Which of the following might be part of that action plan? Documenting the solution. Asking questions to fi nd out what has changed. Taking the storage device o ffl ine for a period of time. Ensuring user satisfaction. Explanation Your action plan might require purchases that need approval before proceeding or involve taking services o ffl ine (such as the storage device) for a period of time. Documenting the solution is the fi nal step in the troubleshooting process and comes after creating an action plan. Asking questions to fi nd out what has changed should have already been done before the action plan was created. Ensuring user satisfaction (like documenting the solution) comes after the action plan and fi xing the problem.

You are completing step 1 in the troubleshooting process and have already asked the employee to describe the issue and checked for error messages. What else should you do to identify the symptoms and potentials causes of the problem? (Select two.) Ask questions about any changes. Review the list of potential causes. Recreate the problem. Identify the a ff ected area. Look for common errors or solutions that can be tried quickly. Explanation When identifying a problem and its potential causes (step 1), you should ask the user to describe the problem and check for error messages (as you've already done in this scenario). In addition, you should: Recreate the problem. Identify the a ff ected area. Determine how large the problem is. Step 2 is based on asking question about any changes. Step 3 involves reviewing the list of potential causes and looking for common errors or solutions that can be tried quickly.

(Select three.) nslookup ss host netstat ifcon fi g tracepath dig Explanation

11/8/23, 5 : 56 AM Page 6 of 13 https://labsimapp.testout.com/v6_0_575/exam-engine.html/185b47e5-…n/31059775/783da08f-b2ef-464f-8624-23fec01f7276/end ? locale=en-us The dig , nslookup , and host commands are all designed to allow you to query a DNS server to resolve IP addresses and the FQDN or hostname. The dig command is the most powerful because you can retrieve the most information with it. The nslookup command is outdated and has been deprecated (or marked for retirement) and may disappear from Linux distributions some time in the future. The netstat command is used to display connection and other network information for the local system, not for retrieving information from a DNS server. The ifcon fi g command lets you assign an address to a network interface and con fi gure or display the current network interface con fi guration. The tracepath command lets you trace the path to a network destination. The ss command provides a secure encrypted connection between two hosts over an unsecure network.

The netstat command displays a list of network connections (e.g., sockets), the routing table, and information about the network interface. The dig command sends a name resolution request and receives extensive information about the hostname or IP address. The iperf command performs network throughput measurements.

You want to test connectivity on port 53 from other servers on the network. Which of the following commands will accomplish that task? ifcon fi g DHCP_03 traceroute DHCP_03 ping -c 53 DHCP_03 nc -zv DHCP_03 53 Explanation Use the nc -zv DHCP_03 53 command to accomplish the task. The netcat or nc command can scan a port and report if a connection was successfully established. The -z option tell the nc command to not actually send any data, but to report the connection status only. The v options indicates verbose mode. traceroute DHCP_03 will report the network route to that server. ifcon fi g DHCP_03 would look for a network device named DHCP_03. ping -c 53 DHCP_03 will ping the server 53 times.

You are able to connect to another system on the local network, but you are not able to connect to a server on a remote network. You suspect that the default gateway information for the system may be con fi gured incorrectly. Which of the following commands would you use to view the default gateway information on the Linux server? ifcon fi g dig netstat -r winipcfg Explanation You can use the netstat command with the -r option on systems running Linux to view the routing table, which includes the IP address of the default gateway. Use winipcfg to view network con fi guration information on Windows systems. Use the ifcon fi g command to con fi gure network interfaces or to display the status of currently active interfaces. Use the dig command on Linux and Unix systems to query Domain Name Service (DNS) servers.

You would like to view the information in an easily-readable format. Which of the following commands would meet your requirement? nmcli -f nmcli -m nmcli -p nmcli -t Explanation You would use the nmcli -p command to display a pretty output that is easily readable. The following are descriptions of the other listed options: -t displays terse output. The output is suitable for scripts. -m speci fi es mode, tabular or multiline. -f speci fi es column names.

After a few minutes, your web browser times out nd tells you that the website is unavailable. Which of the following troubleshooting steps would help you determine the cause of this issue? (Select two.) Use the ip addr command to test whether the IP address of the website you are trying to reach is correct. Use the traceroute command to traceroute the FQDN and IP address of the website you are trying to reach. Use the dig command to check information from the DNS server. Use the ping command to ping the FQDN and IP address of the website you are trying to reach. Use the route command to test the route to the FQDN and IP address of the website you are trying to reach. Explanation ping and traceroute are commands that can help you troubleshoot a network connectivity problem. route is used to view, add, and delete routes from your local machine's routing table and would not be helpful in this situation. ip addr is useful for determining your own network con fi guration information, but cannot be used to determine the network information for a remote computer. While dig may provide information about the DNS server. That information will probably not help in troubleshooting this issue. References 

You do get a response when you ping a host on your own network. Which of the following options would help you better determine where the problem is? Run nslookup on the internet computer's IP address. Run ip route trace on the IP address of the computer on the internet. Run traceroute on the IP address of the computer on the internet. ping the computer's FQDN (Fully Quali fi ed Domain name). Run netstat on the internet computer's IP address. Explanation

Unlike ping , it requests a reply from every router that it passes through to get to the speci fi ed host. This will help you determine where the problem is located in the path from your computer to the destination computer Attempting to ping the FQDN of a host when you cannot get a response from pinging its IP address will tell you nothing more; it actually tells you less because it introduces the possibility of problems with name resolution (DNS), which did not a ff ect prior results. nslookup also will not help you determine where the problem is because it will only query a DNS server. netstat is useful only for getting information about connections into and out of your computer. netstat does not help you determine where the problem is. ip route shows the routing table, but does not have a trace option.
