The correct answer Token Ring. Token Ring is a LAN media access method, not a cabling type.

A business impact analysis (BIA) measures the effect of resource
loss and escalating losses over time in order to provide the entity
with reliable data upon which to base decisions on hazard
mitigation and continuity planning. A BIA is performed as one step
during the creation of a Business Continuity Plan (BCP). A common
five-step approach to a BCP could consist of:
BCP project scope creation
Business impact assessment
Recovery strategy development
Recovery plan development
Implementation, testing, and maintenance.
Answer a is a definition of a disaster/emergency management
program. Answer c describes a mutual aid agreement. Answer d is
the definition of a recovery program. Source: NFPA 1600 Standard

The proper order of steps in the emergency management planning
process is:
Establish a planning team
Analyze capabilities and hazards
Develop the plan
Implement the plan

Instead of using a shared-key to encrypt the hash of a given message, the sender's private key is used to encrypt the hash value of the message. This is the act of digitally signing the message.
Digital Signatures provide authentication of a sender and integrity of a sender's message.
A message is input into a hash function. Then the hash value is encrypted using the private key of the sender. The result of these two steps yields a digital signature. The receiver can verify the digital signature by decrypting the hash value using the signer's public key, then perform the same hash computation over the message, and then compare the hash values for an exact match. If the hash values are the same then the signature is valid.
The following answers are incorrect:
Having the sender encrypt the hash with his public key. This does not provide any benefit because only the sender cold decrypt using his own private key and nobody else.
Encrypting with a publick key only provide Confidentiality and not other service.
Having the sender encrypt the message with his private key. This is close but not good enough. It would only provide authenticity of the source.
Having the sender encrypt the message with his symmetric key. This would provide only
Confidentiality.

One of my student shared a tip with me on how to remember the classes of fire. He
said that he thinks about my first name to do so. More specifically the first four letters of my first
name which is CLEMent.
C stands for Common Combustible (CLASS A)
L stands for Liquid Fire (CLASS B)
E stands for Electrical Fire (CLASS C)
M stands for Metals that are burning (CLASS D)
Esha Oyarijivbie has shared another tip with me:
For another mnemonic: clem
klm Show verb (used with object), verb (used without object), clemmed, clemming. British Dialect
. to starve.
I think this is a very poignant way to remember the classes of fires being that you want to know the
difference in fires so that you can effectively "starve" the fire of its fuel.
