Oracle 1Z0-997 問題集

質問 1：
A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They have decided to use both containers and servers technologies to run these application instances.
Which option should you recommend to build this new platform?
A. Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.
B. Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.
C. Install a kubernetes cluster on OCI and use OCI event service.
D. Use OCI functions, OCI object storage and OCI event service.
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

質問 3：
A retail company runs their online shopping platform entirely on Oracle cloud Infrastructure (OCI). This is a 3-tier web application that Includes a Mbps Load Balancer. Virtual Machine Instances for web and an Oracle DB Systems Virtual Machine Due to unprecedented growth, they noticed an Increase in the Incoming traffic to their website and all users start getting 503 (Service Unavailable) errors.
What is the potential problem in this scenario?
A. The Database Is down hence users can not access the web site
B. All the web servers are too busy and not able to answer any request from users.
C. The Traffic Management Policy is not set to load Balancer the traffic to the web servers.
D. The Load Balancer health check status Indicates critical situation for half of the backend webservers
E. You did not configure a Service Gateway to allow connection between web servers and load Balance

質問 4：
To serve web traffic for a popular product, your cloud engineer has provisioned four BM.Standard2.52 instances, event spread across two availability domains in the us-asburn-1 region: LoadBalancer is used to deliver the traffic across instances.
After several months, the product grows even more popular and you need additional compute capacity. As a result, an engineer provisioned two additional VM.Standard2.8 instances.
You register the two VM. Standard2. 8 Instances with your load Balancer Backend sot and quickly find that the VM Standard2.8 Instances running at 100% of CPU utilization but the BM.Standard2 .52 instances have significant CPU capacity that's unused.
Which option is the most cost effective and uses instances capacity most effectively?
A. Configure Autoscaling instance pool with LoadBalancer to add up to 3 more BM.Standard2.52 Instances when triggered. Shut off VM.Standard2.8 instances.
B. Route traffic to BM.Standard2.52 and VM Standard2.8 instances directly using DNS and Health Checks. Shut off the load Balances.
C. Configure your Load Balance, with weighted round robin policy to distribute traffic to the compute instances, with more weight assigned to bare metal instances.
D. Configure LoadBalancer with two VM Standard2.8 instances and use Autoscalling Instant pool to add up to two additional VM instances. Shut off BM.Standard2.52 instances.

A. Allow group VolumeAdmins to inspect volumes in tenancy
B. Allow group VolumeAdmins to manage volume-family In tenancy
C. Allow group VolumeAdmins to use volumes in tenancy
D. Allow group VolumeAdmins to copy volume' backups in tenancy

質問 6：
A customer has a Virtual Machine instance running in their Oracle Cloud Infrastructure tenancy. They realized that they wrongly picked a smaller shape for their compute instance. They are reaching out to you to help them fix the issue.
Which of the below options is best recommended to suggest to the customer?
A. Change the shape of the virtual machine instance using the Change Shape feature available in the console.
B. Change the shape of instance without reboot, but stop all the applications running on instance beforehand to prevent data corruption.
C. OCI doesn't allow such an operation.
D. Delete the running instance and spin up a new instance with the desired shape.
正解：A

質問 7：
All three Data Guard Configuration are fully supported on Oracle Cloud infrastructure (OCI). You want to deploy a maximum availability architecture (MAA) for database workload.
Which option should you consider while designing your Data Guard configuration to ensure best RTO and PRO without causing any data loss?
A. Configure ''Maximum Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in SYNC mode between two regions.
B. Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.
C. Configure "Maximum Protection" mode which provides zero data loss If the primary database fails.
D. Configure "Maximum Performance" mode In SYNC mode between two availability domains (same region) which provides, the highest level of data protection that is possible without affecting the performance of the primary database.
正解：A
