The correct answer is "Have a higher strength per bit than an RSA". It is more difficult to compute Elliptic Curve discreet logarithms than conventional discreet logarithms or factoring. Smaller key sizes in the elliptic curve implementation can yield higher levels of security. Therefore, answer "Have a lower strength per bit than an
RSA" is incorrect.
Answers "Cannot be used to implement digital signatures" and "Cannot be used to implement encryption" are incorrect because elliptic curve cryptosystems can be used for digital signatures and encryption.

Explanation:
Because fiber-optic cable passes electrically non-conducting photons through a glass medium, it is immune to electromagnetic interference.
Incorrect Answers:
B: As an electromagnetic field carries the signal in the Coaxial cable, the signal can be affected by external inference.
C: As an electromagnetic field carries the signal in the Twisted Pair cable, the signal can be affected by external inference.
D: An axial cable is a coaxial cable with only one conductor instead of two conductors. Compared to a coaxial cable the axial cable is more vulnerable to electromagnetic interference.

Archive bit 1 = On (the archive bit is set).
Archive bit 0 = Off (the archive bit is NOT set).
When the archive bit is set to ON, it indicates a file that has changed and needs to be backed up. Differential backups backup all files changed since the last full. To do this, they don't change the archive bit value when they backup a file. Instead the differential let's the full backup make that change. An incremental only backs up data since the last incremental backup. Thus is does change the archive bit from 1 (On) to 0 (Off).
The following answers are incorrect:
Backs up data labeled with archive bit 1 and changes the data label to archive bit 0 - This is the behavior of an incremental backup, not a differential backup.
Backs up data labeled with archive bit 0 and leaves the data labeled as archive bit 0 - If the archive bit is set to 0 (Off), it will only be backed up via a Full backup. Everything else will ignore it.
Backs up data labeled with archive bit 0 and changes the data label to archive bit 1 - If the archive bit is set to 0 (Off), it will only be backed up via a Full backup. Everything else will ignore it.

The law that protects personally identifiable information (PII) used by financial services organizations is the Gramm-Leach-Bliley Act (GLBA). GLBA is a federal law that was enacted in 1999 to regulate the privacy and security of the financial information of the customers of financial institutions, such as banks, credit unions, insurance companies, or securities firms. GLBA requires financial institutions to provide their customers with a notice of their privacy policies and practices, and to obtain their consent before sharing their nonpublic personal information with third parties. GLBA also requires financial institutions to implement safeguards to protect the security, confidentiality, and integrity of the customer information, and to report any breaches or unauthorized access to the customers and the regulators. National Institute of Standards and Technology (NIST) SP 800-53 is a publication that provides a set of security and privacy controls for federal information systems and organizations, but it is not a law that protects PII used by financial services organizations.
Payment Card Industry Data Security Standard (PCI-DSS) is a standard that provides a set of security requirements for organizations that store, process, or transmit cardholder data, such as credit card or debit card information, but it is not a law that protects PII used by financial services organizations. Health Insurance Portability and Accountability Act (HIPAA) is a law that protects the privacy and security of the health information of the patients of health care providers, health plans, or health care clearinghouses, but it is not a law that protects PII used by financial services organizations.
