1. Question 1 · 1

   A consulting company that employs Oracle Cloud Infrastructure (OCI) architects has successfully completed resource migration from Microsoft Azure to OCI, and no longer requires the OCI FastConnect circuit to Azure. The project manager has asked you to delete all resources involved in this inter-cloud connectivity. From the Azure side, you delete the Resource Group. After a while, you notice that all Azure resources have been deleted, except for the Azure ExpressRoute circuit. What could be a potential reason for this issue?

   Choose one answer.

   • You need to first delete the OCI FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit.
   • Your bill from the OCI side needs to be paid in full before you can remove the Azure ExpressRoute circuit.
   • You need to remove all routes that point to the inter-cloud connection on both OCI and Azure before you can delete the circuit.
   • You need to remove the Azure ExpressRoute Partner Service Key from the OCI FastConnect circuit, and then you can delete the ExpressRoute virtual circuit.

11. Question 11 · 1

    To serve web traffic for a popular product, your cloud engineer has provisioned four BM.Standard2.52 instances, evenly spread across two availability domains in the us-ashburn-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 set and quickly find that the VM.Standard2.8 instances are now 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?

    Choose one answer.

    • Configure LoadBalancer with two VM.Standard2.8 instances and use Autoscaling instance pool to add up to two additional VM.Standard2.8 instances. Shut off BM.Standard2.52 instances.
    • Configure your Load Balancer with weighted round robin policy to distribute traffic to the compute instances, with more weight assigned to bare metal instances.
    • Configure Autoscaling instance pool with LoadBalancer to add up to 3 more BM. Standard2.52 Instances when triggered, Shut off VM.Standard2.8 Instances.

13. Question 13 · 1

    A company runs a public-facing application that uses a Java-based web service via a RESTful API in their on-premises data center. Use of the API is expected to double with a new product launch. The business wants to migrate their application to Oracle Cloud Infrastructure (OCI) to meet the scale and reliability requirements. In order to achieve this, they will divert only 40% of the traffic to the new Apache Tomcat web servers running on OCI and serve the remaining 60% traffic through their on-premises infrastructure. Once the migration is complete and application works fine, they will divert all traffic to OCI. How can these requirements be met with the LEAST amount of effort?

    Choose one answer.

    • Set up a VPN connectivity between on-premises infrastructure and OCI and create routing tables to distribute traffic between them.
    • Use OCI Traffic management service with Failover steering policy and distribute traffic between OCI and on-premises infrastructure.
    • Use OCI Load Balancing service to distribute traffic between OCI and on-premises infrastructure.
    • Use OCI Traffic management service with Load Balancing steering policy and distribute traffic between OCI and on-premises infrastructure.

14. Question 14 · 1

    Your company will soon start moving critical systems into the Oracle Cloud Infrastructure (OCI) platform. These systems will reside in the us-phoenix-1 and us-ashburn-1 regions. As part of the migration plan, you review the company's existing security policies and written guidelines for the OCI platform usage within the company. Your security processes for critical systems require that all data be encrypted at rest using Customer-Managed Keys. Which TWO options ensure compliance with this policy? (Choose two.)

    Choose all answers that apply.

    • When you create a new compute instance through the OCI console, use the default options for "configure boot volume" to speed up the process of creating this compute instance.
    • When you create a new compute instance through the OCI console, use the default shape to speed up the process of creating this compute instance.
    • When you create a new OCI Object Storage bucket through the OCI console, you need to choose the "ENCRYPT USING CUSTOMER-MANAGED KEYS" option.
    • When you create a new block volume through the OCI console, select the "Encrypt using Customer-Managed Keys" checkbox and use the encryption keys generated and stored in OCI Vault.
    • You do not need to perform any additional actions because the OCI Block Volume service always encrypts all block volumes, boot volumes, and volume backups at rest by using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption.

15. Question 15 · 1

    Given this compartment structure: You are managing a compute instance that currently resides in the Compute compartment. The Virtual Cloud Network (VCN) into which the compute instance was originally deployed, also resides in this compartment. To support a project-related task, you need to move just the compute instance to the SysTest-Team compartment. You log into your Oracle Cloud Infrastructure (OCI) account and use the Move Resource option to place the compute instance in the new compartment. What will be the result of your attempt to move the compute instance to the new compartment?

    Choose one answer.

    

    • The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the compute instance can be moved.
    • After moving the compute instance, you must move the compute instance VNIC as a separate action. The public and private IP addresses of the instance will remain unchanged and it will still be associated with the VCN from the source compartment.
    • The move will be successful. The compute instance's public and private IP addresses will stay the same. The compute instance will remain associated with the VCN from the source compartment.
    • The move will be successful. However, the compute instance's public and private IP addresses will change, and it will be associated to the first VCN that was created in the new, target compartment.
