Shutting down the environment after work hours is the best process to automate to reduce cost, as it will stop incurring charges for the cloud resources that are not needed outside of work hours. Scaling, implementing access control, or blocking external access may still incur some costs for the cloud resources that are running or reserved, even if they are not fully utilized. Shutting down the environment can be automated using scripts, schedules, or triggers that can turn off or deallocate the cloud resources based on time or usage criteria12.

Telnet and FTP are recommended services to be disabled when deploying a server in a cloud platform, as they are insecure protocols that transmit data in plain text and expose credentials and sensitive information to potential attackers12. Remote log-in, DNS, DHCP, and LDAP are not necessarily recommended to be disabled, as they may provide useful functionality for the server and the cloud environment. However, they should be configured properly and secured with encryption, authentication, and authorization mechanisms34.

The correct answer is C. Legal hold.

A legal hold is a process that organizations use to preserve relevant electronic information when they anticipate litigation or have an active e-discovery request. A legal hold requires that certain email messages be retained and unaltered until they are no longer required for court use. Legal hold requirements apply both to the content of messages as well as the metadata which can provide proof of delivery and other critical non-repudiation information12.

Email archiving is a process that organizations use to store email messages for long-term retention, compliance, and backup purposes. Email archiving does not necessarily imply that the email messages are preserved for legal purposes, although some email archiving solutions may offer legal hold capabilities1.

Version control is a process that software developers use to manage changes to source code and other files in a project. Version control allows developers to track, compare, and revert changes, as well as collaborate with other developers. Version control does not apply to email messages or legal hold.

File integrity monitoring is a process that security professionals use to detect unauthorized or malicious changes to files and directories on a system. File integrity monitoring helps to protect the system from malware, data breaches, and configuration errors. File integrity monitoring does not apply to email messages or legal hold.

The correct answers are B and D.

B. Reduced monthly costs: One of the main advantages of public cloud is that it lowers the costs of IT infrastructure and maintenance for the customers. They do not need to purchase, install, or manage any hardware or software, and they only pay for the resources they use. This can result in significant savings compared to owning and operating a private cloud or an on-premise data center1234

D. Pay as you use: Another benefit of public cloud is that it offers a flexible and scalable pricing model based on the actual usage of the customers. They can adjust their resource consumption according to their changing needs and demands, and only pay for what they use. This eliminates the need for upfront capital investment or long-term contracts, and allows customers to optimize their spending and performance1234
