Briefly describe how SNMP works.
What will be an ideal response?
The Simple Network Management Protocol (SNMP) is a protocol used to manage networked equipment. These devices include not only core network devices such as switches, routers, hubs, bridges, and wireless APs, but also printers, copiers, fax machines, and even uninterruptible power supplies (UPSs). Each SNMP-managed device must have an agent or a service that "listens" for commands and then executes them. These agents are protected with a password known as a community string in order to prevent unauthorized users from taking control over a device. There are two types of community strings: a read-only string will allow information from the agent to be viewed, and a read-write string allows settings to be changed.

Answer the following statement true (T) or false (F)
Suppose R1 is covered by 350 positive examples and 150 negative ex- amples, while R2 is covered by 300 positive examples and 50 negative examples. Compute the FOIL’s information gain for the rule R2 with respect to R1.
The RIPPER algorithm (by Cohen [1]) is an extension of an earlier algorithm
called IREP (by F ?urnkranz and Widmer [3]). Both algorithms apply the
reduced-error pruning method to determine whether a rule needs to be
pruned. The reduced error pruning method uses a validation set to estimate
the generalization error of a classifier. Consider the following pair of rules:
R2 is obtained by adding a new conjunct, B, to the left-hand side of R1. For
this question, you will be asked to determine whether R2 is preferred over
R1 from the perspectives of rule-growing and rule-pruning. To determine
whether a rule should be pruned, IREP computes the following measure:
where P is the total number of positive examples in the validation set, N is
the total number of negative exampl
