Free Cisco CCNA 200-301 Actual Exam Questions - Question 13 Discussion
Refer to the exhibit. Inter-VLAN routing is configured on SW1. Client A is running Linux as an OS in
VLAN 10 with a default gateway IP 10.0.0.1 but cannot ping client B in VLAN 20 running Windows.
What action must be taken to verify that client A has the correct IP settings?
C. If the default gateway is wrong, client A won’t route traffic to VLAN 20 correctly. Checking it first makes sense before messing with IP or subnet mask details.
D imo, since checking the subnet mask with ifconfig can catch misconfigurations that stop proper routing. The mask has to match the VLAN's network for ping to work.
Option B makes sense because verifying both the IP address and subnet mask ensures client A is correctly configured within VLAN 10’s range, not just checking the gateway.
I think checking the default gateway is key here since client A can’t reach client B in a different VLAN. Option C suggests running ipconfig to confirm the default gateway is 10.0.0.1, which looks like the right step to verify if client A knows where to send traffic outside its subnet. The other options focus more on IP ranges or subnet masks but without the correct gateway, routing won’t work anyway. So I’d go with C.
We want to check client A’s IP setup, so running ifconfig to check IP and subnet seems right. Option B fits best.
