You have been notified of an application failure indicating that one or more of the Oracle Cloud Infrastructure (OCI) resources have become unavailable. After scanning the Compute and Database consoles, you notice that one of the DB Systems is missing.
What would you do to identify the reason for this missing resource?

1. A. Navigate to the Audit console and search the previous 24 hours for all DELETE request actions to get a list of any resource that was deleted in the past 24 hours.
2. B. Navigate to the Audit console and search the previous 24 hours for all the GET request actions to get a list of every event that occurred in the past 24 hours.
3. C. View the service limits associated with your account to ensure that you have not exceeded the allowable number of DB Systems in your tenancy.
4. D. Create a serial console connection to the DB System that does not appear in the management console.Connect to the serial console connection, and then review the system logs under /var/log/messages.

Correct Answer: A
You can filter results by request actions to zero in on only the events with operations that interest you. For example, say that you only want to know about instances that were deleted during a specific time frame. Select a delete request action filter to see only the events with delete operations

You are a network architect and have designed the network infrastructure of a three-tier application on Oracle Cloud Infrastructure (OCI). In the architecture, back-end DB servers are in a private subnet. One of your DB administrators requests to have access to OCI object storage service.
How can you meet this requirement?

1. A. Add a new route rule to the private subnet route table to route default traffic to the internet gateway.
2. B. Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway.
3. C. Create a dynamic routing gateway (DRG) and attach it to your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG.
4. D. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.

Correct Answer: D
A service gateway lets resources in your VCN privately access specific Oracle services, without exposing the data to an internet gateway or NAT. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the service of interest travels over the Oracle network fabric and never traverses the internet.
To give your VCN access to a given service CIDR label, you must enable that service CIDR label for the VCN's service gateway. You can do that when you create the service gateway, or later after it's created. You can also disable a service CIDR label for the service gateway at any time.
For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target.

A financial firm is designing an application architecture for its online trading platform that must have high availability and fault tolerance.
Their solutions architect configured the application to use an Oracle Cloud Infrastructure Object Storage bucket located in the US West (us-phoenix-1) region to store large amounts of financial data. The stored financial data in the bucket must not be affected even if there is an outage in one of the Availability Domains or a complete region.
What should the architect do to avoid any costly service disruptions and ensure data durability?

1. A. Create a new Object Storage bucket in another region and configure lifecycle policy to move data every 5 days.
2. B. Create a lifecycle policy to regularly send data from Standard to Archive storage.
3. C. Copy the Object Storage bucket to a block volume.
4. D. Create a replication policy to send data to a different bucket in another OCI region.

Correct Answer: A
