Which of the following commands provide information on virtual memory, disk access, and CPU use?

networking

  1. vmstat

  2. stat

  3. ps

  4. uptime

Show answer
Correct Option: A

AI Explanation

To answer this question, you need to understand the different commands used to gather information about virtual memory, disk access, and CPU use. Let's go through each option to understand why it is correct or incorrect:

Option A) vmstat - This option is correct because vmstat is a command-line utility that provides information about virtual memory, including memory usage, paging activity, and swap usage. It also provides information about CPU usage and disk access statistics.

Option B) stat - This option is incorrect because the stat command is used to display file or file system status, such as file size, permissions, and timestamps. It does not provide information about virtual memory, disk access, or CPU use.

Option C) ps - This option is incorrect because the ps command is used to display information about active processes, including their process IDs, CPU usage, and memory usage. While it provides information about CPU use, it does not provide information about virtual memory or disk access.

Option D) uptime - This option is incorrect because the uptime command is used to display how long the system has been running and the current system load average. It does not provide information about virtual memory, disk access, or CPU use.

The correct answer is Option A) vmstat. This option is correct because vmstat provides information on virtual memory, disk access, and CPU use.

Authority for the internet rests with the ______.

networking

  1. ISOC

  2. IETF

  3. IAB

  4. IRSG

Show answer
Correct Option: A

AI Explanation

To answer this question, you need to understand the roles and responsibilities of various organizations involved in the governance and administration of the internet. Let's go through each option to understand why it is correct or incorrect:

Option A) ISOC (Internet Society) - This option is correct because ISOC is a global non-profit organization that provides leadership in internet-related standards, education, and policy. It promotes the open development, evolution, and use of the internet for the benefit of all people throughout the world.

Option B) IETF (Internet Engineering Task Force) - This option is incorrect because IETF is a large open international community of network designers, operators, vendors, and researchers concerned with the evolution of the internet architecture and the smooth operation of the internet. It focuses on the development and standardization of protocols used for internet communication.

Option C) IAB (Internet Architecture Board) - This option is incorrect because the IAB is a committee of the Internet Engineering Task Force (IETF) and provides architectural oversight of IETF activities. Its role is to oversee the development of internet standards and protocols, but it does not have authority over the entire internet.

Option D) IRSG (Internet Research Steering Group) - This option is incorrect because the IRSG is a group that focuses on the coordination of research activities related to the internet. It provides guidance and direction to the Internet Research Task Force (IRTF) and does not have authority over the entire internet.

The correct answer is A) ISOC. This option is correct because the Internet Society (ISOC) plays a significant role in the governance and administration of the internet, promoting its open development, standards, and policies.

Therefore, the correct answer is A) ISOC.

The number represented by 10111001 is an odd number.
networking

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

To solve this question, the user needs to know the concept of binary number representation and the parity of numbers.

In binary number representation, each digit can only be 0 or 1. The rightmost digit represents $2^0 = 1$, the second rightmost digit represents $2^1 = 2$, the third rightmost digit represents $2^2 = 4$, and so on. To get the decimal equivalent of a binary number, we add up the values of the digits that have a value of 1.

For the binary number 10111001, the decimal equivalent is:

$1\times2^7 + 0\times2^6 + 1\times2^5 + 1\times2^4 + 1\times2^3 + 0\times2^2 + 0\times2^1 + 1\times2^0$

$= 128 + 0 + 32 + 16 + 8 + 0 + 0 + 1$

$= 185$

To determine if 185 is an odd number, we can check if it is divisible by 2. If it is not divisible by 2, then it is an odd number.

185 is not divisible by 2, therefore it is an odd number.

The Answer is: A

In Windows NT, which program would you use to provide information on your system performance?

networking

  1. netstat

  2. Performance Monitor

  3. Network Monitor

  4. Optimize

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the different programs available in Windows NT and their purposes. Let's go through each option to understand why it is correct or incorrect:

Option A) netstat - This option is incorrect because netstat is a command-line tool used to display active network connections, routing tables, and network interface statistics. It does not provide information on system performance.

Option B) Performance Monitor - This option is correct. Performance Monitor is a program in Windows NT that allows you to monitor and analyze system performance. It provides real-time and historical data on various performance counters, such as CPU usage, memory usage, disk activity, and network activity.

Option C) Network Monitor - This option is incorrect. Network Monitor is a program used to capture and analyze network traffic. It is not specifically designed to provide information on system performance.

Option D) Optimize - This option is incorrect. Optimize is not a program in Windows NT specifically designed to provide information on system performance.

The correct answer is B) Performance Monitor. This option is correct because Performance Monitor is the program in Windows NT that provides information on system performance.
