A Cisco PoE switch is shown in the following image.
Which type of port will provide both data connectivity and power to an IP phone?
- A . Port identified with number 2
- B . Ports identified with numbers 3 and 4
- C . Ports identified with number 6
- D . Ports identified with number 7
C
Explanation:
In the provided image of the Cisco PoE switch, the ports identified with number 6 are the standard RJ-45 Ethernet ports typically found on switches that provide both data connectivity and Power over Ethernet (PoE). PoE ports are designed to supply power to devices such as IP phones, wireless access points, and other PoE-enabled devices directly through the Ethernet cable.
Ports:
• 2: Console port (for management and configuration)
• 3 and 4: Specific function ports (often for management)
• 6: RJ-45 Ethernet ports (capable of providing PoE)
• 7: SFP ports (for fiber connections, typically do not provide PoE) Thus, the correct answer is C. Ports identified with number 6.

Which address is included in the 192.168.200.0/24 network?
- A . 192.168.199.13
- B . 192.168.200.13
- C . 192.168.201.13
- D . 192.168.1.13
B
Explanation:
• 192.168.200.0/24 Network: This subnet includes all addresses from 192.168.200.0 to 192.168.200.255.
The /24 indicates a subnet mask of 255.255.255.0, which allows for 256 addresses.
• 192.168.199.13: This address is in the 192.168.199.0/24 subnet, not the 192.168.200.0/24 subnet.
• 192.168.200.13: This address is within the 192.168.200.0/24 subnet.
• 192.168.201.13: This address is in the 192.168.201.0/24 subnet, not the 192.168.200.0/24 subnet.
• 192.168.1.13: This address is in the 192.168.1.0/24 subnet, not the 192.168.200.0/24 subnet.

DRAG DROP
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.
