A security engineer wants to provide a secure, dedicated, alternate access method into an IT network infrastructure to administer connected devices and IT assets. Which of the following is the engineer most likely to implement?
Correct Answer:
C
Out-of-band management is a method of accessing network devices and IT assets through a dedicated channel that is separate from the normal data traffic. This provides a secure and alternate way to administer the network infrastructure, especially in case of failures or emergencies. Remote desktop gateway is a service that allows remote access to desktops and applications on a network. Authentication and authorization controls are mechanisms that verify the identity and permissions of users and devices on a network. Secure Shell is a protocol that encrypts the communication between a client and a server on a network.

A technician discovered that some information on the local database server was changed during a tile transfer to a remote server. Which of the following should concern the technician the MOST?
Correct Answer:
B
The technician should be most concerned about data integrity and security. If information on the local database server was changed during a file transfer to a remote server, it could indicate that unauthorized access or modifications were made to the data. It could also indicate a failure in the file transfer process, which could result in data loss or corruption. The technician should investigate the cause of the changes and take steps to prevent it from happening again in the future. Additionally, they should verify the integrity of the data and restore it from a backup if necessary to ensure that the correct and complete data is available. The technician should also take appropriate actions such as notifying the system administrator and management of the incident, and following the incident management process to minimize the damage caused by the incident.
