CCNA Drag and Drop Questions 2

Here you will find answers to CCNA Drag and Drop Questions - Part 2

Question 1

The left describes OSI layers, while the right provides some terms. Drag the items on the right to the proper locations.

Answer:

Network Layer:

1) IP addresses
2) packets
3) routing

Transport Layer:

1) windowing
2) UDP
3) segments

Question 2

The above describes some categories, while the below provides their corresponding router output lines. Drag the above items to the proper locations.

Answer:

1) Port operational: Serial0/1 is up, line protocol is up
2) Layer 2 problem: Serial0/1 is up, line protocol is down
3) Layer 1 problem: Serial0/1 is down, line protocol is down
4) Port disabled: Serial0/1 is administrator down, line protocol is down

Explanation:

A simple way to find out which layer is having problem is to remember this rule: "the first statement is for Layer 1, the last statement is for Layer 2 and if Layer 1 is down then surely Layer 2 will be down too", so you have to check Layer 1 before checking Layer 2. For example, from the output "Serial0/1 is up, line protocol is down" we know that it is a layer 2 problem because the first statement (Serial0/1 is up) is good while the last statement (line protocol is down) is bad. For the statement "Serial0/1 is down, line protocol is down", both layers are down so the problem belongs to Layer 1.

There is only one special case with the statement ".... is administrator down, line protocol is down". In this case, we know that the port is currently disabled and shut down by the administrators.

Question 3

A user is unable to connect to the Internet. Based on the layered approach to troubleshooting and beginning with the lowest layer. Follow the guide and drag the contents to relevant modules.

Answer:

1) Verify Ethernet cable connection: Step 1
2) Verify NIC operation: Step 2
3) Verify IP configuration: Step 3
4) Verify URL: Step 4

Explanation:

The question asks us to "begin with the lowest layer" so we have to begin with Layer 1: verify physical connection; in this case an Ethernet cable connection. For your information, "verify Ethernet cable connection" means that we check if the type of connection (crossover, straight-through, rollover...) is correct, the RJ45 headers are plugged in, the signal on the cable is acceptable...

Next we "verify NIC operation". We do this by simply making a ping to the loopback interface 127.0.0.1. If it works then the NIC card (layer 1,2) and TCP/IP stack (layer 3) are working properly.

Verify IP configuration belongs to layer 3. For example, checking if the IP can be assignable for host, the PC's IP is in the same network with the gateway...

Verifying the URL by typing in your browser some popular websites like google.com, microsoft.com to assure that the far end server is not down (it sometimes make we think we can't access to the Internet). We are using a URL so this step belongs to layer 7 of the OSI model. 

Question 4

The left describes the types of cables, while the right describes the purposes of the cables. Drag the items on the left to the proper locations. (Not all items can be used).

Answer:

1) straight-through: switch access port to router
2) crossover: switch to switch
3) rollover: PC COM port to switch

Explanation:

To remember which type of cable you should use, follow these tips:

- To connect two serial interfaces of 2 routers we use serial cable
- To specify when we use crossover cable or straight-through cable, we should remember:
Group 1: Router, Host, Server
Group 2: Hub, Switch
One device in group 1 + One device in group 2: use straight-through cable
Two devices in the same group: use crossover cable

For example: we use straight-through cable to connect switch to router, switch to host, hub to host, hub to server... and we use crossover cable to connect switch to switch, switch to hub, router to router, host to host... )

Question 5

The left describes the types of switch ports, while the right describes the features. Drag the options on the right to the proper locations.

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
- Uses 802.1q to identify traffic from different VLANs
- Facilitates interVLAN communications when connected to a Layer 3 device

Question 6

The above describes the Spanning-Tree Protocol port states, while the below describes their functions. Drag the above items to the proper locations.

Answer:

- Learning: populating the MAC address table but not forwarding data frames
- Forwarding: sending and receiving data frames
- Listening: preparing to forward data frames without populating the MAC address table
- Blocking: preventing the use of looped paths

Hotspot Routing Question

Question 1:

If the router R1 has a packet with a destination address 192.168.1.255, what describes the operation of the network?

A - R1 will forward the packet out all interfaces
B - R1 will drop this packet because it is not a valid IP address
C - As R1 forwards the frame containing this packet, Sw-A will add 192.168.1.255 to its MAC table
D - R1 will encapsulate the packet in a frame with a destination MAC address of FF-FF-FF-FF-FF-FF
E - As R1 forwards the frame containing this packet, Sw-A will forward it ti the device assigned the IP address of 192.168.1.255

Answer: B

Question 2:

D - 255.255.255.252

Answer: A

Hotspot Frame-relay Question

(In the old days, this question was a multi-choice question but Cisco upgraded it into a lab-sim question. Therefore, instead of listing all the configuration as above, you have to type show frame-relay map and show running-config to get its configuration)

Question 1:

What destination Layer 2 address will be used in the frame header containing a packet for host 172.30.0.4?

A - 704
B - 196
C - 702
D - 344

Answer: C

Question 2:

A static map to the S-AMER location is required. Which command should be used to create this map?

A - frame-relay map ip 172.30.0.3 704 broadcast
B - frame-relay map ip 172.30.0.3 196 broadcast
C - frame-relay map ip 172.30.0.3 702 broadcast
D - frame-relay map ip 172.30.0.3 344 broadcast

Answer: B

Question 3:

Which connection uses the default encapsulation for serial interfaces on Cisco routers?

A - The serial connection to the MidEast branch office
B - The serial connection to the DeepSouth branch office
C - The serial connection to the NorthCentral branch office
D - The serial connection to the Multinational Core

Answer: A

Question 4:

If required, what password should be configured on the router in the MidEast branch office to allow a connection to be established with the Dubai router?

A - No password is required
B - Enable
C - Scr
D - Telnet
E - Console

Answer: D

Explanation:

This question is not clear for a long time but now maybe the trick was solved. What Cisco wants to ask is the word used as password, not the type of connection, so in the exam you might see some strange words for answers like "En8ble", "T1net", "C0nsole". All you have to do is to use the command "show running-config" as wx4 mentioned below to find the answer.  

wx4 commented:

Q4: if password required which?
in my example it was connection to North!

How to figure out which pw is required?

#show running-config

1. check the interface to the router you need connection to. If there is "ppp authentication" you need a password!

2. you will find the password on the top of your running-config output

check the area:

username North password c0nsole
username xxxxx yyyyy
username...

in my case it was c0nsole, in your case it can be no password needed or a different password.

If you are still not clear, please read anton's comment:

A big question I noticed here was about the FR Lab regarding the password. You have to perform a show running-config and look for USERNAME and PASSWORD.
i.e.
username South_Router password c0nsol3
username North_Router password t31net

Obviously this has to be en PPP encapsulation, if asked for a posible password for SOUTH_ROUTER you pick c0nsol3, and for NORTH_ROUTER you pick t31net. If you're running HDLC, i would pick "no password is requir
