You are configuring a new file server for your company's local network. The network includes a variety of devices, including some legacy systems that still require SMB1 for file sharing.
However, you are aware of the security vulnerabilities associated with SMB1. You want to ensure that the network is secure while still accommodating the legacy systems.
What is the BEST approach for you to take in this situation?
Enable SMB1 on the file server and disable all other versions of SMB.
Enable SMB1 but also enable SMB3 and configure message encryption for sensitive shares.
Completely disable SMB on the file server and use FTP for file sharing instead.
Disable SMB1 and require all devices to use SMB3.
Enable SMB1 but also enable SMB3 and configure message encryption for sensitive shares.
What should be done with data that has been lost between the Recovery Point Objective (RPO) and the present time?
It should trigger an immediate system shutdown.

It should be accepted as a loss or reconstructed.
It should be ignored as it is not critical.
It should be accepted as a loss or reconstructed.

During a routine audit, it's discovered that the Recovery Time Objective (RTO) for a critical system is set to 24 hours. However, the business impact analysis (BIA) indicates that any downtime longer than 12 hours could result in significant financial and reputational damage.
What should be the immediate course of action?
Adjust the RTO to align with the findings of the BIA.
Conduct a tabletop exercise focusing on other non-critical systems.
Increase the RTO to 48 hours to provide more flexibility.
Ignore the BIA findings as the current RTO has been effective so far.
Adjust the RTO to align with the findings of the BIA.
You are setting up a new office for your company, which includes installing VoIP phones for all employees.
You want to ensure that voice traffic does not interfere with the company's data traffic and vice versa. You also want to make sure that the VoIP phones can be used even if there are power outages.
What should you do to meet these requirements?
Configure separate VLAN IDs for voice and data traffic and use traditional power cables for the VoIP phones.
Configure separate VLAN IDs for voice and data traffic and ensure the VoIP phones support Power over Ethernet (PoE).
Use digital certificates and connect phones directly to the Internet without a LAN.
Connect all VoIP phones to a dedicated Wi-Fi network separate from the company's main network
Configure separate VLAN IDs for voice and data traffic and ensure the VoIP phones support Power over Ethernet (PoE).
