our client has hired you to change the command-line tool from nslookup to dig since it provides more detailed domain information than nslookup. Which of the following commands will you use to perform a DNS lookup on a domain name? 1.dig google.com 2.dig google.com ANY 3.apt-get i

Ann is a CSULA student trying to access (https://www.calstatela.edu) from the campus library. Her request must use Domain Name System (DNS) resolution to translate the name (https://www.calstatela.edu) to an IP address. Assume that CSULA DNS name resolution uses iterated queries and her request first goes to the CSULA local DNS server shown in the figure. In the following picture: 1. Fill in the blanks to show all the servers in the DNS hierarchy this request must be sent to, starting from and including the root DNS server. 2. Draw arrows with sequence numbers showing the steps in the DNS resolution. The first and the last step in DNS resolution are shown in the figure.

d. What is the IP address of the host on which the browser is running?    e. What type of browser initiates this message? Why is the browser type needed in  an HTTP request message?

Back Story What is our domain name? Security.local   Can you ping our domain name?   Yes   If you cannot ping the domain name (which you should be able to, you most likely have a DNS issue).

If not – type this:   Ipconfig /flushdns – this will release current DNS info   Ipconfig /registerdns – this will reregister DNS info   *Do you see DNS servers? If not – type this:   Ipconfig /renew – this will ‘re-ask’ the DHCP server for your DNS information   Then double check with:   Ipconfig /all   Do you see IPv4 DNS servers now?   Yes   Of course a reboot will work, but when you are troubleshooting DNS or DHCP you don’t want to reboot each time you try something.   Once you can ping security.local you can add your computer to the domain.         Other things to note – as you move from desktop support to administration, it’s important to…
