Subnetting pt2 + OSI Layers 5 to 7 | Week 3 lecture + readings Flashcards
If you were to split a network into 16 subnets (assume all subnets are usable). How many special addresses would there be in total under the new scheme? (note: special addresses are items like the Network ID and the broadcast IP Addresses)
32
If I were to have a /25 network (with 128 IP addresses (including the broadcast and the network ID)) and split it into 4 subnets… How many usable IP addresses would I have (assuming you can use all the subnets)?
120
On which Architecture would you expect the “server-side” to be doing most of the processes?
Host-based Architectures
There are 4 categories we covered in the lecture for the type of processing that could happen in application architectures
(Presentation Logic, Application Logic, Data Access Logic, and Data Storage Logic).
If you were to be told that a client is a “thin client”, where would you expect to see the application logic running?
mostly on the server-side
Of the choices below, which architecture approach would be the most “scalable”?
Client-Server based Architectures
Of the choices below, which would NOT be considered a layer 5, 6, or 7 protocol?
SSL
POP3
TCP or UDP
Ethernet
WIFI
HTTP
SMB
SMTP
IP
TCP or UDP
Ethernet
WiFi
and IP are not a layer 5,6,ot 7 protocol
In a network at my home, I have a router (network function) that is connected to a switch (network function), and the switch (network function) is also connected to 3 other desktop computers. How many collision domains would you expect there to be in this network?
4
In a network I have at home, I have a router (network function) with 5 connections. How many broadcast domains would you expect there to be on this network?
5
An IP header can be thought of like the outside of an envelope for a letter you are sending via Post.
In an IP V4 header, what data would be in the header?
flags, type of service, a TTL value, a destination IP address, IHL, fragment offset, source IP address, total length, header checksum, version
