Classic Case of Cisco Certified CCNA Comprehensive Experiment

Candidates who are familiar with Cisco Certification know that Cisco Certification requires comprehensive experimental questions, and CCNA is no exception.So SPOTO will tell you a classic case of Cisco CCNA Certification view online spoto training comprehensive experiment today.

Background Description of CCNA Comprehensive Experiment

let’s first take a look at the background description.The specific environment of an enterprise has the following five descriptions:

1. The enterprise has two office locations, which are far away. The company has about 200 hosts in total.

2. Office A has many departments, such as business department, finance department and general affairs department, which are the main office places. Therefore, the switching network in this part has high requirements for availability and reliability.

3. There are only a few office staff in Office B, but the Internet access point is there.

4. The company has only applied for a public IP address for intranet access.

5. Private network address is used within the company.

Network Topology of CCNA Comprehensive Experiment

The network topology is as follows:

Requirement of CCNA Comprehensive Experiment Case 

Specific comprehensive experiment setting steps will not be explained in detail. Let’s take a look at the requirements in this case first.

First, it should adopt a certain way to separate the broadcast domain.

Second, its core switch adopts high-performance three-layer switch, and adopts the situation that dual cores are backup to each other. The access layer switch is connected to two core switches through two uplink, and the three-layer switch realizes the routing between VLAN.

Third, its two core switches also adopt double link connection, and improve the link bandwidth between the core switches.

Fourth, the number of connections allowed on the access port of the access switch is 4, so as to improve the security of the network.

Fifth, layer 3 switchesconfigure routing interfaces to realize network wide interworking with RA and RB.

Sixth, RA and RB inOffice B is connected through WAN link, providing certain security.

Seventh, RB configures static routing to connect to the Internet.

Eighth, a public IP address is used on RB to access the intranet to the Internet.

Ninth, the access from the intranet to the Internet on the RB is under control. It is required that the finance department is not allowed to access the Internet. The business department can only access WWW and FTP services, while the general affairs department can only access WWW service, and the rest of the access is not under control.

After finding these needs, we can “suit the remedy to the case”. For example, according to the demand, one can divide VLAN on the switch, realize the separation of broadcast domains, divide VLAN 10 of business department, VLAN 20 of finance department and VLAN 30 of comprehensive department, and allocate interfaces. According to Requirement 6, PPP (point-to-point) protocol can be configured on the WAN interface of RA and RB, and PAP authentication can be used to improve security, Requirement 9 can be realized through ACL (access control list)
