Explanation
CoPP protects the route processor on network devices by treating route processor resources as a separate entity with its own ingress interface (and in some implementations, egress also). CoPP is used to police traffic that is destined to the route processor of the router such as:
+ routing protocols like OSPF, EIGRP, or BGP.
+ Gateway redundancy protocols like HSRP, VRRP, or GLBP.
+ Network management protocols like telnet, SSH, SNMP, or RADIUS.

Therefore we must apply the CoPP to deal with SSH because it is in the
management plane. CoPP must be put under "control-plane" command.

JSON syntax structure: + uses curly braces {} to hold objects and square brackets [] to hold arrays + JSON data is written as key/value pairs + A key/value pair consists of a key (must be a string in double quotation marks ""), followed by a colon :, followed by a value. For example: "name":"John" + Each key must be unique + Values must be of type string, number, object, array, boolean or null + Multiple key/value within an object are separated by commas , JSON can use arrays. Arrays are used to store multiple values in a single variable. For example:
{
"name":"John",
"age":30,
"cars":[ "Ford", "BMW", "Fiat"]
}
In the above example, "cars" is an array which contains three values "Ford", "BMW" and "Fiat".
Note: Although our correct answer above does not have curly braces to hold objects but it is still the best choice here.
