Answer:
a. The cell tower forwards the call to the wireless provider's Mobile Telephone Switching Office
Explanation:
When a cell phone user begins to make a call, it is picked up by the cell tower located in the cell in which the cell phone is located and that belongs to the user's wireless provider. The next step in this process is that the cell tower forwards the call to the wireless provider's Mobile Telephone Switching Office.
Answer:
<em>The statement that describes a mobile device feature is docking stations can add some functionality to mobile devices such as video output.</em>
Explanation:
Because a docking station is a device that connects a mobile to multiple peripherals. It provides a single connection point that allows a mobile to function like a desktop computer.
According to its structure I'd say that this is SEAL (<span>Software-Optimized Encryption Algorithm). It's difficult to describe how it works, because this kind of ciphers is very tricky. This algorithm uses 160 bit key and it uses 3 tables (R, S, T) to encode and decode.
I'll attach the image where you can see a process of creating a pseudo-random function:

Answer:
A small company is requesting a quote to refresh its wireless network. The company currently runs 60 autonomous APs and has plans to increase wireless density by 50% in the near future. The requirements state that the chosen solution should significantly decrease the management overhead of the current wireless network. The following should be recommended by the vendor in response to the quote request:
B. The use of autonomous APs with a wireless controller.
Explanation:
- The option A and D are not correct as the use of lightweight APs are not required here because they are already using autonomous APs which are fulfilling their needs.
- The option B is correct as the use of autonomous APs with a wireless controller will allow them to decrease the management overhead as the wireless controller is used to manage the Access points in larger quantities.
- The option C is incorrect as the load balancers are used to increase the capacity and reliability of applications as they distribute the traffic over number of servers so it is unable to decrease the management overhead.
