Free Oracle 1Z0-997-25 Exam Questions

Question 1

You have been asked to implement a bespoke financial application in Oracle Cloud Infrastructure using virtual

machine instances controlled by Autoscaling across multiple Availability Domains. The application stores

transaction logs, intermediate transaction data, and audit data and needs to store this on a persistent, durable

data store accessible from all of the application servers. The application requires the file system to be mounted

in the /audit folder on the

Linux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintain

data integrity. The solution should be as low maintenance as possible.

What storage architecture should you suggest?

A : Use locally attached NVMe instances andconfigure RAID 0 replication between servers.

B : Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances.

C : Store the data on Oracle Object Storage mounted at the/audit mount point on all the Linux instances using the default mount options.

D : Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.

Answer: D

Question 2

You are working as a solution architect for an online retail store to create a portal to allow the users to pay for

their groceries using credit cards. Since the application is not fully compliantwith the Payment Card Industry

Data Security Standard (PCI DSS), your company is looking to use a third party payment service to process

credit card payments.

The third party service allows a maximum of Spelunk IP addresses 5 public IP addresses at a timeHowever,

your website is using Oracle Cloud Infrastructure (OCI) Instance Pool Auto Scaling policy to create up to

create up to 15 Instances during peak traffic demand, which are launched In VCN private in VCN private

subnets and attached to an OCI public Load Balancer. Upon user payment, the portal connects to the payment

service over the Interne! to complete the transaction

What solution can you implement to make sure that all compute Instances can connect to the third party

system to process the payments aw peak traffic demand?

A : Route credit card payment request from the compute instances through the NAT Gateway. On the third-party services, whitelist the public IP associated with the NAT Gateway

B : Create an OCI Command Line Interface (CLI) scriptto automatically reserve public IP address for the compute instances. On the third-party services, whitelist the Reserved public IP

C : Whitelist the Internet Gateway Public IP on the third party service and route all payment requests through the InternetGateway

D : Route payment request from the compute instances through the OCI Load Balancer, which will then be routed to the third party service

Answer: A

Question 3

A data analytics company has been building Its now generation big data and analytics platform on Oracle

Cloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their big

data applications require such as high throughput to compute nodes with low latency file operations in

addition, their data needs to be stored redundantly across multiple nodes In a single availability domain and

allows concurrent connections from multiple compute Instances hosted on multiple availability domains.

Which OCI storage service can you use to meet i his requirement?

A : Object Storage

B : File System Storage

C : Archive storage

D : Block Volume

Answer: B

Question 4

You are responsible formigrating your on premises legacy databases on 11.2.0.4 version to Autonomous Transaction Processing Dedicated (ATP-D) In Oracle Cloud Infrastructure (OCI). As a solution architect, you need to plan your migration approach. Which two options do you needto implement together to migrate your on premises databases to OCI?

A : Use Oracle Data Guard to keep on premises database always active during migration

B : Retain changes to Oracle shipped privileges, stored procedures or views In the on-premises databases.

C : Use Oracle GoldenGate replication to keep on premises database online during migration.

D : Convert on-premises databases to PDB, upgrade to 19c, and encrypt Migration.

E : Retain all legacy structures and unsupported features (e.g. taw U>Bs) In the onuses databases for migration.

Answer: C,D

Question 5

A retailer bank is currently hosting their mission critical customer application on-premises. The application

has a standard 3 tier architecture -4 application servers process the incoming traffic and store application data

in an Oracle Exadata Database Server. The bank has recently has service disruption to other inter applications

to they are looking to avoid this issue for their mission critical Customer Application.

Which Oracle Cloud Infrastructure services should you recommend as part of the DR solution?

A : OCI DNS Service' Public Load Balancer, Oracle Database Cloud Backup Service, ObjectStorage Service, Oracle Bare Metal Cloud Service, Oracle Bare Metal Cloud Service with GoldenGate, OCI Container Engines for Kubernetes, Oracle IPSec VPN

B : OCI Traffic Management, Private Load Balancer, Compute instances distributed across multiple Availability Domains and/or Fault Domains, Exadata Cloud Service with Data Guard, Oracle FastConnect, Object Storage, Database Cloud backup module

C : OCI Traffic Management, Public toad Balancer, Compute Instances distributed across multiple Availability Domains and/or Vault domains. Exadata Cloud Service with Data Guard, Oracle FastConnect, Object Storage, Database cloud backup module

D : OCI DNS Service, Load Balancer as a service using Public Load Balancer distributing traffic Compute Instance across multiple regions, Oracle RAC Database using Virtual Machines, Remote Peering connecting two VCNs in different regions. Exadata Cloud Service with GoldenGate FastConnect, Object Storage, Database Cloud backup module.

Answer: C
