Oracle offers offline data transfer solutions that let you migrate data to Oracle Cloud Infrastructure. You have 2 Options of Data Transfer
DISK-BASED DATA TRANSFER
You send your data as files on encrypted commodity disk to an Oracle transfer site. Operators at the Oracle transfer site upload the files into your designated Object Storage bucket in your tenancy.
APPLIANCE-BASED DATA TRANSFER
you send your data as files on secure, high-capacity, Oracle-supplied storage appliances to an Oracle transfer site. Operators at the Oracle transfer site upload the data into your designated Object Storage bucket in your tenancy.

NEW QUESTION 2
All three Data Guard Configuration are fully supported on Oracle Cloud infrastructure (OCI). You want to deploy a maximum availability architecture (MAA) for database workload.
Which option should you consider while designing your Data Guard configuration to ensure best RTO and PRO without causing any data loss?

• A. Configure "Maximum Protection" mode which provides zero data loss If the primary database fails.
• B. Configure "Maximum Performance" mode In SYNC mode between two availability domains (same region) which provides, the highest level of data protection that is possible without affecting the performance of the primary database.
• C. Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.
• D. Configure ''Maximum Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in SYNC mode between two regions.

Answer: D

Explanation:
https://docs.cloud.oracle.com/en-us/iaas/Content/Resources/Assets/whitepapers/best-practices-for-dr-on-oci.pdf All three Data Guard configurations are fully supported on Oracle Cloud Infrastructure. However, because of a high risk of production outage, we don’t recommend using the maximum protection mode for your Data Guard configuration.
We recommend using the maximum availability mode in SYNC mode between two availability domains (same region), and using the maximum availability mode in ASYNC mode between two regions. This architecture provides you the best RTO and RPO without causing any data loss. We recommend building this architecture in daisy-chain mode: the primary database ships redo logs to the first standby database in another availability domain in SYNC mode, and then the first standby database ships the redo logs to another region in ASYNC mode. This method ensures that your primary database is not doing the double
work of shipping redo logs, which can cause performance impact on a production workload.

This configuration offers the following benefits:
No data loss within a region.
No overhead on the production database to maintain standbys in another region.
Option to configure lagging on the DR site if needed for business reasons.
Option to configure multiple standbys in different regions without any additional overhead on the
production database. A typical use case is a CDN application

NEW QUESTION 5
You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use Volume Group's feature. The Block volume and Compute instances exist in different compartments within your tenancy.
Periodically. a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.
What could be the cause?

• A. You are exceeding your volume group backup quota configured.
• B. You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.
• C. Compute instance with multiple block volumes attached cannot move when a compartment is moved.
• D. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

Answer: D

Explanation:
You can move a compartment to a different parent compartment within the same tenancy. When you move a compartment, all its contents (subcompartments and resources) are moved with it. Moving a compartment has implications for the contents.
After you move a compartment to a new parent compartment, the access policies of the new parent take effect and the policies of the previous parent no longer apply. Before you move a compartment, ensure that:
You are aware of the policies that govern access to the compartment in its current position.
You are aware of the polices in the new parent compartment that will take effect when you move the compartment.
In some cases, when moving nested compartments with policies that specify the hierarchy, the polices are automatically updated to ensure consistency.

Answer: D

Explanation:
Moving Resources to a Different Compartment
Most resources can be moved after they are created. There are a few resources that you can't move from one compartment to another. Some resources have attached resource dependencies and some don’t.
Not all attached dependencies behave the same way when the parent resource moves.
For some resources, the attached dependencies move with the parent resource to the new compartment.
The parent resource moves immediately, but in some cases attached dependencies move asynchronously and are not visible in the new compartment until the move is complete.
For other resources, the attached resource dependencies do not move to the new compartment. You can move these attached resources independently.
You can move Compute resources such as instances, instance pools, and custom images from one compartment to another. When you move a Compute resource to a new compartment, associated resources such as boot volumes and VNICs are not moved.
You can move a VCN from one compartment to another. When you move a VCN, its associated VNICs, private IPs, and ephemeral IPs move with it to the new compartment.

NEW QUESTION 15
You have designed and deployed your Autonomous Data Warehouse (ADW) such that it is accessible from your on-premises data center and servers running on both private and public networks in Oracle Cloud Infrastructure (OCI).

As you are testing the connectivity to your ADW database from the different access paths, you notice that the server running on the private network is unable to connect to ADW.
Which two steps do you need to take to enable connectivity from the server on the private network to ADW? (Choose two.)

• A. Add an entry in the Security List of the ADW allowing ingress traffic for C10R block 10.2.2.0/24
• B. Add an entry in the route table (associated with the private subnet) with destination of 0.0.0.0/: target type of NAT Gateway, add a stateful egress rule to the security list (associated with the private subnet) with destination of 0.0.0.0./0 and for all IP protocols.
• C. Add an entry in the access table list of ASW for CIDR block 10.2.2.0/24.
• D. Add an entry in the route table (associated with the private subnet) with destination of 0.0.0.0./0; target type of internet Gateway, add a stateful egress in the security list (associated with the private subnet) with destination of 0.0.0.0/0 and for all IP protocols.
