Refer to the exhibit. Host A pings interface S0/0 on router 3. What is the TTL value for that ping?
A. 252
B. 253
C. 254
D. 255
Answer: B
Explanation:
From the CCNA ICND2 Exam book: “Routers decrement the TTL by 1 every time they forward a packet; if a router decrements the TTL to 0, it throws away the packet. This prevents packets from rotating forever.” I want to make it clear that before the router forwards a packet, the TTL is still remain the same. For example in the topology above, pings to S0/1 and S0/0 of Router 2 have the same TTL.

I agree with Bobo, it should be A!
s0/0 & s0/1 of router 2 have same ttl so final value is 253. Answer B is correct.
255-2=253
“B” is correct
A – 252 is correct!!!!
The question is when Host A pings interface s0/0 of router 3.
Therefore the packet has traversed only through two routers.
Hence Option B
B for sure.
