Identify the spread spectrum technique that multiplies the original data signal with a pseudo random noise spreading code.
Answer: C
Katie has implemented the RAID level that splits data into blocks and evenly writes the data to multiple hard drives but does not provide data redundancy. This type of RAID level requires a minimum of __________ in order to setup.
Answer: A
The agency Jacob works for stores and transmits vast amounts of sensitive government data that cannot be compromised. Jacob has implemented Encapsulating Security Payload (ESP) to encrypt IP traffic. Jacob wants to encrypt the IP traffic by inserting the ESP header in the IP datagram before the transport layer protocol header. What mode of ESP does Jacob need to use to encrypt the IP traffic?
Answer: B
In tunnel mode, IPsec encrypts both the IP payload and the header to protect an entire IP packet by encapsulating it with an AH or ESP header and an additional IP header. This mode is useful for protecting traffic between different networks and is primarily used for interoperability with gateways. The tunnel mode of IPsec is generally implemented in configurations such as gateway-to-gateway, server-to-gateway and server-to-server. The IPsec tunnel mode is useful in protecting traffic while it is passing through untrusted networks.

Which of the following analyzes network traffic to trace specific transactions and can intercept and log traffic passing over a digital network? Each correct answer represents a complete solution. Choose all that apply.
Answer: AC
Protocol analyzer (also known as a network analyzer, packet analyzer or sniffer, or for particular types of networks, an Ethernet sniffer or wireless sniffer) is computer software or computer hardware that can intercept and log traffic passing over a digital network. As data streams flow across the network, the sniffer captures each packet and, if needed, decodes and analyzes its content according to the appropriate RFC or other specifications. Answer option D is incorrect. Performance Monitor is used to get statistical information about the hardware and software components of a server. Answer option B is incorrect. A spectrum analyzer, or spectral analyzer, is a device that is used to examine the spectral composition of an electrical, acoustic, or optical waveform. It may also measure the power spectrum.
Which of the following connects the SDN controller and SDN networking devices and relays information from network services to network devices such as switches and routers?
Answer: A
Which of the following is an example of MAC model?
Answer: D
The CNDv2 study guide only mentions two examples of MAC models: the Bell-LaPadula (BLM) model and the Biba integrity model. The Access Control Matrix is a DAC model, and the Chinese Wall model was developed to avoid COI issues but is not mentioned in the book.
