• Question 101:

  You are a solution architect working with a startup that has decided to move their workload to Oracle Cloud Infrastructure. Since their workload is small, upon architecting, you decide its sufficient to use 8 compute instances to run their workload. The company wants to use a common storage for their instances. So, you propose the idea of attaching a block volume to multiple instances to provide a common storage.

  Which of the below option is NOT true for such a solution?

  A. If the block volume is already attached to an instance as read/write non-shareable you can't attach it to another instance until you detach it from the first instance.
  B. Block volumes attached as read-only are configured as shareable by default.
  C. You can delete a block volume from one instance without detaching it from all other instances there by keeping other instance's storage intact.
  D. Once you attach a block volume to an instance as read-only, it can only be attached to other instances as read-only.
  C. You can delete a block volume from one instance without detaching it from all other instances there by keeping other instance's storage intact.

• Question 102:

  An online Stock trading application is deployed to multiple Availability Domains in the us phoenix-1 region. Considering the high volume of transactions that the trading application handles, the company has hired you to ensure that the data stored by the application available, and disaster resilient. In the event of failure, the Recovery lime Objective (UK)) must be less than 2 hours to meet regulator requirements.

  Which Disaster Recovery strategy should be used to achieve the RTO requirement In the event of system failure?

  A. Configure hourly block volumes backups through the Storage Gateway service.
  B. Configure hourly block volumes backups using the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI)
  C. Store hourly block volumes backup to NVMe device under a compute instance and generate a custom Image every 5 minutes.
  D. Configure your application to use synchronous master slave data replication between Availability Domains.
  B. Configure hourly block volumes backups using the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI)

  Explanation/Reference:

  You can use the CLI, REST APIs, or the SDKs to automate, script, and manage volume backups and their lifecycle. Planning Your Backup The primary use of backups is to support business continuity, disaster recovery, and long- term archiving requirements. When determining a backup schedule, your backup plan and goals should consider the following: Frequency: How often you want to back up your data. Recovery time: How long you can wait for a backup to be restored and accessible to the applications that use it. The time for a backup to complete varies on several factors, but it will generally take a few minutes or longer, depending on the size of the data being backed up and the amount of data that has changed since your last backup. Number of stored backups: How many backups you need to keep available and the deletion schedule for those you no longer need. You can only create one backup at a time, so if a backup is underway, it will need to complete before you can create another one. For details about the number of backups you can store

  Federating with Microsoft Azure Active Directory

  To federate with Azure AD, you set up Oracle Cloud Infrastructure as a basic SAML single sign-on application in Azure AD. To set up this application, you perform some steps in the Oracle Cloud Infrastructure Console and some steps in

  Azure AD. Following is the general process an administrator goes through to set up the federation. Details for each step are given in the next section. In Oracle Cloud Infrastructure, download the federation metadata document. In Azure AD,

  set up Oracle Cloud Infrastructure Console as an enterprise application. In Azure AD, configure the Oracle Cloud Infrastructure enterprise application for single sign-on.

  In Azure AD, set up the user attributes and claims. In Azure AD, download the Azure AD SAML metadata document. In Azure AD, assign user groups to the application. In Oracle Cloud Infrastructure, set up Azure AD as an identity provider.

  In Oracle Cloud Infrastructure, map your Azure AD groups to Oracle Cloud Infrastructure groups.

  In Oracle Cloud Infrastructure, set up the IAM policies to govern access for your Azure AD groups.

  Share the Oracle Cloud Infrastructure sign-in URL with your user

  E. Contiguous numbers need to be assigned for each part so that Object Storage constructs the object by ordering, part numbers in ascending order
  A. Active multipart upload can be checked by listing all parts that have been uploaded, however It Is not possible to list information for individual object part in an active multipart upload
  D. After initiating a multipart upload by making a CreateMultlPartUpload RESI API Call, the upload remains active until you explicitly commit it or abort.

  ---

  Explanation/Reference:

  You can check on an active multipart upload by listing all parts that have been uploaded. (You cannot list information for an individual object part in an active multipart upload.)

  After you finish creating object parts, initiate a multipart upload by making a CreateMultipartUpload REST API call. Provide the object name and any object metadata. Object Storage responds with a unique upload ID that you must include in any requests related to this multipart upload. Object Storage also marks the upload as active. The upload remains active until you explicitly commit it or abort it.
