Oracle 1Z0-997-20 Exam Dumps

A company runs a public-facing application that uses a Java-based web service via a RESTful API in their on-premises data center. Use of the API is expected to double with a new product launch. The business wants to migrate their application to Oracle Cloud Infrastructure (OCI) to meet the scale and reliability requirements. In order to achieve this, they will divert only 40% of the traffic to the new Apache Tomcat web servers running on OCI and serve the remaining 60% traffic through their on-premises infrastructure. Once the migration is complete and application works fine, they will divert all traffic to OCI. How can these requirements be met with the LEAST amount of effort?

A. Use OCI Traffic management service with failover steering policy and distribute the traffic between OCI and on premises infrastructure.

B. Use OCI Traffic management service with Load Balancing steering policy and distribute the traffic between OCI and on premises infrastructure.

C. Use an OCI load Balancer and distribute the traffic between OCI and on premises infrastructure.

D. Use VPN connectivity between on premises Infrastructure and OCI and create routing tables to distribute the traffic between them.

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 Groups' 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. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

B. You are exceeding your volume group backup quota configured.

C. 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.

D. A compute instance with multiple block volumes attached cannot move when a compartment is moved.

Your organization is planning on using Oracle Cloud Infrastructure (OCI) File Storage Service (FSS). You will be deploying multiple compute instance in Oracle Cloud Infrastructure(OCI) and mounting the file system to these compute instances.

The file system will hold payment data processed by a Database instance and utilized by compute instances to create a overall inventory report. You need to restrict access to this data for specific compute instances and must be allowed/ blocked per compute instance's CIDR block.

Which option can you use to secure access?

A. Create a new VCN security list, choose SOURCE TYPE as Service and SOURCE SERVICE as FSS. Add stateless ingress and egress rules for specific IP address and CIDR blocks.

B. Use 'Export option' feature of FSS to restrict access to the mounted file systems.

C. Create and configure OCI Web Application Firewall service with built in DNS based intelligent routing.

D. Use stateless Security List rule to restrict access from known IP addresses only.
