• Question 141:

  A customer has established an Oracle Cloud Infrastructure (OCI) FastConnect connection to OCI. The virtual circuit is up and routes are being advertised from the customer's end, however the customer is unable to ping from compute

  instances inside the virtual cloud network (VCN) to servers residing in its on-premises data center.

  Which two options on OCI would remedy this situation? (Choose two.)

  A. Modify the route table associated with the VCN subnet in which the instance resides. Add a route to the customer's on-premises network via the Dynamic Routing Gateway (DRG).
  B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow ICMP traffic to the customer's on-premises network.
  C. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful ingress rule to allow ICMP traffic from anywhere.
  D. Modify the default VCN route table to add a route back to the customer's on-premises network via the DRG.
  A. Modify the route table associated with the VCN subnet in which the instance resides. Add a route to the customer's on-premises network via the Dynamic Routing Gateway (DRG).
  B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow ICMP traffic to the customer's on-premises network.

• Question 143:

  How can you provide users access to an existing compartment?

  A. by granting users access to a compartment when the compartment is created
  B. by adding users to a group and defining a policy to provide the group access to the compartment
  C. by adding users to a compartment. All users in the compartment will have access to the objects in the compartment.
  D. by granting access directly to the user when the user is created
  B. by adding users to a group and defining a policy to provide the group access to the compartment

  ---

  A policy is a document that specifies who can access which Oracle Cloud Infrastructure resources that your company has, and how. A policy simply allows a group to work in certain ways with specific types of resources in a particular

  compartment

  In general, here's the process an IAM administrator in your organization needs to follow:

  Define users, groups, and one or more compartments to hold the cloud resources for your organization.

  Create one or more policies, each written in the policy language. Place users into the appropriate groups depending on the compartments and resources they need to work with.

  Provide the users with the one-time passwords that they need in order to access the Console and work with the compartments. For more information,

• Question 144:

  You create an autoscaling configuration of Linux compute instances in Oracle Cloud Infrastructure (OCI). You noticed that your application is running slow. After checking your compute instances, you noticed that autoscaling is not launching

  additional instances,

  even though the existing compute instances already have high memory usage.

  How can you resolve this issue?

  A. Modify the scaling policy to monitor memory usage and scale up the number of instances when it meets the threshold.
  B. Modify the scaling policy to monitor CPU usage and scale up the number of instances when it meets the threshold.
  C. Install the monitoring agent to all compute instances which will trigger the autoscaling group.
  D. Install OCI SDK in all compute instances and create a script that will trigger the autoscaling event if there is high memory usage.
  B. Modify the scaling policy to monitor CPU usage and scale up the number of instances when it meets the threshold.

• Question 145:

  Which two statements are true about Oracle Cloud Infrastructure (OCI) DB Systems?

  A. Customers have no control over database patching.
  B. The database and backups are encrypted by default.
  C. Customers can consolidate multiple database homes on a single virtual machine database host.
  D. Customers can manage the TDE Wallet after DB Systems is provisioned.
  B. The database and backups are encrypted by default.
  D. Customers can manage the TDE Wallet after DB Systems is provisioned.

  ---

  All databases created in Oracle Cloud Infrastructure are encrypted using transparent data encryption (TDE).

  Oracle Cloud Infrastructure encrypts all managed backups in the object store. Oracle uses the Database Transparent Encryption feature by default for encrypting the backups. and the customers can manage the TDE Wallet after DB Systems

  are provisioned.

• Question 146:

  Which statement is true about interconnecting Virtual Cloud Network (VCN)?

  A. VCNs support transitive peering.
  B. Peering VCNs should not have overlapping CIDR blocks.
  C. VCNs must be in the same tenancy to be peered.
  D. The only way to interconnect VCNs is through peering.
  B. Peering VCNs should not have overlapping CIDR blocks.

• Question 147:

  What is a "transfer package" when transferring data to OCI via the OCI Data Transfer Service?

  A. A transfer package is the logical representation of the physical shipment containing the HDD transfer devices that you ship to Oracle to upload to OCI.
  B. A transfer package is the software Oracle provides for you to prepare transfer devices for shipment to Oracle
  C. A transfer package contains the physical devices.
  D. A transfer package is the archive file that the Data Transfer Service Utility (dts) writes to the transfer device.
  A. A transfer package is the logical representation of the physical shipment containing the HDD transfer devices that you ship to Oracle to upload to OCI.

• Question 148:

  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?

  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.
  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.
  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.
  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.
  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.

  ---

  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 Reference: https://docs.cloud.oracle.com/en-us/iaas/Content/GSG/Tasks/usingaudit.htm

• Question 149:

  Which two options are necessary for achieving high availability on Oracle Cloud Infrastructure?

  B. Attach your block volume form Availability Domain 1 to a compute instance in Availability Domain 2 (and vice versa) so that they are highly available.
  C. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
  D. Store your database files on Object Storage so that they are available in all Availability Domains in all regions.
  E. Distribute your application servers across all Availability Domains within a region.
  C. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
  E. Distribute your application servers across all Availability Domains within a region.

• Question 150:

  You are designing a shared storage solution for your company in Oracle Cloud Infrastructure. The proposed storage solution should allow users to create a hierarchical structure (similar to the directory structure in Linux or Windows based

  systems). The solution should provide data encryption and a large amount of storage space.

  Which would be the best implementation strategy?

  A. Use block storage. Create and attach a large block storage volume to one compute instance. Assign a public IP to the compute instance. Store data on the block storage and access it by connecting to the compute instance.
  B. Use object storage. Create a single namespace and multiple buckets to create the hierarchical directory structure.
  C. Use object storage. Create multiple namespaces with one bucket each. Make the buckets publicly accessible.
  D. Use file storage service. Create a file system and a mount target. Share the private IP of the mount target.
