You are deploying a highly available web application in Oracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs).

How many subnets should you create to deliver a secure highly available application?

• three subnets in total; one subnet in each AD

• five subnets in total; two subnets each in the first and second AD with a single subnet in the third AD

• six subnets in total; two subnets in each AD; one for the load balancer and one for the web servers

• four subnets in total; one subnet in each AD for the web servers and a single subnet in any one AD for the load balancer

You have just created an Autonomous Data Warehouse (ADW) and you want to connect to the ADW using SQL Developer.

What three items are needed to connect to the ADW using SQL Developer? (Choose three.)

• the keystore password

• a security list with an ingress rule for TCP port 1521

• the client credentials file

• the public IP address of the ADW server

• the admin password

You are planning to deploy a multi-region web application in Oracle Cloud Infrastructure (OCI). You have customers in North America, Asia and Europe who will access the application.

What service is available in OCI to help you choose the regions the lowest latency to these markets?

• Internet Intelligence

• FastConnect

• IPsec VPN

• DNS Zone Management

Which two options are valid for loading data directly into Autonomous Data Warehouse (ADW)? (Choose two.)

• Data Integrator

• Data Pump

• Data Transfer Service

• SQL *Loader

Where do you find the tnsnames.ora for your Autonomous Data Warehouse (ADW) database?

• You can download tnsnames.ora from Oracle Cloud Infrastructure web console under ADW details page

• The tnsnames.ora file is included in credentials.zip file that you download from service console of ADW

• The ADW database will place the tnsnames.ora file in an object storage bucket

• You are automatically prompted to download the tnsnames.ora file upon creation of the ADW database

A customer has established an Oracle Cloud Infrastructure (OCI) FastConnect connection to OCI. The virtual circuit is up and routes are being advertised from the customer’s end, however the customer is unable to ping from compute instances inside the virtual cloud network (VCN) to servers residing in its on-premises data center.

Which two options on OCI would remedy this situation? (Choose two.)

• Modify the route table associated with the VCN subnet in which the instance resides. Add a route to the customer’s on-premises network via the Dynamic Routing Gateway (DRG).

• Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow ICMP traffic to the customer’s on-premises network

• Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful ingress rule to allow ICMP traffic from anywhere.

• Modify the default VCN route table to add a route back to the customer’s on-premises network via the DRG.

Which service would you use if your big data workload required shared access and NFS-based connectivity?

• block volume

• archive storage

• object storage

• file storage

our company is developing a new database application in Oracle Cloud Infrastructure. You need to test application functionality including a hardware failure scenario. Since the application is still in the development phase, you want to minimize infrastructure costs.

Which database service deployment option meets this requirement?

• two node real application cluster (RAC) system

• Autonomous Data Warehouse (ADW) system as it provides auto fail over functionality

• two node bare metal system with data guard enabled

• single node bare metal system

Your on-premises hosted application uses Oracle database server. Your database administrator must have access to the database server for managing the application. Your database server is sized for seasonal peak workloads, which results in high licensing costs. You want to move your application to Oracle Cloud Infrastructure (OCI) to take advantage of CPU scaling options.

Which database offering on OCI would you select?

• bare metal DB systems

• VM DB systems

• Autonomous Transactions Processing (ATP)

• Autonomous Data Warehouse (ADW)

You have an application running on Oracle Cloud Infrastructure. You identified that the read and write operations are slowing your application down enough to impair user access. The application is currently using a VM.Standard 1.2 compute without any block storage attached to it.

Which two options allow you to increase disk performance? (Choose two.)

• Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.

• Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.

• Create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.

• Terminate the compute instance and create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup
