Oracle Cloud Infrastructure 2019 Architect Professional Sample Questions:

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 FastConnect 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 data center for each connection From yc device, advertise more specific routes via primary FastConnect virtual circuit, and less specific routes through t backup FastConnect circuit.
B. Setup FastConnect virtual circuit as your primary connection, and an IPSec VPN 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.
C. 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 less specific rod the backup IPSec VPN.
D. 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.

Question 2

An online registration system Is currently hosted on one large Oracle Cloud Infrastructure (OCT) Bare metal compute Instance with attached block volume to store of the users' data. The registration system accepts the Information from the user, Including documents and photos then performs automated verification and processing to check it the user is eligible for registration.
The registration system becomes unavailable at tunes when there is a surge of users using the system the existing architecture needs improvement as it takes a long time for the system to complete the processing and the attached block volumes are not large enough to use data being uploaded by the users.
Which Is the most effective option to achieve a highly scalable solution?

A. Upgrade your architecture to use a pool of Bare metal servers and configure them to use their local SSDs for faster data access Set up Oracle Streaming Service (OSS) to distribute the tasks to the pool of Bare metal Instances with Auto Scaling to dynamically increase or decrease the pool of compute instances depending on the length of the Streaming queue.
B. Upgrade your architecture to use more Block volumes as the data volume Increases. Replace the single bare metal instance with a group of compute instances with Auto Scaling to dynamically increase or decrease the compute instance pools depending on the traffic.
C. Change your architecture to use an OCI Object Storage standard tier bucket, replace the single bare metal instance with a Oracle Streaming Service (OSS) to ingest the Incoming requests and distribute the tasks to a group of compute Instances with Auto Scaling
D. Attach more Block volumes as the data volume increase, use Oracle Notification Service (ONS) to distribute tasks to a pool of compute instances working In parallel, and Auto Scaling to dynamically size the pool of Instances depending on the number of notifications received from the Notification Service. Use Resource Manager stacks to replicate your architecture to another region.

Question 3

You are building a highly available and fault tolerant web application deployment for your company. Similar application delayed 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 new rules based on now vulnerabilities and mitigations
B. Configure Control Rules to send traffic to multiple web servers
C. Configure multiple origin servers
D. Configure auto scaling policy and it to WAF instance.

Question 4

You have multiple IAM users who launch different types of compute Instances and block volumes every day. As a result, your Oracle cloud Infrastructure (OCF) tenancy quickly hit the service limit and you can no longer create any new instances. As you are cleaning up environment, you notice that the majority of the Instances and block volumes are untagged. Therefore, It is difficult to pinpoint the owner of these resources verify if they are safe to terminate.
Because of this, your company has issued a new mandate, which requires adding compute instances.
Which option is the simplest way to implement this new requirement?

A. Create a default tag for each compartment, which ensure that appropriate tags are applied at resource creation
B. Create tag variables to automatically tag a resource with the user name.
C. Create tag variables for each compartment to automatically tag a resource with the user name.
D. Create a policy using 1AM requiring users to tag specific resources. This will allow a user to launch compute instances on\y if certain tags were defined.
E. Create a policy to automatically tag a resource with the user name.

Question 5

You are tasked with migrating an online shopping website to Oracle Cloud Infrastructure (OCI) and decide to use a Load Balancer. You have configured the backend set with the round robin policy. During the testing phase, you noticed that users are losing items from their shopping carts when they navigate to different pages.
How should you implement a solution to this problem?

A. Set up session persistence at the Load Balancer backend set.
B. Set up a Traffic Management Steering Policy to redirect traffic to a different backend set that is deployed exclusively for the purpose of holding all Items placed in the shopping cart.
C. Configure a set of path route rules that will route to different backend sets based on the URI requested by the customer's browser.
D. Replace the round robin policy with least connections policy at the backend set.
