• Question 123:

  You need to create a high performance shared file system, and have been advised to use file storage service (FSS). You have logged into the Oracle Cloud Infrastructure console, created a file system, and followed the steps to mount the

  shared file system on your Linux instance. However, you are still unable to access the shared file system from your Linux instance.

  What is the likely reason for this?

  A. There are no security list rules for mount target traffic
  B. There is no internet gateway (IGW) set up for mount target traffic
  C. There is no Identity and Access Management (IAM) policies set up to allow you to access the mount target
  D. There is no route in your virtual cloud network's (VCN) route table for mount target traffic
  A. There are no security list rules for mount target traffic

  ---

  Virtual firewall rules for your VCN. Your VCN comes with a default security list, and you can add more. These security lists provide ingress and egress rules that specify the types of traffic allowed in and out of the instances. You can choose whether a given rule is stateful or stateless. Security list rules must be set up so that clients can connect to file system mount targets. For more information about how security lists work in Oracle Cloud Infrastructure, see Security Lists in the Networking documentation. For information about setting up specific security list rules required for mount target traffic, see Configuring VCN Security List Rules for File Storage. About Security explains how security lists interact with other types of security in your file system. https://docs.cloud.oracle.com/iaas/Content/File/Concepts/filestorageoverview.htm

• Question 124:

  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 125:

  Which scaling option does Database Cloud Service (DBCS) on Bare Metal Shape offer?

  A. network bandwidth
  B. CPU
  C. storage
  D. memory
  B. CPU

• Question 126:

  Which two statements are true about Oracle Cloud Infrastructure storage services?

  A. You can move Object Storage buckets, Block Volumes and File Storage mount targets between compartments.
  B. File storage mount target does not provide a private IP address, while the Object Storage bucket provides one.
  C. File Storage uses the network file system (NFS) protocol, whereas Block Volume uses ISCSI.
  D. Block Volume service scales to Exabytes per Instance, while File Storage service offers unlimited scalability.
  E. You can take Incremental snapshots of Block Volumes, File Storage file systems and Object Storage buckets.
  A. You can move Object Storage buckets, Block Volumes and File Storage mount targets between compartments.
  C. File Storage uses the network file system (NFS) protocol, whereas Block Volume uses ISCSI.

• Question 127:

  You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet

  and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with

  the database service. However, when you type the URL of this student registration application in your browser, no web page appears.

  What could be the cause?

  A. The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443.
  B. The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.
  C. The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set.
  D. The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.
  A. The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443.

• Question 128:

  You want an Oracle Cloud Infrastructure (OCI) compute instance in your compartment to make API calls to other services within OCI without storing credentials in a configuration file. What do you need to do?

  A. Create a dynamic group with appropriate matching rules to include the instance, and reference this group in your IAM policy statement
  B. Instances cannot access services outside their compartment
  C. VM instances are treated as users. Create a user, assign the user to that VM instance, and reference the instance in your Identity and Access Management (IAM) policy statement
  D. By default, all VM instances are created with an instance principal. Reference this instance principal in your IAM policy statement
  A. Create a dynamic group with appropriate matching rules to include the instance, and reference this group in your IAM policy statement

• Question 129:

  Which DNS resource record type is used to point a host name to an IPv4 address?

  A. ALIAS
  B. A
  C. CNAME
  D. AAAA
  B. A

• Question 130:

  A company currently uses Microsoft Active Directory as its identity provider. The company recently subscribed to Oracle Cloud Infrastructure (OCI) to leverage the cloud platform for test and development. As the administrator, you configured

  the OCI tenancy to be federated with Microsoft Active Directory. Now you need to give access to developers so that they can start creating resources in their OCI accounts.

  Which step will you perform to make sure you are not duplicating user creation inside of OCI tenancy?

  A. Create a group for developers on OCI and map the group to a similar group in Microsoft Active Directory during the federation process.
  B. Create a new user account in OCI for each user, and then create policies to provide access to developers.
  C. Create a group for developers on OCI, export all the developers from Microsoft Active Directory, and then import them into the Identity and Access Management (IAM) group.
  D. Create a single user account in OCI, and then create policies to provide access to developers to this single account.
  A. Create a group for developers on OCI and map the group to a similar group in Microsoft Active Directory during the federation process.

  When working with your IdP, your administrator defines groups and assigns each user to one or more groups according to the type of access the user needs. Oracle Cloud Infrastructure also uses the concept of groups (in conjunction with IAM policies) to define the type of access a user has. As part of setting up the relationship with the IdP, your administrator can map each IdP group to a similarly defined IAM group, so that your company can re-use the IdP group definitions when authorizing user access to Oracle Cloud Infrastructure resources.
