The vSmart controller performs the function of managing the control plane within the Cisco SD-WAN (Software-Defined Wide Area Network) environment. The control plane is responsible for making decisions about how traffic should be forwarded across the SD-WAN network.
On-premises infrastructure deployments have certain advantages over cloud infrastructure deployments, and one of them is lower latency between systems that are physically located near each other.
[value] is the proper syntax in JSON for an array. This indicates that each array is made up of a list of values that are enclosed in square brackets and are separated by commas.
The security model command set can be configured to enable data traffic encryption.
A FIB (Forwarding Information Base) and a RIB (Routing Information Base) are both components of a router used in computer networking to facilitate the forwarding of data packets.
In the event that the PC is unable to support 802.1X, the switch will maintain the PC's port in an unauthorized state and prevent data from flowing via the port. Not 802.1x, but port security is what shutdown has to do with as a response to a violation.
The noAuthNoPriv, authNoPriv, and authPriv security levels are supported by SNMP Version 3.

The statement regarding Cisco Express Forwarding (CEF) is true. CEF is a high-performance IP switching technology used in Cisco routers to improve the efficiency of packet forwarding.
The Quality of Service (QoS) component that modifies a packet to influence how network traffic is handled is called "marking."
In QoS implementation, packets are marked with specific values or tags in their headers to indicate their priority or class of service. These markings allow network devices, such as routers and switches, to identify and treat the packets differently based on their assigned priority. By modifying packets with appropriate markings, network administrators can control and prioritize the handling of different types of traffic to ensure that critical data receives better treatment and resources compared to less important traffic.
Distribution lists help prevent an autonomous system (AS) from functioning as a transit AS.
Network congestion can be alleviated by QoS (Quality of Service) traffic shaping through the use of packet buffering and queuing. When traffic shaping is implemented, it regulates the flow of packets to ensure that they adhere to specific bandwidth limits and priorities, which helps to manage network congestion
