A) is a commonly used symmetric encryption
<u>Explanation:</u>
DES stands for Data Encryption Standard. It is a symmetric key algorithm and is used for encrypting electronic data. It was developed in 1975. DES is one of the oldest encryption standards to be used in the industry.
The algorithm takes 16 rounds of permutations in order to encrypt data. But now, with the advent of technology, as new algorithms have been designed and put in use, DES is less preferable.
In the process of key generation, some keys generated sometimes turn out to be weak and hence are prone to attacks. If not for the weak keys generation, DES works perfectly fine and is an effective algorithm to encrypt data.

Hope this helped!
Answer:
d) All of the above
Explanation:
In configuration management, the Identify configuration items, work products and related components are present.
- All the documents which are related to the work,the manuals how that the system works are present in the configuration item identification.
- The source code that is implement for the functioning of the products.These are implemented at the time of generation of products.
- Software Requirement Specifications are also specified by SRS it is present in design stage of software development life cycle,it is also a part of configuration item identification.
1982 the Internet protocol was introduced as the standard network protocol on the ARPANET.
1981 access to the ARPANET was expanded.
