Question 2

You want to deploy an OCI Function and test it locally on your developer workstation before pushing it to Oracle Functions Registry. Which command in the fn CLI initializes a new function project template?

Accepted Answer

fn init. The 'fn init' command initializes a new function project by scaffolding the required directory structure, including func.yaml, func.py (or other runtime handler), and requirements.txt. It is the first step before building or deploying a function with the fn CLI.

Answer

fn deploy --local

Answer

fn build local

Answer

fn create function

Question 3

Which TWO of the following are valid deployment models for Oracle Autonomous Database in OCI?

Accepted Answer

Autonomous Database on Shared Infrastructure. Option C, Autonomous Database on Shared Infrastructure, is correct because Oracle offers ADB in a shared (serverless) deployment model where the Exadata infrastructure and database are managed by Oracle and shared across tenants, with the customer only provisioning the database. Option E, Autonomous Database on Dedicated Exadata Infrastructure, is also correct because Oracle provides a dedicated deployment model where the customer provisions an Exadata Cloud@Customer or dedicated Exadata infrastructure in OCI, giving isolated, single-tenant Exadata hardware for the Autonomous Database. Options A and D are not valid because Oracle does not offer ADB on local block storage or on a standalone bare metal VM as named deployment models. Option B is not valid because Autonomous Database is not deployed on a customer's local on-premises Linux server; on-premises deployment is only available via Exadata Cloud@Customer, not a generic Linux server.

Answer

Autonomous Database on Local Block Storage

Answer

Autonomous Database on Local On-Premises Linux Server

Answer

Autonomous Database on Standalone Bare Metal VM

Question 4

You are configuring security for an Oracle Base Database Service instance in a private subnet. Which OCI networking construct should you configure to allow the database to download software patches from Oracle Object Storage without traversing the public internet?

Accepted Answer

Service Gateway. A Service Gateway in OCI provides private access from a VCN to Oracle services like Object Storage, so the database can download patches without using the public internet or a NAT gateway. Traffic stays on the Oracle network backbone, satisfying the private-subnet requirement.

Answer

Internet Gateway

Answer

Local Peering Gateway

Answer

NAT Gateway

Question 5

Which TWO of the following statements are true regarding OCI Compute Flexible Shapes? (Choose two.)

Accepted Answer

Flexible shapes support both AMD EPYC and Ampere ARM processor architectures.. Flexible shapes allow independent scaling of OCPUs and memory. They are available for both AMD and Ampere processor architectures across VM instances.

Answer

Flexible shapes are only available for Bare Metal instances and cannot be used with Virtual Machines.

Answer

Once a flexible compute instance is launched, its OCPU and memory allocations can never be modified.

Answer

Flexible shapes require a fixed ratio of 8 GB of RAM per 1 OCPU.

Question 6

Which THREE statements regarding OCI NAT Gateway behavior are correct?

Accepted Answer

Instances behind a NAT Gateway can initiate outbound connections to the internet.. NAT Gateways allow private subnet instances to initiate outbound connections to the internet, they scale automatically, and they do not accept inbound connections initiated from the internet.

Answer

NAT Gateways require compute instances to have public IP addresses.

Answer

NAT Gateways replace the need for an Internet Gateway in public subnets.

Question 7

Which THREE of the following are benefits of using OCI Object Storage?

Accepted Answer

High durability. Durability, scalability, and integration with IAM are key benefits.

Answer

Supports SQL queries natively

Answer

Latency lower than NVMe

Question 8

An Oracle Cloud Infrastructure (OCI) architect needs to provision a web application that must be accessible directly from the public internet. Which component must be attached to the Virtual Cloud Network (VCN) to allow inbound traffic from the internet?

Accepted Answer

Internet Gateway. An Internet Gateway is a routing component that connects the edge of a VCN with the public internet, enabling bidirectional communication for public resources.

Answer

Service Gateway

Answer

Dynamic Routing Gateway

Answer

NAT Gateway

Question 9

You have an Oracle Exadata Database Service on Dedicated Infrastructure. You need to scale the storage server grid independently of the compute servers to accommodate a massive data ingestion project. How should you accomplish this?

Accepted Answer

Add additional storage servers (storage cells) to the Exadata infrastructure resource.. Exadata Database Service on Dedicated Infrastructure allows independent scaling of storage servers and compute servers. To increase storage capacity and IOPS independently, you add storage cells to the Exadata infrastructure resource, which expands the ASM disk group without changing the compute node count.

Answer

Migrate the database to a Bare Metal DB system with larger local NVMe drives.

Answer

Scale up the Exadata VM cluster shape by adding more OCPUs.

Answer

Attach OCI Block Storage volumes directly to the Exadata database nodes via iSCSI.

Question 10

Which TWO networking components are required when establishing an OCI Site-to-Site VPN connection using dynamic routing (BGP)?

Accepted Answer

Dynamic Routing Gateway (DRG) configured with BGP ASN. Site-to-Site VPN with dynamic routing requires a CPE object, a DRG attached to the VCN, an IPSec connection with tunnels configured, and BGP ASN configuration on both the OCI side and CPE side.

Answer

Internet Gateway attached to private subnets

Answer

Local Peering Gateway (LPG)

Answer

NAT Gateway for BGP packet translation

Question 11

You have deployed an OCI VCN with a CIDR of 192.168.0.0/16. You want to peer this VCN with another VCN that has a CIDR of 192.168.64.0/18. Will this local peering succeed?

Accepted Answer

No, because the VCN CIDR blocks overlap.. Local peering between VCNs requires that their CIDR blocks do not overlap. Here, VCN1 has 192.168.0.0/16, which includes all addresses from 192.168.0.0 to 192.168.255.255. VCN2 has 192.168.64.0/18, which falls entirely within that range (192.168.64.0 to 192.168.127.255). Therefore, the CIDR blocks overlap, and local peering will fail.

Answer

Yes, as long as both VCNs are in the same compartment.

Answer

No, because VCNs must have identical CIDR sizes to peer.

Answer

Yes, because the second VCN CIDR is a subnet of the first.

Question 12

What is the maximum number of Fault Domains typically available within a single OCI Availability Domain?

Accepted Answer

3. OCI Availability Domains are divided into three Fault Domains by default, providing anti-affinity for high availability across physical hardware within an AD.

Answer

1

Answer

Unlimited

Answer

10

Question 13

Which THREE gateways can be attached to a Dynamic Routing Gateway (DRG) in OCI?

Accepted Answer

FastConnect Virtual Circuits. In OCI, a Dynamic Routing Gateway (DRG) is a virtual router that provides a path for private traffic between a VCN and destinations outside the VCN, and it can be attached to FastConnect Virtual Circuits (option A), which are the private virtual connections provisioned over an Oracle FastConnect partner or dedicated connection, enabling private connectivity between on-premises networks and OCI. A DRG can also be attached to Site-to-Site VPN (option C), where IPsec tunnels terminate on the DRG to provide encrypted connectivity between on-premises networks and the VCN. Additionally, a DRG can be attached to Virtual Cloud Networks (option E) via VCN attachments, which is the fundamental attachment that connects a VCN to the DRG so that traffic can be routed between the VCN and the other attached gateways. Local Peering Gateways (option B) are used to peer VCNs within the same region and attach to VCNs, not to a DRG, and Internet Gateways (option D) provide public internet access for a VCN and attach directly to a VCN, not to a DRG.

Answer

Local Peering Gateways

Answer

Internet Gateways

Question 14

You need to ensure that a resource's cost can be tracked. What must you do after defining a tag?

Accepted Answer

Enable it as a cost-tracking tag. You must navigate to the Cost Analysis page and enable the tag as a cost-tracking tag.

Answer

Attach it to a budget

Answer

Apply it to the compartment

Answer

Add it to the tenancy policy

Question 15

An OCI architect configures a Hub-and-Spoke architecture using DRG version 2. Hub VCN contains security appliances. Spoke VCN-A needs to inspect all outbound internet traffic through the security appliances in the Hub VCN before it hits the Internet Gateway. How should the Spoke VCN route table be configured?

Accepted Answer

Configure the Spoke VCN route table with 0.0.0.0/0 pointing to the DRG, and configure the DRG to route traffic to the Hub VCN security appliance.. To direct spoke internet traffic through a firewall appliance in the hub VCN, the spoke VCN subnet route table must have a route for 0.0.0.0/0 pointing to the DRG attachment, and the DRG route table routes that traffic to the hub security appliance VNIC.

Answer

Attach an Internet Gateway directly to the Spoke VCN private subnet.

Answer

Configure a NAT Gateway in every spoke VCN.

Answer

Use a Local Peering Gateway for internet inspection.
