Answer:

A) Like "9?????????"

Explanation:

Required

10 characters and starts with 9

<em>The options relate to queries in Microsoft Access; so, I will answer the question from the perspective of Microsoft Access.</em>

First, the query will use the like statement because the query is to make comparison.

Next; for the search query to return exact 10 characters, the syntax is "??????????"

Lastly, for the search query to begin with 9, the first ? will be replaced with 9.

So, we have: "9?????????"

<em>Hence, (a) is correct</em>

Paladinen [302]

Using an electronic signature on official documentation best illustrates the process of authentication

Further explanation:

The continuous rise of Electronic signatures has made it easier for people to accept signed documents by email or through electronic devices. One good example of electronic signatures is the implementation of digital signatures which broadly encompasses many types of electronic signatures out there. Digital signatures are unique to each signer and follow a standard authentication protocol called PKI. PKI use mathematical algorithms to generate what are known as private and public keys.

A good example is Bob and Jane. Jane sends an eSignature document using her private keys. Bob receives this document with an attached copy of Jane’s public key. The signature will be considered valid if the public key decrypts the signature correctly.
