QUESTION NO: 2
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 dynamic routing gateway (DRG) with the VCN in each region and configure an IPsec VPN connection between the two regions.
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 DRG with the VCN in each region and create a remote peering connection between the two VCNs.
Answer: D
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 remote peering 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.
QUESTION NO: 3
You need to transfer over 12 TB of data from on-premises to your cloud account. You started copying this data over the internet and noticed that it will take too long to complete.

A. Split the data into multiple parts and use the multipart tool.
B. Use a 10 GB FastConnect line to send the data.
C. Compress the data and use the multipart tool.
D. Use Data Transfer Service to send your data.
E. Send the data over a VPN IPsec tunnel.
Answer: D
