Which TWO statements are TRUE about Public IP addresses in Oracle CloudInfrastructure (OCI)?

12. You are backing up your on- premises data to Oracle Cloud Infrastructure (OCI) ObjectStorage Service.RequirementBackups are retained for at-least full 31 days.You must be able to access the data immediately if and when needed after the backup.

13. Which TWO are benefits of Oracle Cloud Infrastructure Transit Routing?Choose all correct answers.It enables access to Oracle Services using public internet.It enables customers to connect several VNCs to a single Dynamic Routing Gateway.It enables public access for your on-premises applications to Oracle services.It enables communication between an on-premises network and multiple VCNs in thesame region over a single FastConnect private virtual circuit or Site-to-Site VPN.

Transit routing can be defined as a network topology in which on-premises network uses a connected virtual cloud network (VCN) to reach Oracle resources or services beyond that VCN. You connect the on-premises network to the VCN with FastConnect or VPN Connect, and then configure the VCN routing so that traffic transits through the VCN to its destination beyond the VCN.

Which 2 are benefits of OCI transit routing?

There are two primary transit routing scenarios: –

  • This scenario enables communication between on-premises network and multiple VCNs in the same region over a single FastConnect private virtual circuit or VPN Connect.
  • Private access to Oracle services: This scenario gives on-premises network private access to Oracle services, so that on-premises hosts can use their private IP addresses and the traffic does not go over the internet.

What is transit routing in Oracle Cloud?

Transit routing refers to a network topology in which your on-premises network uses an intermediary to reach Oracle resources or services or VCNs. The intermediary can be a VCN or a dynamic routing gateway (DRG) your on-premises network is already attached to.

What purpose does an OCI dynamic routing gateway serve?

A dynamic routing gateway (DRG), which is a virtual router that provides a path for private network traffic between your VCN and your existing network. You use it with other Networking Service components to create an IPSec VPN or a connection that uses Oracle Cloud Infrastructure FastConnect.

Which two Oracle cloud infrastructure services use a dynamic routing gateway choose two?

Dynamic Routing Gateways (DRGs).
Remote Peering Connections..
Site-to-Site VPN IPSec tunnels..
Oracle Cloud Infrastructure FastConnect virtual circuits..

What are two uses cases to use FastConnect when connecting to a virtual cloud network?

Uses for FastConnect.
Private peering: To extend your existing infrastructure into a virtual cloud network (VCN) in Oracle Cloud Infrastructure (for example, to implement a hybrid cloud, or a lift and shift scenario). ... .
Public peering: To access public services in Oracle Cloud Infrastructure without using the internet..
