ValentinkaMS [17]

The SOA is the specific record type found in every zone and contains information that identifies the sever primarily responsible for the zone as well as some operational properties for the zone.

Explanation:

The Start of Authority Records (SOA) has the following information they are

Serial Number: This number is used to find when zonal information should be replicated.

Responsible person: The Email address of a person is responsible for managing the zone.

Refresh Interval: It specifies how often a secondary DNS server tries to renew its zone information.

Retry Interval: It specifies the amount of time a secondary server waits before retrying the zone information has failed.

Expires After: IT specifies the amount of time before a secondary server considers its zone data if it can't contact with the primary server.

Minimum TTL: It specifies the default TTL value for a zone data when a TTL is not supplied.

sdas [7]

Answer:

import numpy as np

import matplotlib.pyplot as plt

def calculate_pi(x,y):

points_in_circle=0

for i in range(len(x)):

if np.sqrt(x[i]**2+y[i]**2)<=1:

points_in_circle+=1

pi_value=4*points_in_circle/len(x)

return pi_value

length=np.power(10,6)

x=np.random.rand(length)

y=np.random.rand(length)

pi=np.zeros(7)

sample_size=np.zeros(7)

for i in range(len(pi)):

xs=x[:np.power(10,i)]

ys=y[:np.power(10,i)]

sample_size[i]=len(xs)

pi_value=calculate_pi(xs,ys)

pi[i]=pi_value

print("The value of pi at different sample size is")

print(pi)

plt.plot(sample_size,np.abs(pi-np.pi))

plt.xscale('log')

plt.yscale('log')

plt.xlabel('sample size')

plt.ylabel('absolute error')

plt.title('Error Vs Sample Size')

plt.show()

Explanation:

The python program gets the sample size of circles and the areas and returns a plot of one against the other as a line plot. The numpy package is used to mathematically create the circle samples as a series of random numbers while matplotlib's pyplot is used to plot for the visual statistics of the features of the samples.

Answer: False

Explanation:

The statement that "Peacekeeper text is non-printing text that indicates where you can type" is false.

The non-printing text which shows where on exam type is referred to as the peaceholder text. It is usually an hint which can be used to fill in the actual text.
