Drag and Drop Questions Flashcards
Question 1
Two offices are displayed below
You work as a network technician at 9tut.net. Study the exhibit carefully. The company has a main office in Los Angeles and a satellite office in Boston. The offices are connected through two Cisco routers. The Boston satellite office is connected through the R2 router s0 interface to the Los Angeles office R1 router s1 interface. R1 has two local area networks. Boston users receive Internet access through the R1 router. Drag the boxes on the top to complete the goal on the left.
Answer:
1) Prevent all users from outside the enterprise network from accessing the server: permit ip 192.168.35.0 0.0 0.255 host 192.168.35.66
2) Block a user from R1 e0 network from accessing the server: deny ip 192.168.35.55 0.0.0.0 host 192.168.35.66
3) Block only the users attached to the e0 interface of the R2 router from accessing the server: deny ip 192.168.35.16 0.0.0.15 host 192.168.35.66
Question 2
You are configuring the 9tut.net office. In particular the host C, with the IP address 192.168.125.34/27, needs to be configured so that it cannot access hosts outside its own subnet. You decide to use the following command:
access-list 100 deny protocol address mask any
You are required to fill in the protocol, address, and mask in this command using the choices below:
Answer:
1) protocol: ip
2) address: 192.168.125.34
3) mask: 0.0.0.0
Explanation
The syntax of extended access-list:
access-list 100-199 {permit|deny} {ip|tcp|udp|icmp} source source-mask [lt|gt|eq|neq] [source-port] destination dest-mask [lt|gt|eq|neq] [dest-port]
By telling the router to drop traffic originated from host C (source), we can guarantee that host C can just communicate with hosts inside its own subnet (because this kind of traffic does not need to pass the router and will not be prevented).
Question 3
Exhibit:
Router# show interfaces s1/0
Seria11/0 is up, line protocol is up
Hardware is CD2430 in sync mode
Internet address is 192.168.0.10/30
MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec, reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, LCP Open Open: CDPCP. IPCP, loopback not set
Last input 00:00:00, output 00:00:00, output hang never
Last clearing of “show interface” counters 4d21h
Study the exhibit carefully. You need to match output lines in the exhibit with the proper OSI layer. One line will not be used.
Answer:
Data Link Layer:
+ Encapsulation PPP
+ Line protocol is up
Physical Layer:
+ Serial 1/0 is up
+ Hardware is CD2430 in sync mode
Question 4
You work as a network administrator for your corporation, your boss is interested in switch ports. Match the options to the appropriate switch ports
Answer:
Access Port:
+ carries traffic for a single VLAN
+ uses a straight-through cable to connect a device
+ connects an end-user workstation to a switch
Trunk Port:
+ carries traffic for a multiple VLAN
+ Facilitates interVLAN communications when connected to a Layer 3 device
+ uses 802.1q to identify traffic from different VLANs
Question 5
Below is the configuration of the R1 router:
R1(config)# ip route 0.0.0.0 0.0.0.0 192.168.1.1
R1(config)# ip route 10.1.0.0 255.255.255.0 192.168.2.2
R1(config)# ip route 10.1.0.0 255.255.0.0 192.168.3.3
Drag each destination IP address on the top to its correct next hop address at the bottom.
Answer:
Next hop 192.168.1.1:
+ 10.2.1.3
+ 10.6.8.4
Next hop 192.168.2.2:
+ 10.1.0.14
+ 10.1.0.123
Next hop 192.168.3.3:
+ 10.1.1.10
+ 10.1.4.6
