Answer:
The blocking ping is not effective in an organization because it may required ping echo message from some trusted system. the best method will be to do the filtering of incoming echo ICMP messages.
In systems we have ping utility, that is based on ICMP protocol. Its function is to check the end to end connectivity of the system.
In this case a fist all an echo ICMP message is send to the host then host reply with ICMP message. to defend yourself from this flood attack, we need to filter the incoming echo ICMP packet messages. a net filter can be used to achieve it.
The best method be to applied is the firewall having a net filter with limit setting or any intrusion system. In market we have various firewall and intrusion system available to do so.
Explanation:
Solution
Ping Flood Atack:
In this attack the main of the attacker is to saturate the system with ICMP for example (internet control message protocol) traffic. as you have saturated the system, it will have less CPU time to serve others.
Defence against this attack:
In our systems we have ping utility, that is based on ICMP protocol. Its used to check the end to end connectivity of the system. here fist all an echo ICMP message is send to the host then host reply with ICMP message. to defend yourself from this flood attack , we need to filter the incoming echo ICMP packet messages. a Net filter can be used to achieve this.
The best way will be to used the firewall having net filter with limit setting or any intrusion system. In market we have various firewall and intrusion system available to do so.
Blocking ping packets to avoid ping flood attack:
Its not a good approach to block ping packets. because you may required ping echo message from some trusted system. The best option will be to do the filtering of incoming echo ICMP message.
Answer:
C
Explanation:
You can automatically cross out A, as they do not hinder communication. B can be crossed out as well, since kids should use these websites for help. Using the websites can be beneficial and give a learning edge. D is kind of correct, but isn't the best answer.
C is the answer because the websites are public data. People get on the website for help with certain concepts, and helps identify problems to their solution. <em>(Public data found on these forums provides widespread access to identified problems and their solutions.

Answer:
B. Send the packet out the Serial0/0/0 interface.
Explanation:
In order for packets to be sent to a remote destination, these three parameters must be configured on a host.
- Default gateway
- IP address
- Subnet mask
After a router successfully determines the destination network, the router checks the routing table for the resulting destination network number. If a match is found, the interface associated with the network number receives the packets. Else, the default gateway configured is used.
Also, If there is no default gateway, the packet is dropped.
Since the 192.168.12.227 network is not found in the routing table and the router uses the default gateway. The router then send the packet out the Serial0/0/0 interface which is the interface associated with the address 209.165.200.224/30.
Answer:
The answer to this question is "Principle of need to know".
Explanation:
In the given statement some information is missing that is the option of the question that can be described as follows:
A. Principle of least privilege
B. Principle of need to know
C. Principle of limited rights
D. Principle of permissions
The need to know principle refers to seeks to prevent "browsing" sensitive data by restricting access to as few people as possible. It is also known as a process, in which the user can set the restriction to access data to other users, and other choices are not correct that can be described as follows:
- In option A, It is used to access a critical system.
- In option B, It is used to provides rights to access data.
- In option D, It is also known as an administrator, that allows users to access data.
