A large financial services company has used 2 types of Oracle DB Systems. In Oracle Cloud Infrastructure (OCI) to store user data. One is running on a VM.Standard2.8 shape and the other on a VM.Standard 2.4 shape.
As business grows, data is growing rapidly on both the databases and performance is also degrading. The company wants to address this problem with a viable and economical solution.
As the solution architect for that company you have suggested that they move their databases to Autonomous Transaction Processing Serverless (ATP-S) database.
Which two factors should you consider before you arrived at that recommendation?
- A. Validate that ATP-S will support the storage and processing requirements for the 2 databases over the life cycle of the business applications.
- B. You verified that ATP S supports the database features and options currently being used by the 2 databases.
- C. Upon provisioning, ATP-S automatically scales up CPU to meet the application's processing requirements.
- D. Confirm that ATP-S allows customers to compress tablespaces to reduce storage costs
Answer: A,B
Explanation:
Explanation
Not all features present in Oracle Database Enterprise Edition are available in ATP, and some some Oracle Database features are restricted, for example, database features designed for administration are not available.
so you need to validate it first, You can find a complete list of the features that are not supported,
https://docs.oracle.com/en/cloud/paas/atp-cloud/atpug/experienced-database-users.html#GUID-58EE6599-6DB4 Also, you must specify the initial storage required for your database but ADB is elastic, so it is possible to grow or shrink your database as needed.
NEW QUESTION 62
You are part of a project team working in the development environment created in OCI. You have realized that the CIDR block specified for one of the subnet in a VCN is not correct and want to delete the subnet. While deleting you are getting an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet.
Which of the following action you will take to troubleshoot this issue?
- A. Use OCI CLI to call "GetVnic" operation to find out the parent resource of the VNIC
- B. Copy and Paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC
- C. Use OCI CLI to delete the VNIC first and then delete the subnet
- D. Use OCI CLI to delete the subnet using --force option
Answer: A
Explanation:
Explanation
VCN, it must first be empty and have no related resources or attached gateways To delete a VCN's subnets, they must first be empty Note: When you create one of the preceding resources, you specify a VCN and subnet for it. The relevant service creates at least one VNIC in the subnet and attaches the VNIC to the resource. The service manages the VNICs on your behalf, so they are not readily apparent to you in the Console. The VNIC enables the resource to communicate with other resources over the network. Although this documentation commonly talks about the resource itself being in the subnet, it's actually the resource's attached VNIC.
If the subnet is not empty, you instead get an error indicating that there are still resources that you must delete first. The error includes the OCID of a VNIC that is in the subnet (there could be more, but the error returns only a single VNIC's OCID).
You can use the Oracle Cloud Infrastructure command line interface (CLI) or another SDK or client to call the GetVnic operation with the VNIC OCID. The response includes the VNIC's display name. Depending on the type of parent resource, the display name can indicate which parent resource the VNIC belongs to. You can then delete that parent resource, or you can contact your administrator to determine who owns the resource.
When the VNIC's parent resource is deleted, the attached VNIC is also deleted from the subnet. If there are remaining VNICs in the subnet, repeat the process of determining and deleting each parent resource until the subnet is empty. Then you can delete the subnet.
For example, if you're using the CLI, use this command to get information about the VNIC.
oci network vnic get --vnic-id <VNIC_OCID

NEW QUESTION 71
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. You did not setup a Route Table associated with load Balancer's subnet
- B. Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.
- C. You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region.
- D. You did not correctly setup the Load Balancer HTTP health check policy associated with backend set
- E. One of the two working web servers In the other region did not pass Its HTTP health check
Answer: C,D
Explanation:
Managing Traffic Management GEOLOCATION Steering Policies
Geolocation steering policies distribute DNS traffic to different endpoints based on the location of the end user. Customers can define geographic regions composed of originating continent, countries or states/provinces (North America) and define a separate endpoint or set of endpoints for each region.
The Health Checks service allows you to monitor the health of IP addresses and hostnames, as measured from geographic vantage points of your choosing, using HTTP and ping probes. After configuring a health check, you can view the monitor's results. The results include the location from which the host was monitored, the availability of the endpoint, and the date and time the test was performed.
Also you can Combine Managing Traffic Management GEOLOCATION Steering Policies with Oracle Health Checks to fail over from one region to another The Load Balancing service provides health status indicators that use your health check policies to report on the general health of your load balancers and their components.
if you misconfigure the health check Protocol between the Load balancer and backend set that can lead to not get an accurate response as example below If you run a TCP-level health check against an HTTP service, you might not get an accurate response. The TCP handshake can succeed and indicate that the service is up even when the HTTP service is ly configured or having other issues. Although the health check appears good customers might experience transaction failures.
NEW QUESTION 72
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 policy using IAM requiring users to tag specific resources. This will allow a user to launch compute instances on\y if certain tags were defined.
- B. Create a default tag for each compartment, which ensure that appropriate tags are applied at resource creation
- C. Create a policy to automatically tag a resource with the user name.
- D. Create tag variables to automatically tag a resource with the user name.
- E. Create tag variables for each compartment to automatically tag a resource with the user name.
Answer: D
Explanation:
Tag Variables
You can use a variable to set the value of a defined tag. When you add the tag to a resource, the variable resolves to the data it represents. You can use tag variables in defined tags and default tags.
Supported Tag Variables
The following tag variables are supported.
${iam.principal.name} The name of the principal that tagged the resource
${iam.principal.type} The type of principal that tagged the resource.
${oci.datetime} The date and time that the tag was created.
Consider the following example:
Operations.CostCenter=" ${iam.principal.name} at ${oci.datetime} "
Operations is the namespace, CostCenter is the tag key, and the tag value contains two tag variables ${iam.principal.name} and ${oci.datetime} . When you add this tag to a resource, the variable resolves to your user name (the name of the principal that applied the tag) and a time date stamp for when you added the tag.
user_name at 2019-06-18T18:00:57.604Z
The variable is replaced with data at the time you apply the tag. If you later edit the tag, the variable is gone and only the data remains. You can edit the tag value in all the ways you would edit any other tag value. To create a tag variable, you must use a specific format.
${<variable>} Type a dollar sign followed by open and close curly brackets. The tag variable goes between the curly brackets. You can use tag variables with other tag variables and with string values. Tag defaults let you specify tags to be applied automatically to all resources, at the time of creation, in a specific compartment. This feature allows you to ensure that appropriate tags are applied at resource creation without requiring the user who is creating the resource to have access to the tag namespaces.

- E. Contiguous numbers need to be assigned for each part so that Object Storage constructs the object by ordering, part numbers in ascending order
Answer: A,D
Explanation:
You can check on an active multipart upload by listing all parts that have been uploaded. (You cannot list information for an individual object part in an active multipart upload.) After you finish creating object parts, initiate a multipart upload by making a CreateMultipartUpload REST API call. Provide the object name and any object metadata. Object Storage responds with a unique upload ID that you must include in any requests related to this multipart upload. Object Storage also marks the upload as active. The upload remains active until you explicitly commit it or abort it.

Which option should you recommend to provide the highest level of redundancy?
- A. Set up a single IPSec VPN connection (rom your data center to Oracle Cloud Infrastructure since It is cost effective
- B. Set up both IPSec VPN and FastConnect to connect your on premises data centers to Oracle Cloud Infrastructure.
- C. If your data centers span multiple, geographical locations, use only the specific IP address as a static route for the specific geographical location
- D. Use FastConnect private peering only to ensure secure access from your data center to Oracle Cloud Infrastructure
- E. Oracle cloud Infrastructure provides network redundancy by default so that no other operations are required
Answer: C
Explanation:
If your data centers span multiple geographical locations, we recommend using a broad CIDR (0.0.0.0/0) as a static route in addition to the CIDR of the specific geographical location. This broad CIDR provides high availability and flexibility to your network design. For instance, the following diagram shows two networks in separate geographical areas that each connect to Oracle Cloud Infrastructure. Each area has a single on-premises router, so two IPSec VPN connections can be created. Note that each IPSec VPN connection has two static routes: one for the CIDR of the particular geographical area, and a broad 0.0.0.0/0 static route.

Which option should you consider while designing your Data Guard configuration to ensure best RTO and PRO without causing any data loss?
- A. Configure ''Maximum Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in SYNC mode between two regions.
- B. Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.
- C. Configure "Maximum Protection" mode which provides zero data loss If the primary database fails.
- D. Configure "Maximum Performance" mode In SYNC mode between two availability domains (same region) which provides, the highest level of data protection that is possible without affecting the performance of the primary database.
Answer: A
Explanation:
Explanation
https://docs.cloud.oracle.com/en-us/iaas/Content/Resources/Assets/whitepapers/best-practices-for-dr-on-oci.pdf All three Data Guard configurations are fully supported on Oracle Cloud Infrastructure. However, because of a high risk of production outage, we don't recommend using the maximum protection mode for your Data Guard configuration.
We recommend using the maximum availability mode in SYNC mode between two availability domains (same region), and using the maximum availability mode in ASYNC mode between two regions. This architecture provides you the best RTO and RPO without causing any data loss. We recommend building this architecture in daisy-chain mode: the primary database ships redo logs to the first standby database in another availability domain in SYNC mode, and then the first standby database ships the redo logs to another region in ASYNC mode. This method ensures that your primary database is not doing the double work of shipping redo logs, which can cause performance impact on a production workload.
This configuration offers the following benefits:
* No data loss within a region.
* No overhead on the production database to maintain standbys in another region.
* Option to configure lagging on the DR site if needed for business reasons.
* Option to configure multiple standbys in different regions without any additional overhead on the
* production database. A typical use case is a CDN application
