B. lst version of software
C. Design
D. Tested software -ANSWER-A
The type of disclosure process in which a new bug discovery is first
reported to the software vendor whose product contains the bug is
known as:
(a) Responsible Disclosure
(b) Full Disclosure
(c) Market Disclosure
(d) None of the above -ANSWER-A
Which of the following statements regarding Blockchain is NOT true?
(a) Blockchain is a list of records, called blocks, which are linked using
cryptography and are accessible for verification by the public.
(b) Blockchain is a distributed digital ledger in which transactions can
be recorded chronologically and publicly.
(c) Traditional databases also store transaction information
chronologically. But secure databases are kept under the centralized
control of a host organization and maintained by IT administrators.
,(d) Blockchain is designed as a centralized solution so that a single
entity can control it and validate all transactions. -ANSWER-D
Which of the following statements is NOT true?
(a) Ethereum is an example of a blockchain
(b) The cryptocurrency used in Ethereum are called Bitcoins
(c) Hyperledger is an example of open-source blockchain
(d) The cryptocurrency used in Ethereum are called Ethers -
ANSWER-B
Which of the following statements is true?
point
(a) In blockchains, any change or new transactions can be realized
only by adding a new block of information to the historical transaction
records.
(b) In blockchains, one doesn't erase or override the past records, it
adds transactions in a chronological order to a growing list.
(c) Unlike the ledgers maintained by banks, Bitcoin's blockchain is
replicated on networked machines around the world; hence it is called
a "Distributed Ledger".
(d) All of the above. -ANSWER-D
Which of the following is NOT true for Bitcoin mining?
point
(a) The technology uses a pair of keys for encryption
(b) The private key is used by the sender to encrypt the payment
message
(c) Miners use the sender's public key to validate that the payment
request was indeed made by the sender
(d) Miners will use the public key to compute the private key of the
sender -ANSWER-D
,Which of the following statement is true?
point
(a) The process of adding blocks to a blockchain is computationally
expensive, and even more so to change blocks further back in the
chain.
(b) Any miner trying to add a new block of data is required to provide a
cryptographic proof called Proof of Work.
(c) To produce the Proof of Work, a miner will have to perform multiple
rounds of hashing with the data of the previous block such that the
resultant hash value begins with a specified number of zeros.
(d) All of the above. -ANSWER-D
Which of the following is an application area for smart contracts?
point
(a) Supply chains are often inefficient because of paper-based
systems and need for multi-party approvals, validation cost, potential
for loss and fraud. Smart contracts can provide a secure, accessible
digital version to all parties on the blockchain to automate contracts
and payment.
(b) Peer-to-peer buying and selling of goods and services (e.g., in
electricity smart grids and ridesharing services) can benefit from smart
contracts executed between various parties participating in the
blockchain.
(c) Buyers and sellers of insurance can agree on and claim reparation
compensation using smart contracts.
(d) All of the above. -ANSWER-D
Suppose your organization needs multiple people to store and update
transaction records while ensuring immutability. Which one should you
choose?
point
, (a) Traditional database
(b) Block chain -ANSWER-B
Suppose the requirements that your organization has in regards to
storing transaction information can be met with either a traditional
database or a blockchain. Which one should you choose?
point
(a) Traditional database
(b) Blockchain -ANSWER-A
Suppose your organization needs to store transaction data that should
be kept private, immutable, verifiable, but also control who can read
and write to it in order to maintain scalability. What should you
choose?
point
(a) Traditional database
(b) Permissioned blockchain
(c) Public blockchain
(d) None of the above -ANSWER-B
Which of the following statements is true?
point
(a) A blockchain's technology and process ensure truthful-reporting
and provides incentives for participation.
(b) Cryptography principles implement validation of digital signatures,
security, and immutability in a blockchain.
(c) A blockchain's distributed realization and public accessibility helps
overcome censorship.
(d) All of the above. -ANSWER-D
Which of the following is very inflexible?
A. waterfall model
