Disabling unneeded physical ports would prevent unauthorized devices from being connected to the server, such as an outside USB drive. Setting a BIOS password would restrict access to the boot settings and prevent unauthorized changes to the boot order. The other options would not address the risk of booting from an outside USB drive

If the network cable is functioning but there is no network connectivity, the next step would be to check the IPv4 options. This includes verifying that the server has a correct IP address, subnet mask, and gateway configuration.
* IPv4 options (Answer B): Incorrect IP configuration is a common reason for network connectivity issues.
* NIC firmware (Option A): Firmware issues are less likely if the NIC is detecting the cable and appears operational.
* DHCP options (Option C): DHCP could be checked if automatic IP assignment is being used, but verifying IPv4 options manually is the first step.
* Firewall options (Option D): Firewalls can block connectivity but should be checked after confirming IP settings.
* DNS settings (Option E): DNS issues usually affect domain name resolution, not basic network connectivity.

The Recovery Point Objective (RPO) refers to the maximum tolerable period in which data might be lost from an IT service due to a major incident. The policy mentioned in the question highlights that data loss exceeding one hour is unacceptable, directly relating to the RPO concept. RPO is critical in disaster recovery and business continuity planning, indicating the age of the files that must be recovered from backup storage for normal operations to resume without significant losses. MTTR (Mean Time To Repair), RTO (Recovery Time Objective), and MTBF (Mean Time Between Failures) are related concepts but do not specifically address the amount of data loss that can be tolerated.

This is the most secure method to access servers located in remote branch offices because MFA stands for multi-factor authentication, which requires users to provide more than one piece of evidence to prove their identity. An out-of-band solution means that one of the factors is delivered through a separate channel, such as a phone call, a text message, or an email. This adds an extra layer of security and prevents unauthorized access even if a password is compromised. References:

The WinSCP tool is commonly used to transfer files between Linux and Windows systems.
WinSCP has an easy GUI and encrypts the contents of the file transfer.
