Answer:
d. ICMP Echo Reply (type 0)
Explanation:
ICMP or internet control message protocol is an Internet layer protocol in the TCP/IP suite. It works together with routing devices like the router to send messages based on results sensed in the network.
The RFC 1122 has stated that the ICMP server and end user application be configured or installed in user devices, for receiving and sending ICMP echo request packets and reply. The process is called pinging.
For an attacker to implement ping of ping, he needs to confirm if the target user in live by sending an ICMP echo request packet type 8, to receive an ICMP echo reply type0.
Answer:
The recursion function is as follows:
def raise_to_power(num, power):
if power == 0:
return 1
elif power == 1:
return num
else:
return (num*raise_to_power(num, power-1))
Explanation:
This defines the function
def raise_to_power(num, power):
If power is 0, this returns 1
if power == 0:
return 1
If power is 1, this returns num
elif power == 1:
return num
If otherwise, it calculates the power recursively
else:
return (num*raise_to_power(num, power-1))
The answer is False.
According to research, a passive close doesn't lead your cover letter to have more interviews. In writing the closing part of your cover letter, it is easy to have a passive sentence but it sounds like less confidence to the employer. The last part of the cover letter should contain strong content to give an impression to the person who reads.
Answer:
Auto-negotiation protocol is the modern technology in the networking. This protocol allow the ethernet equipment for automate different instillation steps. This type of protocol use by interconnecting various electronic devices for negotiating the speed of the link.
Advantages:
- The auto negotiation protocol features used to maximize the throughput of data link layer.
- This protocol are basically useful in the local area network (LAN), with multiple capability of connections.
- The auto negotiation protocol extremely useful in twisted pair which are based on ethernet.
Disadvantages:
- This type of protocol are not fixed data links and not used as backbone of the networks.
- Duplex mismatch occur then, it cause significant loss in the packets.

True
