NEW QUESTION # 34
Which Cisco CPAK 100GBASE module supports Multimode Fiber cable?

  • A. Cisco CPAK-100G-ER4L
  • B. Cisco CPAK-100G-SR4
  • C. Cisco CPAK-100G-CWDM4
  • D. Cisco CPAK-100G-LR4

Answer: B

Explanation:
The Cisco CPAK-100G-SR4 module is designed to support Multimode Fiber (MMF) cable. It is specifically engineered for high-bandwidth 100G optical links and supports link lengths of up to 70 meters over OM3 and 100 meters over OM4 Multimode Fiber with MPO connectors. This module is well-suited for short-range, high-speed data communications and data center applications where Multimode Fiber is typically used due to its ability to handle the large amount of data traffic over relatively short distances.

NEW QUESTION # 35
Which address facilitates the routing of packets over an IP network?

  • A. MAC
  • B. network
  • C. physical
  • D. transport

Answer: B

Explanation:
The address that facilitates the routing of packets over an IP network is the network address. In the context of IP networking, this refers to the IP address, which is used to identify each host on a network and to determine the best path for data packets to travel from their source to their destination. Routers use IP addresses to make decisions about where to forward packets so that they reach the correct destination. The network layer of the OSI model, where IP operates, is responsible for this routing process123.
The other options listed do not facilitate routing in the same way:
Physical (A) and MAC (D) addresses are used at the data link layer to deliver packets on the same local network.
Transport (B) refers to the transport layer, which is responsible for end-to-end communication and data flow control but does not route packets over an IP network.


NEW QUESTION # 36
Which command shows the status of power supplies and sensor temperatures?

  • A. show module
  • B. show environment
  • C. show diag
  • D. show hardware

Answer: B

Explanation:
The show environment command in Cisco devices is used to display the status of the system's environment, including power supplies and sensor temperatures. This command provides a comprehensive overview of the environmental conditions affecting the device, such as temperature readings and power supply status.
Option A, show hardware, is not specific to power supplies and sensor temperatures. Option B, show module, displays information about the network modules installed in the device but not the environmental conditions. Option D, show diag, is used for diagnostic purposes and does not specifically provide the status of power supplies and sensor temperatures.
Therefore, the correct answer is C, show environment, which is the command that specifically shows the status of power supplies and sensor temperatures in Cisco devices12.
Reference:
Cisco Community discussions on power supply details1.
Cisco documentation on Environmental Monitoring and Power Management2.


NEW QUESTION # 37
What is the Windows-based program that executes the ping command to test network connectivity?

  • A. Find
  • B. cmd
  • C. ipconfig
  • D. Start

Answer: B

Explanation:
The cmd program, also known as the Command Prompt, is the primary command-line interface in Windows. It allows you to execute various commands, including the ping command, to perform network testing and troubleshooting.
Here's how to use ping in the Command Prompt:
Open the Command Prompt: Search for 'cmd' in the Windows Start Menu or use the Run dialog (Windows key + R) and type 'cmd'.
Type the ping command: Enter ping followed by a space and then either the IP address or hostname you want to test. For instance: ping 8.8.8.8 or ping www.google.com.
Press Enter: The Command Prompt will send ping requests and display the results.
Why other options are incorrect:
Find: The Find utility in Windows is used to search for files and folders based on their content or attributes.
Start: The Start Menu in Windows provides access to programs, settings, and power options.
ipconfig: The ipconfig command is used to display network configuration information but doesn't directly execute the ping command.
