A network administrator is assigned the 172.16.0.0/24 block of addresses to use in designing an IP addressing scheme. The administrator submits this design for approval:
172.16.0.0/26
172.16.0.64/27
172.16.0.96/26
172.16.0.128/27
What should be the response from the senior network engineer regarding this design?
This design is flawed because the 172.16.0.128/27 network number is invalid.
This design is flawed because the 172.16.0.96/26 network overlaps with other addresses.
This design will work for the branch office.
This design is flawed because the 172.16.0.96/26 network is not a valid block of addresses.
This design is flawed because no design could have two networks that use a /26 mask and are not consecutive blocks of addresses.
Which statement describes a stateful firewall?
It can filter packets based on information at Layers 3, 4, 5 and 7 of the OSI reference model.
It can determine if the connection is in the initiation, data transfer, or termination phase.
It can only filter packets based on limited Layer 3 and 4 information.
It can expand the number of IP addresses available and can hide network addressing design.

Two network engineers are discussing the methods used to forward frames through a switch. What is an important concept related to the cut-through method of switching?
The fragment-free switching offers the lowest level of latency.
Fast-forward switching can be viewed as a compromise between store-and-forward switching and fragment-free switching.
Fragment-free switching is the typical cut-through method of switching.
Packets can be relayed with errors when fast-forward switching is used.
