetition rather than using the environment only once. Oracle’s instructions also state that the environment is unavailable during a stated maintenance window and returns in the same state afterward.
The lab instructions say that credentials should be checked before the scheduled lab and that username and password details are provided through the Cloud Host Name Details section. They also describe system testing through ouconnect.oracle.com and provide Oracle support instructions for lab issues. Follow the current course page rather than copying credentials or operational steps into public notes.
Oracle states that the lab can be extended for another 6 days. Treat that as a supported extension option, not as a substitute for planning. Availability, scheduling, and extension controls may depend on the course interface and current conditions.
A practical lab checklist
Schedule the lab before you need it. Test the supported browser, connection, audio, and access path shown on the course page. On the first session, verify that you can reach the assigned environment and locate the student material. During each session, save a short topology sketch and a change log outside the lab so your learning survives the environment period.
Lab mistakes that waste time
Avoid changing several controls at once, skipping the initial working state, or treating a successful deployment as proof that you understand the traffic path. Do not publish lab credentials or place them in community questions. If the environment fails, use the course support process instead of repeatedly modifying the configuration without evidence.
What should a four-stage roadmap look like?
A flexible roadmap is more useful than a fixed promise of readiness. Use stage one to measure prerequisites, stage two to complete the official learning content, stage three to reinforce the 2025 networking additions and lab scenarios, and stage four to review weak areas and verify current scheduling information.
The official learning path is listed as providing more than 17 hours of expert training, and its course is shown as 17 hours and 11 minutes. That is the scope of the listed training, not a guaranteed total preparation time. Your required study time will vary with prior OCI and networking experience.
Stage one: baseline and scope
Review the official exam and learning-path records. Identify whether your gaps are in OCI architecture, enterprise networking, security, or troubleshooting. Read the recommended Architect Associate prerequisite information, then make a topic inventory covering design, operations, hybrid and multicloud connectivity, migration, and troubleshooting.
Stage two: complete the learning path actively
Work through the official content while building your own diagrams and decision notes. After each topic, answer three questions: what requirement does this solve, what traffic or trust boundary does it affect, and what evidence would show that it is working? Mark any answer that depends on an assumption for lab verification.
Stage three: target the 2025 additions
Create focused exercises for Zero Trust Packet Routing, IPSec over FastConnect, DNSSEC, OCI Network Firewall tunnel inspection, and Object Storage private endpoints. For each, describe the intended use, the relevant security or connectivity implication, and one plausible failure symptom. Keep the exercises conceptual or use the authorized Oracle lab; do not seek live exam questions.
Stage four: readiness review
Review only the areas where your explanations remain weak. Use mixed scenario practice to force transitions between architecture, security, migration, and troubleshooting. Before scheduling, confirm the current exam listing, language, delivery details, and any applicable policy in Oracle’s official certification workflow.
How should you approach scenario-based multiple-choice questions?
Read the requirement before inspecting the answer choices. Identify the traffic source, destination, required path, trust boundary, and constraint. Then eliminate options that violate the requirement, expose an unnecessary endpoint, omit a required route or control, or solve a different problem.
For troubleshooting questions, separate the observed symptom from the suspected cause. A failed connection may involve routing, security rules, name resolution, an endpoint choice, or an external link. Select the answer that addresses the evidence in the scenario, not the most familiar OCI service name.
When two answers seem plausible, compare their assumptions. Ask which option satisfies the stated requirement with fewer unsupported changes and whether it preserves the intended security posture. Do not infer that an answer is correct merely because it contains a feature introduced in the 2025 release.
A useful note-taking method
For each practice scenario, record requirement, path, control, evidence, and decision. This prevents a common error: jumping from a product keyword directly to an answer without tracing how packets, names, and permissions are expected to behave. Review the notes later and remove explanations that rely on undocumented assumptions.
Which preparation mistakes should you avoid?
The most damaging mistake is studying the exam identifier without studying the networking decisions behind it. Other frequent problems include using obsolete material, ignoring the 2025 additions, treating the lab as optional, and scheduling before verifying the current official record.
Do not use unauthorized dumps, purported leaked questions, or memorization claims as a substitute for training. They may be inaccurate, may omit updated topics, and do not develop transferable troubleshooting skill. They also provide no reliable basis for predicting your result.
Do not invent a blueprint from percentages found on an unverified site. The supplied research contains no official domain weights. Build your plan from Oracle’s stated learning-path scope and the specific 2025 coverage Oracle announced.
A final error audit
Before booking, check that you can distinguish design from operations, explain private access choices, reason about hybrid connectivity, incorporate security controls into the traffic path, and troubleshoot methodically. If your notes are mostly definitions and screenshots, add scenario explanations and controlled lab work.
How do you schedule without relying on stale information?
Oracle’s general certification process says to buy an exam attempt, choose a date, and schedule through Oracle MyLearn; it also states that candidates have six months to take the exam after buying an attempt. Because exam availability, delivery choices, language support, pricing, and policy can change, verify those details in the current Oracle workflow before payment.
The supplied Japanese Oracle notice dated August 6, 2026 says that 2025 Japanese Oracle Cloud certification exams will end on September 30, 2026, while already-earned certifications do not immediately become invalid. The notice is specific to Japanese exams. It should not be treated as confirmation of the status of the base 1Z0-1124-25 exam.
Oracle’s learning-path page states that the OCI Networking Professional 2025 learning path is scheduled to be archived on September 30, 2026. If you plan to use that resource, check its availability and complete any necessary lab or study activity in time. Confirm all time-sensitive details directly with Oracle.
Your next scheduling actions
Open the official Oracle certification catalog and locate the current exam record. Compare the identifier and credential name with your intended language. Review the available appointment and delivery information in Oracle MyLearn, check the attempt validity terms shown at purchase, and save the confirmation details. Do not rely on a third-party listing for a current date or status.
What should you do next?
Use Oracle’s learning path as the central study source, measure your readiness through design and troubleshooting tasks, and schedule only after verifying the live exam record. The immediate next step is to compare your experience against the official audience and recommended prerequisite, then create a gap list covering connectivity, security, hybrid architecture, migration, and troubleshooting.
After that, reserve the lab, study the 2025 additions explicitly, and maintain a concise decision notebook. Review Oracle’s certification page again before purchasing or scheduling so that language, delivery, availability, and policy information comes from the current official source rather than an archived page or third-party summary.
Conclusion
1Z0-1124-25 preparation should result in explainable OCI networking decisions, not a collection of recalled answers. Use the official learning path to structure study, use authorized lab time to test traffic and security assumptions, and treat the 2025 feature additions as required review areas. Before committing to an appointment, confirm the current exam record and scheduling details in Oracle MyLearn, then proceed only when you can design, secure, migrate, and troubleshoot OCI connectivity with a repeatable method.
