NEW QUESTION # 81
Which OCI Identity and access management capability helps you to organize multiple users into teams?
- A. Dynamic Groups
- B. Users
- C. Groups
- D. Policies
Answer: C
Explanation:
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.

Which Is VALID regarding the Oracle Cloud Infrastructure (OCI) Logging service encryption?
- A. OCI logs are not encrypted in-flight.
- B. OCI logs are encrypted when they are archived.
- C. OCI logs are not encrypted while in storage.
- D. OCI logs are not encrypted with disk-level encryption.
Answer: B
Explanation:
OCI logs are encrypted in three ways: in-flight, disk-level, and archive. OCI logs are encrypted in-flight, that is, while they are in the process of being ingested into OCI Logging; after the logs are in the system, they are encrypted with disk-level encryption for commercial environments; and logs are also encrypted when they are archived, and while in storage

Explanation:
Block storage is the primary type of storage used for storing the boot volume of an instance in the Oracle Cloud Infrastructure Compute service. A boot volume is a detachable block storage device that contains the operating system and other software required to boot an instance.
NEW QUESTION # 84
A customer wants to use Oracle Cloud Infrastructure (OCI) storing application backups which can be stored for months, but retrieved immediately based on business needs. Which OCI storage service can be used to meet this requirement?
- A. Archive Storage
- B. Object Storage (standard)
- C. Block Volume
- D. File Storage
Answer: B
Explanation:
Oracle Cloud Infrastructure offers two distinct storage class tiers to address the need for both performant, frequently accessed "hot" storage, and less frequently accessed "cold" storage. Storage tiers help you maximize performance where appropriate and minimize costs where possible.
Use Object Storage for data to which you need fast, immediate, and frequent access. Data accessibility and performance justifies a higher price to store data in the Object Storage tier.
Use Archive Storage for data to which you seldom or rarely access, but that must be retained and preserved for long periods of time. The cost efficiency of the Archive Storage tier offsets the long lead time required to access the data.
Unlike Object Storage, Archive Storage data retrieval is not instantaneous.

Which of these Is defined as a qualifier used for filtering group metric data presented in the Oracle Cloud Infrastructure (OCI) Monitoring service? ^
- A. Dimensions
- B. Namespaces
- C. Facts
- D. Indicators
Answer: A
Explanation:
Dimensions are defined as qualifiers used for filtering group metric data presented in the OCI Monitoring service. Dimensions are key-value pairs that provide additional information about a metric, such as resource ID, region, availability domain, fault domain, shape, image, etc. Dimensions allow you to narrow down the scope of your metric queries and alarms by specifying which resources or attributes you want to monitor. For example, you can use dimensions to filter the CPU utilization metric by instance ID or shape.

NEW QUESTION # 90
Which Oracle cloud infrastructure capability can be used to protect against power failures within an availability Domain?
- A. Services Cells
- B. Data Plane
- C. Fault Domains
- D. Top of Rack Switch
Answer: C
Explanation:
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.
To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time. If you don't specify the fault domain, the system selects one for you. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement across different fault domains, while optimizing for available capacity in the availability domain. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain.
Use fault domains to do the following things:
Protect against unexpected hardware failures or power supply failures.
Protect against planned outages because of Compute hardware maintenance.

NEW QUESTION # 93
You have an application that requires a shared file system. Which of the following services would you use?
- A. Archive Storage
- B. Block Volume
- C. File Storage
- D. Object Storage
Answer: C
Explanation:
Explanation
Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN).
Large Compute clusters of thousands of instances can use the File Storage service for high-performance shared storage. Storage provisioning is fully managed and automatic as your use scales from a single byte to exabytes without upfront provisioning.
The File Storage service supports the Network File System version 3.0 (NFSv3) protocol. The service supports the Network Lock Manager (NLM) protocol for file locking functionality.
Oracle Cloud Infrastructure File Storage employs 5-way replicated storage, located in different fault domains, to provide redundancy for resilient data protection. Data is protected with erasure encoding.
The File Storage service uses the "eventual overwrite" method of data eradication. Files are created in the file system with a unique encryption key. When you delete a single file, its associated encryption key is eradicated, making the file inaccessible. When you delete an entire file system, the file system is marked as inaccessible. The service systematically traverses deleted files and file systems, frees all the used space, and eradicates all residual files.
Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)-compliant file system access semantics and concurrently accessible storage. The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases, including the following:

NEW QUESTION # 95
Which feature allows you to group and logically isolate your Oracle Cloud Infrastructure (OCI) resources?
- A. Compartments
- B. Tenancy
- C. Identity and Access Management Groups
- D. Availability Domains
Answer: A
Explanation:
It is collection of related resources. Compartments are a fundamental component of Oracle Cloud Infrastructure for organizing and isolating your cloud resources. You use them to clearly separate resources for the purposes of measuring usage and billing, access (through the use of IAM Service policies), and isolation (separating the resources for one project or business unit from another). A common approach is to create a compartment for each major part of your organization. For more information, see Overview of the IAM Service and also Setting Up Your Tenancy.
To place a resource in a compartment, simply specify the compartment ID in the "Create" request object when initially creating the resource. For example, to launch an instance into a particular compartment, specify that compartment's OCID in the LaunchInstance request. You can't move an existing resource from one compartment to another.
To use any of the API operations, you must be authorized in an IAM policy. If you're not authorized, talk to an administrator. If you're an administrator who needs to write policies to give users access, see Getting Started with Policies.
NEW QUESTION # 96
Which component of the Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) service can be used for controlling access to resources for authenticated principals?

- C. Group
- D. Compartment
Answer: B
Explanation:
Policies are the component of the OCI IAM service that can be used for controlling access to resources for authenticated principals. A policy is a document that specifies who can access which resources, and how2.
