Which value, that is contained in an IPv4 header field, is decremented by each router that receives a packet?

  • Differentiated Services
  • Fragment Offset
  • Header Length
  • Time-to-Live

Explanation: When a router receives a packet, the router will decrement the Time-to-Live (TTL) field by one. When the field reaches zero, the receiving router will discard the packet and will send an ICMP Time Exceeded message to the sender.
