There are six categories of security services: authenticiation, access control, data confidentiality, data integrity, nonrepudiation, and availability service. First, is authentication service, which defines as the assurance that the communicator is legitimate and is the one that it claims to be. It can either be peer entity or data origin authentication. Second, access control which is to prevent any unauthorized uses of resources. After one is being authenticiated, then this service limit/controls who access? what accessing rights to the resources are allowed depending on the identified individuals. Data confifentiality: the protection of data from unauthorized disclosure. Data integrity: the assurance that data received are exactly as sent by an authorized entity (e.t.c, contain no modificafion, insertion, deletion, or replay).
I believe it’s problem solving.

Answer:
b. Synchronous replication
Explanation:
Replication of data in storage partitions or in a number redundant array of independent disk drives helps to promote redundancy, as implied, and faulty tolerance to reduce loss of data.
There are two categories of replication and they are synchronous and asynchronous replication.
Synchronous replication requires low latency network site to mirror data, while asynchronous replication mirrors data in large metropolitan area in high latency networks.
