Answer:

iptables

Explanation:

On a Linux system, iptables command allows us to modify settings of the built-in packet filtering firewall.

Iptables is used to set up, maintain, inspect and update the tables of IP packet filtering rules on Linux.

For example,

  • To view the current rule settings we can use the command:

# iptables -L -n -v

  • To add new firewall rules:

# iptables -I INPUT <rule number> -s <source-ip address> -j DROP

A system with an availability of 99.999% can be down for a maximum of 52 minutes per year.
rjkz [21]
False. Just calculate what those five mins mean. And remember in percents so you have to divide by an extra 100

Five-nines or 99.999% availability means 5 minutes, 15 seconds or less of downtime in a year. Or, if you are really ambitious, shoot for six nines or 99.9999% availability, which allows 32 seconds or less downtime per year.

(10 points) [Edhesive] 3.6 Code Practice
Digiron [165]

Answer:

  • You need to create a variable outside (before) the input loop.
  • You need a variable inside your loop that temporarily holds the user input.
  • In your loop, you will compare if the variable outside the loop is greater than (or less than) the new user input.

I don't know what program language you are using, but I will use python since it's easy to read and you will get the idea if you're using a different programming language.

<u>Code (Python)</u>

largestnum = 0

for x in range(6): <em>#loops 6 times</em>

   newnum = int(input("Enter a number: ")) #ask user for input & converts to int.

   if newnum > largestnum: <em>#if new number is greater than largest num </em>

     largestnum = newnum     <em>#make it the largest number</em>

<em>    </em>print("Largest:", largestnum)

The reason why you need a variable outside of the loop is because after the loop is done all variables inside the loop are trashed and can no longer be accessed outside of the loop.

Why is stranded rather than solid cable used for patch cables? Why is it critical not to score the jacket too deeply when stripp
Serggg [28]

Answer:

The definition of the issues is listed throughout the section down.

Explanation:

  1. Stranded cables are somewhat more compact and can be mounted quickly. Strong cables become rigid in design, and they are not versatile for installation. In comparison with solid connectors, amplification is indeed high.
  2. Unless the innermost layer including its wire is broken as we attempt to connect the cable, it will not function. So, whenever stripping the cables through the walls, it's indeed important not to rank the jack too profoundly.
  3. It would be quick to untwist the cable and then will ensure that perhaps the connection is appropriate for the most widely encountered rj-45 connection whenever the wiring of 0.5 inches becomes coupled up.
  4. If we don't keep the right pin colors in order, the relation won't work. Afterward, when another connexon is broken due to many complications, it would be impossible to figure out the contacts unless the pins coloring are not always in sequence.
  5. The connection pairs can be cut off through 0.5 inches within about therefore the gap within the connector is narrower and the wire would not be correctly attached if we break the cable further. The link is lost and the cable does not run properly.
  6. It is necessary to ensure that perhaps the wires are forced to the end of the platform since the connexon will indeed be broken as well as the connector would not operate unless the wires aren't moved. The wires will fall out of another socket as well.
  7. Before even being incorporated into another crimping unit, it is good to carefully check the connection sequence to ensure that perhaps the wires are to the end since it is impossible to verify the sequence until the wires are attached to something like the connector. Unless the connections are not always in alignment, the link will also not be provided and indeed the wire would not operate correctly, even if the link is provided. Such wires can also be presented to use load barriers, and that it's the simplest operation.
  8. The Durability Tester has been used to determine the hardness between two stages, whereas the connection efficiency is tested using the qualification tester.
