You are generating a derivatively classified piece of information and are looking for information in a classified database. While you are searching, you find a piece of information that is extremely helpful. It includes a banner line and a notice regarding the content only being marked at the highest level of classification within the database. Is this information authorized for use as a source of derivative classification?
a) yes
b) no
Answer:
No
Explanation:
The information without any authentic source including a banner line and a notice regarding the content only being marked at the highest level of classification within the database is not authorized for use as a source of derivative classification.
Answer:
Yes
Explanation:
The information can be safely use as alternative source of derivative classification. This is because the information is reliable. The reliability of the information comes from the fact that the sources are authentic and easily traceable. In addition, such information follows the highest standards of safety, such as encryption, safety protocols, URL checks, malware checks and many other security checks.
Compare and contrast if-else and elif statements. Give examples.
Explanation:
In coding, decisions are required only if certain conditions are fulfilled or met. If these conditions are met or not, the outcome should either be TRUE or FALSE before action of these statements is taken. An If else statement evaluates to FALSE when a Boolean expression is not met or is not true. Consider the snippet code below as an example
If 10==10
Print (10 is equal to 10)
Else:
Print (It is incorrect)
So, the above means that the program will evaluate to true if 10==10, and will print “It is incorrect” if another value is provided that evaluates to false
The elif statements, on the other hand, checks all conditions in your code and if one statement is TRUE, it will execute.
if 5.5 == int):
print("Value is Integer")
elif 5.6 == float):
print(“Value is Float”)
elif 5.5 == complex):
print("Value is Complex")
else:
print("Unknown")
Each condition is evaluated one after the other until a TRUE condition is found and evaluated. If all conditions happen to be FALSE, the else statement will be printed.
I have sampled a trumpet note and keymapped it to MIDI notes 55 to 65. If I play MIDI note 60 and hear middle C, what will I hear if I play MIDI note 62?
Answer:
The answer is D.
Explanation:
The musical interval between two notes depends on the ratio of their frequencies. An octave is a ratio of 2:1, an octave comprises 12 equal semitones. Each semitone therefore has a ratio of:
[tex]2^{\frac{1}{12} }[/tex]≈ 1.059
Then by convention, A4 is often set at 440 Hz and has MIDI note 69.
MIDI note 68 wich is one semitone below A4, that is, G#:
G#= [tex]\frac{440}{1.059}[/tex]=415.3 Hz
MIDI note 67 wich is one semitone below G#, that is, G:
G= [tex]\frac{415.3 }{1.059}[/tex]=392 Hz
MIDI note 66 wich is one semitone below G, that is, F#:
F#= [tex]\frac{392 }{1.059}[/tex]=369.9 Hz
MIDI note 65 wich is one semitone below F#, that is, F:
F= [tex]\frac{369.9 }{1.059}[/tex]=349.23 Hz
MIDI note 64 wich is one semitone below F, that is, E:
E= [tex]\frac{349.23 }{1.059}[/tex]=329.63 Hz
MIDI note 63 wich is one semitone below E, that is, D#:
D#= [tex]\frac{329.63 }{1.059}[/tex]=311.13 Hz
Therefore MIDI note 62 wich is one semitone below D#, that is,D:
D= [tex]\frac{311.13 }{1.059}[/tex]=293.6 Hz
Final answer:
If MIDI note 60 corresponds to middle C, then playing MIDI note 62 will result in the note D4, which is two semitones higher.
Explanation:
The student is asking about the relationship between MIDI notes and the pitches they represent. When a student plays MIDI note 60 and hears middle C, they are referencing the standard tuning where MIDI note 60 corresponds to middle C, which is 261.63 Hz (slight discrepancy from the 263 Hz mentioned, but both are commonly used to represent middle C). If the student then plays MIDI note 62 on the same key-mapped trumpet sample, they should expect to hear a note that is two semitones higher than middle C, which is the note D4.

7:58:40 SRC 10.254.254.1:3030, DST 10.254.254.10:80, ACK
Given the information, what can you infer about the network communications?
Answer:
What can be concluded from the above log is that; the router implements the Network Address Translation (NAT).
Explanation:
Network address translation (NAT) is a refers to the of remapping one IP address by enabling a private IP networks that use unregistered IP addresses to connect to the Internet.
This can be seen as allowing the router to repackage some packets so that the devices can have just one IP address.
As seen above, when the routes implements the NAT, the three networks were connected.
Which gives each network a private address so that packets can be sent to another network through their IP addresses

Your company has decided it wants to build a file server and store data that can be shared by coworkers. You were asked to research the type of storage that should be used on the server. Your boss said that he would like to implement RAID on the computer and wants your opinion on the best RAID type for the company. He informed you that the company will need at least 500 TB of storage. He also wants to make sure that if a drive fails, the data can be recovered. In addition, he told you to keep the cost down as much as possible. What will you recommend to your boss?
Answer:
RAID 5
Explanation:
One of the most common and best RAID configurations is the RAID 5. It is ideal for application and file servers with a restricted number of drives. RAID 5 is Considered as a good all-around RAID system in that it combines the better elements of efficiency and performance among the different RAID configurations.
Raid 5 is known to be fast, and reliable . It also offers cheap data redundancy and fault tolerance. Writes tend to be slower, due to the parity data calculation, but data can be accessed and read even when a failed drive is being rebuilt.
In a case of drive failure ,RAID 5 system can read the information contained on the other drives and recreate that data, accommodating a single drive failure.
In conclusion, the RAID 5 configuration is Cost Effective and has ability to recover from failures, thus it will be best option to be recommended tomy boss.
Final answer:
RAID 6 is recommended based on the need for at least 500 TB of storage, data recoverability from drive failures, and cost-effectiveness. It provides better data protection than RAID 5 and is more cost-effective than RAID 10, while maintaining the redundancy required for safe storage.
Explanation:
Considering the requirements of having at least 500 TB of storage, the necessity for data recovery in case of a drive failure, and the need to manage costs effectively, the RAID 6 configuration is recommended. RAID 6 provides fault tolerance by allowing up to two disk failures without data loss, which would give your company the redundancy needed to safeguard the stored data. While RAID 5 also provides fault tolerance, it only allows for a single drive failure, which might not provide enough protection for such a large data set. RAID 6, however, uses two parity blocks rather than one, giving it higher reliability.
It would require a minimum of 4 drives, and because of the dual parity, it would slightly reduce the total storage size available. However, this is a cost-effective solution compared to more expensive options like RAID 10, which offers great performance and redundancy but would require double the number of drives for the same usable storage space. When selecting drives for the RAID array, using enterprise-level hard drives is recommended as they are made for the rigors of continuous operation, which can extend the reliability and lifespan of your storage system.
You have been using the same computer for several years. To extend its service life, you decide to upgrade the processor. You check the motherboard documentation and purchase the fastest processor supported by the motherboard. However, when you start the computer, it beeps regularly, nothing is displayed on the screen, and it doesn't start. What should you do?A. Return the CPU for a new one.B. Update the UEFI firmware.C. Press F8 while booting the computer.D. Upgrade the motherboard.
Answer:
B. Update the UEFI firmware
Explanation:
UEFI (Unified Extensible Firmware Interface) is a standard firmware interface for PCs. It is responsible for waking up the computer hardware components and ensure they are functioning properly.
The old processor was controlled by an older version of the UEFI but to run the new processor, you update the Firmware Interface to enable it communicate with the computer's hardware components.

When you ran the computer, you noticed that the application was running very slow. After you exited the game and restarted it, you received an error message saying, "Insufficient memory or disk space." You checked your hard drive and saw that you had more than 250GB of free space.What should you check next in Task Manager?
Answer:
Performance tab - Memory available
Explanation:
Based on the scenario being described within the question it can be said that the next thing you should check in the task manager would be the memory available in the performance tab. This tells you the amount of RAM memory that certain applications are using. Sometimes applications such as games, may have a memory leak in the coding causing the game to take up an excess amount of memory to run, which would cause the game to crash.
Final answer:
The next step in troubleshooting the error message is to open Task Manager and check the memory usage of your system in both the 'Performance' and 'Processes' tabs to identify if RAM is fully utilized and if any applications are consuming too much memory.
Explanation:
When you encounter the error message 'Insufficient memory or disk space' despite having ample free hard drive space, the issue is likely related to RAM (Random Access Memory) and not storage space. The next step to troubleshoot in the Task Manager is to check the memory usage of your system. You can open Task Manager by pressing Ctrl + Shift + Esc or by right-clicking on the taskbar and selecting Task Manager.
Once opened, click on the 'Performance' tab to see if the RAM is being fully utilized. If it is, you may need to close some programs that are using a high amount of memory, or consider adding more RAM to your computer if possible. It can also be helpful to check the 'Processes' tab to see if any applications besides the game are consuming a disproportionate amount of memory.

An increasing concern for privacy and widespread availability of encryption products has led to the use of encryption for individual files and even entire devices. Briefly discuss the current state of encryption with respect to forensic investigation.
Answer:
As investigators, we are limited to the information on the device that we can access. If a hard drive is fully encrypted, we have no easy access to the stored data and our investigative options become limited. The first thing an investigator must do is to determine the level and extent of the encryption. Weak passwords can be cracked, but if the user has implemented a strong password it becomes almost impossible to access via brute force methods. It could be that just a few files are encrypted and there could be unencrypted copies elsewhere on the device. The user could also be a creature of habit and use the same set of passwords. These passwords can be quickly located in easily decipherable formats throughout the system. In all cases, though, I tell investigators that digital evidence is just one piece of the body of evidence in a case. Don’t fall into a trap where you spend too much time trying to decrypt a potentially probative item, when valuable unencrypted data may be found by simply continuing your examination
