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

• Question 81:

  Which service is the most effective for moving large amounts of data from your on-premises to OCI?

  A. Data Transfer appliance

  B. Data Safe

  C. Internal Gateway

  D. Dynamic Routing Gateway

  Correct Answer: A

• Question 82:

  Which capability can be used to protect against unexpected hardware or power supply failures within an availability domain?

  A. Fault Domains

  B. Compartments

  C. Top of Rack Switches

  D. Power Distribution Units

  Correct Answer: A

  A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are

  not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical

  hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains.

  Usually fault domains to do the following things:

  1) Protect against unexpected hardware failures or power supply failures.

  2) Protect against planned outages because of Compute hardware maintenance.

• Question 84:

  A banking platform has been re-designed to a microservices based architecture using Docker containers for deployment. Which service can you use to deploy containers on Oracle Cloud Infrastructure (OCI)?

  A. Container Engine for Kubernetes (OKE)

  B. Streaming Service

  C. API Gateway

  D. File Storage Service

  Correct Answer: A

  Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy. Container Engine for Kubernetes uses Kubernetes - the open-source system for automating deployment, scaling, and management of containerized applications across clusters of hosts. Kubernetes groups the containers that make up an application into logical units (called pods) for easy management and discovery. You can access Container Engine for Kubernetes to define and create Kubernetes clusters using the Console and the REST API. You can access the clusters you create using the Kubernetes command line (kubectl), the Kubernetes Dashboard, and the Kubernetes API. Container Engine for Kubernetes is integrated with Oracle Cloud Infrastructure Identity and Access Management (IAM), which provides easy authentication with native Oracle Cloud Infrastructure identity functionality.

• Question 85:

  You are setting up a proof of concept (POC) and need to quickly establish a secure between an on- premises data center and Oracle Cloud Infrastructure (OCI). Which OCI service should you implement?

  A. VCN Peering

  B. FastConnect

  C. Internet Gateway

  D. IPSec VPN

  Correct Answer: D

  You can set up a single IPSec VPN with a simple layout that you might use for a proof of concept (POC).

  Reference:

  https://docs.cloud.oracle.com/en-us/iaas/Content/Network/Tasks/settingupIPsec.htm

  It is possible to set up a site-to-site Virtual Private Network (VPN) Connection between your on- premises network (a data center or corporate LAN) and your Oracle virtual cloud network (VCN) over a secure encrypted VPN. The VPN

  connection uses industry-standard IPSec protocols. The Oracle service that provides site-to-site connectivity is named VPN Connect (also referred to as an IPSec VPN).

• Question 86:

  Which OCI Identity and access management capability helps you to organize multiple users into teams?

  A. Policies

  B. Groups

  C. Dynamic Groups

  D. Users

  Correct Answer: B

  IAM Group is A collection of users who all need the same type of access to a particular set of resources or compartment.

  IAM DYNAMIC GROUP is A special type of group that contains resources (such as compute instances) that match rules that you define (thus the membership can change dynamically as matching resources are created or deleted). These

  instances act as "principal" actors and can make API calls to services according to policies that you write for the dynamic group.

  Reference:

  https://docs.cloud.oracle.com/en-us/iaas/Content/Identity/Concepts/overview.htm GROUP:

  A collection of users who all need the same type of access to a particular set of resources or compartment.

• Question 87:

  OCI budgets can be set on which two options?

  A. Cost-tracking tags

  B. Free-form tags

  C. Compartments

  D. Virtual Cloud Network

  E. Tenancy

  Correct Answer: AC

  In OCI a budget can be used to set soft limits on your Oracle Cloud Infrastructure spending. You can set alerts on your budget to let you know when you might exceed your budget, and you can view all of your budgets and spending from one single place in the Oracle Cloud Infrastructure console. Budgets are set on

  1.

  Cost-tracking tags

  2.

  Compartments (including the root compartment)

• Question 89:

  Which Oracle Cloud Infrastructure (OCI) service is best suited for running serverless apps?

  A. Oracle Functions

  B. Virtual Cloud Network

  C. Streaming

  D. Audit

  Correct Answer: A

  Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a- Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs. The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution. Oracle Functions is based on Fn Project. Fn Project is an open source, container native, serverless platform that can be run anywhere - any cloud or on-premises. Fn Project is easy to use, extensible, and performant. You can download and install the open source distribution of Fn Project, develop and test a function locally, and then use the same tooling to deploy that function to Oracle Functions. You can access Oracle Functions using the Console, a CLI, and a REST API. You can invoke the functions you deploy to Oracle Functions using the CLI or by making signed HTTP requests.

• Question 90:

  What does compute instance horizonal scaling mean?

  A. stopping/starting the instance

  B. backing up data to object storage

  C. adding additional compute instances

  D. changing compute instance size

  Correct Answer: C

  Cloud Horizontal Scaling refers to provisioning additional servers to meet your needs, often splitting workloads between servers to limit the number of requests any individual server is getting. In a cloud-based environment, this would mean

  adding additional instances instead of moving to a larger instance size.

  Cloud Vertical Scaling refers to adding more CPU or memory to an existing server, or replacing one server with a more powerful server.

  Reference:

  https://cloudcheckr.com/cloud-cost-management/cloud-vs-data-center-what-is-scalability-in-cloud- computing/

  Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine. An easy way to remember this is to

  think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.

  

  With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool -- Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and

  comes with an upper limit.
