A network technician observes that certain diagnostic packets used to monitor network connectivity are not reaching their destination within the corporate network. Which of the following options related to packet headers is a plausible explanation for the dropped or missing packets?
The destination devices are configured to reject all incoming diagnostic requests.
Security settings on a firewall are incorrectly blocking these diagnostic packet transmissions.
The network interface card on the sending system is outdated, causing transmission failures.
The Time to Live value of the packets decreases to zero before reaching their intended destination, leading to their disposal by intermediate routers.
