1Z0-1085-26 Core Oci Services Practice Test 3 — 15 Questions

Question 1

Which THREE of the following statements about OCI Object Storage lifecycle management rules are true? (Choose three.)

Accepted Answer

Lifecycle rules can be applied to specific object name prefixes within a bucket.. Option B is correct because OCI Object Storage lifecycle policy rules support a name filter (objectNameFilter with inclusionPrefixes/inclusionPatterns), so a rule can target only objects whose names match a specific prefix within a bucket. Option C is correct because a lifecycle rule can specify the DELETE action with an age (in days) so objects are automatically removed after the defined period. Option D is correct because lifecycle rules support the ARCHIVE action, which automatically transitions objects from Standard to Infrequent Access or Archive storage based on age. Option A is wrong because lifecycle rules are evaluated and executed automatically by the service on a schedule, not manually via the OCI CLI on each upload. Option E is wrong because lifecycle rules are not restricted to buckets with versioning disabled; they work with versioning-enabled buckets as well, and versioning is not a prerequisite condition for using lifecycle policies.

Answer

Lifecycle rules require manual execution via the OCI CLI every time objects are uploaded.

Answer

Lifecycle rules are restricted to buckets with versioning disabled.

Question 2

Which THREE of the following parameters can be configured when setting up an OCI Compute Autoscaling configuration? (Choose three.)

Accepted Answer

Metric triggers such as CPU utilization or memory utilization thresholds. Compute autoscaling allows setting threshold metrics like CPU or memory utilization, setting minimum and maximum instance counts, and cooldown periods.

Answer

Automatic database schema migration scripts upon scale-out

Question 3

A cloud architect needs to deploy a lightweight web application in OCI that requires rapid provisioning without managing underlying virtual machine infrastructure, operating systems, or cluster orchestration. Which OCI service should be selected?

Accepted Answer

OCI Container Instances. OCI Container Instances provide a serverless experience to run containers quickly without needing to manage servers or clusters like OKE.

Answer

OCI Functions

Answer

Oracle Container Engine for Kubernetes (OKE)

Answer

Compute Standard Flex Instances

Question 4

An enterprise application running on Oracle Cloud Infrastructure requires block storage that dynamically scales performance levels up to 300 IOPS per GB with a maximum performance target independent of volume capacity scaling. Which Block Volume performance tier should the administrator configure?

Accepted Answer

Higher Performance. The Higher Performance tier is designed for workloads requiring up to 300 IOPS/GB, allowing high performance independent of capacity.

Answer

Lower Cost

Answer

Ultra High Performance

Answer

Balanced

Question 5

An administrator is configuring OCI Block Volume backups for production workloads. Which TWO features are natively supported by the OCI Block Volume service? (Choose two.)

Accepted Answer

Incremental backups that capture only blocks changed since the last backup. Option A is correct because OCI Block Volume backups are incremental by default: the first backup is a full backup, and every subsequent backup only captures the blocks that changed since the last backup, reducing storage consumption and backup time. Option B is correct because OCI provides native backup policies with predefined schedules—Bronze (monthly), Silver (weekly), and Gold (daily)—which can be assigned to volumes or volume groups for automated backups. Option C is not correct because OCI Block Volume does not natively perform real-time synchronous cross-region mirroring; cross-region replication is asynchronous and is a separate Block Volume replication feature, not automatic synchronous mirroring. Option D is not correct because backups are stored in OCI Object Storage (or copied across regions), not on local NVMe drives attached to the same server. Option E is not correct because OCI supports cloning a block volume from a backup, but it is not an instantaneous read-only clone operation as described.

Answer

Real-time synchronous mirroring of block volumes across global cloud regions automatically

Answer

Direct backup storage to local NVMe drives on the same server

Answer

Instantaneous read-only block volume cloning

Question 6

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

Accepted Answer

File Storage file systems are encrypted at rest by default.. FSS provides a managed file system accessible via NFSv3 that automatically scales and encrypts data at rest by default.

Answer

File systems require manual capacity planning and provisioning of underlying physical disks.

Answer

File Storage is accessed exclusively through Object Storage REST API calls.

Answer

File Storage is restricted to a single compute instance at a time in read/write mode.

Question 7

Which THREE features or capabilities are associated with OCI Virtual Cloud Network (VCN) Security Lists?

Accepted Answer

Security lists are stateful by default for both inbound and outbound rules.. Option A is correct because OCI security lists are stateful by default: return traffic for an allowed inbound or outbound connection is automatically permitted without needing a matching reverse rule. Option B is correct because OCI allows you to configure a security list as stateless, in which case you must explicitly define rules for both directions of traffic. Option E is correct because a security list functions as a virtual firewall attached to a subnet, containing separate ingress and egress rule sets that control traffic in and out of the subnet. Option C is incorrect because a subnet can be associated with a limited number of security lists (up to five), not an unlimited number. Option D is incorrect because security lists are applied at the subnet level, whereas Network Security Groups are the construct applied at the VNIC level.

Answer

A subnet can be associated with an unlimited number of security lists with no maximum limit.

Answer

Security list rules apply at the individual VNIC level rather than the subnet level.

Question 8

To secure a subnet, you need to define rules that restrict traffic based on the source and destination at the packet level. Which OCI resource provides this stateful security?

Accepted Answer

Security Lists. Security Lists provide stateful packet filtering for all VNICs in a subnet.

Answer

Network Security Groups (NSG)

Answer

Dynamic Routing Gateway

Answer

Route Tables

Question 9

What is the primary function of an OCI Internet Gateway?

Accepted Answer

Public internet access. An Internet Gateway allows bi-directional traffic between a VCN and the public internet.

Answer

Service access

Answer

Private routing

Answer

VPN termination

Question 10

Which TWO OCI compute features help in achieving cost optimization?

Accepted Answer

Preemptible Instances. Preemptible Instances (B) are correct because OCI offers them at a significant discount compared to on-demand pricing; they can be reclaimed by OCI when capacity is needed, making them ideal for fault-tolerant, interruptible workloads and thus a direct cost-optimization feature. Autoscaling (E) is correct because it automatically adjusts the number of compute instances in an instance pool based on performance metrics or schedules, ensuring you provision only the capacity you need and avoid paying for idle resources. GPU Instances (A) are specialized for accelerated workloads and typically carry a price premium, so they are not a cost-optimization feature. Bare Metal (C) provides dedicated physical servers that are generally more expensive and used for performance/isolation needs, not cost reduction. Dedicated Hosts (D) give you sole tenancy of a physical host for compliance or licensing reasons, which also increases cost rather than optimizing it.

Answer

GPU Instances

Answer

Bare Metal

Answer

Dedicated Hosts

Question 11

Answer

Local Peering

Answer

Service Gateway

Question 15

Which THREE of the following OCI services are considered serverless?

Accepted Answer

Functions. OCI Functions (A) is serverless because it runs code on demand in a fully managed FaaS environment where Oracle handles all infrastructure provisioning, scaling, and patching, and you pay only per invocation. OCI Object Storage (B) is serverless because it is a fully managed, elastic object storage service with no servers to provision or manage and consumption-based pricing. OCI Container Instances (D) is serverless because it runs containers without requiring you to manage the underlying compute hosts, providing a serverless container runtime. Compute Instances (C) and Bare Metal (E) are not serverless because they are IaaS offerings where you provision, manage, and pay for dedicated virtual machines or physical servers, retaining control and responsibility for the OS and infrastructure.

Answer

Compute Instances

Answer

Bare Metal
