NEW QUESTION # 51
You are building a container image and pushing it to Oracle Cloud Infrastructure Registry (OCIR). You need to ensure that these images never get deleted from the repository. Which action should you take?

A. Set global policy of image retention to " Retain All Images " .
B. Write a policy to limit access to the specific repository in your compartment.
C. Edit the tenancy global retention policy.
D. Create a group and assign a policy to perform lifecycle operations on images.

Answer: A

Explanation:
To prevent images from being deleted from a repository, you can set the global policy of image retention to
"Retain All Images". This policy applies to all repositories in the tenancy and overrides any individual repository settings. You can also lock the policy to prevent any changes to it.Verified References: Using Retention Rules to Preserve Data

NEW QUESTION # 52
How are cloud native application versions deployed to an OKE cluster when using a blue/green deployment strategy?

A. New application versions are deployed in minor increments to a select group of people.
B. Current applications are slowly replaced with new application versions.
C. Both old and new application versions are deployed to production at the same time.

Answer: C

Explanation:
Blue/Green deployment strategy allows releasing a new version of an application using two identical environments where one of them is active at a given time. The current version of the application is provisioned on the active environment, whereas the new version gets deployed to the standby environment1. The traffic is shifted from the active to the standby environment by updating the ingress resource2. Therefore, both old and new application versions are deployed to production at the same time, but only one of them receives the traffic.

NEW QUESTION # 53
You have built a local container image named order-processor:1.0 and need to push it to a repository named order-services in your Phoenix region (phx) tenancy, which has the Object Storage namespace ax39m19vpw.
Which command must you run to properly tag the local image before pushing it to Container Registry?

A. docker tag order-processor:1.0 ax39m19vpw/phx.ocir.io/order-services:1.0
B. docker tag order-processor:1.0 ax39m19vpw/order-services/phx.ocir.io:1.0
C. docker tag order-processor:1.0 phx.ocir.io/ax39m19vpw/order-services:1.0
D. docker tag order-processor:1.0 ocir.phx.oraclecloud.com/ax39m19vpw/order-services:1.0

Answer: C

Explanation:
OCI Container Registry requires the destination image tag to use the structure < region-key > .ocir.io/ < tenancy-namespace > / < repository-name > : < tag > . For Phoenix, the region key is phx; the supplied tenancy namespace is ax39m19vpw; the repository is order-services; and the image tag is 1.0. Combining these values produces phx.ocir.io/ax39m19vpw/order-services:1.0. Oracle ' s current container documentation provides the same docker tag structure before an image is pushed to OCIR. The alternative commands incorrectly reorder the namespace and registry host or use an unsupported registry hostname format.
Therefore, option A correctly retags the local order-processor:1.0 image with the fully qualified OCIR repository path required for the subsequent docker push.

NEW QUESTION # 54
Which of the following TWO statements are TRUE about deleting a Kubernetes cluster? (Choose two.)

A. Changing the auto-generated name of a worker node does not affect the deletion of the worker node when the cluster in which it is created is deleted.
B. You cannot change the autogenerated names of the worker nodes in the format oke-c < part-of cluster- CCID > - < part-of-node-pool-OCID > - < part-of-subnet-OCID > - < slot > within a Kubernetes cluster.
C. If you change the auto-generated name of a worker node and then delete the cluster, the renamed worker node is not deleted.
D. Upon deleting a cluster, no other resources created during the cluster creation process or associated with the cluster (such as VCNS. Internet Gateways, NAT Gateways, Route Tables, Security Lists. Load Balancers, and Block Volumes) are deleted automatically.
E. Upon deleting a cluster, other resources created during the cluster creation process or associated with the cluster (such as VCNS, Internet Gateways, NAT Gateways, Route Tables, Security Lists, B. Load Balancers, and Block Volumes) are deleted automatically.

Answer: C,D

Explanation:
The correct statements about deleting a Kubernetes cluster are: If you change the auto-generated name of a worker node and then delete the cluster, the renamed worker node is not deleted. Changing the name of a worker node does not affect its deletion when the cluster is deleted. The cluster deletion process does not consider the renamed worker nodes and will delete all worker nodes associated with the cluster. Upon deleting a cluster, no other resources created during the cluster creation process or associated with the cluster (such as VCNs, Internet Gateways, NAT Gateways, Route Tables, Security Lists, Load Balancers, and Block Volumes) are deleted automatically. These additional resources are not automatically deleted when the cluster is deleted. You need to manage the deletion of these resources separately, if desired. Therefore, the correct statements are that the renamed worker nodes are not deleted when the cluster is deleted, and other associated resources are not automatically deleted when the cluster is deleted.

NEW QUESTION # 55
Which TWO are required to access the Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster from the kubectl CLI? (Choose two.)

A. OCI Identity and Access Management (IAM) Auth Token.
B. A configured OCI API signing key pair.
C. An SSH key pair with the public key added to the cluster worker nodes.
D. Tiller enabled on the OKE cluster.
E. Install and configure the OCI CLI.

Answer: B,E

Explanation:
The correct options are: A configured OCI API signing key pair: The API signing key pair is used for authentication and authorization to access OCI resources, including the OKE cluster. The private key should be configured on your local machine to authenticate API requests. An SSH key pair with the public key added to the cluster worker nodes: This is required for secure SSH access to the worker nodes in the OKE cluster.
You need to generate an SSH key pair and add the public key to the cluster ' s worker node pool during cluster creation or update. Therefore, the correct options are having a configured OCI API signing key pair and an SSH key pair with the public key added to the cluster worker nodes.
