質問 1：
You have deployed a web application targeting a global audience across multiple Oracle Cloud Infrastructure (OCI) regions.
You decide to use Traffic Management Geo-Location based Steering Policy to serve web requests to users from the region closets to the user. Within each region you have deployed a public load balancer with 4 servers in a backend set. During a DR test disable all web servers in one of the regions however, traffic Management does not automatically direct all users to the other region.
Which two are possible causes?
A. One of the two working web servers In the other region did not pass Its HTTP health check
B. You did not setup a Route Table associated with load Balancer's subnet
C. You did not correctly setup the Load Balancer HTTP health check policy associated with backend set
D. Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.
E. You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region.
正解：C,E

質問 2：
You notice that a majority of your Oracle Cloud Infrastructure (OCI) resources like compute instances, block volumes, and load balancers are not tagged. You have received a mandate from your CIO to add a predefined set of tags to identify owners for respective OCI resources. E.g. if Chris and Larry each create compute instances in a compartment, the instances that Chris creates include tags that contain his name as the value, while the instances that Larry creates have his name.
Which option is the simplest way to implement this new tagging requirement?
A. Create an OCI Identity and Access Management policy requiring users to tag resources with their user name.
B. Create a default tag for each compartment, which ensure that appropriate tags are applied at the time of resource creation.
C. Create tag variables to automatically tag a resource with the user name.
D. Create an OCI Identity and Access Management policy to automatically tag a resource with the user name.
正解：C

質問 3：
You are working as a solution architect with a global automotive provider who is looking to create a multi-cloud solution. They want to run their application tier in Microsoft Azure while utilizing the Oracle DB Systems in the Oracle Cloud Infrastructure (OCI).
What is the most-fault tolerant and secure solution for this customer? (Choose the best answer.)
A. Deploy the Oracle database system into a public subnet in your VCN and assign a public IP address. Connect your application tier running in Azure to the public IP address of the database system over the internet.
B. Create an encrypted, Virtual Private Network connection between the Microsoft Azure Virtual Network that contains the application tier and the OCI Virtual Cloud Network (VCN) that contains the Oracle Databases.
C. Create a FastConnect virtual circuit with Microsoft Azure as the provider to establish a private interconnect between the application tier running in the Azure Virtual Network and the OCI VCN that contains the Oracle Databases.
D. Use an OCI Virtual Cloud Network remote peering connection to create a remote network connection between the application tier running in Microsoft Azure Virtual Network and Oracle Databases running in the OCI Virtual Cloud Network (VCN).

質問 4：
You are a solution architect working with a startup that has decided to move their workload to Oracle Cloud Infrastructure. Since their workload is small, upon architecting, you decide its sufficient to use 8 compute instances to run their workload. The company wants to use a common storage for their instances. So, you propose the idea of attaching a block volume to multiple instances to provide a common storage.
Which of the below option is NOT true for such a solution?
A. You can delete a block volume from one instance without detaching it from all other instances there by keeping other instance's storage intact.
B. Once you attach a block volume to an instance as read-only, it can only be attached to other instances as read-only.
C. If the block volume is already attached to an instance as read/write non-shareable you can't attach it to another instance until you detach it from the first instance.
D. Block volumes attached as read-only are configured as shareable by default.
正解：A

質問 5：
You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use 'Volume Groups' feature. The Block volume and Compute instances exist in different compartments within your tenancy.
Periodically, a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.
What could be the cause?
A. You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.
B. A compute instance with multiple block volumes attached cannot move when a compartment is moved.
C. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
D. You are exceeding your volume group backup quota configured.
正解：C

質問 6：
You have an application running in Microsoft Azure and want to use Oracle Autonomous Data warehouse (ADW) instance for running business analytics.
How can you build a secure solution for such a use-case?
A. Setup an interconnect between OCI and Microsoft Azure using FastConnect and ExpressRoute. Use a Service Gateway in OCI Virtual Cloud Network to provide connectivity to the Oracle ADW instance for the application in Microsoft Azure VNet.
B. Create a software Remote Peering Connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.
C. Connect the Oracle ADW in your VCN to the Microsoft Azure VNet over the internet.
D. Create a software VPN connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.
正解：A

質問 7：
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' dat a. 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. 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.
B. 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.
C. 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.
D. 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
正解：C
