Is it true Latency is measured by the round trip time it takes for a data packet to travel from source to destination and back to source?
What else can I help you with?
Define Network device latency?
Latency is the time a frame or a packet takes to travel from the source to the destination.
Is it true that when Latency is measured by the round-trip time it takes for a data packet to travel from source to destination and back to source?
Definition - What does Latency mean?Latency is a networking term to describe the total time it takes a data packet to travel from one node to another. In other contexts, when a data packet is transmitted and returned back to its source, the total time for the round trip is known as latency. Latency refers to time interval or delay when a system component is waiting for another system component to do something. This duration of time is called latency

Why is it that an ICMP packet does not have source and destination port?
Because ICMP is on the network layer
Where are ports recorded in an ip based packet?
It's recorded at the top of the IP packet header. 16 bit source and destination port.
What is the number known when you a packet source?
A number that is produced by a mathematical calculation on a packet at its source and checked against the same calculation at the destination is used as an error checking mechanism. What is this number known as?
What is packet marking?
If we are sending a file in one go and if some error occurred in between the file transfer then the complete file has to be resend which wastes the bandwidth so to prevent this, the file to send is divided in to smaller unit which we call packet, and then send packets 1 by one so that if a packet is lost then we need to send only that particular packet not the complete file. As the packet reaches its destination, the destination source send acknowledgement to the sender that the packet has reached to it and it may send the next packet and if packet somehow lost before reaching to the destination source, then the sender itself resends the packet after a fixed amount of time.

Which option sHow is the PDU that contains the Layer 3 source and destination addressing for a packet?
SLOT 0
During the encapsulation process what address is added?
During the encapsulation process, the destination and source IP addresses are added to the packet header. These addresses help routers and networking devices determine where to route the packet to reach its destination.
What is the role of the address field in a packet travelling through a datagram?
There are two address fields. Source is the IP address the packet came from and destination is the IP address the packet is meant to be delivered to.
On a Cisco router x IP lists check source packet addresses while y IP access lists check for both source and destination packet addresses?
x -> standard y -> extended
