Curious about this one.  Correct answer shown is.

Router OSPF 1
no passive-interface GigabitEthernet5

The description on Gi 5 shows it's connected to a switch.  I know descriptions can be wrong but question states it's connecting routers.

I know it says that no passive interface is unneccessary but wouldn't that fix it and also allow both gi 6 (which in description states it's connected to router) and Gi 5 both start working.

The wording makes it hard but I could see both answers getting the desired results so you are kind of questioning the description of the interface.

You correct answer is not a valid command.



exec commands is only for authorization and not authentication.

Great lab.  Had to change the ACL to do the testing for COPP.  I could not get a test from PC2.  This could be just due to me not being able to get it to ping properly with it being a virtual PC and not a router.

Changed ACL to any any and tested from R10 and verified the config.  I think the ACL is correct as shown I just couldn't get a test done properly from that device of PC20.

Task 1 show command results I think are wrong.

The neighbor ID is the router-id of R20 and not the interface IP.  Also priority should be 1 and not 0.  Also, address is 10.2.203.20 and not 10.2.203.2.



Task 2 is good.  I've recently had to learn this on a production environment.  Currently on a small project to switch from EIGRP to OSPF.

Provides for one-to-one communication should be a characteristic of Unique Local, not Global Unicast.

Thanks!

I believe two of your answers are inaccurate. Should be

[*]Extended service set (ESS)
➜ Wi‑Fi option in which cells from different access points are linked together
[*]Infrastructure mode
➜ Wi‑Fi option based around one or more access points
[*]Independent basic service set (IBSS)
➜ Wi‑Fi option that enables two or more clients to communicate directly without a central access point
[*]SSID
➜ Alphanumeric text string that identifies a wireless network
[*]Distribution system (DS)
➜ Entire wireless cell of an access point and the linkage to the wired network

The correct answer is missing the outside interface (for example g0/0) in the overload statement.

The "correct" answer is missing "lldp run" which is done globally. Without this command lldp will not run.

Please review the answer and correct accordingly.

Thanks!

"What is used to identify spurious DHCP servers?"

Answser should be DHCPOFFER

Not DHCPDISCOVER.

Please verify and correct accordingly.

Please review this question.

The answer I believe should be:

✔ Correct choice:
Responds to a request for IP address to domain name resolution to the DNS server.

Why the other options are incorrect

• “Serves requests over destination port 53.”
  ? This describes a technical detail of DNS transport (DNS typically uses port 53), not the lookup operation itself.
  
• “DNS server pings the destination to verify that it is available.”
  ❌ DNS does not ping hosts or check availability.
  
• “DNS server forwards the client to an alternate IP address when the primary IP is down.”
  ❌ This describes load balancing or failover behavior, not the fundamental DNS lookup process.
