Which two are true for achieving High Availability on Oracle Cloud Infrastructure? (Choose two.)

• A.Store your database across multiple regions so that half of the data resides in one region and the other half resides in another region.
• B.Distribute your application servers across all Availability Domains within a region.
• C.Store your database files on Object Storage so that they are available in all Availability Domains in all regions.
• D.Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
• E.Attach your block volume form Availability Domain 1 to a compute instance in Availability Domain 2 (and vice versa) so that they are highlyavailable.

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 data. 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 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.
• B.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.
• 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.

Correct Answer: B

Explanation
Remote VCN peering is the process of connecting two VCNs in different regions (but the same tenancy ). The peering allows the VCNs' resources to communicate using private IP addresses without routing the traffic over the internet or through your on-premises network. Without peering, a given VCN would need an internet gateway and public IP addresses for the instances that need to communicate with another VCN in a different region.
At a high level, the Networking service components required for a remotepeering include:
- Two VCNs with non-overlapping CIDRs, in different regions that support remote peering. The VCNs must be in the same tenancy.
- A dynamic routing gateway (DRG) attached to each VCN in the peering relationship. Your VCN already has a DRG if you're using an IPSec VPN or an Oracle Cloud Infrastructure FastConnect private virtual circuit.
A remote peering connection (RPC) on each DRG in the peering relationship.
A connection between those two RPCs.
Supporting route rules to enable traffic to flow over the connection, and only to and from select subnets in the respective VCNs (if desired).
Supporting security rules to control the types of traffic allowed to and from the instances in the subnets that need to communicate with the other VCN.

Though you want to resolve the issue, you want to observe the demand for a week before adding new application instances.
Which action is the most efficient way to resolve this issue?

• A.Delete the instance while preserving boot volume and spin up a new higher network bandwidth instance with this boot volume.
• B.Add a secondary virtual networkinterface card (VNIC).
• C.Change the performance tier ofattached block volume to High Performance.
• D.Change shape of the instance to a higher network bandwidth instance.
