  • C. You did not setup a Route Table associated with load Balancer's subnet
  • D. One of the two working web servers In the other region did not pass Its HTTP health check
  • E. Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.

Answer: A,B

 

NEW QUESTION 44
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 to automatically tag a resource with the user name.
  • C. Create a policy to automatically tag a resource with the user name.
  • D. Create a policy using 1AM requiring users to tag specific resources. This will allow a user to launch compute instances on\y if certain tags were defined.
  • E. Create tag variables for each compartment to automatically tag a resource with the user name.

Answer: B

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.

NEW QUESTION 45
An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two

  • A. Auto scaling also scales IO throughput linearly along with CPU
  • B. The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling
  • C. Enabling auto scaling does not change the concurrency and parallelism settings
  • D. The maximum CPU cores that will be automatically allocated for this database is 16 CPUs

Answer: A,C

Explanation:
Explanation
Auto scaling is enabled by default when you create an Autonomous Database instance or you can use Scale Up/Down on the Oracle Cloud Infrastructure console to enable or disable auto scaling.
With auto scaling enabled the database can use up to three times more CPU and IO resources than specified by the number of OCPUs currently shown in the Scale Up/Down dialog. When auto scaling is enabled, if your workload requires additional CPU and IO resources the database automatically uses the resources without any manual intervention required.
Enabling auto scaling does not change the concurrency and parallelism settings for the predefined services IO throughput depends on the number of CPUs you provision and scales linearly with the number of CPUs.

NEW QUESTION 47
A retail company has several on-premises data centers which span multiple geographical locations. They plan to move some of their applications from on-premises data centers to Oracle Cloud Infrastructure (OCI). For these applications running in OCI, they still need to interact with applications running on their on-premises data centers to Oracle Cloud Infrastructure (OCI). for these applications running in OCI. they still need to interact with applications running on their on-premises data centers. These applications require highly available, fault-tolerant network connections between on premises data centers and OCI.
Which option should you recommend to provide the highest level of redundancy?

  • A. Set up both IPSec VPN and FastConnect to connect your on premises data centers to Oracle Cloud Infrastructure.
  • B. If your data centers span multiple, geographical locations, use only the specific IP address as a static route for the specific geographical location
  • C. Use FastConnect private peering only to ensure secure access from your data center to Oracle Cloud Infrastructure
  • D. Oracle cloud Infrastructure provides network redundancy by default so that no other operations are required
  • E. Set up a single IPSec VPN connection (rom your data center to Oracle Cloud Infrastructure since It is cost effective

Answer: B

Explanation:
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.

 

NEW QUESTION 48
You work for a German company as the Lead Oracle Cloud Infrastructure architect. You have designed a highly scalable architecture for your company's business critical application which uses the Load Balancer service auto which uses the Load Balancer service, autoscaling configuration for the application servers and a 2 Node VM Oracle RAC database. During the peak utilization period of the- application yon notice that the application is running slow and customers are complaining. This is resulting in support tickets being created for API timeouts and negative sentiment from the customer base.
What are two possible reasons for this application slowness?

  • A. Autoscaling configuration for the application servers didn't happen due to service limit breach of the VM shapes used by the application servers
  • B. The Load Balancer configuration is not sending traffic to the listener of the application servers.
  • C. Autoscaling configuration for the application servers didn't happen due to compartment quota breach of the VM shapes used by the application servers.
  • D. The Load Balancer doesn't have a Network Security Group to allow traffic to the application servers.
  • E. Autoscaling configuration for the application servers didn't happen due to IAM policy that's blocking access to the application server compartment

Answer: A,C

Explanation:
Autoscaling
Autoscaling enables you to automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.
Prerequisites
- You have an instance pool. Optionally, you can attach a load balancer to the instance pool. For steps to create an instance pool and attach a load balancer, see Creating an Instance Pool.
- Monitoring is enabled on the instances in the instance pool. For steps to enable monitoring, see Enabling Monitoring for Compute Instances.
- The instance pool supports the maximum number of instances that you want to scale to. This limit is determined by your tenancy's service limits.
About Service Limits and Usage
When you sign up for Oracle Cloud Infrastructure, a set of service limits are configured for your tenancy.
The service limit is the quota or allowance set on a resource. For example, your tenancy is allowed a maximum number of compute instances per availability domain. These limits are generally established with your Oracle sales representative when you purchase Oracle Cloud Infrastructure.
Compartment Quotas
Compartment quotas are similar to service limits; the biggest difference is that service limits are set by Oracle, and compartment quotas are set by administrators, using policies that allow them to allocate resources with a high level of flexibility.

NEW QUESTION 50
A cloud consultant is working on implementation project on OCI. As part of the compliance requirements, the objects placed in object storage should be automatically archived first and then deleted. He is testing a Lifecycle Policy on Object Storage and created a policy as below:
[ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes": "doc"] },
"timeAmount": 5, "timeunit": "DAYS", "isEnabled": true },
{ "name": "Delete_doc", "action": "DELETE", "objectNameFilter": "inclusionPrefixes": [ "doc"]
1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }
What will happen after this policy is applied?

  • A. All objects with names starting with "doc" will be deleted after 5 days of object creation
  • B. All the objects having file extension ".doc" will be archived for 5 days and will be deleted 10 days after object creation
  • C. All the objects having file extension ".doc" will be archived 5 days after object creation
  • D. All the objects with names starting with "doc" will be archived 5 days after object creation and will be deleted 5 days after archival

Answer: A

Explanation:
Explanation
Object Lifecycle Management works by defining rules that instruct Object Storage to archive or delete objects on your behalf within a given bucket. A bucket's lifecycle rules are collectively known as an object lifecycle policy.
You can use a rule to either archive or delete objects and specify the number of days until the specified action is taken.
A rule that deletes an object always takes priority over a rule that would archive that same object.

NEW QUESTION 60
An insurance company is storing critical financial data in the OCI block volume. This volume is currently encrypted using oracle managed keys. Due to regulatory compliance, the customer wants to encrypt the data using the keys that they can control and not the keys which are controlled by Oracle.
What of the following series of tasks are required to encrypt the block volume using customer managed keys?

  • A. Create a master encryption key, create a data encryption key, decrypt the block volume using existing oracle managed keys, encrypt the block volume using the data encryption key
  • B. Create a vault, import your master encryption key into the vault, generate data encryption key, assign data encryption key to the block volume
  • C. Create a master encryption key, create a new version of the encryption key, decrypt the block volume using existing oracle managed keys and encrypt using new version of the encryption key
  • D. Create a vault, create a master encryption key in the vault, assign this master encryption key to the block volume

Answer: D

Explanation:
Oracle Cloud Infrastructure Vault lets you centrally manage the encryption keys that protect your data and the secret credentials that you use to securely access resources. You can use the Vault service to create and manage the following resources:
Vaults
Keys
Secrets
Vaults securely store master encryption keys and secrets that you might otherwise store in configuration files or in code.
The Vault service lets you create vaults in your tenancy as containers for encryption keys and secrets. If needed, a virtual private vault provides you with a dedicated partition in a hardware security module (HSM), offering a level of storage isolation for encryption keys that's effectively equivalent to a virtual independent HSM.

NEW QUESTION 63
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 Traffic Management with Failover Steering policy
  • B. OCI DNS and Traffic Management with Geolocation Steering policy
  • C. OCI DNS and Traffic Management with Load Balancer Steering policy
  • D. OCI DNS and OCI Load Balancer Service

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.
