You are the Cloud Architect of a company, and are designing a solution on Oracle Cloud Infrastructure where you want tohave all your compute instances resistant to hardware failure.
Which two are recommended best practices to achieve the requirement on Oracle Cloud Infrastructure?
(Choose two.)

• A.  Design your system with redundant compute modes in different Availability Domains to support the failover capability.
• B.  Create a custom image of your system drive each time you change the image.
• C.  Attach block volumes from different Availability Domains to compute instances in different Availability Domains for high availability.
• D.  Create backups of your block volumes that are associated with compute instances in different regions.

Within your tenancy you have a compute instance with a boot volume and a block volume attached. The boot volume contains the OS and the attached block volume contains the instance's important data. Logs on the boot volume have filled the boot volume and are causing issues with the OS.
What should you do to resolve this situation?

• A.  Stop the instance that is full. Create a manual backup of the block storage before making changes.
  Detach the block volume, create a new instance ofthe same shape with a larger custom boot volume and attach the block volume to the new instance. Configure the OS and any related application(s) to access the block volume under the same mount point as before.
• B.  Create a manual backup of the block storage instance. Create a custom imageof the full instance. Once that completes deploy the custom image to a new instance.
• C.  Detach the block volume from the full instance. Create a new instance of the same shape with a larger boot volume and rsync the state of the boot volume between the instances. Attach the block volume to the new instance.
• D.  Create a new instance with a larger boot volume size as well a new block volume which is the same size or larger than the one attached to the full instance. rsync the state of the boot volume and the state of the block volume between the two instances.

You are tasked with creating a highly available clustered application on Oracle Cloud Infrastructure consisting ofthree nodes. The round-trip latency between nodes must be less than 500 us (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 into a different AD. Select the same fault domain in each AD to ensure consistency.
• C.  Deploy the cluster nodes in a single region and deploy each node in different fault domains within a single AD.
• D.  Deploy the cluster nodes in two separate regions and take advantage of multiple availability domains (ADs) in each region.

Which statement is true about DB Systems?

• A.  You cannot manage the database as sys/sysdba.
• B.  You have full control over the automatic backup schedule and retention periods.
• C.  Data Guard as a Service is offered between regions.
• D.  You can manage Oracle database initialization parameters at a global level.

You have anexternal facing web server running in the Oracle Cloud Infrastructure (OCI) London region. You are notified that customers in North America and Australia are facing high latency while connecting to your web server.
Which services are available on OCI thatcan help you get current latency statistics to your web server from these markets?

• A.  Use DNS Zone Management service to check latency over that connection
• B.  Setup an IPsec VPN with customers in those markets and check latency over that connection
• C.  Setup a FastConnect with customers in those markets and check latency over that connection
• D.  Use the Internet Intelligence tool. Run tests using the web server's public IP address and review traceroute details from different vantage points
