1. Question 41 · 60 in bank

   You are developing a serverless application with Oracle Functions. Your function needs to store state in a database. Your corporate security standards mandate encryption of secret information like database passwords. As a function developer, which approach should you follow to satisfy this security requirement? (Choose the best answer.)

   • AUse the Oracle Infrastructure Console and enter the password in the function configuration section in the provided input field.
   • BUse Oracle Cloud Infrastructure Key Management to auto-encrypt the password. It will inject the auto-decrypted password inside your function container.
   • CEncrypt the password using Oracle Cloud Infrastructure Key Management. Decrypt this password in your function code with the generated key.
   • DAll function configuration variables are automatically encrypted by Oracle Functions.

   Show answer

   Answer: C

   Explanation

   The provided answer C, is correct. Create a KMS vault Create a Master Encryption Key Generate a Data Encryption Key (DEK) from the Master Encryption Key Use the DEK "plaintext" return value to encrypt the "sensitive value" (offline) Store the encrypted "sensitive value" as a config variable in the serverless application Store the DEK ciphertext and the initVector used to encrypt the "sensitive value" as Function config variables Within the function, decrypt the DEK ciphertext back into "plaintext" using the OCID and Cryptographic Endpoint by invoking the OCI KMS SDK Decrypt the "sensitive value" using the decrypted DEK "plaintext" and the initVector https://blogs.oracle.com/developers/oracle-functions-using-key-management-to-encrypt-and-decrypt-configuration-variables https://www.ateam-oracle.com/secure-storage-of-confidential-configuration-data-in-oracle-functions-using-oracle-oci-key-management-services

   Select 2

   Which two statements are true for serverless computing and serverless architectures? (Choose two.)

   • ALong running tasks are perfectly suited for serverless
   • BServerless function state should never be stored externally
   • CApplication DevOps team is responsible for scaling
   • DServerless function execution is fully managed by a third party
   • EApplications running on a FaaS (Functions as a Service) platform

   Show answer

   Answer: BE

   Explanation

   from fowler's serverless definition: it’s more accurate to say that any state of a FaaS function that is required to be persistent needs to be externalized outside of the FaaS function instance. So B is correct.
