Which 2 statements are valid regarding an OCI VCN? ›

Which two statements are valid regarding Virtual Cloud Network (VCN) peering between two VCNs? Peered VCNs can exist in the same OCI region. A VCN peering connection is a VPN-based connection. Peered VCNs can have overlapping CIDRs.

PCI DSS is a set of network security and business best practices guidelines adopted by the PCI Security Standards Council to establish a “minimum security standard” to protect customers' payment card information.

Instances in the public subnet have direct access to the internet by way of an internet gateway . Instances in the private subnet can initiate internet connections by way of a NAT gateway (for example, to get software updates), but cannot receive inbound connections from the internet through that gateway.

OCI has two specs, an Image spec and a Runtime spec.

OCI standard Intel-based VMs are 50% cheaper than equivalent Azure instances, Block Storage is 98% cheaper and data egress is 95% cheaper than Azure data egress (as of January 2021). Customers can realize significant savings moving their workloads to OCI.

Oracle Cloud Infrastructure offers over 70 cloud services, so we will cover only the high-level domains.

PCI compliance is a set of requirements designed to ensure the security of credit card information stored on computer systems. These standards were created by the payment industry to help prevent fraud and improve data security.

Which three 3 of these are PCI DSS requirements for any company handling? ›

A business or organization's PCI scope includes all people, processes, and technologies that "touch," interact with, or affect the security of cardholder data. With a proper understanding of PCI scope, you can ensure that your software products help you and your clients improve payment security.

Cost-based model, which merge the profit with the level of Cost. Value-Based, which take into consideration the basis of user perceiving value. Competition-based, which take into consideration the competitor price of services.

Cost Management supports four perpetual costing methods: Standard Costing, Average Costing, FIFO Costing, and LIFO Costing.

While Azure is the most expensive choice for general purpose instances, it's one of the most cost-effective alternatives to compute optimized instances.

So, to determine if a given subnet is public or private, you need to describe the route table that is associated with that subnet. That will tell you the routes and you can test for a 0.0. 0.0/0 route with a gateway ID of igw-xxxxxxxxxxxxxxxxx (as opposed to local ).

Subnet diagram

The following diagram shows two VPCs in a Region. Each VPC has public and private subnets and an internet gateway. You can optionally add subnets in a Local Zone, as shown in the diagram.

The OCI format is a specification for container images based on the Docker Image Manifest Version 2, Schema 2 format. Container Registry supports pushing and pulling OCI images.

What is OCI advantage and disadvantage? ›

The OCI card benefits refer to the rights you gain, like working rights, living as a resident, and entering India as many times as you want. One of the major drawbacks is that you must surrender your Indian passport as India doesn't accept dual citizenship.

The pricing methods can be broadly divided into two groups—cost-oriented method and market-oriented method.

This appears in two forms: the first, full cost pricing, takes into consideration both variable and fixed costs and adds a % markup. The other is direct cost pricing, which is variable costs plus a % markup.

Oracle OIC vs OCI

OIC runs on top of OCI. Whereas OCI stands for Oracle Cloud Infrastructure which is an IaaS and PaaS offering from Oracle which offers real-time elasticity for enterprise applications by combining Oracle's autonomous services, integrated security, and Serverless computing.

Simplify and automate security with our zero-trust approach. OCI is designed with a zero-trust, security-first architecture. Unlike AWS, OCI provides you with easy-to-implement security controls and automation to prevent misconfiguration errors and implement security best practices.

Customers choose OCI for performance and cost advantages

Runs security SaaS product on OCI to monitor thousands of workloads per customer. They're getting 60X better performance and 90% lower costs. Expects to reduce costs by 50% for its statewide ERP that supports 150,000 employees.

The Oracle Cloud Infrastructure (OCI) Database service offers autonomous and co-managed Oracle Database systems in the cloud. You can also manage Oracle Databases located outside the Oracle Cloud with OCI's External Database service.

Oracle Cloud offers services from 41 public cloud regions in 22 countries. Each Oracle Cloud region offers a consistent set of more than 100 cloud services designed to run any application, faster and more securely, for less. Oracle Datacenters are distributed around the world.

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. Users can launch instances with a variety of OSs, load them with custom application environments, manage network access permissions, and run images on multiple systems.

Level 1: Merchants that process over 6 million card transactions annually. Level 2: Merchants that process 1 to 6 million transactions annually. Level 3: Merchants that process 20,000 to 1 million transactions annually. Level 4: Merchants that process fewer than 20,000 transactions annually.

What is PCI compliance for dummies? ›

PCI standards present technical and operational requirements for protecting cardholder data. The standards apply to any organization that stores, processes or transmits cardholder data.

Never store the card-validation code or value (three- or four-digit number printed on the front or back of a payment card used to validate card-not-present transactions). Never store the personal identification number (PIN) or PIN Block.

Requirement 3.3 of the PCI DSS mandates organizations to mask PANs when they are displayed, ensuring: Truncated PAN cardholder data to display only a maximum of the first six and last four digits at any time. Only personnel with a legitimate business need can access entire PANs.

PCI Level 1: Businesses processing over 6 million transactions per year. PCI Level 2: Businesses processing 1 million to 6 million transactions per year. PCI Level 3: Businesses processing 20,000 to 1 million transactions per year. PCI Level 4: Businesses processing less than 20,000 transactions per year.

The following are the 4 levels of PCI compliance: Level 1: Merchants processing over 6 million card transactions per year. Level 2: Merchants processing 1 to 6 million transactions per year. Level 3: Merchants handling 20,000 to 1 million transactions per year.

IaaS, PaaS and SaaS are the three most popular types of cloud service offerings. They are sometimes referred to as cloud service models or cloud computing service models.

There are also three main types of cloud computing services: Infrastructure-as-a-Service (IaaS), Platforms-as-a-Service (PaaS), and Software-as-a-Service (SaaS). Choosing a cloud type or cloud service is a unique decision.

What are the 4 C in Oracle Apps? ›

Note: The 4 C's is defined as Chart of Accounts, Calendar, Currency, and accounting Convention.

The payment method can be electronic, such as EFT, bill payable, or wire, or printed, such as a check. You can use a payment method to pay one or multiple third-party payees. The purpose of creating disbursement payment methods is to: Define the disbursement payment methods you want to use to make payments.

Google Cloud tends to be the lowest price when no SSD is needed and the higest when SSD is required due to the price of adding on a 375 GB local SSD. Google Cloud is higher priced on the “per GB RAM” cost for highcpu due to the fact that it includes less than half the memory of AWS and Azure.

On-demand or pay-per-use pricing is the simplest and mostly the default option at cloud providers. Customers pay exactly what they use.

Google Cloud is much cheaper than AWS and Azure for computing optimized cloud-based instances. On the other hand, it's more expensive than others when it comes to the instance types of accelerated computing.

Which to which two statements are true about OCI compute service? It provides different sizes for different types of workloads and it provides options to create bare metal or a virtual machine.

Which statement is true about a Virtual Cloud Network (VCN)? Subnets can only be private.

Which two statements are true about Oracle Cloud Infrastructure (OCI) DB Systems? The database and backups are encrypted by default. Customers can consolidate multiple database homes on a single virtual machine database host.

What is the difference between Oracle OCI and OCI C? ›

Oracle OCI provides both Bare Metal & Virtual Machines (whereas OCI-C provides only Virtual Machine) [Updated on 15th Mar, Thanks Manjunath for pointing out typo] The hypervisor in VM option of OCI is based on KVM (whereas on OCI-C this is Xen based Hypervisor) Bring Your Own Hypervisor (BYOH) only available in OCI.

Can a private VCN have a public Subnet? Ans: VCN is a network (you don't define VCN as public or private), and only Subnets are defined as public and private. VCN can have both public and private Subnets.

Just like a traditional data center network, the VCN provides customers with complete control over their cloud networking environment. This includes assigning private IP address spaces, creating subnets and route tables, and configuring stateful firewalls.

The shared pool, which contains two main components. The library cache, which is a cache of SQL statements, etc. The dictionary cache, which caches Oracle own internal information, such as information about users and tables.

The Key Management service is integrated with many OCI services, including Block Volumes, File Storage, Oracle Container Engine for Kubernetes, and Object Storage.

In a VPC, both Security Groups and Network ACLs (NACLS) together help to build a layered network defence.

What is the difference between stateful and stateless OCI? ›

Stateful firewalls are capable of monitoring and detecting states of all traffic on a network to track and defend based on traffic patterns and flows. Stateless firewalls, however, only focus on individual packets, using preset rules to filter traffic.

There are two types of firewalls based on what they protect: network-based and host-based. Network-based firewalls, which are frequently hardware, protect entire networks. Host-based firewalls, which are frequently software, protect individual devices known as hosts.
