SIMULATION -
Please wait while the virtual machine loads. Once loaded, you may proceed to the lab section. This may take a few minutes, and the wait time will not be deducted from your overall test time.
When the Next button is available, click it to access the lab section. In this section, you will perform a set of tasks in a live environment. While most functionality will be available to you as it would be in a live environment, some functionality (e.g., copy and paste, ability to navigate to external websites) will not be possible by design.
Scoring is based on the outcome of performing the tasks stated in the lab. In other words, it doesn't matter how you accomplish the task, if you successfully perform it, you will earn credit for that task.
Labs are not timed separately, and this exam may more than one lab that you must complete. You can use as much time as you would like to complete each lab.
But, you should manage your time appropriately to ensure that you are able to complete the lab(s) and all other sections of the exam in the time provided.
Please note that once you submit your work by clicking the Next button within a lab, you will NOT be able to return to the lab.

This one looks pretty easy. I'm assuming you may need to check ICMP on DC1's firewall to allow it to respond to ping requests. Just keep that in mind in case it doesn't respond to ping.

I think the first step would be: Go to DC1 Go to CMD type ipconfig check the ip address, remember it exit Now the next step would be: Go to Client3, Go to CMD type ipconfig enter ping the ip address of DC1 by using ping xxx.xxx.x.x exit Is this correct? I'm assuming it is. The answer provided didn't show you how you would know the ip address of DC1.

I think you should enable Echo Request - ICMPv4-In on DC first : Search for Windows Firewall , and click to open it. Click Advanced Settings on the left. From the left pane of the resulting window, click Inbound Rules. In the right pane, find the rules titled File and Printer Sharing (Echo Request - ICMPv4-In). Right-click each rule and choose Enable Rule.

I wouldn't waste my time on this question. So my fastest way would be ping -4 DC1 If I get the answer with the IP address in hand, then I ping back with that IPv4.

1. Check on both DC1 and Client3 Firewall settings for Echo Request - ICMPv4-In. 2. On Client 3 ping DC1 to get it's IP. 3. Ping DC1's IP again from Client 3... Voila !

You don't necessarily need to ipconfig on both, just DC. Then go into Client 3>Open CMD>Ping DC1 IP, no?

systeminfo in powershell or command prompt from client3 will show logon severs by host name. get-dnsclientcache will show ip address of logon servers from host record clear-dnsclientcache will clear dns If pings still fail. Then I would check firewall rules on both machines

On client3, open command prompt. ping -a DC1 will show the IP address of DC1, then ping that address.

There are also File & Printer Sharing (Echo Request - ICMPv4-In) too. The question doesn't ask you to ping the DC, it simply asks you to "ensure" that you can. The devices could be on different subnets and still ping each other if the route is known to the network. But if PING is blocked, as it is on many Servers, you may need to allow it through the firewall first.

use ping -4 <IP Address of DC1> to ensure your ping uses IPv4 instead of IPv6

No, that is not true. When you use PING and enter a ipv4 address, it will never ping over ipv6. So -4 or -6 is not needed because we are pinging on 172.x.x.x. You could use -4 or -6 if you ping on hostname, but that's not the question here.

where was IPv4 picked up from? I thought I would need to do nslookup dc01 and then ping based on the results.
