  Correct Answer: B

  A 503 Service Unavailable Error is an HTTP response status code indicating that a server is temporarily unable to handle the request. This may be due to the server being overloaded or down for maintenance.

• Question 22:

  You are currently working for a public health care company based in the United Stats. Their existing patient records runs in an on-premises data center and the customer is sending tape backups offsite as part of their recovery planning.

  You have developed an alternative archival solution using Oracle Cloud Infrastructure (OCI) that will save the company a significant amount of mom on a yearly basis. The solution involves storing data in an OCI Object Storage bucket After reviewing your solution with the customer global Compliance (GRC) team they have highlighted the following security requirements:

  All data less than 1 year old must be accessible within 2 hour. All data must be retained for at least 10 years and be accessible within 48 hours AH data must be encrypted at rest No data may be transmitted across the public Internet

  Which two options meet the requirements outlined by the customer GRC team?

  A. Provision a FastConnect link to the closest OCI region and configure a private peering virtual circuit.

  B. Create an OCI Object Storage Standard tier bucket Configure a lifecycle policy to archive any object that Is older than 365 days

  C. Create a VPN connection between your on premises data center and OCI. Create a Virtual Cloud Network (VCN) along with an OCI Service Gateway for OCI Object Storage.

  D. Provision a FastConnect link to the closest OCI region and configure a public peering virtual circuit

  E. Create an OCI Object Storage Standard tier bucket. Configure a lifecycle policy to delete any object that is older than 7 years

  Correct Answer: BD

  The Oracle Services Network is a conceptual network in Oracle Cloud Infrastructure that is reserved for Oracle services. These services have public IP addresses that you typically reach over the internet. However, you can access the Oracle

  Services Network without the traffic going over the internet. There are different ways, depending on which of your hosts need the access:

  Hosts in your on-premises network:

  -Private access through a VCN with FastConnect private peering or VPN Connect: The on- premises hosts use private IP addresses and reach the Oracle Services Network by way of the VCN and the VCN's service gateway.

  -Public access with FastConnect public peering: The on-premises hosts use public IP addresses. regarding which Fastconnect Public peering: To access public services in Oracle Cloud Infrastructure without using the internet. For example, Object Storage, the Oracle Cloud Infrastructure Console and APIs, or public load balancers in your VCN. Communication across the connection is with IPv4 public IP addresses. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet. With FastConnect, that traffic goes over your private physical connection. so Answer 4 will be the best answer that meets the customer requirement A service gateway lets your virtual cloud network (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT is required to reach those specific services. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet. Object Lifecycle Management lets you automatically manage the archiving and deletion of objects. By using Object Lifecycle Management to manage your Object Storage and Archive Storage data, you can reduce your storage costs and the amount of time you spend managing data.

• Question 23:

  As a solution architect, you are designing a web application to be deployed across multiple Oracle Cloud Infrastructures (OCI) regions for a global audience. Your goal is that users from each region should access the application web servers

  deployed in their own geographical OCI location.

  Which OCI feature can be used to achieve this?

  A. OCI Traffic Management IP Prefix steering policy

  B. OCI Global Load balancers

  C. OCI Public Load Balancers

  D. OCI Traffic Management GeoLocation steering policy

  Correct Answer: D

• Question 24:

  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 to automatically tag a resource with the user name.

  B. 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.

  C. Create tag variables to automatically tag a resource with the user name.

  D. Create a default tag for each compartment, which ensure that appropriate tags are applied at resource creation

  E. Create tag variables for each compartment to automatically tag a resource with the user name.

  Correct Answer: C

  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. ${} 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. https://docs.cloud.oracle.com/en-us/iaas/Content/Tagging/Tasks/managingtagdefaults.htm

• Question 25:

  An upcoming e-commerce company has deployed their online shopping application on OCI. The application was deployed on compute instances with autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend.
