A PC can not connect to any remote websites, ping its default gateway, or ping a printer that is functioning properly on the local network segment. Which action will verify that the TCP/IP stack is functioning correctly on this PC?
- A.
Use the ipconfig /all command at the host�s command prompt.
- B.
Use the ping 127.0.0.1 command at the command prompt.
- C.
Use the traceroute command at the command prompt to identify any failures on the path to the gateway.
- D.
Use FTP to check for connectivity to remote sites.
- E.
Download a troubleshooting tool from the PC manufacturer's website
Correct Answer
B. Use the ping 127.0.0.1 command at the command prompt.Explanation
Using the ping 127.0.0.1 command at the command prompt will verify that the TCP/IP stack is functioning correctly on the PC. The IP address 127.0.0.1 is the loopback address, which means it refers to the local host or the PC itself. By pinging this address, the PC is essentially testing its own network connectivity and the functionality of the TCP/IP stack. If the ping is successful, it indicates that the PC's network stack is working properly.Rate this question:

In a Cisco IOS device, where is the startup-configuration file stored?
- A.
Flash
- B.
NVRAM
- C.
RAM
- D.
ROM
Correct Answer
B. NVRAMExplanation
The startup-configuration file in a Cisco IOS device is stored in NVRAM (non-volatile random access memory). NVRAM is a type of memory that retains its data even when the device is powered off or restarted. This ensures that the configuration file is preserved and can be loaded during the startup process. Flash memory is another storage option in Cisco devices, but it is typically used for storing the operating system and other files, not the startup configuration. RAM (random access memory) is volatile memory that is used for temporary storage while the device is powered on. ROM (read-only memory) contains the firmware and basic operating system of the device.Rate this question:

A routing issue has occurred in you internetwork. Which of the following type of devices should be examined to isolate this error?
- A.
Access point
- B.
Host
- C.
Hub
- D.
Router
- E.
Switch
Correct Answer
D. RouterExplanation
If a routing issue has occurred in the internetwork, the device that should be examined to isolate the error is the router. Routers are responsible for directing network traffic between different networks, so if there is a problem with routing, it is likely that the router is causing the issue. The other devices listed (access point, host, hub, and switch) do not perform routing functions, so they are less likely to be the source of the problem.Rate this question:

Which OSI layer protocol does IP rely on to determine whether packets have been lost and to request retransmission?
- A.
Application
- B.
Presentation
- C.
Session
- D.
Transport
Correct Answer
D. TransportExplanation
IP relies on the transport layer protocol to determine whether packets have been lost and to request retransmission. The transport layer protocols, such as TCP (Transmission Control Protocol), provide reliable delivery of data by implementing mechanisms like acknowledgments and retransmissions. These mechanisms allow IP to detect and recover from packet loss, ensuring that the data is successfully transmitted from the source to the destination.Rate this question:

What are the three characteristics of CSMA/CD? Devices can be configured with a higher transmission priority. A jam signal indicates that the collision has cleared and the media is not busy.
- A.
A device listens and waits until the media is not busy before transmitting.
- B.
The device with the electronic token is the only one that can transmit after a collision.
- C.
All of the devices on a segment see data that passes on the network medium.
- D.
After detecting a collision, hosts can attempt to resume transmission after a random time delay has expired.
Correct Answer(s)
A. A device listens and waits until the media is not busy before transmitting.
C. All of the devices on a segment see data that passes on the network medium.
D. After detecting a collision, hosts can attempt to resume transmission after a random time delay has expired.Explanation
The correct answer is "A device listens and waits until the media is not busy before transmitting." This is one of the characteristics of CSMA/CD, where a device must check if the network medium is busy before transmitting to avoid collisions. Another correct characteristic is "All of the devices on a segment see data that passes on the network medium." This means that all devices connected to the same segment can see the data being transmitted on the network. Additionally, "After detecting a collision, hosts can attempt to resume transmission after a random time delay has expired" is also a characteristic of CSMA/CD, where hosts wait for a random time period before attempting to transmit again after a collision.Rate this question:

When must a router serial interface be configured with the clock rate command?
- A.
When the interface is functioning as a DTE device
- B.
When the interface timers have been cleared
- C.
When the connected DTE device is shut down
- D.
when the interface is functioning as a DCE device
Correct Answer
D. when the interface is functioning as a DCE deviceExplanation
The router serial interface must be configured with the clock rate command when it is functioning as a DCE device. This command is used to set the clock rate on the router's serial interface, which is necessary for proper communication between DCE and DTE devices. The clock rate is typically set on the DCE device, such as a CSU/DSU, and not on the DTE device. Therefore, when the router interface is functioning as a DCE device, it needs to be configured with the clock rate command.Rate this question:
