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.
