FALSE Asymmetric encryption uses the same key to encrypt and decrypt a message. FALSE When using a digital signature for the process of authentication, the sender encrypts the message with their private key and the recipient decrypts the message with the sender's public key. TRUE
Secure Sockets Layer SSL is the latest cryptographic protocol designed to FALSE Websites can use TLS to secure all communications between their TRUE Public key cryptography uses a private key to encrypt a piece of data, and then the recipient uses the public key to decrypt the data. FALSE A risk assessment assigns levels of risk to various threats to network security by comparing the nature of the threats to the controls designed to reduce them. TRUE A(n) __________ is any potential adverse occurrence that can do harm, interrupt the system using the network to cause monetary loss to the organization. threat A ____________ is a situation in which a hacker attempts to disrupt the network by sending messages to the network that prevent normal users' messages from being processed. denial of service Anomaly detection compares network characteristics against TRUE IPS is a monitoring system, while IDS is a control system.

TRUE Warehouse-scale computers currently power the services offered by companies such as Google, Amazon, Facebook, and Microsoft's online services division. They differ significantly from traditional datacenters: they belong to a single organization, use a relatively homogeneous hardware and system software platform, and share a common systems management layer. TRUE The datacenters powering many of today's successful Internet services are simply a miscellaneous collection of machines co-located in a facility and wired up together. FALSE Achieving fault-free operation on a large collection of hardware and system software is made easier by the large number of servers involved. FALSE A Core Switch is a high-capacity switch positioned in the physical core, or backbone, of a network. In a fat tree, branches nearer the top of the hierarchy are thinner than branches further down the hierarchy. FALSE Interaction is carried out on a Blockchain using rules built into the program of the Blockchain called _________. Protocols Someone wanting to conduct a transaction using Cryptocurrency must send a message with the transaction signed with their private key. TRUE In addition to being a Turing-complete cryptocurrency, Bitcoin is a ledger technology that companies are using to build new programs. FALSE Using Blockchain technology, every node has a copy of the Blockchain. TRUE The implementation of specific protocols essentially made Blockchain what it is, a distributed, peer-to-peer and secured information database. Not every Bitcoin transaction is recorded on its blockchain.
