1Z0-1085-26 Core Oci Services Practice Test 17 — 15 Questions

Question 1

Which OCI service is highly recommended for storing large amounts of unstructured data such as images and backups?

Accepted Answer

Object Storage. Object Storage is designed for unstructured, massive-scale data storage.

Answer

Block Volume

Answer

File Storage

Answer

Memory

Question 2

When using an OCI Load Balancer, which protocol is recommended for securing traffic?

Accepted Answer

HTTPS. HTTPS (via SSL/TLS certificates) is the standard for securing traffic.

Answer

HTTP

Answer

Telnet

Answer

FTP

Question 3

What is the purpose of a Pre-Authenticated Request in Object Storage?

Accepted Answer

Temporary access. PARs allow temporary, time-bound access to objects without requiring user credentials.

Answer

Administrative access

Answer

Permanent access

Answer

Encryption management

Question 4

Which of the following is a capability of the OCI Block Volume service?

Accepted Answer

Volume cloning. Block volumes support automatic and manual backups to Object Storage.

Answer

Global replication

Answer

Direct console access

Answer

Automatic OS patching

Question 5

You need to allow your OKE cluster to access a private database. Where should the database be placed for the best security practice?

Accepted Answer

Private subnet. Placing the database in a private subnet and using NSGs to allow traffic from the OKE nodes is best practice.

Answer

The same public subnet as OKE

Answer

Management subnet

Answer

Public subnet

Question 6

Which THREE of the following are primary benefits of using Object Storage?

Accepted Answer

High durability. Durability, scalability, and lifecycle management are key features of OCI Object Storage.

Answer

Real-time relational queries

Answer

POSIX-compliant file system

Question 7

Which THREE of the following are valid OCI File Storage Service (FSS) characteristics?

Accepted Answer

Elastic capacity. FSS is NFS-based, multi-AD accessible, and highly scalable.

Answer

Requires manual OS mounting

Answer

Block-level access

Question 8

Which THREE of the following are components of an OCI Load Balancer?

Accepted Answer

Listeners. In OCI, a Load Balancer is built from listeners, backend sets, and load balancing policies: Listeners (B) define the protocol/port (e.g., HTTP/HTTPS/TCP) on which the load balancer accepts incoming traffic and attach to backend sets, making them a core component. Backend sets (D) are the logical groupings of backend servers (compute instances or IPs) with health-check configuration that receive the balanced traffic. Load balancing policies (E) determine how traffic is distributed across the backends in a backend set (e.g., weighted round robin, least connections, IP hash), so they are also a required component. Security Lists (A) and Route Tables (C) are VCN networking constructs used for subnet-level firewall rules and routing respectively; they are not components of the Load Balancer itself, even though a load balancer's subnet may reference them.

Answer

Security Lists

Answer

Route Tables

Question 9

Which TWO of the following are valid OCI compute shape types?

Accepted Answer

Flexible. In OCI, compute shapes are categorized by their underlying hardware and provisioning model, and 'Flexible' (B) is a valid shape type because flexible shapes let you customize the number of OCPUs and amount of memory within defined limits (for example, VM.Standard.E4.Flex or VM.Standard3.Flex). 'Bare Metal' (E) is also a valid OCI compute shape type, referring to shapes such as BM.Standard.E4.128 that give you the entire physical server with no hypervisor overhead. The other options are not OCI shape types: 'Virtual Disk' (A) describes a storage resource, not a compute shape; 'Dynamic' (C) is not an OCI compute shape category; and 'Container-only' (D) is not a valid OCI compute shape designation, since containers run on compute instances rather than defining a shape type.

Answer

Virtual Disk

Answer

Dynamic

Answer

Container-only

Question 10

Which TWO of the following are OCI storage services?

Accepted Answer

Block Volume. Object Storage and Block Volume are primary OCI storage services.
