Question 1 of 385

ACME corporation has decided to setup wireless (IEEE 802.11) network in it's sales branch at Tokyo and found that channels 1, 6, 9,11 are in use by the neighboring offices. Which is the BEST channel they can use?

Answer

Suggested Answer

The suggested answer is A.

Channels in the IEEE 802.11 wireless networks overlap with their adjacent channels. The non-overlapping channels usually utilized are 1, 6, and 11. Given that channels 1, 6, 9, and 11 are already in use, the best option would be channel 4 as it offers the least interference compared to others. It is far enough from channels 1, 6, and 11 to avoid significant overlap but still might slightly overlap with channel 6. Nonetheless, it presents the least interference among the given options.

Question 3 of 385

What is the MOST important document to obtain before beginning any penetration testing?

Answer

Suggested Answer

The suggested answer is D.

The most important document to obtain before beginning any penetration testing is a written statement of permission. This document serves as legal consent from the organization authorizing the penetration testing activities. It ensures that the testers are legally protected and outlines the boundaries and scope of the testing activities. Without this document, any testing could be considered unauthorized and illegal.

Question 4 of 385

While reviewing traffic from a tcpdump capture, you notice the following commands being sent from a remote system to one of your web servers:

C:\>sc winternet.host.com create ncservicebinpath- "c:\tools\ncexe -I -p 2222 -e cmd.exe"

C:\>sc vJnternet.host.com query ncservice.

What is the intent of the commands?

Answer

Suggested Answer

The suggested answer is A.

The first command creates a backdoor shell as a service. It uses 'sc' to create a service named 'ncservice' that will run 'ncexe' with parameters to start a listener on TCP port 2222 and execute cmd.exe. The second command queries the status of the created service to ensure it has been set up correctly.
