Question 7

Which THREE of the following statements are true regarding OCI Block Volume backups and performance? (Choose three.)

Accepted Answer

Block volume performance can be scaled independently of storage capacity by adjusting Volume Performance Units (VPUs).. Block Volume performance can be scaled independently using performance units, backups can be automated via policies, and volumes can be resized online.

Answer

Block volumes can only be attached to a single compute instance across multiple regions simultaneously.

Answer

Block volume backups are always full backups and incremental backups are not supported.

They require the manual installation and configuration of Kubernetes control plane nodes.

Answer

They are designed for long-running stateful multi-node container orchestration across 50 worker nodes.

Question 9

You are configuring a VCN and need to ensure that instances in a private subnet can access the internet to download updates without exposing them to incoming traffic. Which component is required?

Accepted Answer

NAT Gateway. A NAT Gateway allows instances in a private subnet to initiate outbound connections to the internet while preventing inbound connections.

Answer

Dynamic Routing Gateway

Answer

Service Gateway

Answer

Internet Gateway

Question 10

Your application team needs to store millions of small files that are rarely accessed but must be available immediately when requested. Which storage tier is most cost-effective?

Accepted Answer

Infrequent Access Storage. Infrequent Access tier in Object Storage is optimized for infrequently accessed data that requires immediate retrieval.

Answer

Archive Storage

Answer

Block Volume High Performance

Answer

Standard Storage

Question 11

An enterprise application deployed across multiple OCI subnets requires a Layer 4 load balancer that can handle millions of packets per second with ultra-low latency and preserve client source IP addresses. Which service should you deploy?

Accepted Answer

Network Load Balancer. Network Load Balancer (NLB) operates at Layer 4, handles high throughput and packet rates with low latency, and preserves source IPs.

Answer

OCI API Gateway

Answer

Dynamic Routing Gateway

Answer

Public Load Balancer (Layer 7)

Question 12

Which TWO statements are true regarding OCI Flexible Compute shapes? (Choose two.)

Accepted Answer

You can independently configure the number of OCPUs and memory (RAM) when launching a flexible VM.. Flexible compute shapes allow independent scaling of OCPUs and memory, and are available for both virtual machine and certain bare metal or specialized instance families.

Answer

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

Answer

Flexible shapes do not support boot volume resizing.

Answer

You must select a fixed tier of memory for every OCPU selected.

Question 13

Which OCI service enables you to run serverless functions triggered by events or HTTP requests without managing servers or runtimes?

Accepted Answer

OCI Functions. OCI Functions is a serverless platform enabling developers to deploy code that executes in response to events or HTTP requests.
