Sign = bit 32 = 0
Exponent = bits 24..31 = 10000101 = 133. Exponent is 133-127 = 6
Mantissa = bits 1..23 = 10110110101000000000000 = 5984256
is 1/2 + 1/8 + 1/6 + ...
resulting float value: 109.65625
Answer:
A and E
Explanation:
A Key Escrow is necessary when a third-party needs access to encrypted data, such as when there is a court order to decrypt the encrypted data. It involve the law giving the order to decrypt the encrypted data.
A Recovery Agent is a person/entity/role allowed to decrypt a user's data in case of emergency, such as when the original key is lost by the user. It is primarily for helping internal users
It is a class B network, so for a class B network, the upper 16 bits form the network address and the lower 16 bits are subnet and host fields. Of the lower 16 bits, most significant 4 bits are 1111. This leaves 12 bits for the host number. So, 4096(2^12) host address exists. First and last address are special so the maximum number of address is 4096-2=4094.

Answer:
B. Implement a key escrow.
Explanation:
A key escrow can be defined as a data security method of storing very essential cryptographic keys.
Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.
As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.
Hence, the cryptographic keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).
In this scenario, the Chief Information Officer (CIO) has determined the company's new public key infrastructure (PKI) will not use online certificate status protocol (OCSP). However, the purpose of online certificate status protocol (OCSP) still needs to be addressed. Thus, what should be implemented is a key escrow because the online certificate status protocol (OCSP) is an internet protocol used for maintaining the security of a server and obtaining a digital certificate that has been revoked.
