New Questions 5

CORRECT TEXTA corporation wants to add security to its network. The requirements are:

u2711 Host C should be able to use a web browser (HTTP) to access the Finance Web Server.

u2711 Other types of access from host C to the Finance Web Server should be blocked.

u2711 All access from hosts in the Core or local LAN to the Finance Web Server should be blocked.

u2711 All hosts in the Core and on local LAN should be able to access the Public Web Server.

You have been tasked to create and apply anumbered access listto a single outbound interface. This access list can contain no more thanthreestatements that meet these requirements.

Access to the router CLI can be gained by clicking on the appropriate host.

u2711 All passwords have been temporarily set to u201cciscou201d.

u2711 The Core connection uses an IP address of 198.18.209.65.

u2711 The computers in the Hosts LAN have been assigned addresses of 192.168.78.1 u2013 192.168.78.254.

u2711 host A 192.168.78.1

u2711 host B 192.168.78.2

u2711 host C 192.168.78.3

u2711 host D 192.168.78.4

u2711 The Finance Web Server has been assigned an address of 172.22.146.17.

u2711 The Public Web Server in the Server LAN has been assigned an address of 172.22.146.18.

Answer:

Please see below explanation part for details answer steps:

Explanation:

We should create an access-list and apply it to the interface that is connected to the Server LAN because it can filter out traffic from both S2 and Core networks. To see which interface this is, use the u201cshow ip int briefu201d command:

From this, we know that the servers are located on the fa0/1 interface, so we will place our numbered access list here in the outbound direction.

Corp1#configure terminal

Our access-list needs to allow host C u2013 192.168125.3 to the Finance Web Server 172.22.109.17 via HTTP (port 80), so our first line is this:

Corp1(config)#access-list 100 permit tcp host 192.168.125.3 host 172.22.109.17 eq 80

Then, our next two instructions are these:

u2711 Other types of access from host C to the Finance Web Server should be blocked.

u2711 All access from hosts in the Core or local LAN to the Finance Web Server should be blocked.

This can be accomplished with one command (which we need to do as our ACL needs to

be no more than 3 lines long), blocking all other access to the finance web server:

Corp1(config)#access-list 100 deny ip any host 172.22.109.17

Our last instruction is to allow all hosts in the Core and on the local LAN access to the Public Web Server (172.22.109.18)

Corp1(config)#access-list 100 permit ip host 172.22.109.18 any Finally, apply this access-list to Fa0/1 interface (outbound direction) Corp1(config)#interface fa0/1

Corp1(config-if)#ip access-group 100 out

Notice: We have to apply the access-list to Fa0/1 interface (not Fa0/0 interface) so that the access-list can filter traffic coming from both the LAN and the Core networks.

To verify, just click on host C to open its web browser. In the address box type http://172.22.109.17 to check if you are allowed to access Finance Web Server or not. If your configuration is correct then you can access it.

Click on other hosts (A, B and D) and check to make sure you canu2019t access Finance Web Server from these hosts. Then, repeat to make sure they can reach the public server at 172.22.109.18. Finally, save the configuration

Corp1(config-if)#end

Corp1#copy running-config startup-config

Which two statements about IPv4 multicast traffic are true? (Choose two.)

A. It burdens the source host without affecting remote hosts.

B. It uses a minimum amount of network bandwidth.

C. It is bandwidth-intensive.

D. It simultaneously delivers multiple streams of data.

E. It is the most efficient way to deliver data to multiple receivers.

Answer: B,E

Explanation: http://www.cisco.com/c/dam/en_us/about/ciscoitatwork/downloads/ciscoitatwork/pdf/ cisco_it_case_study_multicast.pdf

Cisco IOS IP Multicast in the Cisco Network

u201cIP Multicast as defined in RFC1112, the standard for IP Multicast across networks and the Internet, supports one-to-many content needs by delivering application-source traffic to multiple users without burdening the source or the network, using a minimum amount of network bandwidth. At the point where paths diverge, Cisco routers replace IP Multicast packets in the network, resulting in the most efficient delivery of data to multiple receivers.u201d Even low-bandwidth applications can benefit fro IP Multicast when there are thousands of receivers. High bandwidth applications, such as MPEG video, may need a large portion of the available network bandwidth for a single stream. In these applications, IP Multicast is the only way to efficiently send the same content to more than one receiver simultaneously, because it makes sure that only one copy of the data stream is sent across any one network link. It relies on each router in the stream to intelligently copy the data stream whenever it needs to deliver it to multiple receivers.
