Reinforce 1Z0-1085-26 concepts with active-recall study cards covering all 4 blueprint domains. Each card shows the question on the front and the correct answer with a full explanation on the back.
Flashcards work through active recall — the process of retrieving information from memory rather than passively re-reading it. Research consistently shows that active recall produces stronger, longer-lasting memory than re-reading study guides. For 1Z0-1085-26 preparation, this means flashcards are one of the highest-return study tools available.
Attempt recall first
Read the 1Z0-1085-26 question on each card, pause, and attempt to formulate the answer in your own words before revealing. This retrieval attempt — even if wrong — dramatically strengthens memory compared to immediately reading the answer.
Review wrong cards again
When you get a card wrong, note it and add it back to your review pile. Spaced repetition — seeing difficult cards more frequently — is the mechanism that makes flashcard study far more efficient than linear reading.
Study by domain
Group your 1Z0-1085-26 flashcard sessions by domain for the first 3–4 weeks. Master one domain before moving to the next. In the final week, shuffle all cards together to test cross-domain recall — which is what the real 1Z0-1085-26 exam requires.
Short sessions beat marathon reviews
20–30 flashcard cards per session, done daily, produces better retention than a single 200-card marathon session. Five short daily sessions per week over 4 weeks gives you over 400 total card reviews — enough to reliably pass 1Z0-1085-26.
Sample cards from the 1Z0-1085-26 flashcard bank. Read the question, think of the answer, then read the explanation below.
A security officer wants to monitor security risks across multiple OCI tenancies and compartments from a single consolidated dashboard. Which OCI service should they configure?
OCI Cloud Guard
OCI Cloud Guard is a cloud security posture management service that helps customers monitor, assess, identify, and maintain a strong security posture on OCI by detecting misconfigured resources and insecure user activities.
An application administrator is configuring a high-availability database cluster across three Fault Domains in a single Availability Domain. During a scheduled infrastructure maintenance event affecting Fault Domain 1, the administrator notices that one of the database nodes becomes unreachable. What is the expected behavior of OCI Fault Domains in this scenario?
Only instances in Fault Domain 1 are impacted by the maintenance, while instances in Fault Domains 2 and 3 continue to run normally without disruption.
OCI Fault Domains are independent, isolated groups of hardware within a single Availability Domain, each with its own power, cooling, and network. When maintenance affects Fault Domain 1, only resources in that fault domain are impacted; instances in Fault Domains 2 and 3 remain fully operational because they are physically and logically separate. This isolation is the core purpose of fault domains: to prevent a single failure or maintenance event from affecting all resources in an Availability Domain.
An administrator wants to restrict inbound SSH access to a specific group of database compute instances without modifying subnet-level security rules. Which OCI feature should be used to define these fine-grained VNIC rules?
Network Security Groups
Network Security Groups (NSGs) allow you to apply security rules to a specific set of VNICs of your choice, independent of subnets.
Your company has deployed resources across multiple compartments in Oracle Cloud Infrastructure (OCI). You need to track operational costs and allocate cloud spend back to specific business units using metadata key-value pairs attached to resources. Which OCI feature should you use?
Cost-tracking tags
Tags in OCI allow you to attach metadata to resources, which can then be used in Cost Analysis for tracking and allocating spend.
You need to restrict access to a specific compute instance based on the application it is running, without affecting other instances in the same subnet. Which security feature should you use?
Network Security Groups
Network Security Groups (NSG) allow fine-grained security at the VNIC level.
An organization is setting up a hybrid network architecture using OCI FastConnect with a Partner/Provider model. They need to ensure that their on-premises network can communicate with multiple VCNs across different regions using private IP addresses without traversing the public internet. Which OCI component is mandatory to achieve this?
Dynamic Routing Gateway (DRG)
A Dynamic Routing Gateway (DRG) version 2 supports attaching to FastConnect and can peer across regions or connect multiple VCNs to a single on-premises connection.
You are troubleshooting intermittent packet drops between two subnets in different VCNs connected via a Local Peering Gateway (LPG). Both VCNs have non-overlapping CIDR blocks. What is a common misconfiguration that could cause this issue?
Missing route table entries directing traffic to the Local Peering Gateway in both VCNs
VCN route tables must have rules pointing traffic destined for the peer VCN CIDR block to the Local Peering Gateway.
A multinational corporation has strict data residency regulations that prohibit their core financial data from leaving their physical corporate headquarters, yet they want to use OCI managed services and the exact same control plane API. Which OCI deployment model satisfies these requirements?
OCI Dedicated Region
OCI Dedicated Region or OCI Cloud@Customer allows organizations to run OCI services on-premises, maintaining data residency while using the public cloud control plane and APIs.
A developer has deployed a Node.js web application on an OCI Compute instance, but external users cannot access the application on port 3000. The instance's VCN has a security list allowing TCP traffic on port 3000. What additional OS-level configuration is likely blocking the traffic?
The local OS firewall (such as firewalld or iptables) running on the compute instance.
Even when the VCN security list allows TCP port 3000, the instance's local OS firewall (firewalld, iptables, or nftables) can independently block inbound traffic. OCI security lists and NSGs operate at the VCN level, not inside the guest OS, so both layers must permit the traffic. This is the most likely OS-level cause of the connectivity failure.
An administrator creates a new dynamic group with matching rules, but instances belonging to that group are not receiving the permissions granted by the policy referencing the dynamic group. What is the most likely cause?
No IAM policy has been created that grants permissions to the dynamic group.
A dynamic group only defines membership based on matching rules; it grants no permissions by itself. Permissions are granted exclusively through IAM policies that reference the dynamic group as the principal. If no such policy exists, instances in the group receive nothing, which is the most likely cause described.
You have a parent compartment named 'ParentComp' and a child compartment named 'ChildComp'. If you write an IAM policy at the root tenancy level granting a group access to 'ParentComp', what is the inheritance rule regarding 'ChildComp'?
The policy automatically applies to ChildComp because permissions inherit downward in compartment hierarchies.
Policies defined at a parent compartment or tenancy level automatically inherit down to all nested child compartments.
An administrator needs to store infrequently accessed backups in OCI Object Storage that require long-term retention and can tolerate a retrieval time of up to several hours. Which storage tier is most cost-effective?
Archive Storage
Archive Storage is designed for data that is rarely accessed and has a multi-hour retrieval latency, offering the lowest cost.
Which OCI construct serves as the root container for all your cloud resources and acts as the logical boundary for managing users, groups, and compartments?
Tenancy
The Tenancy is the root compartment and overarching container for all OCI resources.
A web application hosted on OCI requires layer-7 load balancing, SSL termination, and cookie-based session persistence across multiple backend compute instances. Which OCI Load Balancer type meets these requirements?
OCI Layer 7 Load Balancer
The OCI Layer 7 Load Balancer provides HTTP/HTTPS traffic management, SSL termination, and session stickiness.
An application developer needs to trigger a data-processing script immediately whenever a new object is uploaded to an OCI Object Storage bucket. Which OCI service should be used to execute the script in a serverless manner?
OCI Functions triggered via OCI Events
OCI Events service captures changes to cloud resources and can automatically trigger OCI Functions in response to Object Storage uploads.
You need to export billing and usage data automatically every day into an Object Storage bucket for custom financial analysis and reporting. Which OCI feature facilitates this?
OCI Usage Reports
Usage Reports in OCI automatically generate detailed CSV cost and usage reports and deposit them into a designated tenancy-owned Object Storage bucket daily.
Your organization is launching a global e-commerce platform. Users will access the platform from North America, Europe, and Asia. To minimize latency for these users, what is the best practice approach for deploying resources on OCI?
Deploy regional instances in multiple OCI regions corresponding to your user geographic distribution and use OCI Traffic Management to route users to the closest region.
To minimize latency for a globally distributed user base, resources must be placed physically close to those users. Deploying regional instances in multiple OCI regions aligned with user geography, combined with OCI Traffic Management steering policies (such as geolocation or latency-based routing), ensures users are served from the nearest healthy region. This is the standard OCI multi-region architecture pattern for global applications.
If an instance in a public subnet cannot reach the internet, what is the first thing you should check?
Route table rules
Route tables must have a rule directing traffic to the Internet Gateway.
You need to allow database instances in a private subnet to communicate with Object Storage over the private network. Which service is required?
Service Gateway
A Service Gateway allows communication between VCN and OCI public services over the OCI private network.
You need to migrate a legacy application to OCI that requires a specific IP address to be retained for compliance. Which OCI networking feature allows you to attach a specific public IP to an instance?
Reserved Public IP
Reserved Public IPs are long-lived public IP addresses that can be assigned to resources and retained after the resource is deleted.
Your application requires a high-performance, POSIX-compliant shared file system that can be accessed by multiple compute instances across different availability domains. Which service should you choose?
File Storage Service
OCI File Storage (FSS) provides a distributed, NFS-based file system accessible from multiple instances.
An enterprise application deployed on OCI is experiencing frequent Layer 7 HTTP flood attacks and SQL injection attempts. Which OCI service provides comprehensive protection against these web vulnerabilities?
OCI Web Application Firewall
OCI Web Application Firewall (WAF) is a cloud-based, PCI-compliant security service that protects applications from malicious internet traffic, including cross-site scripting (XSS), SQL injection, and HTTP floods.

Both flashcards and practice questions are evidence-based study tools. The difference is in what they train:
Flashcards — concept retention
Best for memorising definitions, acronyms, protocol behaviours, command syntax, and conceptual distinctions. Use flashcards to build the foundational vocabulary that 1Z0-1085-26 questions assume you know.
Best in: weeks 1–3
Practice tests — application
Best for applying concepts to realistic scenarios, eliminating distractors, and building exam stamina.1Z0-1085-26 questions test scenario reasoning — not just recall — so practice tests are essential.
Best in: weeks 3–6
The most effective 1Z0-1085-26 study plan combines both: use flashcards for the first 2–3 weeks to build conceptual foundations, then shift to practice tests and mock exams in the final 2–3 weeks to apply and benchmark that knowledge. Most candidates who pass on their first attempt use both tools.
