Oracle Oracle Certifications 1Z0-1085-24 Questions & Answers

• Question 101:

  What is an availability domain in Oracle Cloud Infrastructure?

  A. A set of virtual cloud networks

  B. A localized geographical area

  C. A type of encrypted traffic

  D. One or more data centers located within a region

  Correct Answer: D

  An availability domain in Oracle Cloud Infrastructure refers to one or more data centers located within a region. Each availability domain is isolated from the others, with its own power, cooling, and networking to ensure fault tolerance and reliability.

• Question 102:

  Which statement is NOT true about compartments in Oracle Cloud Infrastructure?

  A. Compartments are a global resource.

  B. Identity and Access Management (IAM) policies can be written to grant access to resources in specific compartments.

  C. Compartments provide a way to store and manage encryption keys and secrets.

  D. Compartments can be nested to create a hierarchy.

  Correct Answer: C

  This statement is NOT true. Compartments in Oracle Cloud Infrastructure do not provide a way to store and manage encryption keys and secrets. This functionality is typically handled by other services such as Key Management.

• Question 103:

  Which networking component of OCI Virtual Cloud Network provides compute instances in a private subnet with outbound Internet access?

  A. Network Address Translation (NAT)

  B. Service Gateway

  C. Dynamic Routing Gateway (DRG)

  D. Internet Gateway

  Correct Answer: A

  Network Address Translation (NAT) allows compute instances in a private subnet to access the Internet while keeping their private IP addresses hidden. It provides outbound Internet access for instances in a private subnet by translating their private IP addresses to a public IP address.

• Question 104:

  Which performance level is NOT available in the Oracle Cloud Infrastructure Block Volume service?

  A. Balanced

  B. Higher Performance

  C. Ultra High Performance

  D. Low Performance

  Correct Answer: D

  The Low Performance level is NOT available in the Oracle Cloud Infrastructure Block Volume service. This option does not exist as a performance level for block volumes in OCI.

• Question 105:

  What is the primary purpose of the MySQL Database Service HeatWave configuration in OCI?

  A. To enable seamless database migration from on-premises to OCI

  B. To provide a distributed in-memory query accelerator

  C. To offer a serverless MySQL deployment

  D. To ensure high availability and fault tolerance

  Correct Answer: B

  MySQL Database Service HeatWave is designed to accelerate query performance by offloading analytics to an in-memory columnar store. It enables faster query execution for analytical workloads.

• Question 106:

  Which type of workload is NOT suitable for using the Oracle Cloud Infrastructure File Storage service?

  A. Big data and analytics

  B. Media processing

  C. Content management

  D. Running small personal websites

  Correct Answer: D

  Running small personal websites typically do not require the scalability and performance capabilities provided by Oracle Cloud Infrastructure File Storage service. It may be more cost-effective and efficient to use other storage solutions for such workloads.

• Question 107:

  Which feature does the Oracle Cloud Infrastructure Compute service leverage for ensuring high availability of applications?

  A. Fault Domains

  B. Real Application Clusters (RAC)

  C. Golden Gate

  D. Data Guard

  Correct Answer: A

  Fault domains in Oracle Cloud Infrastructure are used to distribute instances across different physical hardware within an availability domain. This helps in ensuring high availability and fault tolerance by reducing the impact of hardware failures on instances.

• Question 108:

  Which of the following is NOT a use case suitable for OCI Container Instances?

  A. Running APIs and web applications

  B. Performing automation tasks for cloud operations

  C. Running containerized apps on Kubernetes

  D. Running data and media processing jobs

  Correct Answer: C

  OCI Container Instances are designed for simpler workloads, whereas running containerized apps at scale on Kubernetes requires a container orchestration platform, which is a different use case.

• Question 109:

  Which is NOT a type of instance offered by the Oracle Cloud Infrastructure Compute service?

  A. Virtual Machine

  B. Bare Metal

  C. Dedicated Virtual Machine Host

  D. Nano instance

  Correct Answer: D

  Nano instances are not offered by OCI. The compute service provides other instance types like Virtual Machines, Bare Metal, and Dedicated Hosts but does not include Nano instances.

• Question 110:

  Which component of the Oracle Cloud Infrastructure Networking service provides a private connection between a VCN and an on-premises network?

  A. Network Address Translation (NAT)

  B. Dynamic Routing Gateway (DRG)

  C. Internet Gateway

  D. Service Gateway

  Correct Answer: B

  Dynamic Routing Gateway (DRG) is the component of Oracle Cloud Infrastructure Networking service that provides a private connection between a VCN and an on-premises network using VPN or FastConnect. It allows secure communication between the cloud and on-premises resources.
