I agree with Ernestine. C) Layer 3 source address is definitely overridden.

I’m leaning towards A) Three layers of TTL. It’s crucial for packet lifespan.

I feel like it’s C) Layer 3 source address. It changes when switching VLANs.

D) Layer 3 Transport Protocol seems off. It’s not about transport, just routing.

I feel like A) Three layers of TTL could be the answer too. TTL changes, right?

D) Layer 3 Transport Protocol seems irrelevant here. It's about addresses.

I remember practicing a similar question where we discussed TTL, but I can't recall if it's the three layers of TTL or something else.

I think the Layer 3 destination address might be overridden when packets are routed between VLANs, but I'm not entirely sure.
