Correct Answer: B

Network Security Groups (NSGs) act as virtual firewalls in OCI, controlling inbound and outbound traffic for specific resources within a VCN. You can define rules based on IPs, ports, and protocols.

Correct Answer: D

High-performance computing (HPC) typically involves complex calculations and processing, which are not optimized for Oracle Autonomous Database on Shared Exadata Infrastructure. HPC often requires specialized hardware and configurations for optimal performance.

Correct Answer: C

This statement is NOT true. Compartments in Oracle Cloud Infrastructure do not provide a way to store and manage encryption keys and secrets. This functionality is typically handled by other services such as Key Management.

Correct Answer: D

OCI Functions automatically handles operating system patches and upgrades, ensuring that the functions are secure and up-to-date without requiring manual maintenance from users.

Correct Answer: B

Correct Answer: C

When you sign up for Oracle Cloud Infrastructure, Oracle creates a tenancy for you in one region. This is your home region. Your home region is where your IAM resources are defined. When you subscribe to another region, your IAM resources are available in the new region, however, the master definitions reside in your home region and can only be changed there. When you subscribe your tenancy to a new region, all the policies from your home region are enforced in the new region. If you want to limit access for groups of users to specific regions, you can write policies to grant access to specific regions only. Reference: https://docs.cloud.oracle.com/en-us/iaas/Content/Identity/Tasks/managingregions.htm

To create an instance in another region, perform these preliminary steps:

1.

Extend your subscription to another region.

2.

Federate Oracle Identity Cloud Service (IDCS) from the new region with Oracle Cloud Infrastructure (OCI).

Also, when you purchase these services or sign up for a free promotion, you typically choose the data region closest to your location to access them. This becomes your primary data region. However, if required, you can extend your

subscription to other geographical regions (within the same cloud account) and use the services there.

Correct Answer: C

Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine. An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.

With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool -- Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and

comes with an upper limit.

Correct Answer: AD

Oracle Cloud Infrastructure's security approach is based on seven core pillars. Each pillar has multiple solutions designed to maximize the security and compliance of the platform and to help customers to improve their security posture. High Availability: Offer fault-independent data centers that enable high-availability scale-out architectures and are resilient against network attacks, ensuring constant uptime in the face of disaster and security attack. Customer Isolation: Allow customers to deploy their application and data assets in an environment that commits full isolation from other tenants and Oracle's staff. Data Encryption: Protect customer data at-rest and in-transit in a way that allows customers to meet their security and compliance requirements with respect to cryptographic algorithms and key management. Security Controls: Offer customers effective and easy-to-use application, platform, and network security solutions that allow them to protect their workloads, have a secure application delivery using a global edge network, constrain access to their services, and segregate operational responsibilities to reduce the risk associated with malicious and accidental user actions. Visibility: Offer customers comprehensive log data and security analytics that they can use to audit and monitor actions on their resources, allowing them to meet their audit requirements and reduce security and operational risk. Secure Hybrid Cloud: Enable customers to use their existing security assets, such as user accounts and policies, as well as third-party security solutions, when accessing their cloud resources and securing their data and application assets in the cloud. Verifiably Secure Infrastructure: Follow rigorous processes and use effective security controls in all phases of cloud service development and operation. Demonstrate adherence to Oracle's strict security standards through third- party audits, certifications, and attestations. Help customers demonstrate compliance readiness to internal security and compliance teams, their customers, auditors, and regulators.

Correct Answer: A

The Oracle Cloud Infrastructure Domain Name System (DNS) service lets you create and manage your DNS zones. You can create zones, add records to zones, and allow Oracle Cloud Infrastructure's edge network to handle your domain's DNS queries.
