• Question 102:

  Which two statements are true about the Oracle Cloud Infrastructure Object Storage Service? (Choose two.)

  A. It provides higher IOPS than Block Storage.
  B. It can be directly attached or detached from a compute instance.
  C. Data is stored redundantly only in a single AD.
  D. Data is stored redundantly across multiple availability domains (ADs) in a multi-AD region.
  E. It provides strong consistency.
  D. Data is stored redundantly across multiple availability domains (ADs) in a multi-AD region.
  E. It provides strong consistency.

  STRONG CONSISTENCY When a read request is made, Object Storage always serves the most recent copy of the data that was written to the system. DURABILITY Object Storage is a regional service. Data is stored redundantly across multiple storage servers. Object Storage actively monitors data integrity using checksums and automatically detects and repairs corrupt data. Object Storage actively monitors and ensures data redundancy. If a redundancy loss is detected, Object Storage automatically creates more data copies. For more details about Object Storage durability, see the Oracle Cloud Infrastructure Object Storage FAQ. CUSTOM METADATA

  You can define your own extensive metadata as key-value pairs for any purpose. For example, you can create descriptive tags for objects, retrieve those tags, and sort through the data. You can assign custom metadata to objects and buckets using the Oracle Cloud Infrastructure CLI or SDK. See Software Development Kits and Command Line Interface for details. ENCRYPTION Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own key. Data encryption keys are encrypted with a master encryption key that is frequently rotated. Encryption is enabled by default and cannot be turned off.

• Question 103:

  Your application front end consists of several Oracle Cloud Infrastructure compute instances behind a public load balancer. You have configured the load balancer to perform health checks on these instances. What will happen if an instance fails to pass the configured health checks?

  A. The instance is replaced automatically by the load balancer.
  B. The instance is terminated automatically by the load balancer.
  C. The instance is taken out of the back end set by the load balancer.
  D. The load balancer stops sending traffic to that instance.
  D. The load balancer stops sending traffic to that instance.

  ---

  One or more of the backend servers reports as unhealthy. A backend server might be unhealthy or the health check might be misconfigured.

• Question 104:

  You have multiple applications installed on a compute instance and these applications generate a large amount of log files. These log files must reside on the boot volume for a minimum of 15 days and must be retained for at least 60 days.

  The 60-day retention requirement is causing an issue with available disk space.

  What are the two recommended methods to provide additional boot volume space for this compute instance? (Choose two.)

  A. Terminate the instance while preserving the boot volume. Create a new instance from the boot volume and select a DenseIO shape to take advantage of local NVMe storage.
  B. Create an object storage bucket and use a script that runs daily to move log files older than 15 days to the bucket.
  C. Create and attach a block volume to the compute instance and copy the log files.
  D. Create a custom image and launch a new compute instance with a larger boot volume size.
  E. Write a custom script to remove the log files on a daily basis and free up the space on the boot volume.
  B. Create an object storage bucket and use a script that runs daily to move log files older than 15 days to the bucket.
  D. Create a custom image and launch a new compute instance with a larger boot volume size.

  ---

  These log files must reside on the boot volume for a minimum of 15 days so you have to increase the boot Volume

• Question 105:

  Which two statements are true about encryption on Oracle Cloud Infrastructure (OCI)? (Choose two.)

  A. By default, object storage and block storage are encrypted at rest.
  B. A customer is responsible for data encryption in all services of OCI.
  C. By default, DB Systems offers an encrypted database.
  D. By default, NVMe drives are encrypted but the block volume service is not.
  A. By default, object storage and block storage are encrypted at rest.
  C. By default, DB Systems offers an encrypted database.

• Question 106:

  Which two statements are true about data guard service on DB Systems in Oracle Cloud Infrastructure (OCI)?

  A. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal.
  B. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database.
  C. Data guard configuration on the OCI is limited to a virtual machine only.
  D. Both DB Systems must use the same VCN, and port 1521 must be open.
  B. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database.
  D. Both DB Systems must use the same VCN, and port 1521 must be open.

• Question 107:

  Which statement is true about Oracle Cloud Identifiers (OCID)?

  A. mytenancy.oc.ocid is a valid OCID.
  B. If you delete a user, and them create a new user with the same name, the user will be considered a different user because of different OCIDs.
  C. Users can customize OCIDs for all the resources in their compartments.
  D. If you delete a user, and then create a new user with the same name, the new user will be assigned the exact same OCIDs as the system remembers.
  B. If you delete a user, and them create a new user with the same name, the user will be considered a different user because of different OCIDs.

• Question 108:

  You create a public Load Balancer instance and configure a back end set "BES1" with one back end server running a service on port 80. You also create a listener on port 80 and configure that listener to use the back end set "BES1". A client

  makes one HTTP request to the Load Balancer with the correct protocol and port.

  How many connections does the Load Balancer maintain?

  A. 1
  B. 2
  C. 4
  D. 3
  B. 2

• Question 109:

  Which statement is true about a pre-authenticated request in Oracle Cloud Infrastructure Object Storage?

  A. You can create only 1, 000 pre-authenticated requests per bucket.
  B. You can create a pre-authenticated request only for public buckets.
  C. You cannot retire a pre-authenticated request before it expires.
  D. You cannot extend the expiration date on a pre-authenticated request.
  D. You cannot extend the expiration date on a pre-authenticated request.

  ---

  https://docs.cloud.oracle.com/iaas/Content/Object/Tasks/usingpreauthenticatedrequests.htm You can create an unlimited number of pre-authenticated requests. You can't edit a pre-authenticated request. If you want to change user access options in response to changing requirements, you must create a new pre-authenticated request. URL: https://docs.cloud.oracle.com/iaas/Content/Object/Tasks/managingbuckets.htm You can change a bucket's access from public to private or from private to public. Changing the type of access doesn't affect existing pre-authenticated requests. Existing pre-authenticated requests still work.

  A. subnet
  B. Availability Domain
  C. Virtual Cloud Network
  D. host name
  E. instance shape
  F. image operating system
  G. private IP address
  A. subnet
  B. Availability Domain
  C. Virtual Cloud Network
  E. instance shape
  F. image operating system
