Oracle 1Z0-997-22 Online Questions & Answers

• Question 1:

  A retail company has several on-premises data centers which span multiple geographical locations. They plan to move some of their applications from on-premises data centers to Oracle Cloud Infrastructure (OCI). For these applications running in OCI, they still need to interact with applications running on their on-premises data centers to Oracle Cloud Infrastructure (OCI). for these applications running in OCI. they still need to interact with applications running on their on-premises data centers. These applications require highly available, fault-tolerant network connections between on premises data centers and OCI.

  Which option should you recommend to provide the highest level of redundancy?

  A. Oracle cloud Infrastructure provides network redundancy by default so that no other operations are required
  B. If your data centers span multiple, geographical locations, use only the specific IP address as a static route for the specific geographical location
  C. Set up both IPSec VPN and FastConnect to connect your on premises data centers to Oracle Cloud Infrastructure.
  D. Use FastConnect private peering only to ensure secure access from your data center to Oracle Cloud Infrastructure
  E. Set up a single IPSec VPN connection (rom your data center to Oracle Cloud Infrastructure since It is cost effective
  B. If your data centers span multiple, geographical locations, use only the specific IP address as a static route for the specific geographical location

  ---

  Explanation/Reference:

  If your data centers span multiple geographical locations, we recommend using a broad CIDR (0.0.0.0/0) as a static route in addition to the CIDR of the specific geographical location. This broad CIDR provides high availability and flexibility to your network design. For instance, the following diagram shows two networks in separate geographical areas that each connect to Oracle Cloud Infrastructure. Each area has a single on-premises router, so two IPSec VPN connections can be created. Note that each IPSec VPN connection has two static routes: one for the CIDR of the particular geographical area, and a broad 0.0.0.0/0 static route.

  

• Question 2:

  You are designing the network infrastructure for two application servers: appserver-1 and appserver-2 running in two different subnets inside the same Virtual Cloud Network (VCN) Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access appserver-1 from the internet and appserver-2 from the on-premises network. The on-premises network is connected to your VCN over a FastConnect virtual circuit.

  How should you design your routing configuration to meet these requirements?

  A. Configure a single routing table (Route Table-1) that has two set of rules. One that has route to internet via the internet Gateway and another that propagate specific routes for the on-premise network via the Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.
  B. Configure a single routing table (Routing Table-1) that has two set of rules: one that has route to internet via the Internet Gateway and another that propagates specific routes for the on-premises network via Dynamic Routing Gateway (DRG). Associate the routing table with the VCN.
  C. Configure two routing tables: Route Table-1 that has a route to internet via the Internet gateway. Associate this route table to the subnet containing appserver-1. Route Table-2 that propagate specific routes for the on-premises network via the Dynamic Routing Gateway (DRG) Associate this route table to subnet containing appserver-2.
  D. Configure two routing table (Route table-1 Route Table-2) that have rule to route all traffic via the Dynamic Routing Gateway (DRG) Associate the two routing tables with all the VCN subnets.
  C. Configure two routing tables: Route Table-1 that has a route to internet via the Internet gateway. Associate this route table to the subnet containing appserver-1. Route Table-2 that propagate specific routes for the on-premises network via the Dynamic Routing Gateway (DRG) Associate this route table to subnet containing appserver-2.

  Explanation/Reference:

  An internet gateway is an optional virtual router you can add to your VCN to enable direct connectivity to the internet. Resources that need to use the gateway for internet access must be in a public subnet and have public IP addresses. Each public subnet that needs to use the internet gateway must have a route table rule that specifies the gateway as the target. For traffic to flow between a subnet and an internet gateway, you must create a route rule accordingly in the subnet's route table (for example, destination CIDR = 0.0.0.0/0 and target = internet gateway). Dynamic Routing Gateway (DRG) is A virtual edge router attached to your VCN. Necessary for private peering. The DRG is a single point of entry for private traffic coming in to your VCN,After creating the DRG, you must attach it to your VCN and add a route for the DRG in the VCN's route table to enable traffic flow.

• Question 3:

  A FinTech startup is developing a new blockchain based application to provide Smart Contracts using micro-services architecture. The development team is planning to deploy the application using containers and looking for a reliable way to build, deploy and manage their cloud-native application.

  Additionally, they need an easy way to store, share and manage their application artifacts.

  Which option should you recommend for this application?

  A. Install and manage a Kubernetes cluster on OCI Compute Instances and use OCI Resource Manager for management of application artifacts
  B. Use and OCI Resource Manager to manage cloud-native application and make the application artifacts available using OCI Functions
  C. Use Oracle Container Engine for Kubernetes (OKE) to manage of cloud-native applications and OCI Registry for application artifacts
  D. Use Oracle Container Engine for Kubernetes (OKE) to manage the deployment environment and OCI Functions for application artifacts
  C. Use Oracle Container Engine for Kubernetes (OKE) to manage of cloud-native applications and OCI Registry for application artifacts

  ---

  Explanation/Reference:

  Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy.

  Oracle Cloud Infrastructure Registry is an Oracle-managed registry that enables you to simplify your development to production workflow. Oracle Cloud Infrastructure Registry makes it easy for you as a developer to store, share, and manage development artifacts like Docker images. And the highly available and scalable architecture of Oracle Cloud Infrastructure ensures you can reliably deploy your applications.

  So you don't have to worry about operational issues, or scaling the underlying infrastructure.
