Linux Foundation CKS Exam - Topic 1 Question 54 Discussion

Secrets stored in the etcd is not secure at rest, you can use the etcdctl command utility to find the secret valuefor e.g:-ETCDCTL_API=3 etcdctl get /registry/secrets/default/cks-secret --cacert="ca.crt" --cert="server.crt" --key="server.key"OutputUsing the Encryption Configuration, Create the manifest, which secures the resource secrets using the provider AES-CBC and identity, to encrypt the secret-data at rest and ensure all secrets are encrypted with the new configuration.
A) Explanation: ETCD secret encryption can be verified with the help ofetcdctlcommand line utility. ETCD secrets are stored at the path/registry/secrets/$namespace/$secreton the master node. The below command can be used to verify if the particular ETCD secret is encrypted or not. # ETCDCTL_API=3 etcdctl get /registry/secrets/default/secret1 [...] | hexdump -C

This seems like a good opportunity to demonstrate my understanding of etcd security and encryption. I'll start by running the etcdctl command to confirm the secret is stored in plaintext. Then I'll carefully craft the encryption configuration manifest to ensure all secrets are properly encrypted at rest.

Okay, I think I've got this. First, I'll use etcdctl to verify the secret value is not encrypted. Then I'll create a manifest with the encryption configuration to secure the secrets using AES-CBC. Shouldn't be too difficult as long as I get the details right in the manifest.

This question seems straightforward. I'll start by using the etcdctl command to check the secret value, as shown in the example. Then I'll need to create a manifest to configure encryption for the secrets using the AES-CBC provider and identity.

Hmm, I'm a bit confused about the encryption configuration part. I'll need to review the details on how to set that up properly in the manifest. The etcdctl command looks simple enough, but I want to make sure I understand the encryption requirements fully.

This is a tricky one. The details about the insurer acting as an agent and making the actual claim payments from Flair's account don't seem to match up perfectly with any of the answer choices. I'm going to have to think this through step-by-step to figure out the right approach.

Okay, let's see. The question mentions customer service, so I'm guessing the Case entity would be a good choice. And maybe something like Goal or Social activity could also be used. I'll select those and see how it goes.
