Question:
Which IP address is assigned to a network connection if the TCP/IP settings are set for static IP addressing and a DHCP server is running on the network?
A) An Automatic Private IP Addressing (APIPA) IP address is used
B) An error will occur and no IP address is assigned unless it is manually assigned at a command prompt
C) The IP address configured in the Internet Protocol Version 4 (TCP/IPv4) dialogue box is used
D) The IP address assigned by the DHCP server is used
Answer:
The correct answer is C
Explanation:
After the settings are changed from automatic to static, one must enter the address manually using the dialogue box and the spaces provided therein.
Any attempt to click okay will display an error requesting that the IP address be entered manually.
Static IP addresses are used when you don't want the Internet Protocol (IP) address to change.

The concept of a process in an operating system embodies two primary characteristics, one of which is:
Answer:
Resource Ownership and Scheduling execution
Explanation:
In process characteristic the characteristic is
Resource ownershipScheduling / ExecutionIn Resource ownership, the OS performs a protection function where unwanted interference in processes are with resources
In scheduling execution, the process has execution state and scheduled. They can be separated by resource ownership.
The dispatching of the process is the lightweight process, and it is multi-threading. The ability of the operating system supports the single concurrent process.
The process is a unit in the resource protection and protected the CPU and other processes. It contains the multiple thread execution
Each thread contains the running, ready state and saved the thread context and access the memory. Some necessary activities of the various threads are the same address space and the resources.
Define the term residential subscriber as it pertains to the telecommunications industry. Explain what is meant by the term rate center as it pertains to local telephone service. Who is responsible for determining the rate center boundaries for a calling region? Explain the difference between the terms rate center and wire center as they pertain to the local telephone serving area.
Answer:
According to section 40-15-102(18) of the Colorado Revised Statutes (CRS), a residential “Residential subscriber” is an individual who has elected to receive residential telephone service with a local exchange provider. The definition of “Person” here is extended to include any other persons living or residing with the residential subscriber.
A rate center is a geographical area used to define and organise the perimeter for local calling, for billing, and for assigning specific phone numbers, which can include multiple area codes.
The rate center boundaries are determined by Local Exchange Carriers (LEC)
LEC is just a regulatory jargon in the telecoms sector for the local telephone company.
A wire center is the actual physical telephone exchange building.
A rate center, on the other hand, is a regulatory concept designed with the primary goal to make billing administration within the local telephone serving area easy.

* Physical address in paired hexadecimal form.
* Physical address expressed in binary form.
Answer:
00000000 11111111 00000011 10111110 10001100 11011010
Explanation:
(i)First, open a command prompt window by using the shortcut: Windows key + X then select command prompt in the list.
(ii)Now type ipconfig/ all and press Enter. This will return a few information
(a) To get the Physical address in paired hexadecimal form, copy any of the Physical Addresses shown. E.g
00-FF-03-BE-8C-DA
This is the hexadecimal form of the physical address.
(b) Now let's convert the physical address into its binary form as follows;
To convert to binary from hexadecimal, we can use the following table;
Hex | Decimal | Binary
0 | 0 | 0000
1 | 1 | 0001
2 | 2 | 0010
3 | 3 | 0011
4 | 4 | 0100
5 | 5 | 0101

8 | 8 | 1000
9 | 9 | 1001
A | 10 | 1010
B | 11 | 1011
C | 12 | 1100
D | 13 | 1101
E | 14 | 1110
F | 15 | 1111
Now, from the table;
0 = 0000
0 = 0000
F = 1111
F = 1111
0 = 0000
3 = 0011
B = 1011
E = 1110
8 = 1000
C = 1100
D = 1101
A = 1010
Put together, 00-FF-03-BE-8C-DA becomes;
00000000 11111111 00000011 10111110 10001100 11011010
PS: Please make sure there is a space between ipconfig/ and all

Which of the following manages the flow of products through distribution centers and warehouses to ensure that products are delivered to the right locations in the most efficient manner?
A. Supply chain delivery system.
B. Supply chain demand system.
C. Supply chain execution system.
D. Internal supply chain system.
E. Supply chain planning system.
Answer:
C. Supply chain execution system.
Explanation:
In Business management, supply chain management can be defined as the effective and efficient management of the flow of goods and services as well as all of the production processes involved in the transformation of raw materials into finished products that meet the insatiable want and need of the consumers. Generally, the supply chain management involves all the activities associated with planning, execution and supply of finished goods and services to the consumers. The supply chain management is enhanced through the use of supply chain softwares.
Also the supply chain software can be classified into two (2) main categories and these are;
1. Supply chain planning system.
2. Supply chain execution system.
In this case, supply chain execution system manages the flow of products through distribution centers and warehouses to ensure that products are delivered to the right locations in the most efficient manner. There are various types of supply chain execution systems, these include;
1. Order fulfillment management system software.
2. Transport management system software.
3. Global trade management system software.
4. Warehouse management system software.
Hence, a supply chain execution system if effectively and efficiently used can be used to enhance final production, reverse distribution, distribution management, commitments, and replenishment.
4.Three years ago your company bought a new RAID 5 array. All the disks in the RAID were brand new, all manufactured within a month of each other. Today one disk has failed in this RAID. How many disks do you replace
Answer:
one disk
Explanation:
RAID 5:is an independent disks configuration of redundant array that utilizes disk striping in addition to parity. Data and parity bits are striped uniformly across the entire the disks configuration, so that no any single disk can create a bottleneck.
"Today one disk has failed in this RAID. How many disks do you replace"
Since RAID 5 guard against data through implementation of stripping of both data and parity bits, the failed disk can be replaced to restore the company's RAID 5 array fully back into service.
A security analyst is performing a BIA. The analyst notes that in a disaster, failover systems must be up and running within 30 minutes. The failover systems must use back up data that is no older than one hour. Which of the following should the analyst include in the business continuity plan?
A. A maximum MTTR of 30 minutes
B. A maximum MTBF of 30 minutes
C. A maximum RTO of 60 minutes
D. An SLA guarantee of 60 minutes
Answer:
D. A maximum RPO of 60 minutes
Explanation:
Note that an option is not included in this list of options.
The complete list of options is:
A. A maximum MTTR of 30 minutes
B. A maximum MTBF of 30 minutes
C. A maximum RTO of 60 minutes
D. A maximum RPO of 60 minutes
E. An SLA guarantee of 60 minutes
The Recovery Point Objective tells how old a backup file must be before it can be recovered by a system after failure.
Since the data in the failover systems described in this question must be backup and recovered after the failure, it will be important to include the Recovery Point Objective (RPO) in the Business Continuity Plan.
Since the failover systems must use back up data that is no older than one hour, the backup of the system data must be done at intervals of 60 minutes or less. Meaning that the maximum RPO is 60 minutes.
Note that RPO is more critical than RTO in data backup
What is the difference between requirements and controls in the security process? Give examples of each.
Answer:
Security controls are those measures taken to prevent, identify, counteract, and reduce security risks to computer systems, whereas, Security Requirements are guidelines or frameworks that stipulates measures to ensure security control.
Explanation:
Security controls encompass all the proactive measures taken to prevent a breach of the computer system by attackers. Security requirements are those security principles that need to be attained by a system before it can be certified as safe to use.
Security controls are of three types namely, management, operational, and technical controls. Examples of technical controls are firewalls and user authentication systems. A statement like 'The system shall apply load balancing', is a security requirement with an emphasis on availability.
Suppose you are provided with 2 strings to your program. Your task is to join the strings together so you get a single string with a space between the 2 original strings. This is a common case is coding and you will need to create your output by joining the inputs and adding the space in the middle.
# Input from the command line
import sys
string1 = sys.argv[1]
string2 = sys.argv[2]
Answer:
public class TestImport{
public static void main(String[] args) {
String string1 = args[1];
String string2 = args[2];
System.out.println(string1 +" " +string2);
}
}
Explanation:
The solution here is to use string concatenation as has been used in this statement System.out.println(string1 +" " +string2);
When this code is run from the command line and passed atleast three command line arguments for index 0,1,2 respectively, the print statment will return the second string (that is index1) and the third argument(that is index2) with a space in-between the two string.
You are an ISP. For the Address Block 195.200.0.0/16 a. If you have 320 Customers that need 128 addresses/customer - will there be enough addresses to satisfy them? and explain why? b. Say the first block of 64 customers want 128 addresses/customer - what would the address space look like?
Answer:
a. The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.
b. 195.200.0.0/22
Explanation:
195.200.0.0/16
The number of bits to give 512 is 9
2^9=512
2^8=256 which is not up to our expected 320 customers that requires a network ip
Note we have to use a bit number that is equal or higher than our required number of networks.
The number of host per each subnet of the network (195.200.0.0/25) is (2^7)-2= 128-2=126
The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.
b. 64 customers requires 6 bits to be taken from the host bit to the network bit
i.e 2^6 = 64
195.200.0.0/22
The number of host per each subnet of the network (195.200.0.0/22) is (2^10)-2=1024 - 2 = 1022 hosts per subnet
This network meet the requirement " 64 customers want 128 addresses/customer "
#Write a function called random_marks. random_marks should #take three parameters, all integers. It should return a #string. # #The first parameter represents how many apostrophes should #be in the string. The second parameter represents how many #quotation marks should be in the string. The third #parameter represents how many apostrophe-quotation mark #pairs should be in the string. # #For example, random_marks(3, 2, 3) would return this #string: #'''""'"'"'" # #Note that there are three apostrophes, then two quotation #marks, then three '" pairs. #Add your function here!
Answer:
def random_marks(apostrophe, quotation, apostrophe_quotation):
return "'"*apostrophe + "\""*quotation + "'\""*apostrophe_quotation
print(random_marks(3, 2, 3))
Explanation:
Create a function called random_marks that takes apostrophe, quotation, and apostrophe_quotation as parameters. Inside the function, return apostrophe sign times apostrophe plus quotation mark times quotation plus apostrophe sign quotation mark times apostrophe_quotation.
Note that plus sign (+) is used to concatenate strings. Also, if you multiply a string with a number, you get that number of strings ("#"*3 gives ###).
Then, call the function with given parameters and print

hard disk drive has 16 platters, 8192 cylinders, and 256 4KB sectors per track. The storage capacity of this disk drive is at most Select one: a. 32 GB. b. 128 GB. c. 128 TB. d. 32 TB.
Answer:
B
Explanation:
Here, we want to calculate the storage capacity of the disk drive.
We proceed as follows;
Per track capacity = 4 * 256 KB = 1024 KB = 1 MB
per platter capacity = 1 MB * 8192 = 8192 MB
total capacity = 16 * 8192 MB = 131072 MB
converting total capacity to GB,
1024 MB = 1 GB
thus, 131,072 MB to GB would be;
total capacity =131072/1024 = 128GB

A hard disk has four surfaces (that's top and bottom of two platters). Each track has 2,048 sectors and there are 131,072 (217) tracks per surface. A block holds 512 bytes. The disk is not "zoned." What is the total capacity of this disk
Answer:
128 GB
Explanation:
Here, we are interested in calculating the total capacity of the disk.
From the question, we can identify the following;
Number of surfaces = 4
Tracks per surface = 131,072
Number of sectors = 2,048
Each Block size = 512 bytes
Mathematically;
Total data capacity of the disk = no of tracks * no of sectors * block size
= 131,072 * 2048 * 512 bytes
= 2^17 * 2^11 * 2^9 bytes = 2^37 bytes
1 GB = 2^30 bytes
So 2^37 = 2^7 * 2^30
= 128 GB
True or False: It is okay to just paste the URLs of the items you used for references at the end of a paper. Select one: True False
It is not okay to just paste the URLs of the items you used for references at the end of a paper therefore the answer is False
For better understanding, lets explain why the answer is false
When citing a reference it not OK to cite URLs. when you are citing onlh the URL is wrong because theURL could change at any time and the fact remain that it is not everyone who reads your paper can do it electronically or has access to the internet., so the url is not the first step to take. The right thing to do is to give the name of the paper, the author(s), the Journal it was published in and the year it was published.
From the above, we can therefore say that the answer is It is not okay to just paste the URLs of the items you used for references at the end of a paper therefore the answer is False, is correct.

Write a statement that assigns total_coins with the sum of nickel_count and dime_count. Sample output for 100 nickels and 200 dimes is: 300
Answer:
total_coins = nickel_count + dime_count
Explanation:
The statement that performs the operation in the question is total_coins = nickel_count + dime_count
Full Program (Written in Python)
nickel_count = int(input("Nickel Count: "))
dime_count = int(input("Dime Count: "))
total_coins = nickel_count + dime_count
print("Total coins: ",total_coins)
The first two lines prompt user for nickel and dime count respectively
The third line adds the two coins categories together
The last line prints the total count of coins
The statement which gives the sum of nickel and dime is written below :
total_coins = nickel_count + dime_count
The statement required is written using Python 3 :
We could write these as a function :def total(nickel_count, dime_count) :
total_coins = dime_count + nickel_count
print(total_coins)
total(100, 200)
#the function total takes in two arguments(number of nickels and number of dimes)
#assigns the varibale total_coins to the sum of nickel_count and dime_count
We could also write this in the form of a program which prompts users to enter values :nickel_count = int(input('Enter count of nickel : '))
# User is prompted to enter number of nickels
dime_count = int(input('Enter count of dime : '))
# User is prompted to enter number of dimes
total_coins = nickel_count + dime_count
#assigns the varibale total_coins to the sum of nickel_count and dime_count
print(total_coins)
#outputs the value of total_coins

The main path of the Internet along which data travels the fastest is known as the Internet ________. Group of answer choices
Answer:
Internet backbone
Explanation:
The internet backbone is made up of multiple networks from multiple users. It is the central data route between interconnected computer networks and core routers of the Internet on the large scale. This backbone does not have a unique central control or policies, and is hosted by big government, research and academic institutes, commercial organisations etc. Although it is governed by the principle of settlement-free peering, in which providers privately negotiate interconnection agreements, moves have been made to ensure that no particular internet backbone provider grows too large as to dominate the backbone market.
The attack in which the attacker sends a fragmented message that the victim cannot reconstruct is a(n) ________ attack.
Answer:A teardrop attack
Explanation:
A teardrop attack also called denial-of-service attack is one which an attacker, usually a hacker sends many fragmented bug data messages to a victim's machine causing a crash in the device. This is because data moves in small data packets of whose transmission should follow layers according to the model of the devise be it OSI or TCP/IP model. Now when a hacker continually sends huge amounts of packets of bug data, the process of data transmission fails and packet data becomes overlapped, making the victim 's device machine in disarray and difficult to reconstruct while trying to rearrange them. When the hacker continually sends in more bug data packets to the already confused machine, The machine system crashes.
