NEW QUESTION 55
A customer is in a process of shifting their web based Sales application from their own data center located in US West to OCI India West (Mumbai) region. They want to do it in a controlled manner and initially only 1% of the traffic will be steered to the servers in OCI. After verification of everything is working as expected, the company is gradually planning to increase the ratio until they are comfortable with fully migrating all traffic to OCI.
Which of the following solution can be used in this situation?
- A. OCI DNS and OCI Load Balancer Service
- B. OCI DNS and Traffic Management with Geolocation Steering policy
- C. OCI DNS and Traffic Management with Failover Steering policy
- D. OCI DNS and Traffic Management with Load Balancer Steering policy
Answer: B
Explanation:
STEERING POLICIES is A framework to define the traffic management behavior for your zones. Steering policies contain rules that help to intelligently serve DNS answers.
FAILOVER
Failover policies allow you to prioritize the order in which you want answers served in a policy (for example, Primary and Secondary). Oracle Cloud Infrastructure Health Checks are leveraged to determine the health of answers in the policy. If the Primary Answer is determined to be unhealthy, DNS traffic will automatically be steered to the Secondary Answer.
LOAD_BALANCE
Load Balancer policies allow distribution of traffic across multiple endpoints. Endpoints can be assigned equal weights to distribute traffic evenly across the endpoints or custom weights may be assigned for ratio load balancing. Oracle Cloud Infrastructure Health Checks are leveraged to determine the health of the endpoint. DNS traffic will be automatically distributed to the other endpoints, if an endpoint is determined to be unhealthy.
ROUTE_BY_GEO
Geolocation-based 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.
ROUTE_BY_ASN
ASN-based steering policies enable you to steer DNS traffic based on Autonomous System Numbers (ASN).
DNS queries originating from a specific ASN or set of ASNs can be steered to a specified endpoint.
ROUTE_BY_IP
IP Prefix-based steering policies enable customers to steer DNS traffic based on the IP Prefix of the originating query.

NEW QUESTION 60
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 Group's 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. Compute instance with multiple block volumes attached cannot move when a compartment is moved.
- C. You are exceeding your volume group backup quota configured.
- D. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
Answer: D
Explanation:
You can move a compartment to a different parent compartment within the same tenancy. When you move a compartment, all its contents (subcompartments and resources) are moved with it. Moving a compartment has implications for the contents.
After you move a compartment to a new parent compartment, the access policies of the new parent take effect and the policies of the previous parent no longer apply. Before you move a compartment, ensure that:
You are aware of the policies that govern access to the compartment in its current position.
You are aware of the polices in the new parent compartment that will take effect when you move the compartment.
In some cases, when moving nested compartments with policies that specify the hierarchy, the polices are automatically updated to ensure consistency.

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. You did not correctly setup the Load Balancer HTTP health check policy associated with backend set
- C. One of the two working web servers In the other region did not pass Its HTTP health check
- 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.
Answer: B,E
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.

You have provisioned a new VM.DenseIO2.24 compute instance with local NVMe drives. The compute instance is running production application. This is a write heavy application, with a significant Impact to the business it the application goes down.
What should you do to help maintain write performance and protect against NVMe devices failure.
- A. NVMe drive have built in capability to recover themself so no other actions are required
- B. Configure RAID 10 for NVMe devices.
- C. Configure RAID 6 for NVMe devices.
- D. Configure RAID 1 for NVMe devices.
Answer: B
Explanation:
VM.DeselO2.24 compute instance include locally attached NVMe devices. These devices provide extremely low latency, high performance block storage that is ideal for big data, OLTP, and any other workload that can benefit from high-performance block storage.
A protected RAID array is the most recommended way to protect against an NVMe device failure. There are three RAID levels that can be used for the majority of workloads:
RAID 1: An exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks RAID 10: Stripes data across multiple mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved RAID 6: Block-level striping with two parity blocks distributed across all member disks If you need the best possible performance and can sacrifice some of your available space, then RAID 10 array is an option.

NEW QUESTION 68
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 for each compartment to automatically tag a resource with the user name.
- C. Create tag variables to automatically tag a resource with the user name.
- D. Create a policy to automatically tag a resource with the user name.
- E. 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.
Answer: C
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.

In compliance with the Business Continuity Program of the client, they need to provide a Recovery Point objective (RPO) of 24 hours and a Recovery time objective (RTO) of 24 hours and Recovery Time Objective (RTO) of 1 hour.
The CRM application should be available oven in me event that an entire on Region is down.
Which approach Is the most suitable and cost effective configuration for this scenario?
- A. Deploy a 1 node VM Oracle database in one region. Manual Configure a Recovery Manager (RMAN) database backup schedule to take hourly database backups. Asynchronously copy the database backups to object storage in another OCI region, If the primary OCI region is unavailable launch a new 1 new VM Database in the other OCI region restore the production database from the backup.
- B. Deploy an Autonomous Transaction Processing (Serverless) database in one region and replicate it to an Autonomous Transaction Processing (Serverless) database in another region Oracle GoldenGate.
- C. Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.
- D. Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard.
Answer: C
Explanation:
You can configure the Autonomous Database instance as a target database for Oracle GoldenGate. But You can't set up Oracle Autonomous Database as a source database for Oracle GoldenGate.
Recovery Point objective (RPO) of 24 hours and Recovery Time Objective (RTO) of 1 hour
- To provision new VM and restore the production database from the backup on object storage, will exceed the RTO 1 hour
- You can create the standby DB system in a different availability domain from the primary DB system for availability and disaster recovery purposes. With Data Guard and switchover/failover can meet RTO
1 hour.
- RAC Database is not required in this solution. Standalone will be most suitable and cost effective

Explanation:
Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.
The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution.
You can create automation based on state changes for your Oracle Cloud Infrastructure resources by using event types, rules, and actions. When the function is executing inside the container, the function can read from and write to other resources and services running in the same subnet (for example, Database as a Service). The function can also read from and write to other shared resources (for example, Object Storage), and other Oracle Cloud Services.
