Answer: Please see below as the answer is self-explanatory
Explanation:
In a telephone system, we call signaling to all signals that are originated within a telephony circuit, that are not part of the conversation between the calling parties.
We include in this broad category, the signal generated by the calling party when he picks up the phone, the call tone sent to him by the switch (or the busy tone if the call can't be established due to blocking), the digits that identify the called party, the ringing signal that informs the called party that someone is trying to reach him for a call, among others like are defined in the SS7 or the different 2G/3G/4G Cellular standards.
The importance of the signalling is pretty obvious; without these signals, it will be virtually impossible to set up a connection between the two parties.
Answer:
The correct answer to the following question will be Option C (Configuration management).
Explanation:
- A method of device engineering to create and maintain continuity of the functionality, operational and physical characteristics of software with its specifications, configuration and operating details across its existence.
- You will gain profit from:
Decreased risk of interruptions and data leaks through accessibility and keeping track of adjustments to your devices by implementing configuration management.
The remaining three solutions will not be capable of performing these functions. Therefore, the correct answer is alternative C Configuration management.
1. Tester should understand the vulnerability of the system because by this skill it should be able to secure the system for the parts where the attacks can be done.
2. Understand the web technologies and communication techniques of them because the two way communication understanding is one of the most important skill a tester should have so that he/she should have a proper image of what the system doing and how it is doing it.
3. Ability yo code scripts and most importantly understand them because while testing there are many script code to be read and understand for any bug or error the system is facing.

APPEND ONLY</h2>
Unlike traditional databases, blockchain is designed to be an "append-only" data structure. That means you can only append new data in the form of additional blocks, which will then be chained together with previous blocks of data. All data is permanently stored across more nodes and cannot be altered.
