1Z0-1085-26 Core Oci Services Practice Test 7 — 15 Questions

Question 1

Which OCI compute feature allows you to run virtual machines on dedicated physical servers allocated exclusively to your organization?

Accepted Answer

Dedicated Virtual Machine Hosts. Dedicated Virtual Machine Hosts in OCI allow you to run virtual machines on dedicated physical servers allocated exclusively to your organization, providing isolation and control over the host. This is ideal for compliance, licensing, or security requirements that mandate dedicated hardware. It is the OCI feature specifically designed for this purpose.

Answer

OCI Container Instances

Answer

Preemptible Instances

Answer

Standard Flexible VM Shapes

Question 2

You need to copy an existing Block Volume backup from your home region to another OCI region for disaster recovery purposes. What feature should you use?

Accepted Answer

Cross-Region Replication for Block Volume Backups. Block Volume Cross-Region Replication allows you to automatically or manually copy volume backups to another OCI region.

Answer

Compute instance live migration

Answer

Local Peering Gateway transfer

Answer

Object Storage Lifecycle rules

Question 3

An application deployed on OCI Compute instances requires custom DNS records that resolve only within a specific VCN and are not exposed to the public internet. Which OCI DNS feature should you configure?

Accepted Answer

Private DNS Zone. Private DNS zones allow you to manage internal domain names that are resolved exclusively within your VCNs.

Answer

Internet Resolver Forwarding

Answer

Traffic Management Steering Policies

Answer

Public DNS Zone

Question 4

Which THREE types of gateways can be attached to an OCI Virtual Cloud Network (VCN)? (Choose three.)

Accepted Answer

NAT Gateway. In OCI, a VCN can have a NAT Gateway (B), which lets instances in a private subnet initiate outbound internet connections without exposing them to inbound traffic, and an Internet Gateway (D), which provides bidirectional internet connectivity for instances in public subnets. A Service Gateway (E) is also attachable to a VCN and enables private access to Oracle services such as Object Storage or Autonomous Database without traversing the internet. By contrast, a Storage Gateway (A) is not an OCI VCN gateway type — OCI offers a Storage Gateway appliance for hybrid on-premises access to Object Storage, but it is not attached to a VCN as a gateway. A Database Gateway (C) is likewise not a VCN-attachable gateway in OCI; database connectivity is handled through other constructs such as private endpoints or the service gateway.

Answer

Storage Gateway

Answer

Database Gateway

Question 5

Which THREE features are provided by OCI Object Storage buckets? (Choose three.)

Accepted Answer

Object Versioning. Object Versioning (B) is a native bucket feature that retains multiple variants of an object when overwritten or deleted, allowing recovery of prior versions. Lifecycle Management Rules (C) let you automatically transition objects between storage tiers (Standard, Infrequent Access, Archive) or delete them based on age or patterns, which is a core bucket capability. Pre-authenticated Requests (E) are bucket-scoped URLs that grant time-limited access to objects without requiring OCI credentials, enabling secure sharing. Options A and D are incorrect because Object Storage is an object-based service accessed via REST/S3-compatible APIs, not a file or block service; NFSv3 mounting belongs to File Storage, and iSCSI block formatting belongs to Block Volume.

Answer

Direct NFSv3 file system mounting

Answer

Block-level iSCSI disk formatting

Question 6

Which TWO statements are true regarding OCI File Storage Service (FSS)? (Choose two.)

Accepted Answer

All data stored in OCI File Storage is encrypted at rest by default.. Option D is correct because OCI File Storage Service encrypts all file system data at rest by default using Oracle-managed keys, with the option to use customer-managed keys in OCI Vault, so no additional configuration is required to achieve encryption at rest. Option E is correct because FSS exposes file systems over the NFSv3 protocol, and a single file system can be mounted concurrently by thousands of compute instances across subnets, availability domains, and even regions via mount targets, making it suitable for shared, highly concurrent workloads. Option A is incorrect because FSS is a managed, durable network file system backed by redundant OCI storage infrastructure, not a single instance's local NVMe drive (that describes instance-local NVMe or Block Volume). Option B is incorrect because FSS file systems scale far beyond 50 GB, with a minimum of 50 GB and the ability to grow to many terabytes (up to 8 PB per file system in current OCI limits). Option C is incorrect because FSS uses NFSv3 over TCP/IP, not iSCSI; iSCSI is the protocol used by OCI Block Volume attachments, not File Storage.

Answer

File storage data is stored entirely within a single compute instance's local NVMe drive.

Answer

File Storage file systems have a hard maximum capacity limit of 50 Gigabytes.

Answer

File Storage requires iSCSI protocol configuration on every client instance.

Question 7

Which TWO methods can be used to connect an on-premises data center to an OCI Virtual Cloud Network? (Choose two.)

Accepted Answer

OCI FastConnect. OCI FastConnect (C) is correct because it provides a dedicated, private physical connection between an on-premises data center and an OCI VCN, bypassing the public internet for higher bandwidth and more consistent latency. OCI Site-to-Site VPN (D) is also correct because it establishes an IPsec VPN tunnel over the public internet between the on-premises customer-premises equipment (CPE) and a Dynamic Routing Gateway (DRG) attached to the VCN, enabling encrypted hybrid connectivity. Internet Gateway with Public IP (A) only provides outbound/inbound internet access for resources in the VCN and does not create a dedicated or private link to an on-premises network. Local Peering Gateway (B) connects two VCNs within the same OCI region, not an on-premises data center. Object Storage Gateway (E) is a service for accessing Object Storage from on-premises or other clouds, not a method for connecting a data center network to a VCN.

Answer

Internet Gateway with Public IP

Answer

Local Peering Gateway

Answer

Object Storage Gateway

Question 8

What is the primary function of a Dynamic Routing Gateway (DRG) in OCI?

Accepted Answer

To provide a path for private traffic between a VCN and on-premises networks or remote VCNs. A DRG acts as a virtual router that provides a path for private traffic between your VCN and locations outside your VCN, such as on-premises networks or other VCNs.

Answer

To route public internet traffic to virtual machines

Answer

To balance HTTP traffic across backend web servers

Answer

To provide private access to regional Oracle Cloud services

Question 9

Which TWO metrics can be monitored using OCI Monitoring service for compute instances? (Choose two.)

Accepted Answer

Memory Utilization. OCI Monitoring ingests metrics published through the OCI Monitoring service, and compute instances emit the agent-based metric Memory Utilization (option B) when the Compute Instance Monitoring plugin is enabled, making it a valid monitorable metric. CPU Utilization (option E) is a default hypervisor-level metric emitted for every compute instance without any agent, so it is also directly monitorable in OCI Monitoring. Options A, C, and D are not compute instance metrics: VCN Route Table Rule Count and Subnet CIDR block utilization are networking/VCN constructs, and Object Storage Bucket Count is an Object Storage service metric, none of which are published as compute instance metrics in OCI Monitoring.

Answer

VCN Route Table Rule Count

Answer

Object Storage Bucket Count

Answer

Subnet CIDR block utilization

Question 10

An administrator needs to configure autoscaling for a compute instance pool so that instances scale out when CPU usage exceeds 80% and scale in when CPU usage drops below 20%. Where is this autoscaling configuration applied?

Accepted Answer

On an Instance Pool. Autoscaling configurations in OCI are linked directly to an Instance Pool to automatically manage the number of instances.

Answer

On the OCI Load Balancer backend set

Answer

Directly on the VCN Route Table

Answer

Inside an individual Compute VM's operating system configuration

Question 11

You need to create a container cluster in OCI where Oracle manages the Kubernetes control plane and you manage the worker nodes. Which service do you deploy?

Accepted Answer

Oracle Container Engine for Kubernetes (OKE). Oracle Container Engine for Kubernetes (OKE) is a managed service where Oracle manages the Kubernetes master control plane.

Answer

OCI Container Instances

Answer

OCI Functions

Answer

Compute Instances with Docker

Question 12

Which OCI Object Storage tier is optimized for storing active data that requires fast and frequent access with lowest latency?

Accepted Answer

Standard Storage. Standard storage tier is the default tier for hot data that is accessed frequently.

Answer

Archive Storage

Answer

Infrequent Access Storage

Answer

Backup Storage Tier

Question 13

Which THREE actions can be performed using OCI Object Storage features? (Choose three.)

Accepted Answer

Enable object versioning to protect against accidental data deletion. Option B is correct because OCI Object Storage supports object versioning at the bucket level, which retains multiple variants of an object so that accidental deletions or overwrites can be recovered. Option C is correct because Object Storage lets you create pre-authenticated requests (PARs) that grant time-limited, URL-based access to objects or buckets without requiring OCI credentials, ideal for temporary public sharing. Option D is correct because Object Storage supports cross-region replication, which asynchronously and automatically copies objects from a source bucket to a destination bucket in another region for durability and compliance. Option A is incorrect because Object Storage buckets cannot be attached as iSCSI block volumes; that capability belongs to OCI Block Volume service. Option E is incorrect because Object Storage buckets are accessed via REST/S3-compatible APIs, not mounted directly as NFSv3 file systems; NFS-style shared file access is provided by the OCI File Storage service.

Answer

Attach the bucket as an iSCSI block storage disk to a VM

Answer

Mount the bucket directly as a local NFSv3 file system on compute instances

Question 14

You want to host a static HTML website with images and JavaScript files entirely on OCI without provisioning any virtual machine web servers. Where should you store and serve these website files?

Accepted Answer

OCI Object Storage Public Bucket. OCI Object Storage supports hosting public static websites by configuring public buckets to serve web content directly via HTTP/HTTPS.

Answer

OCI File Storage Service

Answer

Block Volume Storage

Answer

OCI Container Instances

Question 15

What is the term used in OCI to describe a software-defined version of a traditional physical network, including subnets, route tables, and gateways?

Accepted Answer

Virtual Cloud Network (VCN). A Virtual Cloud Network (VCN) is a customizable, software-defined private network that you set up in OCI.

Answer

Subnet Gateway

Answer

Local Peering Network

Answer

Virtual Private Network (VPN)
