the bonus.pkt is optional!

Are all the required files present?

Exercise 1:

Open the ex01.pkt file in Cisco PacketTracer.

Are the devices/links/IPs/netmasks in the solution similar to the required in the subject?

Check the communication between the PCs

• PC0 can communicate with PC1.
• PC2 can communicate with PC3.
• PC4 can communicate with PC5.

Can you confirm that the communications mentioned above are established?

Ask the following questions to the group or student

• What is a RJ-45 cable?
• What is difference between straight through and crossover RJ-45 cables?
• How are the IP addresses calculated?

Did the student reply correctly to the questions?

Exercise 2:

Open the ex02.pkt file in Cisco PacketTracer.

Are the devices/links/IPs/netmasks in the solution similar to the required in the subject?

Check the connections and communications.

Does all computers connected to the Switch must be connected?

Does all computers connected to the Hub must be connected?

Ask the following questions to the group or student

• What is the function of a switch, how does it operate and what is its role in networking?
• What is the function of a hub, how does it operate and what is its role in networking?
• What are the differences between a hub and a switch?
• Can you identify the OSI model layer that the switch and the hub operate on?

Did the student reply correctly to the questions?

Exercise 3:

Open the ex03.pkt file in Cisco PacketTracer.

Are the devices/links/IPs/netmasks in the solution similar to the required in the subject?

Can you confirm that all servers have static IP addresses?

###### Do all servers only provide the service specified for them?

Is the DHCP server responsible for assigning the IP addresses to all PCs?

Check the HTTPS Server.

Can you connect to the HTTPS Server from any PC in the network?

Does the HTTPS Server shows a "hell" message and is the HTTP disabled?

Check the FTP server.

Does a "deepinnet" user with RWDNL access exists in the FTP server?

Can you connect to the FTP server using the "deepinnet" user from any PC in the network?

Check the DNS server.

Confirm if the DNS server records are correct.

deep-in-net.local > 192.168.1.99
deep-in-net.com > deep-in-net.local

Does the DNS server contains the correct records as above?

Does "https://deep-in-net.com" redirects to the HTTPS Server?

Ask the following questions to the group or student:

• What is a server and what is its purpose in networking?
• How does DHCP work in a network and what is its function?
• What is the definition of DNS and what role does it play in network communication?
• What is the purpose of HTTP and how is it used in networking?
• What is HTTPS and how does it differ from HTTP?
• What is the purpose of FTP and how does it operate in network communication?
• What is TCP and UDP communication and what distinguishes them from each other?
• At which OSI model layer do TCP and UDP operate?
• What is a port in networking and what is its function?
• What are the port and OSI model layer for each protocol used?
• What are the various types of DNS records and what are their purposes?

Did the student reply correctly to the questions?

Exercise 4:

Open the ex04.pkt file in Cisco PacketTracer.

Are the devices/links/IPs/netmasks in the solution similar to the required in the subject?

Check the connections and communications.

Are the 2 PCs communicating with each other?

Ask the following questions to the group or student:

• What is a router and what is its role in a network?
• How does a switch differ from a router in terms of functionality?
• At which OSI model layer does a router operate?
• What is meant by the term "default gateway" in networking?

Did the student reply correctly to the questions?

Exercise 5:

Open the ex05.pkt file in Cisco PacketTracer.

Are the devices/links/IPs/netmasks in the solution similar to the required in the subject?

Check the connections and communications.

Are all devices connected to the same switch able to communicate with each other?

Are all devices in subnet 1 able to communicate with all devices in subnet 2 and vice versa?

Exercise 6:

Open the ex06.pkt file in Cisco PacketTracer.

Are the devices/links/IPs/netmasks in the solution similar to the required in the subject?

Check the connections and communications.

Is the PC in subnet 1 able to communicate with the PC in subnet 2 and vice versa?

Ask the student to explain what is a routing table and what is its role?

Did the student reply correctly to the question?

Exercise 7:

Open the ex07.pkt file in Cisco PacketTracer.

Are the devices/links/IPs/netmasks in the solution similar to the required in the subject?

Check the connections and communications.

Are all devices connected to the same switch able to communicate with each other?

Are all devices in subnet 1 able to communicate with all devices in subnet 2 and vice versa?

Ask the student to recreate the "Exercise 7" network again without external tools.

Was the student able to recreate the network?

Does the created network perform correctly?

Exercise 8:

Open the ex08.pkt file in Cisco PacketTracer.

Are the devices/links/IPs/netmasks in the solution similar to the required in the subject?

Check the connections and communications.

Are all devices connected to the same switch able to communicate with each other?

Can all devices in subnet 1 communicate with all devices in subnet 2 and vice versa?

Can all devices in subnet 1 communicate with all devices in subnet 3 and vice versa?

Can all devices in subnet 2 communicate with all devices in subnet 3 and vice versa?

Bonus:

+ Did the student pass the network recreation exam without error and in a short time?

+ Did the student add any optional bonus? If he did ask him what was it.

The auditor has the freedom to decide whether the bonus deserves to count or not!
