Question 1

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

Options:

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

Question 2

You are a migration architect responsible for migrating 100 TB of on-premises data to Oracle Cloud Infrastructure (OCI). Because of limited bandwidth and security concerns, transferring the data over the public Internet is not feasible.

Options:

A.

Snowball

B.

Data Transfer Service

C.

Data Integration

D.

Storage Gateway

Question 3

Which three transfer mediums does the OCI Database Migration service use to perform the initial load of the databases?

Options:

A.

B.

Data Pump via Object Storage

C.

Data Pump via network link

D.

Data Guard via replication

E.

Data Pump dump upload via OCI CLI

Question 4

You are setting up replication in the Oracle Cloud Infrastructure (OCI) File Storage service. What is a key requirement for the target file system?

Options:

A.

It must be located in a different region than the source file system

B.

Only a file system that has been exported can be used as a target file system

C.

It must not have been previously exported

D.

It must be located in the same availability domain as the source file system

Question 5

Which Hybrid Cloud Extension (HCX) migration type is designed for large-scale migration of workloads that cannot afford downtime?

Options:

A.

HCX vMotion

B.

HCX OS Assisted Replication

C.

HCX Replication Assisted vMotion

D.

HCX Bulk Migration

Question 6

A team of migration cloud architects are evaluating different storage options for deploying virtual machines (VMs) in Oracle Cloud VMware Solution (OCVS). They are comparing VMware vSAN and OCI Block Storage to determine the best fit for their needs. Which two statements accurately reflect the usage of vSAN and OCI Block Storage in OCVS?

Options:

A.

OCI Block Storage inherently provides better IOPS performance than vSAN for all workload types

B.

OCI Block Storage can be scaled up or down independently of compute resources, unlike vSAN which scales with the cluster

C.

vSAN requires an external network connectivity to synchronize data across hosts, whereas OCI Block Storage does not

D.

vSAN is tightly integrated with VMware's SDDC ecosystem, thus allowing for storage policies to be directly applied to VMs, whereas OCI Block Storage operates as independent block volumes

E.

OCI Block Storage can utilize VMware-specific storage policies for VM provisioning and management, just like vSAN in the OCVS environment

Question 7

Which statement accurately describes the routing mechanism within a Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI)?

Options:

A.

Each subnet within a VCN employs multiple route rules, allowing for diverse routing paths based on traffic priorities

B.

A subnet in a VCN is associated with a single route table, dictating how outbound traffic from all Virtual Network Interface Cards (VNICs) within that subnet is directed

C.

If no route rule matches the network traffic you intend to route outside the VCN, the traffic is sent to the Internet

D.

VCN local routing necessitates manual configuration of route rules to facilitate infrastructure communication

Question 8

What capability does Oracle Cloud Infrastructure (OCI) Storage Gateway provide for connecting on-premises applications with OCI Object Storage?

Options:

A.

It enables seamless integration with on-premises databases for real-time data synchronization

B.

It enables seamless integration with OCI Block Volumes for real-time data synchronization

C.

It provides a bridge for applications to write data to OCI Object Storage using NFS protocol but requires application modification to uptake the REST APIs

D.

It provides a bridge for applications to write data to OCI Object Storage using NFS protocol, without requiring modifications to the applications for REST API integration

Question 9

You are planning to configure VMware Hybrid Cloud Extension (HCX) for a migration from an on-premises data center to Oracle Cloud VMware Solution (OCVS). What are the primary roles of the HCX Manager and HCX Connector?

Options:

A.

Both HCX Manager and HCX Connector are deployed in the OCVS environment to facilitate bidirectional migrations between cloud instances

B.

The HCX Manager is installed in the source environment to initiate migrations, whereas the HCX Connector receives the migration traffic in the target OCVS environment

C.

The HCX Manager is deployed in the OCVS environment as the Tunnel receivers, whereas the HCX Connector is installed in the on-premises environment as the Tunnel initiators

D.

The HCX Connector is responsible for WAN optimization and network extension in the OCVS environment, whereas the HCX Manager handles these tasks in the on-premises environment

Question 10

You plan to use Oracle Zero Downtime Migration to perform offline or online migration of Oracle databases, where the migration method type may be Physical or Logical. Which three migration methods does Oracle Zero Downtime Migration provide?

Options:

A.

Remote Cloning

B.

OCI Golden Gate

C.

Data Pump

D.

Data Guard

E.

Unplug and Plug Database

Question 11

Which resource type would you create in Full Stack Disaster Recovery (FSDR) to represent a consistency grouping of Oracle Cloud Infrastructure (OCI) resources for disaster recovery purposes?

Options:

A.

Disaster Recovery Plan

B.

Disaster Recovery Protection Group

C.

Disaster Recovery Instance

D.

Disaster Recovery Policy
