Question 1
- An Oracle Cloud Infrastructure (OCI) PublicLoad Balancer's SSL certificate is expiring soon. You noticed the Load Balancer is configured with SSL Termination only. When the certificate expires, data traffic can be interrupted and security compromised. What steps do you need to take to prevent thissituation?
  A : Add the new SSL certificate to the Load Balancer, update backend servers to work with a new certificate and edit listeners so they can use the new certificate bundle
  
  B : Add the new SSL certificate to the Load Balancer, update listeners andbackend sets so they can use the new certificate bundle.
  
  C : Add the new SSL certificate to the Load Balancer and implement end to end SSL so it can encrypt the traffic from clients all the way to the backend servers.
  
  D : Add the new SSL certificate to the Load Balancer and update backend servers to use the new certificate bundle.
  
  E : Add the new SSL certificate to the Load Balancer and update listeners to use the new certificate bundle.
  
  Answer: A
Question 2
- 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 3
- 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 4
- You are tasked with building a highly available, fault tolerant web application for your current employer. The
  security team is concernedabout an increase in malicious web-based attacks across the internet and asked what
  you can do to add a higher level of security to the website.
  How should you architect the solution on Oracle Cloud Infrastructure (OCI) to meet all requirements defined
  byyour organization? (Choose the best answer.)
  
  A : Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of theweb application servers. Deploy a Web Application Firewall (WAF) and configure the load balancer public IP address as the origin.
  
  B : Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Create a Geolocation steering policy in Traffic Management and add an answer pool that directs to the public IP address of the load balancer. Configure a global catch-all rule to use this answer pool.
  
  C : Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Ensure that each web application server is assigned a public IP address. Deploy a Web Application Firewall (WAF) and configure one Origin for each public IP address.
  
  D : Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Use the OCI Traffic Management service to create a load balancing policy that will resolve DNS evenly between all web servers.
  
  Answer: A
Question 5
- You are creating an Oracle Cloud Infrastructure Dynamic Group. To determine the members of thisgroup 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 : instance.compartment.id -the OCID of the compartment where the instance resides.
  
  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 : iam.policy.id - the OCID of the IAM policy to apply to the group.
  
  Answer: A,C
