Which of the following can help to avoid problems with reused encryption keys? Select all that apply.
Group of answer choices
d) Combine the key with a nonce
c) Change the internal key
b) Clear your computer's RAM
a) Use the same passphrase
Answers
Using the same passphrase does not help in this context as reusing the same passphrase for encryption keys increases the vulnerability to attacks. a).
To avoid problems with reused encryption keys the following options can help:
Combine the key with a nonce:
A nonce (a number used only once) can be combined with the encryption key to generate unique ciphertext even if the same key is reused.
This adds an additional level of randomness and prevents attackers from identifying patterns.
Change the internal key:
Regularly changing the internal key used for encryption can help prevent problems with reused encryption keys.
By updating the key periodically the risk of key compromise or the ability to decrypt multiple messages decreases.
Clear your computer's RAM:
Clearing the computer's RAM (Random Access Memory) after the encryption process or when the keys are no longer needed can reduce the risk of key exposure.
RAM can retain sensitive data, including encryption keys even after the encryption operation is complete.
Clearing the RAM helps mitigate this risk.

T/F: in a data flow diagram (dfd), a process symbol can have only one outgoing data flow.
Answers
It is a false statement that in a data flow diagram (dfd), a process symbol can have only one outgoing data flow.
Can a process symbol have only one outgoing data flow?The process symbol in a DFD can have multiple outgoing data flows which represents a transformation or manipulation of data. Each outgoing data flow represents different output or result of the process.
But it is important to note that a process symbol should have at least one incoming data flow as it represents input to the process. So, it is recommended to limit the number of outgoing data flows to keep the diagram clear and easy to read.

Which of the following tripeptides carries a net positive charge at pH7.0 ? I. Gln-Val-Ser II. Ala-Thr-Asn III. Pro-lle-Leu IV. Leu-Lys-Gly V. Arg-Glu-Met
Answers
The tripeptide that carries a net positive charge at pH 7.0 is Leu-Lys-Gly (IV).
At pH 7.0, the carboxyl group of glutamic acid (Glu) in Arg-Glu-Met (V) and the carboxyl group of aspartic acid (Asp) in Ala-Thr-Asn (II) are deprotonated, resulting in a net negative charge. On the other hand, the side chain of lysine (Lys) in Leu-Lys-Gly (IV) has an amino group that can accept a proton at pH 7.0, resulting in a net positive charge. Therefore, out of the options given, Leu-Lys-Gly (IV) is the tripeptide that carries a net positive charge at pH 7.0.
Here is a summary:
- Gln-Val-Ser (I) does not contain any charged amino acids and therefore does not carry a net positive charge at pH 7.0.
- Ala-Thr-Asn (II) contains aspartic acid (Asp), which has a deprotonated carboxyl group and carries a net negative charge at pH 7.0.
- Pro-Ile-Leu (III) does not contain any charged amino acids and therefore does not carry a net positive charge at pH 7.0.
- Leu-Lys-Gly (IV) contains lysine (Lys), which has an amino group that can accept a proton at pH 7.0, resulting in a net positive charge.
- Arg-Glu-Met (V) contains glutamic acid (Glu), which has a deprotonated carboxyl group and carries a net negative charge at pH 7.0
So, the answer is option IV

If you have a collection of related attributes that can be considered a subtheme for one of the entities and you remove it, what form is the database now in?
A. Third normal
B. Second normal
C. Fourth normal
D. First normal
Answers
Answer:
If you have a collection of related attributes that can be considered a subtheme for one of the entities and you remove it, the form of the database is now in Second Normal Form (2NF).
Explanation:
In the Second Normal Form, the table is in 1st Normal Form and all non-key attributes are fully dependent on the primary key. It means that the table does not contain any partial dependency, which is when a non-key attribute is dependent on only a part of the primary key and not the entire key.
A database that is in 2NF has been stripped of all attributes that do not depend on the primary key, which is the subtheme that you have removed.
A database in third normal form (3NF) has no transitive dependency.
A database in fourth normal form (4NF) has no multi-valued dependency.
A database in first normal form (1NF) has no repeating groups.

increasing the sampling rate when digitizing a file has which effect on the file? (1 point) it decreases the file size it increases the file size it depends on the codec used to digitize the file it neither increases nor decreases the file size
Answers
Increasing the sampling rate when digitizing a file can increase the file size.
Why is this so?This is because the higher sampling rate captures more data per unit time, resulting in more data to store. The relationship between sampling rate and file size can be affected by various factors such as the bit depth, codec used, and compression settings.
However, in general, increasing the sampling rate will lead to larger file sizes. It is important to balance the benefits of higher quality audio or video against the storage and bandwidth requirements when choosing a sampling rate.

Explanation:
Shadow systems are frequently-seen departmental systems (usually spreadsheets) that the more technically inclined members of business groups create for their co-workers to use to gather and analyze data on their own when they do not want to work with IT or cannot wait for them.
Databases that are smaller than enterprise databases and focus on their creators' specific information requirements are known as shadow systems.
Shadow systems are created by individuals or departments within an organization to meet their own specific needs and requirements that are not addressed by the main enterprise database. These systems are not sanctioned by the IT department and are not managed or maintained by the organization.
Shadow systems can be problematic for organizations as they can lead to data duplication, inconsistencies, and security issues. They also do not integrate well with the main enterprise database, which can lead to data silos. Shadow systems can also create difficulties in data governance and compliance, as the data stored in these systems may not be subjected to the same standards and regulations as the enterprise database.
