Refer to the exhibit. An engineer configures OSPF and wants to verify the configuration. Which configuration is applied to this device?
The exhibit indicates that the OSPF process is enabled by interface configuration. This is evident from the phrases 'Attached via Interface Enable' and 'Enabled by interface config'. The configuration that matches this description is configuring OSPF directly on the interface with the command 'ip ospf 1 area 0' under the interface configuration mode. Therefore, the correct configuration involves accessing the interface configuration mode, enabling OSPF on that interface, and ensuring the interface is not shut down, which corresponds to option C.
See the exhibit. It says "Attached via Interface Enable".
And if that wasn't enough, a little further down it says "Enabled by interface config"
C is the correct answer You can configure ospf two ways, Under global config: router osfp 1 network ip wildcard-mask >> Attached via Network Statement Under interface: inter gi0/2#ip ospf 1 area 0 >> Attached via Interface Enable
A. R1(config)#interface Gi0/1 R1(config-if)#ip ospf enable R1(contig-if)#ip ospf network broadcast R1(config-if)#no shutdown B. R1(config)#router ospf 1 R1(config-router)#network 0.0.0.0 0.0.0.0 area 0 R1(config-router)#no passive-interface Gi0/1 C. R1(config)#interface Gi0/1 R1(config-if)#ip ospf 1 area 0 R1(config-if)#no shutdown D. R1(config)#router ospf 1 R1(config-router)#network 192.168.50.0 0.0.0.255 area 0
C is the correct answer. The "show osfp interface gig0/1" output clearly shows the process is enabled by interface config.
This statement is Enabled by interface config
can anyone explain to me why not option A ? in exhibit it say network type Broadcast
C is correct
Voting: C.
C is correct
Attached via Interface Enable Enabled by interface config
Could go C or D. Since it a interface command. I say C as it refers to interface commands.

When you ue the "show ip ospf interface intx/x/x" command, what difference will you see in the old vs new OSPFv2 config? - One will say attached via Interface Enable, the other will say Attached via Network Statement https://www.chegg.com/flashcards/chapter-20-implementing-ospf-61b573b4-141b-4f63-bac9-ee35462d315e/deck
Once again a trick Q, or one based on other implied info. I am guessing the only reason 'C' is wrong, is somewhere in this output is an indication that the interface has been 'up' for some time - so the 'no shutdown' command was not needed.....
You are missing the interface enable from the output
It can't be A because ip ospf enable is not a legitimate command and also the ospf process number and Area 0 are missing
Sorry - I see it now: this interface has a secondary address , so have to use Network statement ???
Correct answer is C
