You have been asked to set up connectivity between a client's on-premises network and Oracle Cloud

Infrastructure (OCI). The requirements are:

Low latency: The applications are financial and require low latency connectivity into OCI.

Consistency: The application isn't tolerant of performance variation.

Performance: The communications link needs to support up to 1.25 Gbps.

Encryption: The communications link needs to encrypt any data in transit between the on-premises

network and OCI Virtual Cloud Network (VCN).

The client wants to implement the above with as low a cost as possible, while meeting all of the

requirements. What should you suggest? (Choose the best answer.)

A. Provision FastConnect with a single private virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit.

B. Provision FastConnect with a single public virtual circuit.

C. Provision a site-to-site IPsec VPN between your on-premises network and your virtual cloud network (VCN) using VPN Connect.

D. Provision FastConnect with a single private virtual circuit.

E. Provision FastConnect with a single public virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit.

You have recently been asked to take over management of your company's infrastructure provisioning efforts, utilizing Terraform v0.12 to provision and manage infrastructure resources in Oracle Cloud Infrastructure (OCI). For the past few days the development environments have been failing to provision. Terraform returns the following error: You locate the related code block in the Terraform config and find the following:

Which correction should you make to solve this issue? (Choose the best answer.)

A. Place a command at the end of line 16

B. Modify line 15 to be the following: tcp_options = {min = “22”, max = “22”)

C. Modify line 15 to be the following: tcp_options { min = “22” max = “22” }

D. Replace the curly braces ‘{ }’ in lines 11 and 16 with square braces ‘[ ]’

You have been asked to review a network design for Oracle Cloud Infrastructure (OCI) by a major client. The client's IT team needs to provision two Virtual Cloud Networks (VCNs) for a major application. The application uses a large number of virtual machine instances. Additionally, in the future, a VCN peering will be required to allow connectivity between the VCNs.

Which of the following are valid IP ranges to consider? (Choose the best answer.)

A. 10.0.0.0/30 and 192.168.0.0/30

B. 10.0.0.0/8 and 11.0.0.0/8

C. 10.0.8.0/21 and 10.0.16.0/22

D. 10.0.0.0/16 and 10.0.64.0/24

Which statement about Oracle Cloud Infrastructure paravirtualized block volume attachments is TRUE? (Choose the best answer.)

A. Paravirtualized volumes may reduce the maximum IOPS performance for larger block volumes.

B. Paravirtualized is required to manage iSCSI configuration for virtual machine instances.

C. Paravirtualized volumes become immediately available on bare metal compute instances.

D. Paravirtualization utilizes the internal storage stack of compute instance OS and network hardware virtualization to access block volumes.

You are working as a Cloud Operations Administrator for your company. They have different Oracle Cloud Infrastructure (OCI) tenancies for development and production workloads. Each tenancy has resources in two regions – uk-london-1 and eu-frankfurt-1. You are asked to manage all resources and to automate all the tasks using OCI Command Line Interface (CLI).

Which is the most efficient method to manage multiple environments using OCI CLI? (Choose the best answer.)

A. Use OCI CLI profiles to create multiple sets of credentials in your config file, and reference the appropriate profile at runtime.

B. Create environment variables for the sets of credentials that align to each combination of tenancy, region, and environment.

C. Run oci setup config to create new credentials for each environment every time you want to access the environment.

D. Use different bash terminals for each environment.
