Oracle 1Z0-997 問題集

質問 1：
You are helping a customer troubleshoot a problem. The customer has several Oracle Linux servers in a private subnet within a Virtual Cloud Network (VCN). The servers are configured to periodically communicate to the Internet to get security patches for applications Installed on them.
The servers are unable to reach the Internet. An Internet Gateway has been deployed In the public subnet in the VCN and the appropriate routes are configured in the Route Table associated with the public subnet.
Based on cost considerations, which option will fix this Issue?
A. Create a NAT gateway in the VCN and configure the NAT gateway as the route target for the private subnet.
B. Create a Public Load Balancer In front of the servers and add the servers to the Backend Set of the Public Load Balancer.
C. Create another Internet Gateway and configure it as route target for the private subnet.
D. Implement a NAT instance In the public subnet of the VCN and configure the NAT instance as the route target for the private subnet.
正解：B

質問 2：
You work for a German company as the Lead Oracle Cloud Infrastructure architect. You have designed a highly scalable architecture for your company's business critical application which uses the Load Balancer service auto which uses the Load Balancer service, autoscaling configuration for the application servers and a 2 Node VM Oracle RAC database. During the peak utilization period of the- application yon notice that the application is running slow and customers are complaining. This is resulting in support tickets being created for API timeouts and negative sentiment from the customer base.
What are two possible reasons for this application slowness?
A. The Load Balancer configuration is not sending traffic to the listener of the application servers.
B. Autoscaling configuration for the application servers didn't happen due to service limit breach of the VM shapes used by the application servers
C. Autoscaling configuration for the application servers didn't happen due to compartment quota breach of the VM shapes used by the application servers.
D. Autoscaling configuration for the application servers didn't happen due to 1AM policy that's blocking access to the application server compartment
E. The Load Balancer doesn't have a Network Security Group to allow traffic to the application servers.
正解：B,C

The Finance department of your company has reached out to you. They have customer sensitive data on compute Instances In Oracle Cloud Infrastructure (OCI) which they want to store in OCI Storage for long term retention and archival.
To meet security requirements they want to ensure this data is NOT transferred over public internet, even if encrypted.
which they want to store In OCI Object Storage fin long term retention and archival To meet security requirements they want to ensure this data is NOT transferred over public Internet, even it encrypted.
Which option meets this requirements?
A. Use Storage gateway with appropriate firewall rule.
B. Configure a NAT instance and all traffic between compute In Private subnet should use this NAT instance with Private IP as the route target.
C. Use NAT gateway with appropriate route table when transferring data. Then use NAT gateways' toggle (on/off) once data transfer is complete.
D. Use Service gateway with appropriate route table.

質問 4：
An Oracle Cloud Infrastructure (OCI) Public Load Balancer's SSL certificate is expiring soon. You noticed the Load Balancer is configured with SSL Termination only. When the certificate expires, data traffic can be interrupted and security compromised.
What steps do you need to take to prevent this situation?
A. Add the new SSL certificate to the Load Balancer, update listeners and backend sets so they can use the new certificate bundle.
B. Add the new SSL certificate to the Load Balancer and update backend servers to use the new certificate bundle.
C. Add the new SSL certificate to the Load Balancer and update listeners to use the new certificate bundle.
D. Add the new SSL certificate to the Load Balancer, update backend servers to work with a new certificate and edit listeners so they can use the new certificate bundle.
E. Add the new SSL certificate to the Load Balancer and implement end to end SSL so it can encrypt the traffic from clients all the way to the backend servers.
正解：D

質問 7：
A company has an urgent requirement to migrate 300 TB of data to Oracle Cloud Infrastructure (OCI) In two weeks. Their data center has been recently struck by a massive hurricane and the building has been badly damaged, although still operational. They have a 100 Mbps Internet line but the connection is Intermittent due to the damages caused to the electrical grid in this scenario, what is the most effective service to use to migrate the data to OCI given the time constraints?
A. Use multiple OCI Data Transfer Appliances to transfer data to OCI.
B. Upload the data to OCI using OCI Object Storage multipart upload tool.
C. Setup a OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI using OCI Storage Gateway Cloud Sync tool.
D. Setup a hybrid network by launching aIGbpsFastConnect virtual circuit between your data center and OCI. Use OCI Object storage multipart upload tool to automate the migration of your data to OCI.
E. Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI.
