Answer:
MAC Addresses (Destination and Source MAC address)
Explanation:
A switch has 3 primary functions:
- Forward frames
- Learn addresses
- Avoid loops
An Ethernet frame has the header, data and trailer and there are two specific fields in the header that helps the switch to know where to send data in future transmissions.
- destination MAC address
- source MAC address
every Ethernet frame has this and when the frame hits a switch or any device, any device can look at it ( an Ethernet frame ) and know where it is suppose to go and where it came from.
Every switch has a MAC address table where it stores MAC addresses of different computers on the network.
Example:
When a PC1 sends a frame to PC2 through a switch, the switch looks at the header of the Ethernet frame for the source mac address and adds the source MAC address to its MAC address table and also the port that it came through.
simply put:
A switch looks at the source MAC address to see if it knows it already, if it does. Great! no need to add it again to it's address table.
If it doesn't, it adds it's source address and the port that the frame came from.
This basically how the switch populates its MAC address table.
Answer:
Explanation: What is that word you typed?
answer:
1.The program comes to a line of code containing a "function call".
2.The program enters the function (starts at the first line in the function code).
3.All instructions inside of the function are executed from top to bottom.
4.The program leaves the function and goes back to where it started from.
5.Any data computed and RETURNED by the function is used in place of the function in the original line of code.
Answer: CPU
Explanation:
The management dashboard refers to the tool that's used in the presentation of the vital k management KPIs in a single place, which is efficiently managed in order to make faster and better decisions.
Based on the information given, after the application of intrusion detection, virus, and malware protection on the Linux images, he will notices an increase in CPU on his server management dashboard.
Therefore, the correct option is C.
