With PKI offering that extra security between communications, we can maintain authentication, confidentiality, and Access Control. Once you have your website set, a Digital Certificate authority will first verify that you own a website and then sign their certificate so it it trusted by internet browsers
The destination ip address when an ipv4 host sends a DHCPDISCOVER message Because a DHCP client does not have a valid IPv4 address, it must use a broadcast IP address of 255.255. 255.255 as the destination address to communicate with the DHCP server.
<h3>What does the DHCP server do when it receives the Dhcpdiscover message?</h3>
When the lease has expired, the client must start over with the DHCPDISCOVER process. The client ends the lease by sending a DHCPRELEASE message to the DHCP server. The server will then return the client's IP address to the available address pool.
<h3>What is a Dhcpdiscover message?</h3>
The DHCPDISCOVER message contains an identifier unique to the client (typically the MAC address). The message might also contain other requests, such as requested options (for example, subnet mask, domain name server, domain name, or static route). The message is sent out as a broadcast.

Answer:
The answer is "Plug and play".
Explanation:
A switch with minimum debugging tools for log-and-play simplicity and also no IP address. The Unmanaged switches are cost-effective and also have limited power, and other choices are not correct, which can be described as follows:
- Fast Ethernet provides 10 to 100 Mbps speeds, that's why it is not correct.
- Gigabit provides bandwidth, which is up to 1 Gbps speed, and it is 10 times faster than Ethernet Fast, that's why it is wrong.
- The trunk provides the link design that's why it is not correct.
