Your company uses the Oracle Cloud Infrastructure (OCI) Object Storage service to share large data sets with its data science team. The data science team consists of 20 people who work from offices in Washington, D.C., and Tokyo. While working in these offices, employees are assigned an IP address from the public IP range 129.146.31.0/27

  • B. Set the bucket visibility to public and only share the URL with the data science team via email
  • C. Create a pre-authenticated request for each data set and only share with the data science team via email
  • D. Create a Network Source named CorpNetwork with a CIDR block of 129.146.31.0/27

Correct Answers are A,D. I just think that answer "A" is missing the rest of the word, it should be "CorpNetwork". The rest of the answers just don't make sense. Admins pretty please review the answers for this one. Thanks.

Selected Answer: AD
Introduction to Network Sources A network source is a set of defined IP addresses. The IP addresses can be public IP addresses or IP addresses from VCNs within your tenancy. After you create the network source, you can reference it in policy or in your tenancy's authentication settings to control access based on the originating IP address. https://docs.oracle.com/en-us/iaas/Content/Identity/Tasks/managingnetworksources.htm this means that AD are correct. 1.D. make a network name 2.A. Make a policy.

What would be the point in creating a network source name and then not creating a rule to use it? What is the relevance of creating a PAR, since the requirement is to limit the accessibility of the files to a certain specific location (identified via the endpoint's ip addresses?

agree: To restrict access to requests made from a set of IP addresses, do the following: 1. Create a network source that specifies the allowed IP addresses. 2. Write a policy that uses the network source variable in a condition

Also the question starts with "Which two steps ..." . That confirms D and A as the correct answer because A follows D as a 2-step solution
