 In Transport mode encryption of an IPsec server, only the payload of the data packet is encrypted. This mode is designed to encrypt the message within an IP packet, while the header remains unencrypted. Transport mode is used for end-to-end communication between a client and a server, where the server can interpret the headers to route the packet to the correct application or process.

References: The information is consistent with the IPsec standards and documentation, which specify that in Transport mode, the data within the original IP packet is protected, but not the IP header123. This ensures that the packet retains its original IP header, allowing it to be routed properly through the network.

The correct answer is Recovery Time Objective (RTO). RTO is a critical metric in disaster recovery (DR) and business continuity (BC) planning. It defines the target time within which a business process must be restored after a disaster to avoid unacceptable consequences associated with a break in business continuity. It is essentially the maximum acceptable length of time that a computer, system, network, or application can be down after a failure or disaster occurs. An RTO is set by business continuity planners to ensure that the DR and BC solutions are designed to meet the specific time constraints of the organization.

References: The explanation provided is based on standard definitions and practices within the field of disaster recovery and business continuity planning. The RTO is a well-established concept in DR and BC solutions, as outlined in various authoritative resources on the subject1234. For the most accurate and detailed reference, it is recommended to consult the official documents and study guides from the Certified Network Defender (CND) course by the EC-Council.

In Linux, to disable a user account, the usermod command is used with the -L option. This option locks the user’s password, effectively disabling the account by preventing the user from logging in. The command usermod -L alice will lock the user ‘alice’ by adding an exclamation mark (!) in front of the encrypted password in the /etc/shadow file, which is the standard method for disabling an account in Linux.

References: This information is consistent with standard Linux administration practices and is also in line with the objectives of the EC-Council’s Certified Network Defender (CND) program, which includes understanding and managing user accounts and permissions as part of network security1.
