QUESTION 14
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?

Autoscaling configuration for the application servers didn’t happen due to IAM policy that’s blocking access to the application server compartment

The Load Balancer configuration is not sending traffic to the listener of the application servers.

Autoscaling configuration for the application servers didn’t happen due to compartment quota breach of the VM shapes used by the application servers.

Autoscaling configuration for the application servers didn’t happen due to service limit breach of the VM shapes used by the application servers

The Load Balancer doesn’t have a Network Security Group to allow traffic to the application servers.

QUESTION 15
Which of the following is NOT a good use case for the volume backup feature of the Oracle Cloud Infrastructure Block Volume service?

Support business continuity requirements of reducing the risk of outages or data mutation over time.

Meet compliance and regulatory requirements for data to remain unchanged over time, so that it can be retrieved for audit purposes.

Rapidly duplicate an environment in seconds to test configuration changes without impacting your production environment.

Retain a copy of data in a volume, so that you can duplicate an environment later or preserve the data for future use.

QUESTION 16
An upcoming e-commerce company has deployed their online shopping application on OCI. 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?

The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation

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

The health check on some of the backend servers has failed and the load balancer was rebooting these servers.

The autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room of scaling

QUESTION 17
You are tasked with building a highly available, fault tolerant web application for your current employer. The security team is concerned about an increase in malicious web-based attacks across the internet and asked what you can do to add a higher level of security to the website.
How should you architect the solution on Oracle Cloud Infrastructure (OCI) to meet all requirements defined by your organization? (Choose the best answer.)

Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Deploy a Web Application Firewall (WAF) and configure the load balancer public IP address as the origin.

Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Create a Geolocation steering policy in Traffic Management and add an answer pool that directs to the public IP address of the load balancer. Configure a global catch-all rule to use this answer pool.

Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Ensure that each web application server is assigned a public IP address. Deploy a Web Application Firewall (WAF) and configure one Origin for each public IP address.

Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Use the OCI Traffic Management service to create a load balancing policy that will resolve DNS evenly between all web servers.

QUESTION 18
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?

The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation.

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.

The health check on some of the backend servers has failed and the load balancer was rebooting these servers.

Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.

QUESTION 19
You are part of a project team working in the development environment created in OCI. You have realized that the CIDR block specified for one of the subnet in a VCN is not correct and want to delete the subnet. While deleting you are getting an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet.
Which of the following action you will take to troubleshoot this issue?

Use OCI CLI to call “GetVnic” operation to find out the parent resource of the VNIC

Copy and Paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC

Use OCI CLI to delete the VNIC first and then delete the subnet

Use OCI CLI to delete the subnet using –force option

QUESTION 20
You are responsible for migrating your on premises legacy databases on 11.2.0.4 version to Autonomous Transaction Processing Dedicated (ATP-D) In Oracle Cloud Infrastructure (OCI). As a solution architect, you need to plan your migration approach.
Which two options do you need to implement together to migrate your on premises databases to OCI?

QUESTION 24
You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use Volume Group’s feature. The Block volume and Compute instances exist in different compartments within your tenancy.
Periodically. a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.
What could be the cause?

You are exceeding your volume group backup quota configured.

You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.

Compute instance with multiple block volumes attached cannot move when a compartment is moved.

The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
