Cisco 100-150 Dumps Questions Answers

To determine if you can reach the router, you should use the ping command followed by the IP address of the router. The ping command is a network utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer.

The Default Gateway in the ipconfig results is typically the router’s IP address in a home or small office network. In this case, the Default Gateway is 192.168.0.1, which is the address you would ping to check connectivity to the router.

How to Use the Ping Command

Testing Network Connectivity with the Ping Command

=========================

To determine if you can reach the router, you should use the ping command with the IP address of the router.

Command: ping

Target: 192.168.0.1

So, the completed command is:

ping 192.168.0.1

Step by Step Comprehensive and Detailed Explanation:

ping: The ping command sends ICMP Echo Request messages to the target IP address and waits for an Echo Reply. It is commonly used to test the reachability of a network device.

192.168.0.1: This is the IP address of the default gateway (the router) as shown in the ipconfig output. Pinging this address will help determine if the computer can communicate with the router.

The tracert command is used to determine the route taken by packets across an IP network. When a user reports that an external web page is not loading, while other resources are accessible, it suggests there might be an issue at a certain point in the network path to the specific web page. The tracert command helps to diagnose where the breakdown occurs by displaying a list of routers that the packets pass through on their way to the destination. It can identify the network segment where the packets stop progressing, which is valuable for pinpointing where the connectivity issue lies.

•tracert Command: This command is used to determine the path packets take to reach a destination. It lists all the hops (routers) along the way and can help identify where the delay or failure occurs.

•ping -t: This command sends continuous ping requests and is useful for determining if a host is reachable but does not provide path information.

•ipconfig /all: This command displays all current TCP/IP network configuration values and can be used to verify network settings but not to trace a network path.

•nslookup: This command queries the DNS to obtain domain name or IP address mapping, useful for DNS issues but not for tracing network paths.

The correct matching of the MFA factors to their examples is as follows:

Entering a one-time security code sent to your device after logging in: Possession

Holding your phone to your face to be recognized: Inherence

Specifying your user name and password to log on to a service: Knowledge

Here’s why each factor matches the example:

Possession: This factor is something the user has, like a mobile device. A one-time security code sent to this device falls under this category.

Inherence: This factor is something the user is, such as a biometric characteristic. Facial recognition using a phone is an example of this factor.

Knowledge: This factor is something the user knows, like a password or PIN.

Multi-Factor Authentication (MFA) enhances security by requiring two or more of these factors to verify a user’s identity before granting access.

Entering a one-time security code sent to your device after logging in.

Factor: Possession

Explanation: This factor relates to something you have, such as a device that receives a security code.

Holding your phone to your face to be recognized.

Factor: Inference (typically referred to as Inherence or Biometric)

Explanation: This factor relates to something you are, such as biometric authentication like facial recognition.

Specifying your username and password to log on to a service.

Factor: Knowledge

Explanation: This factor relates to something you know, such as a username and password.

Possession Factor: This involves something the user has in their possession. Receiving a one-time security code on a device (e.g., phone) is an example of this.

Inference Factor (Inherence/Biometric): This involves something inherent to the user, such as biometric verification (e.g., facial recognition or fingerprint scanning).

Knowledge Factor: This involves something the user knows, such as login credentials (username and password).
