Answer:
b. The Hello timer as configured on the root switch.
Explanation:
There are differrent timers in a switch. The root switch is the only forwarding switch in a network, while non root switches blocks traffic to prevent looping of BPDUs in the network. Since the root switch is the only forwarding switch, all timing configuration comes from or is based on the configuration in the root.
The hello timer is no exception as the nonroot switch only sends 802.1D DTP hello BPDU messages forwarded to it by the root switch and its frequency depends on the root switch hello timer.
Answer:
Option D i.e., radiation is the correct answer.
Explanation:
When any person challenges the specific security system for the purpose of stealing the resources from the corporate security system then they unable to threaten the radiation because it is the electromagnetic waves that affect the body or skin of any human being and it can be generated by those devices that have high-voltage.
Answer:
Low sampling rate and low bit depth are the right options.
Explanation:
The low sampling rate and low bit depth can ensure less memory consumption. The musician here wants to record some initial ideas for some new song. And she is not concerned about the quality of the audio file she is going to send. And she wishes to send the size of the file that is as small as possible so that it can be quite easily downloaded by her bandmate. She can thus afford a low sampling rate and low bit depth, as the quality is not that important. And a low sampling rate and low bit depth can ensure less memory. Hence, these are the correct options here.
Answer:
<em>(c) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.</em>
<em />
Explanation:
Given
printAllCharacters method and printAllCharacters("ABCDEFG");
Required
What happens when x < str.length() is changed to x <= str.length()
First, we need to understand that str.length() gets the length of string "ABCDEFG"
There are 7 characters in "ABCDEFG".
So: str.length() = 7
The first character is at index 0 and the last is at index 6
Next, we need to simplify the loop:
for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)
The above loop will iterate from the character at the 0 index to the character at the 6th index
while
for (int x = 0; x<=str.length(); x++) means for (int x = 0; x<=7; x++)
The above loop will iterate from the character at the 0 index to the character at the 7th index
Because there is no character at the 7th index, the loop will return an error
Hence: (c) is correct
