Question 1

Multiple choice

Which two statements are true about adding secondary VNICs to an existing compute instance? (Choose two.)

The primary and secondary VNIC association must be in the same availability domain

You can assign an Ephemeral Public IP to a secondary VNIC

You can remove the primary VNIC after the secondary VNIC's attachment is complete

The primary and secondary VNIC association can be in different virtual cloud networks (VCNs)

Question 2

Single choice

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?

The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443.

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.

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.

The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.

Question 3

Single choice

You are designing a shared storage solution for your company in Oracle Cloud Infrastructure. The proposed storage solution should allow users to create a hierarchical structure (similar to the directory structure in Linux or Windows based systems). The solution should provide data encryption and a large amount of storage space.

Which would be the best implementation strategy?

Use block storage. Create and attach a large block storage volume to one compute instance. Assign a public IP to the compute instance. Store data on the block storage and access it by connecting to the compute instance.

Use object storage. Create a single namespace and multiple buckets to create the hierarchical directory structure.

Use object storage. Create multiple namespaces with one bucket each. Make the buckets publicly accessible.

Use file storage service. Create a file system and a mount target. Share the private IP of the mount

target.

Question 4

Single choice

Which statement is true about cloning a volume?

You need to detach a volume before cloning from it.

A cloned volume is the same as a snapshot that has a dependency on the source volume.

You can change the block volume size when cloning a volume.

You can create a clone for a volume across regions.

Question 5

Single choice

You have two NFS clients running in two different subnets within the same Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN). You have created a shared file system for the two NFS clients who want to connect to the same file system, but you want to restrict one of the clients to have READ access while the other has READ/Write access.

Which OCr feature would you leverage to meet this requirement?

Use VCN security rules to control access for the NFS clients

B. Use OCI Identity Access Management to control access for the NFS clients

C. Use File Storage NFS Export Options to control access for the NFS clients

Use NFS security to control access for the NES clients

Correct answer: C

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).

EXPORT

Exports control how NFS clients access file systems when they connect to a mount target. File systems are exported (made available) through mount targets. Each mount target maintains an export set which contains one or many exports. A file system must have at least one export in one mount target in order for instances to mount the file system. The information used by an export includes the file system OCID, mount target OCID, export set OCID, export path, and client export options. For more information, see Managing Mount Targets.

EXPORT SET

Collection of one or more exports that control what file systems the mount target exports using NFSv3 protocol and how those file systems are found using the NFS mount protocol. Each mount target has an export set. Each file system associated with the mount target has at least one export in the export set.

EXPORT PATH

A path that is specified when an export is created. It uniquely identifies the file system within the mount target, letting you associate up to 100 file systems to a single mount target. This path is unrelated to any path within the file system itself, or the client mount point path.

EXPORT OPTIONS

NFS export options are a set of parameters within the export that specify the level of access granted to NFS clients when they connect to a mount target. An NFS export options entry within an export defines access for a single IP address or CIDR block range. For more information, see Working with NFS Export Options.

Question 6

Single choice

You have a shared file system between two web servers using File Storage Service (FSS) and you were tasked to create a backup plan for this environment to protect the data placed into the shared file system.

What is the recommended approach to create this backup using FSS features?

Implement a backup policy to execute a snapshot of the shared volume.

Implement a backup policy to copy data from the shared volume to object storage.

Compress the data that is in the shared volume and copy it into a different folder on the boot volume disk.

Use the rsync tool to send data from the shared volume to a boot volume disk.

Use the rsync tool to send data from the shared volume to a block volume.

Question 7

Multiple choice

Which two statements are true about subnets within a VCN? (Choose two.)

You can have multiple subnets in an Availability Domain for a given VCN.

Private and Public subnets cannot reside in the same Availability Domain for a given VCN.

Subnets can have their IP addresses overlap with other subnets in another network for a given VCN.

Instances obtain their private IP and the associated security list from their subnets.

Question 8

Single choice

You have an instance running in a development compartment that needs to make API calls against other OCI services, but you do not want to configure user credentials or a store a configuration file on the instance.

How can you meet this requirement?

Create a dynamic group with matching rules to include your instance

B. Instances can automatically make calls to other OCI services

C. Instances are secure and cannot make calls to other OCI services

D. Create a dynamic group with matching rules to include your instance and write a policy for this
dynamic group

Question 9

Multiple choice

Which two statements are true regarding cloning a block volume?

You can change the block volume performance when creating a clone

You can clone block volumes across regions

C. You can change the block volume size when creating a clone

D. You can skip block volume encryption when creating a clone

Question 10

Single choice

Which storage would you use if your big data workload requires shared access and an NFS based interface?

File Storage

Storage Software Cloud Appliance

Object Storage

Archive Storage

Block Volume
