Earlier in the day, you created a user account for Brenda Cassini (bcassini). When she tries to log in, she can't. You realize t

hat you misspelled her username as bcasini. You are logged on as wadams, so you will have to address this issue as the root user. The root password is 1worm4b8. In this lab, your task is to: Change the user account name from bcasini to bcassini. Change the home directory to /home/bcassini. When you're finished, view the /etc/passwd file to verify the changes.

To what extent are the following computer systems instances of artificial intelligence:

Answer: Scanners used in supermarkets for barcodes and voice-activated phone menus are not examples of artificial intelligence.

Explanation:

(a) Supermarket barcode scanners can read codes, yet they lack the capability to employ machine learning techniques for learning patterns within the codes. Machine learning is a crucial aspect of artificial intelligence (AI), thus indicating they do not qualify as instances of AI. Likewise, voice-activated menus can only present options and do not carry out any complex tasks.

In contrast, web search engines and internet routing algorithms demonstrate dynamic and intelligent capabilities in processing and delivering information to users.

Hence, these are considered examples of AI.

Access-lists pose a logical problem which often has more than one solution. Can you think of a different set of rules or placeme

The question is incomplete, as it lacks a diagram of the topology and Router R1's table. I assume the user has access to both the topology and routing information. The configuration below will assist in resolving the ACL issue: Hosts within the 172.16.0.0/16 network should have unrestricted access to Server1, Server2, and Server3, which is currently not the case since L1 is unable to connect to Server2 or Server3. The suggested configuration on Cisco Router R1 will rectify the ACL issues.

A company operates on two types of servers: 2 large servers (L) and 4 smaller servers (S), with a combined total of 64GB RAM. Th

oksian1 [950]

Reasoning:

Let's denote the size of a large server as L and the size of a smaller server as S.

According to the data provided, we have two equations:

2L + 4S = 64.............(1)

and

L + 3S = 40...............(2)

To solve the equations, we proceed as follows:

2(2)-(1)

2L - 2L + 6S - 4S = 2*40 - 64

2S = 16

thus, S = 8..................(3), which indicates the size of the small server

Using (3) in (2) yields

L + 3(8) = 40

L = 40 - 24 = 16..............indicating the size of the large server

Answer:

The type of session hijacking attack that Sean is illustrating is Blind Hijacking, option C.

Explanation:

This is because he is inserting harmful data or commands into the compromised communications within the TCP session, regardless of the source-routing being turned off. He is capable of sending the data or commands, but does not have the ability to view the responses.
