Which encapsulation type is a Frame Relay encapsulation type that is supported by Cisco routers?

• A.ANSI Annex D
• B.IETF
• C.HDLC
• D.Q9333-A Annex A

Scenario
Refer to the topology. Your company has connected the routers R1, R2, and R3 with serial links.
R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also
connected to the routers R4 and R5.
The EIGRP routing protocol is configured.
You are required to troubleshoot and resolve the EIGRP issues between the various routers.
Use the appropriate show commands to troubleshoot the issues.





Which path does traffic take from R1 to R5?

• A.The traffic is unequally load-balanced over R2 and R3.
• B.The traffic is equally load-balanced over R2 and R3.
• C.The traffic goes through R3.
• D.The traffic goes through R2.

Which two tasks does the Dynamic Host Configuration Protocol perform? (Choose two.)

• A.Perform host discovery used DHCPDISCOVER message.
• B.Assign and renew IP address from the default pool.
• C.Provide an easy management of layer 3 devices.
• D.Configure IP address parameters from DHCP server to a host.
• E.Set the IP gateway to be used by the network.
• F.Monitor IP performance using the DHCP server.

CORRECT TEXT
A corporation wants to add security to its network. The requirements are:
-Host B should be able to use a web browser (HTTP) to access the Finance Web Server.
-Other types of access from host B to theFinance Web Server should be blocked.
-All access from hosts in the Core or local LAN to the Finance Web Server should be blocked.
-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 a numbered access list to a single outbound
interface. This access list can contain no more than three statements that meet these
requirements.
Access to the router CLI can be gained by clicking on the appropriate host.
-All passwords have been temporarily set to "cisco".
-The Core connection uses an IP address of 198.18.132.65.
-The computers in the Hosts LAN have been assigned addresses of 192.168.201.1 -
192.168.201.254. -host A 192.168.201.1 -host B 192.168.201.2 -host C 192.168.201.3 -host D 192.168.201.4 -The Finance Web Server has been assigned an address of 172.22.237.17. -The Public Web Server in the Server LAN has been assigned an addressof 172.22.237.18.

정답:

Please check the below explanation for all details.
Explanation:
We should create an access-list andapply it to the interface thatis connected to the Server LAN because it canfilter out traffic from both S2 and Core networks.To see which interface this is, use the "show ip interface brief" 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 B - 192.168125.2to theFinance Web Server 172.22.109.17 via HTTP(port 80), so our first line is this:
Corp1(config)#access-list 100 permit tcp host 192.168.125.2 host 172.22.109.17eq 80
Then, our next two instructions are these:
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 allhosts in the Core and onthe local LANaccesstothe PublicWeb Server (172.22.109.18)
Corp1(config)#access-list 100 permit ip host 172.22.109.18any
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 theLAN and the Core networks. To verify, just click on host Bto 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, Cand D) and check to make sure you can't 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 Topic 9, Mixed Questions
