• Question 102:

  You are working as a solutions architect for an online retail store In Frankfurt which uses multiple compute instance VMs spread among three availability domains In the eu-frankfurt-1 region. You noticed the website Is having very high traffic,

  so you enabled autoscaling to sun tee me no f your application but, you observed that one of the availability domains is not receiving any traffic.

  What could be wrong In this situation?

  A. Autoscaling only works with single availability domains.
  B. You have to manually acid all three availability domains to your load balancer configuration.
  C. Autoscaling can be enabled for multiple availability domains only in uk-london t region.
  D. Autoscaling is using an Instance Pool configured to create instances in two availability Domains.
  E. You forgot to attach a load balancer to your instance pool configuration.
  D. Autoscaling is using an Instance Pool configured to create instances in two availability Domains.

  ---

  Autoscaling lets you 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.

  you can associate a load balancer with an instance pool. If you do this, when you add an instance to the instance pool, the instance is automatically added to the load balancer's backend set . After the instance reaches a healthy state (the

  instance is listening on the configured port number), incoming traffic is automatically routed to the new instance.

  Instance pools let you provision and create multiple Compute instances based off the same configuration, within the same region.

  By default, the instances in a pool are distributed across all fault Domains in a best-effort manner based on capacity. If capacity isn't available in one fault domain, the instances are placed in other fault domains to allow the instance pool to

  launch successfully. In a high availability scenario, you can require that the instances in a pool are evenly distributed across each of the fault domains that you specify. When sufficient capacity isn't available in one of the fault domains, the

  instance pool will not launch or scale successfully, and a work request for the instance pool will return an "out of capacity" error. To fix the capacity error, either wait for capacity to become available,

  or use the UpdateInstancePool operation to update the placement configuration (the availability domain and fault domain) for the instance pool.

  during create the instance pool you can select the location where you want to place the instances" In the Availability Domain list, select the availability domain to launch the instances in. If you want the instances in the pool to be placed evenly

  in one or more fault domains, select the Distribute instances evenly across selected fault domains check box. Then, select the fault domains to place the instances in.

  OCI Traffic Management Steering Policies can account for health of answers to provide failover capabilities, provide the ability to load balance traffic across multiple resources, and account for the location where the query was initiated to provide a simple, flexible and powerful mechanism to efficiently steer DNS traffic. Public Load Balancer Accepts traffic from the internet using a public IP address that serves as the entry point for incoming traffic. Load balancing service creates a primary load balancer and a standby load balancer, each in a different availability domain

• Question 106:

  You are a solutions architect for a global health care company which has numerous data centers around the globe. Due to the ever growing data that your company is storing, you were Instructed to set up a durable, cost effective solution to archive you data from your existing on-premises tape based backup Infrastructure to Oracle Cloud Infrastructure (OCI). What is the most-effective mechanism to Implement this requirement?

  A. Use the File Storage Service in OCI and copy the data from your existing tape based backup to the shared file system
  B. Setup an on premises OCI Storage Gateway which will back up your data to OCI Object Storage Archive tier.(Correct)
  C. Setup an on premises OCI Storage Gateway which will back up your data to OCI object Storage Standard tier. Use Object Storage life cycle policy management to move any data older than 30 days from Standard to Archive tier.
  D. Setup an on-promises OCI Storage Gateway which will back up your data to OCI Object Storage Standard
  E. Setup fastConnect to connect your on premises network to your OCI VCN and use rsync tool to copy your data to OCI Object Storage Archive tier.
  B. Setup an on premises OCI Storage Gateway which will back up your data to OCI Object Storage Archive tier.(Correct)

  ---

  Oracle Cloud Infrastructure offers two distinct storage tiers for you to store your unstructured data. Use the Object Storage Standard tier for data to which you need fast, immediate, and frequent access. Use the Archive Storage service's Archive tier for data that you access infrequently, but which must be preserved for long periods of time. Both storage tiers use the same manageable resources (for example, objects and buckets). The difference is that when you upload a file to Archive Storage, the object is immediately archived. Before you can access an archived object, you must first restore the object to the Standard tier. you can use Storage Gateway to move files to Oracle Cloud Infrastructure Archive Storage as a cost effective backup solution. You can move individual files and compressed or uncompressed ZIP or TAR archives. Storing secondary copies of data is an ideal use case for Storage Gateway.

• Question 107:

  There are two compartments: Networks and Devlnstances There are two groups: NetworkAdmins with a user named Nick, and Devs with a user named Dave The following IAM policies are being used: Allow group NetworkAdmins to manage virtual-network-family in compartment Networks Allow group NetworkAdmins to manage instance-family in compartment Networks Allow group Devs to use virtual-network-family in compartment Networks Allow group Devs to manage all-resources in compartment

  Devlnstances Nick creates a VCN in Networks compartment. Dave creates a VCN in Devlnstances compartment. Which of the following statements is INCORRECT?

  A. Dave launches instances in Devlnstances using the VCN in Networks compartment
  B. Nick cannot launch new instances in Devlnstances compartment
  C. Nick launches instances in Networks using VCN in Devlnstances compartment
  D. Dave cannot launch new instances in Networks compartment
  C. Nick launches instances in Networks using VCN in Devlnstances compartment

• Question 108:

  Given this compartment structure:

  

  You are managing a compute instance that currently resides in the Compute compartment. The Virtual Cloud Network (VCN) into which the compute instance was originally deployed, also resides in this compartment. To support a project-related task, you need to move just the compute instance to the SysTest-Team compartment. You log into your Oracle Cloud Infrastructure (OCI) account and use the Move Resource option to place the compute instance in the new compartment. What will be the result of your attempt to move the compute instance to the new compartment? (Choose the best answer.)

  A. The move will be successful. The compute instance's public and private IP addresses will stay the same. The compute instance will remain associated with the VCN from the source compartment.
  B. The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the compute instance can be moved.
  C. After moving the compute instance, you must move the compute instance VNIC as a separate action. The public and private IP addresses of the instance will remain unchanged and it will still be associated with the VCN from the source compartment.
  D. The move will be successful. However, the compute instance's public and private IP addresses will change, and it will be associated to the first VCN that was created in the new, target compartment.
  C. After moving the compute instance, you must move the compute instance VNIC as a separate action. The public and private IP addresses of the instance will remain unchanged and it will still be associated with the VCN from the source compartment.
