these instances on a regular basis? (Choose the best answer.)

B. oci compute instance launch – –generate–cli–skeleton
C. oci compute provision–instance – –generate–full–command–JSON–input
D. oci compute instance launch – –generate–full–command–JSON–input

QUESTION 3

You are using the Oracle Cloud Infrastructure Command Line Interface to launch a Linux virtual machine. You enter the
following command (with correct values for all parameters): The command fails.

Which is NOT a valid parameter in this command? (Choose the best answer.)
A. –t
B. – –image-id
C. – –shape “andlt;shape_name>”
D. –c
E. – –subnet-id

QUESTION 4

You have set an alarm to be generated when the CPU usage of a specified instance is greater than 10%. In the alarm
behavior view below you notice that the critical condition happened around 23:30. You were expecting a notification
after 1 minute, however, the alarm firing state did not begin until 23:33.

What should you change to fix it? (Choose the best answer.)

A. Change the alarm\’s metric interval to 1.
B. Change the alarm condition to be greater than 3%.
C. Change the notification topic that you previously associated with the alarm.
D. Change the alarm\’s trigger delay minutes value to 1.

QUESTION 5

You run a large global application with 90% of customers based in the US and Canada. You want to be able to test a
new feature and allow a small percentage of users to access the new version of your application.
What Oracle Cloud Infrastructure Traffic Management steering policy should you utilize? (Choose the best answer.)

A. Load Balancer
B. IP Prefix steering
C. ASN steering
D. Geolocation steering

QUESTION 6

Which option contains the essential components of the Oracle Cloud Infrastructure Notifications service? (Choose the
best answer.)

A. An ALARM with a name unique across the tenancy, a SUBSCRIPTION, and a METRIC with the measurement of
interest.

B. A TOPIC with a name unique across the tenancy, a SUBSCRIPTION, and a MESSAGE where content is published.

C. A TOPIC with a name unique across the compartment, a SUBSCRIPTION, and a MESSAGE where content is
published.

D. An ALARM with a name unique across the compartment, a SUBSCRIPTION, and a METRIC with the measurement

A. Use OCI CLI profiles to create multiple sets of credentials in your config file, and reference the appropriate profile at
runtime.

B. Create environment variables for the sets of credentials that align to each combination of tenancy, region, and
environment.

C. Run our setup config to create new credentials for each environment every time you want to access the environment.

D. Use different bash terminals for each environment.

QUESTION 8

Which two statements are TRUE about Object Storage data security and encryption in Oracle Cloud Infrastructure
(OCI)? (Choose two.)

A. Client-side encryption is managed by the customer.
B. Data needs to be decrypted on the client-side before retrieving it.
C. OCI Vault Management is used by default to provide data security.
D. All traffic to and from the Object Storage service is encrypted using TLS.
E. A VPN connection to OCI is required to ensure secure data transfer to an object storage bucket.

QUESTION 11

You set up a bastion host in your VCN to only allow your IP address (140.19.2.140) to establish SSH connections to
your Compute Instances that are deployed in a private subnet. The Compute Instances have an attached Network
Security Group with a Source Type: Network Security Group (NSG), Source NSG: NSG-050504. To secure the bastion
host, you added the following ingress rules to its Network Security Group:

However, after checking the bastion host logs, you discovered that there are IP addresses other than your own that can
access your bastion host.

What is the root cause of this issue? (Choose the best answer.)

A. The Security List allows access to all IP addresses which overrides the Network Security Group ingress rules.

C. port 22 provides unrestricted access to 140.19.2.140 and to other IP addresses.
D. A netmask of /32 allows all IP addresses in the 140.19.2.0 network, other than your IP 140.19.2.140

QUESTION 12

Your company recently adopted a hybrid cloud architecture which requires them to migrate some of their on-premises
web applications to Oracle Cloud Infrastructure (OCI). You created a Terraform template that automatically provisions
OCI resources such as compute instances, load balancer, and a database instance. After running the stack using the
terraform apply command, it successfully launched the compute instances and the load balancer, but it failed to create a new database instance with the following error:

Service error: NotAuthorizedOrNotFound. shape VM.Standard2.4 was not found. HTTP status code: 404
You discovered that the resource quotas assigned to your compartment prevent you from using VM.Standard2.4
instance shapes available in your tenancy.

best answer.)

A. Paravirtualized volumes may reduce the maximum IOPS performance for larger block volumes.
B. Paravirtualized is required to manage iSCSI configuration for virtual machine instances.
