Oracle Oracle Certifications 1Z0-1085-20 Questions & Answers

• Question 81:

  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 82:

  Which OCI service is the most cost-effective?

  A. File Storage

  B. Object Storage (standard)

  C. Block Volume

  D. Archive Storage

  Correct Answer: B

• Question 83:

  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 84:

  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 85:

  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 86:

  What is the frequency of OCI usage report generation?

  A. Weekly

  B. Monthly

  C. Annually

  D. Daily

  Correct Answer: D

  A usage report is a comma-separated value (CSV) file that can be used to get a detailed breakdown of resources in Oracle Cloud Infrastructure for audit or invoice reconciliation. The usage report is automatically generated daily, and is stored in an Oracle-owned Object Storage bucket. It contains one row per each Oracle Cloud Infrastructure resource (such as instance, Object Storage bucket, VNIC) per hour along with consumption information, metadata, and tags. Usage reports generally contain 24 hours of usage data, although occasionally a usage report may contain late-arriving data that is older than 24 hours. Usage reports are retained for one year.

• Question 87:

  you are analyzing your Oracle Cloud Infrastructure (OCI) usage with Cost Analysis tool in OCI Console. Which is not a default feature of the tool?

  A. Filter costs by applications

  B. Filter costs by compartments

  C. Filter costs by tags

  D. Filter costs by date

  Correct Answer: A

  You can filter Costs Analysis Tools by following three ways To filter costs by dates To filter costs by tags To filter costs by compartments

• Question 88:

  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 89:

  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

  Cost-tracking tags

  2.

  Compartments (including the root compartment)

• 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-cloudcomputing/ 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.
