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?

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

Your customer has gone through a recent departmental re structure. As part of this change, they are organizing their Oracle Cloud Infrastructure (OCI) compartment structure to align with the company's new organizational structure.
They have made the following change:
Compartment x Is moved, and its parent compartment is now compartment c.

Policy defined in compartment A: Allow group networkadmins to manage subnets in compartment X Policy defined in root compartment: Allow group admins to read subnets in compartment Finance:A:X After the compartment move, which action will provide users of group networkadmins and admins with similar privileges as before the move?

• A.Define a policy in Compartment C as follows: Allow group network admins to manage subnets in compartment X.
• B.Define a policy in compartment HR as follows: Allow group network admins to manage subnets in compartment X.
• C.Define a policy in compartment C as follows: Allow group admins to read subnets in compartment HR:C:X
• D.Define a policy in compartment C as follows Allow group admins to read subnets in compartment HR:C:X
• E.No change in any policy statement is required as compartments move automatically moves alt the policy statements associated with compartments as well.

You are tasked with migrating an online shopping website to Oracle Cloud Infrastructure (OCI) and decide to use a Load Balancer. You have configured the backend set with the round robin policy. During the testing phase, you noticed that users are losing items from their shopping carts when they navigate to different pages.
How should you implement a solution to this problem?

• A.Set up session persistence at the Load Balancer backend set.
• B.Configure a set of path route rules that will route to different backend sets based on the URI requested by the customer's browser.
• C.Replace the round robin policy with least connections policy at the backend set.
• D.Set up a Traffic Management Steering Policy to redirect traffic to a different backend set that is deployed exclusively for the purpose of holding all Items placed in the shopping cart.

You are working with a customer who needs to attach an Oracle Cloud Infrastructure (OCI) block volume to a VM instance with read/write access type. The customer wants to know if the number of IOPS and throughput performance differs between the following two choices:
* Option A: attach a single 1 TB block volume to the VM instance
* Option B: attach two separate 500 GB block volumes In a RAID 0 array configuration to the VM instance You can assume that the customer is using iSCSI attachment type to attach the volumes to the instance. In addition, you can assume 1 MB block size for throughput and 4 KB block size for IOPS consideration.
How should you respond to the customer?

• A.Option B provides better IOPS and throughput performance.
• B.Option B provides higher level of throughput, but lower level of IOPS performance.
• C.Both options provide the same number of IOPS and throughput performance.
• D.Option A provides better IOPS, but lower throughput performance.

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?

• A.You are exceeding your volume group backup quota configured.
• B.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.
• C.The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
• D.Compute instance with multiple block volumes attached cannot move when a compartment is moved.
