Question 4

You have been tasked with provisioning an Oracle Cloud Infrastructure Container Engine for
Kubernetes (OKE) cluster to deploy new applications and manage existing ones. Which two
statements are FALSE?

  • A. To access the cluster using kubectl, you have to set up a Kubernetes manifest file stored in the $HOME/.manifest directory
  • B. When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file
  • C. The only available option when a cluster's Kubernetes API endpoint has a public IP address is to control the cluster locally using kubectl and the Kubernetes Dashboard
  • D. To access the cluster using kubectl, you have to set up a Kubernetes configuration file stored in the $HOME/.kube directory
Mark Question:
Answer:

A, C


Explanation:
Setting up a Kubernetes manifest file in the $HOME/.manifest directory is not a standard practice for
accessing a Kubernetes cluster using kubectl. Manifest files are used to define and manage
Kubernetes resources, such as pods, deployments, and services, but they are not used for configuring
access to the cluster.
While controlling the cluster locally using kubectl and the Kubernetes Dashboard is one way to
interact with a cluster, it is not the only available option when a cluster's Kubernetes API endpoint
has a public IP address. You can also access and manage the cluster remotely using kubectl from any
environment that has network connectivity to the cluster.

Question 5

What is the primary purpose of deploying a Remote Agent Appliance in an on-premises environment
when using the Oracle Cloud Migrations (OCM) service?

  • A. To perform real-time data compression and deduplication of the source data to be transferred to OCI
  • B. To serve as a temporary storage buffer to cache data before it is transferred to OCI
  • C. To facilitate direct VPN connectivity between the on-premises data center and OCI
  • D. To discover on-premises workloads and provide detailed inventory information to OCI
Mark Question:
Answer:

D


Explanation:
The primary purpose of deploying a Remote Agent Appliance in an on-premises environment is to
discover on-premises workloads and provide detailed inventory information to OCI. This information
is crucial for planning and executing migrations to Oracle Cloud.

Question 6

You are setting up Oracle Cloud Migrations (OCM) service for migrating workloads to Oracle Cloud
Infrastructure (OCI). As part of the initial configuration, a Source Environment is created with Remote
connection agents and Agent Dependency. However, the Replication plugin indicates the status as
Inactive. What is the likely reason for this issue?

  • A. The replication plugin does not support encrypted VM disk files
  • B. The OCI tenancy has exceeded its service limit for compute instances, preventing the replication plugin from provisioning necessary resources
  • C. The source VMs are using an unsupported file system that the replication plugin is unable to process
  • D. The VDDK (Virtual Disk Development Kit) file required by the replication plugin is missing in the OCI Object Storage
Mark Question:
Answer:

D


Explanation:
The VDDK file is essential for the replication plugin to access and replicate VM disk files. If this file is
missing in the OCI Object Storage, the replication plugin will be unable to function properly, resulting
in an inactive status.

Question 9

In Oracle Cloud Infrastructure (OCI), how are Security Lists different from Network Security Groups
(NSGs) in terms of their functionality and application?

  • A. Security Lists offer more advanced features such as intrusion detection and prevention, whereas NSGs focus solely on packet filtering and routing
  • B. NSGs are primarily used for inbound traffic control, while Security Lists are exclusively utilized for outbound traffic control within a subnet
  • C. A Security List defines a set of security rules that applies to all the VNICs in a subnet whereas a Network Security Group lets you define a set of security rules that applies to a group of VNICs in a Virtual Cloud Network (VCN)
  • D. Security Lists and NSGs are identical in functionality but differ only in naming conventions based on the OCI region where they are deployed
Mark Question:
Answer:

C


Explanation:
A Security List in OCI defines a set of security rules that apply to all the Virtual Network Interface
Cards (VNICs) within a subnet, while a Network Security Group (NSG) allows you to define a set of
security rules that apply to a specific group of VNICs within a Virtual Cloud Network (VCN).
