Refer to the exhibit.
The network administrator normally establishes a Telnet session with the switch from host A.
However, host A is unavailable. The administrator’s attempt to telnet to the switch from host B
fails, but pings to the other two hosts are successful. What is the issue?
A.
Host B and the switch need to be in the same subnet.
B.
The switch interface connected to the router is down.
C.
Host B needs to be assigned an IP address in VLAN 1.
D.
The switch needs an appropriate default gateway assigned.
E.
The switch interfaces need the appropriate IP addresses assigned.
Explanation:
Ping was successful form host B to other hosts because of intervlan routing configured on router.
But to manage switch via telnet the VLAN32 on the switch needs to be configured interface vlan32
along with ip address and its appropriate default-gateway address.
Since VLAN1 interface is already configure on switch Host A was able to telnet switch.
Host A (172.19.1.1) and the management IP address of the Switch (172.19.1.250) are in the same subnet so telnet from host A to the switch can be successful even if a default gateway is not set on host A.
Although the switch has an IP address in Interface Vlan1 but it does not have a default gateway command pointing to the ip address on interface 172.19.1.254 -> B is correct.
Green I agree with the explanation but not your answer.
D is correct.
if PING works to the other two hosts (because THEY have DGW set) then Answer B CANNOT be correct…..I disagree with your answer, and the logic that leads you that direction.
the ONLY reason is does not work in this example is because the switch does not have a default gateway.
Dont Worry Guys “Green” Has Just Copied And Pasted The Answer From 9tuit:
The network administrator normally establishes a Telnet session with the switch from host A. The administrator’s attempt to establish a connect via Telnet to the switch from host B fails, but pings from host B to other two hosts are successful. What is the issue for this problem?
A. Host B and the switch need to be in the same subnet.
B. The switch needs an appropriate default gateway assigned.
C. The switch interface connected to the router is down.
D. Host B need to be assigned an IP address in vlan 1.
Answer: B
Explanation
Host A (172.19.1.1) and the management IP address of the Switch (172.19.1.250) are in the same subnet so telnet from host A to the switch can be successful even if a default gateway is not set on host A.
But host B (172.19.32.2) and the management IP address of the Switch (172.19.1.250) are not in the same subnet so host B needs a default gateway to telnet to the switch. The default gateway on host B should be 172.19.32.254.
So He Just Forgot That They’ve Changed The Order Of Answer Choices Here…!!!
Do Yes On This Page The Correct Answer Is “D” For Sure 😉
