문제3
A retail company has several on-premise data centers which span multiple geographical locations. They plan to move many of their business critical applications to Oracle Cloud Infrastructure (OCI). These applications require highly available network connections between on-premises and OCI.
Which option provides the highest level of redundancy?

A. Use either a Site-to-Site VPN or FastConnect connection to connect to an on-premises edge device, since OCI provides network redundancy by default.

B. Set up both Site-to-Site VPN and Fast Connect connections from OCI to separate edge devices on-premises.

C. Use transit routing by deploying a hub Virtual Cloud Network (VCN) in OCI peered with application VCNs as spokes, and with an on-premises edge device with two redundant tunnels in Site-to-Site VPN.

D. Set up Site-to-Site VPN connection with two redundant tunnels from the on-premises edge device to OCI.

E. Set up Fast Connect with the colocation with Oracle option, and a compatible edge device on- premises.

정답: B

문제4

문제5
An E-commerce company which sells computers, tablets, and other electronics items has recently decided to move all of their on-premises infrastructure to Oracle Cloud Infrastructure (OCI). One of their on-premises application is running on an NGINX server and the Oracle Database is running in a 2 node Oracle Real Application Clusters (RAC) configuration.
They cannot afford to have any application down time when they do the migration.
What is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?

A. Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Import the on-premises database to OCI VM DB Systems using Oracle Data Pump and then enable automatic backups.

B. Launch a compute instance for both the NGINX application server and the database server. Attach block volumes on the database server compute instance and enable backup policy to backup the block volumes.

C. Launch a compute instance and run an NGINX server to host the application. Deploy Exadata Quarter Rack, enable automatic backups and import the database using Oracle Data Pump.

D. Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Setup Oracle GoldenGate to synchronize data from their on-premises database to OCIVM Database. Export and Import the on-premises database to OCIVM DB Systems using Oracle Data Pump, apply the GoldenGate trail files to sync up the OCI database with the on-premises database. Enable automatic backups for the OCIVM database and then cutoverthe application from on-premises to OCI.

정답: D

문제6
You work for a large bank where your main application is a payment processing gateway API. You deployed the application on Oracle Container Engine for Kubernetes (OKE) and used API Gateway with several policies to control the access of the API endpoint.
However, your customers are complaining about the unavailability of the API endpoint. Upon checking, you noticed that the Gateway URL is throwing Service Unavailable error. You need to check the backend latency and backend responses when this error started last night.
What should you do to get this data? (Choose the best answer.)

A. Go to Governance Menu and click on Audit to see the Audit log for the API Gateway. Filter it using Start and End date with a 503 response status.

B. Go to Monitoring and click on Service Metrics. Choose the Metric Namespace as oci_apigateway. Change the Start and End time accordingly. Add a Dimension and select httpStatusCode: 503. Check the backend latency and backend responses metric.

C. Check with the application owner and search the log file for the container to get the metrics from the log file.

D. Go to Developer Services and click on API Gateway. Go to the detail page of the gateway and select Metrics. Change the Start and End time to filter the metrics.

문제7
You have decided to migrate your application to Oracle Cloud Infrastructure and use Oracle Functions to deploy your microservices.
Which monitoring metrics are available to help you calculate your total cost for using Oracle Functions per month? (Choose Two)

A. Network bandwidth used by your functions.

B. Length of time a function runs.

C. Number of times a function is invoked.

D. Amount of storage used by your functions.

문제8
You developed a microservices-based application that runs on Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). It has multiple endpoints that needs to be exposed to the public internet.
What is the most cost-effective way to expose multiple application endpoints without adding complexity to the application?

A. Deploy an Ingress Controller and use it to expose each endpoint with its own routing endpoint.

B. Use ClusterIP service type in Kubernetes for each of your service endpoint and use a load balancer to expose the endpoints.

C. Use NodePort service type in Kubernetes for each of your service endpoint and use node's public IP address to access the applications.

D. Use separate load balancer instance for each service, but use the 100 Mbps load balancer option.

정답: A

문제9
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 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.

D. 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.

문제10
You are working as a solution architect for an online retail store to create a portal to allow the users to pay for their groceries using credit cards. Since the application is not fully compliant with the Payment Card Industry Data Security Standard (PCI DSS), your company is looking to use a third party payment service to process credit card payments.
The third party service allows a maximum of Spelunk IP addresses 5 public IP addresses at a time However, your website is using Oracle Cloud Infrastructure (OCI) Instance Pool Auto Scaling policy to create up to create up to 15 Instances during peak traffic demand, which are launched In VCN private in VCN private subnets and attached to an OCI public Load Balancer. Upon user payment, the portal connects to the payment service over the Interne! to complete the transaction What solution can you implement to make sure that all compute Instances can connect to the third party system to process the payments aw peak traffic demand?

A. Whitelist the Internet Gateway Public IP on the third party service and route all payment requests through the Internet Gateway.

B. Route credit card payment request from the compute instances through the NAT Gateway. On the third-party services, whitelist the public IP associated with the NAT Gateway.

C. Route payment request from the compute instances through the OCI Load Balancer, which will then be routed to the third party service.

D. Create an OCI Command Line Interface (CLI) script to automatically reserve public IP address for the compute instances. On the third-party services, whitelist the Reserved public IP.
