• Question 142:

  A fast growing E-commerce company has deployed their online shopping application on Oracle Cloud Infrastructure. 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. In order to promote their e- commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints.

  What could be two possible reasons for this situation?

  A. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation.
  B. As part of Autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change.
  C. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.
  D. Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.
  A. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation.
  D. Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.

• Question 143:

  A retail company has several on-premise data centers which span multiple geographical locations. They plan to move many of their business critical applications to Oracle Cloud Infrastructure (OCI). These applications require highly available network connections between on-premises and OCI.

• Question 147:

  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 Groups' 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. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
  B. You are exceeding your volume group backup quota configured.
  C. 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.
  D. A compute instance with multiple block volumes attached cannot move when a compartment is moved.
  A. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

• Question 148:

  Your customer recently ordered for a 1-Gbps Fast Connect connection In ap-tokyo-1 region of Oracle Cloud Infrastructure (OCI). They will us this to one Virtual cloud Network (VCN) in their production (OC1) tenancy and VCN In their development OC1 tenancy

  As a Solution Architect, how should yon configure and architect the connectivity between on premises and VCNs In OCI?

  A. Create two private virtual circuits on the FastConnect link. Create two Dynamic Routing Gateways, one for each VCNs. Attach the virtual circuits to the dynamic routing gateways.
  B. You cannot achieve connectivity using single FastConnect link as the production and the development VCNs-are in separate tenancies. Request one more FastConnect connection.
  C. Create a single private virtual circuit over FastConnect and attach fastConnect to either of the VCN's Dynamic Routing Gateway. Use Remote Peering to peer production and development VCNs.
  D. Create a hub-VCN that uses Dynamic Routing Gateway (DRG) to communicate with on- premises network over FastConnect. Connect the hub-VCN to the production VCN spoke and with development VCN spoke, each peered via their respective local Peering Gateway (LPG)
  D. Create a hub-VCN that uses Dynamic Routing Gateway (DRG) to communicate with on- premises network over FastConnect. Connect the hub-VCN to the production VCN spoke and with development VCN spoke, each peered via their respective local Peering Gateway (LPG)

  ---

  Explanation/Reference:

  There's an advanced routing scenario called transit routing that enables communication between an onpremises network and multiple VCNs over a single Oracle Cloud Infrastructure FastConnect or IPSec VPN.

  The VCNs must be in the same region and locally peered in a hub-and-spoke layout. As part of the scenario, the VCN that is acting as the hub has a route table associated with each LPG (typically route tables are associated with a VCN's

  subnets).

  

• Question 149:

  An eCommerce company is running on Oracle Cloud Infrastructure (OCI) and many compute instances remain unused for the most part of the year except during Black Friday and Christmas. You suggest them to use OCI's

  Autoscaling feature and present them a slide to showcase the features of Autoscaling.

  Which option below is inaccurate in your presentation to the customer?

  A. A cooldown period between Autoscaling events lets the system stabilize at the updated level.
  B. When an instance pool scales in, instances are terminated in this order: the number of instances is balanced across Availability Domains, and then balanced across Fault Domains. Finally, within a Fault Domain, the newest instance is terminated first.
  C. Autoscaling relies on performance metrics such as CPU utilization that are collected by OCI Monitoring service to trigger an Autoscaling event.
  D. Autoscaling requires an instance pool as a pre-requisite so that it can automatically adjust the number of compute instances in an instance pool.
  B. When an instance pool scales in, instances are terminated in this order: the number of instances is balanced across Availability Domains, and then balanced across Fault Domains. Finally, within a Fault Domain, the newest instance is terminated first.

• Question 150:

  You are the Solution Architect that designed this Oracle Cloud Infrastructure (OCI) compartment layout for your organization:

  

  The development team has deployed quite a few instances under 'Compute' Compartment and the operations team needs to list the Instances under the same compartment for their testing. Both teams, development and operations are part of a group called 'Eng-group'

  You have been looking for an option to allow the operations team to list the instances without access any confidential information or metadata of resources.

  Which IAM policy should you write based on these requirements?

  A. Allow group Eng-group to inspect instance-family in compartment Dev-Team:Compute and attach the policy to `Engineering' Compartment
  B. Allow group Eng-group to inspect instance-family in compartment Dev-Team: Compute and attach the policy to 'SysTest Team' Compartment
  C. Allow group Eng-group to read instance-family in compartment Compute and attach the policy to 'Engineering' Compartment.
  D. Allow group Eng-group to read instance-family in compartment Dev-Team-.Compute and attach the policy to'Dev-Team'
  C. Allow group Eng-group to read instance-family in compartment Compute and attach the policy to 'Engineering' Compartment.

  Explanation/Reference:

  Policy Attachment When you create a policy you must attach it to a compartment (or the tenancy, which is the root compartment). Where you attach it controls who can then modify it or delete it. If you attach it to the tenancy (in other words, if the policy is in the root compartment), then anyone with access to manage policies in the tenancy can then change or delete it. Typically that's the Administrators group or any similar group you create and give broad access to. Anyone with access only to a child compartment cannot modify or delete that policy. When you attach a policy to a compartment, you must be in that compartment and you must indicate directly in the statement which compartment it applies to. If you are not in the compartment, you'll get an error if you try to attach the policy to a different compartment. Notice that attachment occurs during policy creation, which means a policy can be attached to only one compartment. Policies and Compartment Hierarchies a policy statement must specify the compartment for which access is being granted (or the tenancy). Where you create the policy determines who can update the policy. If you attach the policy to the compartment or its parent, you can simply specify the compartment name. If you attach the policy further up the hierarchy, you must specify the path. The format of the path is each compartment name (or OCID) in the path, separated by a colon: :: . . . to allow action to compartment Compute so you need to set the compartment PATH as per where you attach the policy as below examples if you attach it to Root compartment you need to specify the PATH as following Engineering:Dev-Team:Compute if you attach it to Engineering compartment you need to specify the PATH as following Dev-Team:Compute if you attach it to Dev-Team or Compute compartment you need to specify the PATH as following Compute Note : in the Policy inspect verb that give the Ability to list resources, without access to any confidential information or user-specified metadata that may be part of that resource.
