When creating an OCI Function application, you must select one or more subnets. What type of subnets should you choose if your function needs to call external public APIs over the internet?

A.Subnets with a Service Gateway only

B.Subnets configured strictly as local peering endpoints

C.Subnets with no route table entries

D.Subnets associated with a NAT Gateway or Internet Gateway route table

AnswerD

Outbound internet traffic from private subnets requires a NAT Gateway, while public subnets use an Internet Gateway.

Why this answer

If functions need outbound internet access (e.g., calling public APIs), the associated subnets must have a route table pointing to a NAT Gateway or Internet Gateway.

You want to deploy a Windows compute instance in OCI using your own custom software pre-installed. What is the recommended workflow to achieve this?

A.Upload your local virtual machine disk (VMDK/VHD) directly to a compute instance as a running process.

B.Launch an instance from a standard Windows image, install your software, create a custom image from the boot volume, and use it to launch new instances.

C.Run a bash script via user data on every new instance launch to download and install the software every time.

D.Use Block Volume backups as direct instance templates without creating custom images.

AnswerB

This is the standard golden image creation process in OCI.

Why this answer

The workflow for custom software deployment involves launching a base image instance, installing and configuring your software, capturing a custom image from the boot volume, and using that custom image for future deployments.

Which THREE of the following actions can be performed using OCI Container Engine for Kubernetes (OKE)? (Choose three.)

Select 3 answers

A.Upgrading the Kubernetes control plane version independently of worker nodes

B.Running serverless container instances without any Kubernetes pod orchestration

C.Directly modifying the underlying Linux kernel parameters of the OKE-managed control plane master nodes

D.Automatically resizing worker node pools based on pod resource demands using the Cluster Autoscaler

E.Configuring node pools across multiple fault domains or availability domains

AnswersA, D, E

OKE decouples control plane upgrades from worker node upgrades.

Why this answer

OKE supports automated cluster upgrades, cluster autoscaling via cluster autoscaler, and configuring worker node pools across multiple fault domains or availability domains.

You have deployed an OCI Function and invoked it, but it returns a timeout error. What is the maximum execution timeout limit supported by OCI Functions?

A.Infinite

B.900 seconds (15 minutes)

C.60 seconds

D.3600 seconds (1 hour)

AnswerB

The maximum timeout for an OCI Function invocation is 900 seconds.

Why this answer

OCI Functions have a configurable timeout limit up to a maximum of 900 seconds (15 minutes).

Which OCI service feature enables you to automatically create identical compute instances based on an instance configuration and adjust the pool size based on demand?

A.Instance Pools and Autoscaling

B.Dedicated Virtual Machine Hosts

C.Compute Cluster Placement Groups

D.Managed File Storage

AnswerA

Instance pools manage groups of identical instances, and autoscaling adjusts their count based on demand.

Why this answer

Instance Pools combined with Autoscaling Configurations allow you to manage groups of identical instances and scale them automatically.

You have an OKE cluster and want to expose multiple HTTP and HTTPS microservices running in your cluster externally using a single public IP address and path-based routing. Which OCI native component should you deploy?

A.Internet Gateway directly attached to worker node pods

B.Service Gateway

C.OCI Network Load Balancer

D.OCI Load Balancer with Kubernetes Ingress Controller

AnswerD

The OCI Load Balancer Ingress Controller manages Layer 7 HTTP/HTTPS routing, SSL termination, and path-based routing.

Why this answer

OCI Load Balancer or Native Ingress Controller integrated with OCI Load Balancer allows you to route external traffic to different Kubernetes services based on paths or hostnames.

MCQeasy

Which command-line interface tool is used for managing core OCI infrastructure such as compute instances, VCNs, and block volumes?

A.kubectl

B.docker

C.fn

D.oci CLI

AnswerD

The oci CLI manages core OCI infrastructure services.

Why this answer

The `oci` CLI (OCI Command Line Interface) is the comprehensive tool used to manage core OCI services.

MCQhard

You are migrating a legacy application to OCI. The application requires a specific network interface card (NIC) virtualization mode and custom UEFI boot parameters that are not standard. Where should you configure these custom launch options?

A.Inside the VCN Security List configurations

B.Via the compute instance's operating system kernel parameters

C.In the Custom Image launch options settings

D.In the Instance Configuration template parameters

AnswerC

Launch options are defined at the custom image level to dictate firmware, network, and boot behavior.

Why this answer

Launch options can be customized when creating a custom image or by updating the launch options of an existing custom image in OCI to specify firmware, network virtualization, and boot options.
