1Z0-1085-26 Exam Questions and Answers

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?

You are deploying a mission-critical web application that must remain available even if an entire Oracle Cloud Infrastructure availability domain experiences a major outage. The application architecture requires two compute instances. How should you provision these instances to achieve high availability?

Your development team needs to test an application's resilience against infrastructure hardware failures within a specific OCI region that contains only a single Availability Domain. Which OCI feature should you utilize to distribute your compute instances for fault tolerance?

A multinational corporation requires low-latency access for users in Frankfurt and London, with strict data isolation ensuring European data does not leave designated jurisdictions. Which OCI architectural construct should you use to organize their resources?

An organization is planning a disaster recovery strategy for a Tier-1 financial application. They need a Recovery Point Objective (RPO) of near-zero and a Recovery Time Objective (RTO) of seconds. Which OCI deployment pattern best fulfills these stringent requirements?

You are designing a web application hosted in OCI. You want to ensure that if a top-of-rack switch fails inside a data center, your application remains online. How are OCI Fault Domains engineered to address this specific risk?

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?

A company needs to store petabytes of data that is rarely accessed but must be retained for compliance for 7 years. Retrievals can take up to several hours. Which storage tier should they use?

A cloud architect needs to deploy a cloud-native application using Docker containers without managing any underlying infrastructure, servers, or Kubernetes worker nodes. Which OCI service should they select?

An application running on OCI Compute instances requires shared file storage that can be mounted concurrently across hundreds of Linux instances via the standard NFS protocol. Which OCI storage service is best suited?

Your development team needs to deploy microservices orchestrated via Kubernetes with automated worker node scaling and managed control plane upgrades. Which OCI service should you provision?

You are configuring an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and need to ensure that compute instances in a private subnet can initiate outbound internet connections to download software patches without allowing unsolicited inbound traffic from the internet. Which gateway must you attach to the VCN?

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?

You need to write an IAM policy that allows a group named 'NetworkAdmins' to manage all VCN components, but you want to ensure that this policy is only applicable when evaluated from the home region of the tenancy. How can you accomplish this using policy conditions?

An auditor needs to verify who deleted a critical production virtual cloud network (VCN) yesterday. Which OCI service should the auditor query to find this exact API event history?

Your organization wants to receive an email alert whenever monthly cloud spending reaches 80% of a specified $5,000 threshold. Which OCI tool should you configure?

Which OCI service provides security diagnostic and compliance evaluation tools by continuously monitoring resources against security best practices and industry benchmarks?

An administrator needs to grant a group of database administrators the ability to manage Autonomous Databases only within a specific compartment named DevCompartment, without giving them access to any other resources in that compartment. Which IAM policy statement achieves this requirement?

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?

According to the OCI shared-responsibility model, who is responsible for managing user accounts, password policies, and multi-factor authentication (MFA) configurations?

Your organization has strict compliance requirements and needs to ensure that no compute instance in a specific production compartment can ever have a public IP address attached. Which OCI service should you use to enforce this rule automatically?

An administrator needs to understand where the boundary of customer responsibility lies when deploying compute instances in Oracle Cloud Infrastructure. According to the OCI shared-responsibility model, which responsibility falls solely on the customer?

A developer needs to store database connection strings and API tokens securely so that applications can retrieve them dynamically without hardcoding credentials. Which OCI service is designed specifically for this purpose?

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?
