NEW QUESTION 35
Move each protocol from the list on the left to its correct example on the right.

Explanation:
The correct matching of the protocols to their examples is as follows:
* DHCP: Assign the reserved IP address 10.10.10.200 to a web server at your company.
* DNS: Perform a query to translate companypro.net to an IP address.
* ICMP: Perform a ping to ensure that a server is responding to network connections.
Here’s how each protocol corresponds to its example:
* DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses to devices on a network. In this case, DHCP would be used to assign the reserved IP address 10.10.10.200 to a web server.
* DNS (Domain Name System) is used to translate domain names into IP addresses. Therefore, to translate companypro.net to an IP address, DNS would be utilized.
* ICMP (Internet Control Message Protocol) is used for sending error messages and operational information indicating success or failure when communicating with another IP address. An example of this is using the ping command to check if a server is responding to network connections.
These protocols are essential for the smooth operation of networks and the internet.
* Perform a query to translate companypro.net to an IP address.
* DNS (Domain Name System): DNS is used to resolve domain names to IP addresses.
* Assign the reserved IP address 10.10.10.200 to a web server at your company.
* DHCP (Dynamic Host Configuration Protocol): DHCP is used to assign IP addresses to devices on a network.
* Perform a ping to ensure that a server is responding to network connections.
* ICMP (Internet Control Message Protocol): ICMP is used by network devices to send error messages and operational information, and it is the protocol used by the ping command.
* DNS (Domain Name System): DNS translates human-friendly domain names like “companypro.net” into IP addresses that computers use to identify each other on the network.
* DHCP (Dynamic Host Configuration Protocol): DHCP automatically assigns IP addresses to devices on a network, ensuring that no two devices have the same IP address.
* ICMP (Internet Control Message Protocol): ICMP is used for diagnostic or control purposes, and the ping command uses ICMP to test the reachability of a host on an IP network.

NEW QUESTION 36
A user reports that a company website is not available. The help desk technician issues a tracert command to determine if the server hosting the website is reachable over the network.
The output of the command is shown as follows:

What can you tell from the command output?

The router at hop 3 is not forwarding packets to the IP address 192.168.1.10.

The server address 192.168.1.10 is being blocked by a firewall on the router at hop 3.

The server with the address 192.168.1.10 is reachable over the network.

Requests to the web server at 192.168.1.10 are being delayed and time out.
