問題1

You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region. You were asked to create a disaster recovery (DR) plan that will protect against the loss of critical dat a. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public Internet.
Which is the recommended disaster recovery plan?

A. Create a DR environment in Ashburn. Associate a DRG with the VCN in each region and create a remote peering connection between the two VCNs.

B. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DR sites.

C. Create a DR environment in Ashburn and provision a FastConnect virtual circuit using DRG between the regions.

D. Create a DR environment in Ashburn. Associate a dynamic routing gateway (DRG) with the VCN in each region and configure an IPsec VPN connection between the two regions.

Which of the following action will the load balancer perform?

A. Terminate the instance that failed health check

B. Stop the instances that failed health check

C. Stop sending traffic to the instance that failed health check

D. Remove the instance that failed the health check from the backend set

問題4

You are tasked with creating a highly available clustered application on Oracle Cloud Infrastructure consisting of three nodes. The round-trip latency between nodes must be less than 500 µs (micro-seconds) and your cluster should be resilient to hardware failure.
What is the recommended deployment strategy?

A. Deploy the cluster nodes in a single region and deploy each node into a different AD.

B. Deploy the cluster nodes in a single region and deploy each node in different fault domains within a single AD.

C. Deploy the cluster nodes in a single region and deploy each node into a different AD. Select the same fault domain in each AD to ensure consistency.

D. Deploy the cluster nodes in two separate regions and take advantage of multiple availability domains (ADs) in each region.

正確答案: B

B. Primary and standby databases must be in the same OCI region.

C. Primary and standby database versions and editions need not be Identical.

D. Database systems need not be the same shape type (e.g, primary database can be a virtual machine, and standby database a bare metal shape, and vice versa).

A. It can be restored as a new volume to any AD across different regions

B. It can be restored as new volumes with different sizes from the backups

C. It can be restored as a new volume to any AD in the same region

D. It must be restored as a new volume to the same availability domain (AD) on which the original block volume backup resides

問題10

You have deployed a compute instance (VM.Standard2.24) to run an Oracle database. With this set up, you run into some performance issues and want to leverage an OCI Dense IO shape (VM.DenseIO2.24), with which you get 25.6 TB local NVMe SSD. You do not want to lose the configuration changes you made to the instance. Which of the following TWO steps ARE NOT required to make this transition?

A. Create a new instance using the VM.Dense102.24 shape using the preserved boot volume and move the Oracle Database data to NVMe disks

B. Terminate the VM.Standard2.24 instance and preserve the boot volume

C. Terminate the VM.Standard2.24 instance and do not preserve the boot volume

D. Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes
