質問 2：
A company has an urgent requirement to migrate 300 TB of data to Oracle Cloud Infrastructure (OCI) In two weeks. Their data center has been recently struck by a massive hurricane and the building has been badly damaged, although still operational. They have a 100 Mbps Internet line but the connection is Intermittent due to the damages caused to the electrical grid in this scenario, what is the most effective service to use to migrate the data to OCI given the time constraints?
A. Use multiple OCI Data Transfer Appliances to transfer data to OCI.
B. Upload the data to OCI using OCI Object Storage multipart upload tool.
C. Setup a OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI using OCI Storage Gateway Cloud Sync tool.
D. Setup a hybrid network by launching aIGbpsFastConnect virtual circuit between your data center and OCI. Use OCI Object storage multipart upload tool to automate the migration of your data to OCI.
E. Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI.

質問 3：
You have provisioned a new VM.DenseIO2.24 compute instance with local NVMe drives. The compute instance is running production application. This is a write heavy application, with a significant Impact to the business it the application goes down.
What should you do to help maintain write performance and protect against NVMe devices failure.
A. Configure RAID 6 for NVMe devices.
B. NVMe drive have built in capability to recover themself so no other actions are required
C. Configure RAID 10 for NVMe devices.
D. Configure RAID 1 for NVMe devices.

質問 4：
A large London based eCommerce company is running Oracle DB System Virtual RAC database on Oracle Cloud Infrastructure (OCI) for their eCommerce application activity. They are launching a new product soon, which is expected to sell in large quantities all over the world.
The application architecture should have minimal cost, no data loss, no performance impacts during the database backup windows and should have minimal downtime.
A. Turn off automatic backups from the eCommerce database, implement Oracle Active Data Guard with the standby database deployed on another availability domain, and take backups from the standby database.
B. Launch a new VM RAC database in another availability domain, launch a compute instance, deploy Oracle GoldenGate on it and then configure it to replicate the data from the eCommerce Database over to the new RAC database using GoldenGate. Take backups from the new VM RAC database.
C. Turn off automated backups from the eCommerce database, implement Oracle Data Guard with the Standby database deployed on another availability domain, take backups from the standby database.
D. Launch a new VM RAC database in another availability domain, launch a compute instance, deploy Oracle GoldenGate on it and then configure bi-directional replication from the eCommerce Database over to the new VM RAC database using GoldenGate. Take backups from the new VM RAC database.

質問 5：
You are tasked with migrating an online shopping website to Oracle Cloud Infrastructure (OCI) and decide to use a Load Balancer. You have configured the backend set with the round robin policy. During the testing phase, you noticed that users are losing items from their shopping carts when they navigate to different pages.
How should you implement a solution to this problem?
A. Replace the round robin policy with least connections policy at the backend set.
B. Configure a set of path route rules that will route to different backend sets based on the URI requested by the customer's browser.
C. Set up session persistence at the Load Balancer backend set.
D. Set up a Traffic Management Steering Policy to redirect traffic to a different backend set that is deployed exclusively for the purpose of holding all Items placed in the shopping cart.
正解：A

質問 6：
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 sewer lunninq 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?
A. 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.
B. Add an entry in the access control list of ADW for IP address 129.146.160.11
C. 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.
D. Add an entry in the Security List of the ADW allowing ingress traffic for C10R block 10.2.2.0/24
E. Add an entry in the access table list of ASW for CIDR block 10.2.2.0/24.

質問 7：
You are working with a customer who needs to attach an Oracle Cloud Infrastructure (OCI) block volume to a VM instance with read/write access type. The customer wants to know if the number of IOPS and throughput performance differs between the following two choices:
* Option A: attach a single 1 TB block volume to the VM instance
* Option B: attach two separate 500 GB block volumes In a RAID 0 array configuration to the VM instance You can assume that the customer is using iSCSI attachment type to attach the volumes to the instance. In addition, you can assume 1 MB block size for throughput and 4 KB block size for IOPS consideration.
How should you respond to the customer?
A. Both options provide the same number of IOPS and throughput performance.
B. Option A provides better IOPS, but lower throughput performance.
C. Option B provides higher level of throughput, but lower level of IOPS performance.
D. Option B provides better IOPS and throughput performance.
正解：A
