Question 1
- A retail company has recently adopted a hybrid architecture. They have the following requirements for their
  end-to-end Connectivity model between their on-premises data center and Oracle Cloud Infrastructure (OC1)
  region
  *Highly available connection with service level redundancy
  * Dedicated network bandwidth with low latency
  Which connectivity setup is the most cost effective solution for this scenario?
  
  A :
  Setup IPsec VPN as your primary connection, and a FastConnect virtual circuit as a backup connection. Use separate edge devices in your on-premises data canter for each connection from your edge devices, advertise more specific routes IPSec VPN, and specific routes through the backup FastConnect virtual circuit
  
  B :
  SetupFastConnect virtual circuit as your primary connection, and a second FastConnect virtual circuit as a backup connection. Use separate edge devices in your FastConnect physical connectivity is redundant Use a single edge device in your on premises datacenter for each connection From yc device, advertise more specific routes via primary FastConnect virtual circuit, and less specific routes through t backup FastConnect circuit
  
  C :
  Setup FastConnect virtual circuit as your primary connection, and an IPSecVPN as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes through FastConnect virtual circuit, and more specific routes through the backup IPSec VPN path.
  
  D :
  Setup IPSec VPN as your primary connection, and a second IPSec VPN as a backup connection. Use separate edge devices in your on p data center for each connection. From your edge devices, advertise more specific routes via primary IPSec VPN. and lessspecific rod the backup IPSec VPN.
  
  Answer: D
Question 2
- A large financialcompany has a web application hosted in their on-premises data center. They are migrating
  their application to Oracle Cloud Infrastructure (OCI) and require no downtime while the migration is
  on-going. In order to achieve this, they have decided to divertonly 30% of the application works fine, they
  divert all traffic to OCI.
  As a solution architect working with this customer, which suggestion should you provide them?
  
  A : Use OCI Traffic management with failover steering policy and distribute the trafficbetween OC1 and on premises infrastructure.
  
  B : Use OCI Traffic management 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
  
  Answer: B
Question 3
- 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
Question 4
- You have been asked to create a mobile application which will be used for submitting orders by users of a
  popular E-Commerce site. The application is built to work with Autonomous Transaction Processing -
  Serverless (ATP-S) databaseas the backend and HTML5 on Oracle Application Express as the front end.
  During the peak usage of the application you notice that the application response time is very slow. ATP-S
  database is deployed with 3 CPU cores and 1 TB of memory.
  Which two optionsare expensive or impractical ways to improve the application response times?
  
  A : Identify the maximum memory capacity needed for peak times and scale the memory for the ATP-S database to that number. ATP-S will scale the memory down when not needed.
  
  B : Usethe Machine Learning (ML) feature of the ATP-S database iteratively to tune the SQL queries used by the application
  
  C : Scale up CPU core count and memory during peak times.
  
  D : Enable auto scaling for CPU cores on ATP-S database.
  
  E : Identify the maximum CPU capacity needed for peak times and scale the CPU core count for the ATP-S database to that number. ATP-S will scale the CPU core count down when not needed.
  
  Answer: A,C
Question 5
- As a solution architect, you are designing a web application to be deployed across multiple Oracle Cloud Infrastructures (OCI) regions for a global audience. Your goal is that users from each region should access the application web servers deployed in their own geographical OCI location. Which OCI feature can be used to achieve this?
  A : OCI Traffic Management IP Prefix steering policy
  
  B : OCI Global Load balancers
  
  C : OCI Public Load Balancers
  
  D : OCI Traffic Management GeoLocation steering policy
