Question 1
- You are creating an Oracle CloudInfrastructure Dynamic Group. To determine the members of this group you
  are defining a set of matching rules.
  Which of the following are the supported variables to define conditions in the matching rules? (Choose Two)
  
  A : iam.policy.id - the OCID of the IAM policy to apply to the group.
  
  B : instance.tenancy.id - the OCID of the tenancy where the instance resides.
  
  C : tag.< tagnamespace >.< tagkey >.value - the tag namespace and tag key
  
  D : instance.compartment.id - the OCID of the compartment where the instanceresides.
  
  Answer: C,D
Question 2
- You are building a highly available and fault tolerant web application deployment for your company. Similar
  applicationdelayed by competitors experienced web site attack including DDoS which resulted in web server
  failing.
  You have decided to use Oracle Web Application Firewall (WAF) to implement an architecture which will
  provide protection against such attacks and ensure additional configuration will you need to implement to
  make sure WAF is protecting my web application 24×7.
  Which additional configuration will you need to Implement to make sure WAF Is protecting my web
  application 24×7?
  
  A : Configure auto scaling policy and it to WAF instance.
  
  B : Configure Control Rules to send traffic to multiple web servers
  
  C : Configure multiple origin servers
  
  D : Configure new rules based on now vulnerabilities and mitigations
  
  Answer: C
Question 3
- You are responsible for migrating your on-premises legacy databases on 11.2.0.4 version to Autonomous
  Transaction Processing - Dedicated (ATP-D) in OracleCloud Infrastructure (OCI). As a solution architect, you
  need to plan your migration approach.
  Which three options do you need to implement together to migrate your on-premises databases to OCI?
  
  A : Retain all legacy structures and unsupported features (e.g. legacy LOBs) in the on-premises databases for migration
  
  B : Use Oracle Data Guard to keep on-premises database always active during migration.
  
  C : Launch Autonomous Transaction Processing - Dedicated database in OCI.
  
  D : Retain changes to Oracle shipped privileges, stored procedures or views in the on-premises databases.
  
  E : Convert on-premises databases to PDB, upgrade to 19c, and encrypt.
  
  F : Use Oracle GoldenGate replication to keep on-premises database online during migration.
  
  Answer: A,C
Question 4
- 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 5
- 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
