Answer:

The advisable course of action is A. Execute the reload command without saving the existing configuration.

Explanation:

Issuing the reload command is essential when facing network issues, as it can restore functionality to the switch or router without significant time expenditure.

In this particular instance, the technician made several alterations to the router's configuration, yet the issue remains unresolved. The most efficient way to proceed is to execute the reload command, omitting the current running configuration.

Answer:

alphabet = "abcdefghijklmnopqrstuvwxyz"

test_dups = ["zzz","dog","bookkeeper","subdermatoglyphic","subdermatoglyphics"]

test_miss = ["zzz","subdermatoglyphic","the quick brown fox jumps over the lazy dog"]

#Part 1 Construct a function, called has_duplicates, that takes a string argument and returns True if there are any repeating characters present. If not, it should return False.

def has_duplicates(stringP):

dic = histogram(stringP)

for key,value in dic.items():

if value>1:

return True

return False

# Execute has_duplicates by building a histogram using the above histogram function. Implement a loop over the items in the test_dups list.

# Display each string and indicate whether it has duplicates based on the has_duplicates function's result for that string.

# For instance, the expected output for "aaa" and "abc" would be shown below. aaa has duplicates abc has no duplicates Display a similar message for each string within test_dups.

print("***Implementation of has_duplicates function***")

for sTr in test_dups:

if has_duplicates(sTr):

print(sTr+": has duplicates")

else:

print(sTr+": has no duplicates")

#Part 2 Develop a function named missing_letters that takes a string argument and returns a new string containing all alphabet letters absent from the input string.

#The letters in the resultant string should be arranged in alphabetical order. Your implementation must utilize the histogram from the previous function and should reference the global alphabet variable directly.

#It should iterate over the alphabet letters to figure out which are missing from the input string.

#The function missing_letters should merge the list of missing letters into a string and return it.

def missing_letters(sTr):

missingLettersList = []

dic = histogram(sTr)

for l in alphabet:

if l not in dic:

missingLettersList.append(l)

missingLettersList.sort()

return "".join(missingLettersList)

#Iterate over the strings in the test_miss list and invoke missing_letters for each one. Present a line for each string outlining the missing letters.

#For example, for the string "aaa", the output should be as follows. aaa is missing letters bcdefghijklmnopqrstuvwxyz

#Should the string encompass all alphabet letters, the output should indicate that it utilizes all the letters.

#For instance, output for the alphabet string itself would be: abcdefghijklmnopqrstuvwxyz uses all the letters

#Generate a similar line for each item in test_miss.

print("\n***Implementation of missing_letters function***")

for lTm in test_miss:

sTr = missing_letters(lTm.replace(" ",""))

if sTr!="":

print(lTm+" is missing letters "+sTr)

else:

print(lTm +" uses all the letters")
