Oracle Cloud Infrastructure 2022 Architect Professional - 1z0-997-22

You work for a bank as the lead Oracle Cloud Infrastructure architect. You designed a highly scalable solution for your company's banking application. The architecture includes a load balancer, application servers with autoscaling configuration based on CPU utilization, and an Autonomous Database with Transaction Processing workload type running in a Virtual Cloud Network (VCN).
During the peak utilization period, the application users complain that the application runs slow.
What are two possible reasons for the application running slow at times? (Choose two.)

• A. Instance pool in autoscaling configuration for the application servers did not scale out due to service limit breach of the VM shapes used by the application servers.
• B. Instance pool in autoscaling configuration for the Autonomous Database did not scale out due to misconfigured scaling policy.
• C. The VCN does not have a Network Security Group configured to allow traffic from the load balancer to all the application servers in the backend set.
• D. The load balancer is not configured correctly to send traffic to all the listeners of the application servers in the backend set.
• E. Instance pool in autoscaling configuration for the application servers did not scale out due to compartment quota breach of the VM shapes used by the application servers.

Which three scenarios are suitable for the Oracle Infrastructure (OCI) Autonomous transaction Processing Server less (ATP-S) deployment?

• A. A small startup is deploying a new application fen eCommerce and it requires database to store customers' transactions the team b of what the load will look like since it is a new application.
• B. A midsize company is considering migrating its legacy on premises MongoDB database to Oracle Cloud Infrastructure (OCI). The database has significantly higher workloads on weekends than weekdays
• C. A manufacturing company is running Oracle E-Business Suite application on premises. They are looking to move this application to OCI and they want to use a managed database offering for their database tier.
• D. A developer working on an Internal project needs to use a database during work hours but doesn't need It during nights or weekends. the project budget requires her to keep costs low.
• E. well established, online auction marketplace is running an application where there is database usage 24×7 but also has peaks of activity that the hard to predict when the peaks happen, the total activities may reach 3 times the normal activity level

A civil engineering company is running an online portal In which engineers can upload there constructions photos, videos, and other digital files.
There is a new requirement for you to implement: the online portal must offload the digital content to an Object Storage bucket for a period of 72 hours. After the provided time limit has elapsed, the portal will hold all the digital content locally and wait for the next offload period.
Which option fulfills this requirement?

• A. Create a pre-authenticated URL for the entire Object Storage bucket to read and list the content with an expiration of 72 hours.
• B. Create a pre authenticated URL lot each object that Is uploaded to the Object Storage bucket with an expiration of 72 hours.
• C. Create a pre authenticated URL for the entire Object Storage bucket to write content with an expiration of 72 hours.
• D. Create a Dynamic Group with matching rule for the portal compute Instance and grant access to the Object Storage bucket for 72 hours.

A fast growing E-commerce company has deployed their online shopping application on Oracle Cloud Infrastructure. The application was deployed on compute instances with Autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend. In order to promote their e-commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints.
What could be two possible reasons for this situation?

• A. Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.
• B. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation.
• C. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.
• D. As part of Autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change.

A company has an urgent requirement to migrate 100 TB of data to Oracle Cloud Infrastructure (OCI) in two weeks. They have a 100 Mbps Internet line but the connection is intermittent due to problems with their internet provider. In this scenario, what is the most time-efficient mechanism to migrate data to OCI?

• A. Set up an OCI Storage Gateway to connect your data center to your Virtual Cloud Network and upload data.
• B. Set up an IPSec VPN tunnel between your data center and OCI. Upload all data to OCI using OCI Storage Gateway.
• C. Set up hybrid network by launching a 1 Gbps FastConnect virtual circuit between your data center and OCI. Use OCI Object Storage multipart upload capability to automate the migration of your data to OCI.
• D. Upload data using OCI Object Storage multipart upload capability.
• E. Use OCI File Storage Service to copy data from your data center to OCI.
