• Question 217:

  A cloud administrator has configured a connection between two virtual private cloud environments at a public cloud provider that are each in different accounts. The administrator has configured the accounts correctly so they can connect to each other's resources. Both cloud environments have policies that allow anyone from 0.0.0.0/0 on TCP port 22. The following table shows the network configuration information:

  

  However, the administrator is unable to establish an SSH connection from a server in 10.250.40.100 to 10.250.48.214. Which of the following is the MOST likely issue?

  A. The network ACL is not configured to allow SSH access.

  B. The IP configuration on one of the servers is incorrect.

  C. The administrator does not have sufficient credentials.

  D. The routing tables have not been updated correctly.

  Correct Answer: D

• Question 218:

  A systems administrator for an e-commerce company will be migrating the company's main website to a cloud provider. The principal requirement is that the website must be highly available.

  Which of the following will BEST address this requirement?

  A. Vertical scaling

  B. A server cluster

  C. Redundant switches

  D. A next-generation firewall

  Correct Answer: B

  A server cluster is a group of servers that work together to provide high availability, load balancing, and scalability for applications or services. A server cluster can help ensure the high availability requirement for migrating an e-commerce company's main website to a cloud provider, as it can prevent downtime or disruption in case of a server failure or outage by automatically switching the workload to another server in the cluster. A server cluster can also improve performance and reliability, as it can distribute the workload across multiple servers and handle increased traffic or demand.

• Question 219:

  A cloud architect wants to minimize the risk of having systems administrators in an IaaS compute instance perform application code changes. The development group should be the only group allowed to modify files in the directory.

  Which of the following will accomplish the desired objective?

  A. Remove the file write permissions for the application service account.

  B. Restrict the file write permissions to the development group only.

  C. Add access to the fileshare for the systems administrator's group.

  D. Deny access to all development user accounts

  Correct Answer: B

  File write permissions are permissions that control who can modify or delete files in a directory or system. Restricting the file write permissions to the development group only can help minimize the risk of having systems administrators in an IaaS compute instance perform application code changes, as it can prevent anyone other than the development group from altering or removing any files in the directory where the application code is stored. Restricting the file write permissions can also help maintain consistency and integrity, as it can ensure that only authorized and qualified users can make changes to the application code.

• Question 220:

  A Chief Information Security Officer (CISO) is evaluating the company's security management program. The CISO needs to locate all the assets with identified deviations and mitigation measures. Which of the following would help the CISO with these requirements?

  A. An SLA document

  B. ADR plan

  C. SOC procedures

  D. A risk register

  Correct Answer: D

  A risk register is a document that records all the identified risks, their causes, impacts, probabilities, mitigation measures, and status for a project or an organization. A risk register helps to manage and monitor risks throughout their lifecycle and ensure they are addressed appropriately. A risk register would help the CISO to locate all the assets with identified deviations and mitigation measures.
