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?
Correct Answer:
C
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. References :=

A local company requires two networks in two new buildings. The addresses used in these networksmust be in the private network range.
Which two address ranges should the company use? (Choose 2.) Note: You will receive partial credit for each correct selection.
Correct Answer:
AD
The private IP address ranges that are set aside specifically for use within private networks and not routable on the internet are as follows:
✑ Class A: 10.0.0.0 to 10.255.255.255
✑ Class B: 172.16.0.0 to 172.31.255.255
✑ Class C: 192.168.0.0 to 192.168.255.255
These ranges are defined by the Internet Assigned Numbers Authority (IANA) and are used
for local communications within a private network123.
Given the options: A.172.16.0.0 to 172.31.255.255falls within the Class B private range. B. 192.16.0.0 to 192.16.255.255is not a recognized private IP range. C.11.0.0.0 to 11.255.255.255is not a recognized private IP range. D.192.168.0.0 to 192.168.255.255 falls within the Class C private range.
Therefore, the correct selections that the company should use for their private networks are
