You developed a microservices based application that runs on Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). You want to provide access to this cluster to other team members. What should you do to provide access to this cluster using as fewest steps as possible?
A. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Other team members should use OCI Cloud Shell to generate the kubeconfig into their own cloud shell environment and access the cluster using kubectl from cloud shell. B. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Create individual users and access token for each team member. Other team members should use OCI Cloud Shell to generate the kubeconfig into their own cloud shell environment and access the cluster using kubectl from cloud shell. C. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Create a cluster role and cluster role binding to provide access to the cluster for each team member. Other team members should install oci cli and kubectl locally on their laptop. Use the oci cli to generate the kubeconfig and use kubectl to access the cluster. D. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Other team members should install oci cli and kubectl locally on their laptop. Use the oci cli to generate the kubeconfig and use kubectl to access the cluster.
B. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Create individual users and access token for each team member. Other team members should use OCI Cloud Shell to generate the kubeconfig into their own cloud shell environment and access the cluster using kubectl from cloud shell.
Question 72:

A. By default, object storage and block storage are encrypted at rest. C. By default, DB Systems offers an encrypted database.
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 74:
Which statement is NOT true about the Oracle Cloud Infrastructure Object Storage service?
A. Object storage resources can be shared across tenancies. B. Immutable option for data stored in the Object Storage can be set via retention rules. C. Object versioning is enabled at namespace level. D. Object lifecycle rules can be used to either archive or delete objects.
B. Immutable option for data stored in the Object Storage can be set via retention rules.
Which two features are offered natively on Oracle Cloud Infrastructure Database Cloud Service (DBCS)? (Choose two.)
A. Data Guard in Async mode within a region B. GoldenGate replication between two regions C. Data Guard in Maximum Protection mode D. backup to Object Storage
A. Data Guard in Async mode within a region D. backup to Object Storage
Data Guard in Maximum Performance protection mode is supported not simply Maximum Protection mode, however, you can configure additional protection modes and transport types by logging on to the DB system and accessing Data Guard command-line interface( DGMGRL).
Question 76:
You are tasked with creating a highly available clustered application on Oracle Cloud Infrastructure consisting of three nodes. The round-trip latency between nodes must be less than 500 祍 (micro- seconds) and your cluster should be
resilient to hardware failure.
What is the recommended deployment strategy?
A. Deploy the cluster nodes in a single region and deploy each node into a different AD. Select the same fault domain in each AD to ensure consistency. B. Deploy the cluster nodes in two separate regions and take advantage of multiple availability domains (ADs) in each region. C. Deploy the cluster nodes in a single region and deploy each node into a different AD. D. Deploy the cluster nodes in a single region and deploy each node in different fault domains within a single AD.
D. Deploy the cluster nodes in a single region and deploy each node in different fault domains within a single AD.
Question 77:
Which three types of credentials are used to manage Oracle Cloud Infrastructure Identity and Access Management (IAM)? (Choose three.)
A. Windows Password B. API Signing Key C. Swift Password D. SSH Key E. Console Password
B. API Signing Key C. Swift Password E. Console Password
References: https://cloud.oracle.com/iaas/whitepapers/best-practices-for-iam-on-oci.pdf You manage the following types of credentials with Oracle Cloud Infrastructure IAM: Console password: For signing in to the Console, which is the user interface for interacting with Oracle Cloud Infrastructure API signing key (in PEM format): For sending API requests, which require authentication Swift password: For using a Swift client with Recovery Manager (RMAN) to back up an Oracle Database System (DB System) database to Object Storage
Question 78:
When you try to create an instance on Oracle Cloud Infrastructure (OCI), what are three valid sources to choose the image from?
A. Dedicated VM Host B. Object Storage C. Bare Metal Instance D. Platform Images E. Custom Image F. Partner Images G. Instance Pools
D. Platform Images E. Custom Image F. Partner Images
Which two statements below are correct with respect to adding secondary Virtual Network Interface Cards (VNICs) to an existing compute instance in Oracle Cloud Infrastructure? (Choose two.)
A. The secondary VNIC is required to be in the same Virtual Cloud Network (VCN), but can be in different subnet, as the primary VNIC. B. The primary and secondary VNIC association can be in different virtual cloud networks (VCNs). C. You cannot assign an Ephemeral Public IP to a secondary VNIC. D. The primary and secondary VNIC association must be in the same availability domain. E. You can remove the primary VNIC after the secondary VNIC's attachment is complete.
B. The primary and secondary VNIC association can be in different virtual cloud networks (VCNs). D. The primary and secondary VNIC association must be in the same availability domain.
"You can add secondary VNICs to an instance after it's launched. Each secondary VNIC can be in a subnet in the same VCN as the primary VNIC, or in a different subnet that is either in the same VCN or a different one. However, all the VNICs must be in the same availability domain as the instance." https://docs.cloud.oracle.com/en-us/iaas/Content/Network/Tasks/managingVNICs.htm
Question 80:
You deployed an Oracle Cloud Infrastructure (OCI) compute instance (VM.Standard2.16) to run a SQL database. After a few weeks, you need to increase disk performance by using NVMe disks but keeping the same number of CPUs. As a
first step, you terminate the instance and preserve the boot volume.
What is the next step?
A. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume and move the SQL Database data to block volume B. Create a new instance using a VM.DenseIO2.8 shape using the preserved boot volume and move the SQL Database data to NVMe disks C. Create a new instance using a VM.Standard1.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks D. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume move the SQL Database data to NVMe disks
D. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume move the SQL Database data to NVMe disks
to Increase disk performance by using NVMe disks you can use Dense IO Shape also as the number of CPUs will not change so we should VM.DenseIO2.16
