Worksheets9.1-9.2 Seminar
Total questions: 10
Worksheet time: 5mins
in Seminar 9.1, what role does the DNS server play in this activity?
It stores HTML files
It translates IP addresses into domain names
It resolves domain names to IP addresses
It blocks HTTP traffic
in Seminar 9.1, where can you view the HTML markup that creates the web page?
On the DNS server
In the Web Browser
In the Services tab > HTTP tab of the server
In the Simulation Panel
What protocol does HTTP rely on for communication?
UDP
TCP
ICMP
FTP
In seminar 9.1, what source port number is entered when creating the Complex PDU?
80
443
1000
8080
What does the “Buffer Full” window indicate during the simulation?
The network crashed
The event list reached capacity
The HTTP server is offline
The DNS request failed
Why does HTTP traffic generate many packets?
It uses UDP, which is unreliable
Each page element is stored on a separate server
TCP requires connection setup and acknowledgments
The browser reloads the page multiple times
Why is UDP considered faster than TCP in most cases?
It uses encryption
It does not require acknowledgments or connection setup
It compresses data
It has larger headers
Which protocol does the web server use to communicate with the client?
UDP
TCP
ICMP
ARP
in seminar 9.2, which devices are required for this topology?
Two PCs and a switch
One router, one switch, one PC, and one server
Two routers and two switches
One PC and one firewall
in seminar 9.2, what is the main purpose of this activity?
To compare DNS and HTTP
To explore how TCP and UDP perform at the transport layer
To configure VLANs and routing protocols
To analyze physical layer signals
