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

A global retailer is setting up the cloud architecture to be deployed in Oracle Cloud infrastructure (OCI) which will have thousands of users from two major geographical regions: North America and Asia Pacific. The requirements of the services are:
* Service needs to be available 27/7 to avoid any business disruption
* North American customers should be served by application running In North American regions
* Asia Pacific customers should be served by applications running In Asia Pacific regions
* Must be resilient enough to handle the outage of an entire OCI region

• A.OCl DNS, Traffic Management with Geolocation steering policy. Health Checks
• B.OCl DNS, Traffic Management with Failover steering policy
• C.OCl DNS, Traffic Management with Geolocation steering policy
• D.OCl DNS,' Traffic Management with Load Balancer steering policy, Health Checks

You have provisioned a new VM.DenseIO2.24 compute instance with local NVMe drives. The compute instance is running production application. This is a write heavy application, with a significant Impact to the business it the application goes down.
What should you do to help maintain write performance and protect against NVMe devices failure.

• A.NVMe drive have built in capability to recover themself so no other actions are required
• B.Configure RAID 6 for NVMe devices.
• C.Configure RAID 1 for NVMe devices.
• D.Configure RAID 10 for NVMe devices.

A new international hacktivist group, based in London, launched wide scale cyber attacks including SQL Injection and Cross-Site Scripting (XSS) across multiple websites which are hosted in Oracle Cloud Infrastructure (OCI). As an IT consultant, you must configure a Web Application Firewall (WAF) to protect these websites against the attacks.
How should you configure your WAF to protect the website against those attacks? (Choose the best answer.)

• A.Enable a Protection Rule to block requests that came from London.
• B.Enable a Protection Rule to block the attacks based on HTTP Headers that contain XSS and SQL strings.
• C.Enable an Access Rule that contains XSS Filters Categories and SQL Filters Categories.
• D.Enable a Protection Rule that contains XSS Filters Categories and SQL Filters Categories.
• E.Enable an Access Rule to block the IP Address range from London.

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.Route traffic to BM.Standard2.52 and VM Standard2.8 instances directly using DNS and Health Checks. Shut off the load Balances.
• B.Configure Autoscaling instance pool with LoadBalancer to add up to 3 more BM.Standard2.52 Instances when triggered. Shut off VM.Standard2.8 instances.
• 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.
