Question 1

Explanation

CSMA/CD stands for Carrier Sense Multiple Access with Collision Detection. In an Ethernet LAN, before transmitting, a computer first listens to the network media. If the media is idle, the computer sends its data. If the media is not idle (another station is talking), the computer must wait for some time.

When a station transmits, the signal is referred to as a carrier. Carrier Sense means that before a station can send data onto an Ethernet wire, it have to listen to see if another “carrier” (of another station) is present. If another station is talking, this station will wait until there is no carrier present.

Multiple Access means that stations can access the network at any time. It is opposed to Token-Ring network where a station must have the “token” so that it can send data.

Although Carrier Sense help two stations not send data at the same time but sometimes two stations still send data at the same time! This is because two stations listen for network traffic, hear none, and transmit simultaneously -> a collision occurs and both stations must retransmit at some later time. Collision Detection is the ability of the media to detect collisions to know that they must retransmit.

Basically, the CSMA/CD algorithm can be summarized as follows:

+ A device that wants to send a frame must wait until the LAN is silent (no one is “talking”)
+ If a collision still occurs, the devices that caused the collision wait a random amount of time and then try to send data again.

Note: A switch separates each station into its own collision domain. It means that station can send data without worrying its data is collided with the data of other stations. It is as opposed to a hub which can cause collision between stations connected to it.

Question 2

Explanation

Only two commands “show interfaces” and “show ip interface brief” reveal the status of router interfaces (up/up, for example).

The outputs of two commands are shown below:

show_config_question_answer_2.jpg

show_ip_interface_brief.jpg

Question 3

Explanation

HTTP is based on TCP connection so a TCP connection must be established first between the workstation and the web server.

Question 4

Explanation

Hubs do not separate collision domains so if hub is used in the topology above, we will have only 1 collision domain. Switches do separate collision domains so if hubs are replaced by switches, we would have 22 collision domains (19 collision domains for hosts and 3 collision domains among three switches. Please notice that the WAN (serial) connection is not counted as a collision (or broadcast) domain.

Question 5

Explanation

A broadcast storm can cause congestion within a network. For more information about broadcast storm please read my STP tutorial.

Question 6

Explanation

Before a host can send ICMP (ping) packets to another device, it needs to learn the MAC address of the destination device so it first sends out an ARP Request. In fact, the first ping packet is dropped because the router cannot create a complete packet without learning the destination MAC address.

Question 7

Explanation

The “show running-config” command displays active configuration in memory.

Question 8

Question 9

Question 10

Explanation

Full-duplex communication allows both sending and receiving of data simultaneously. Switches provide full-duplex communication capability. Half-duplex communication only allows data transmission in only one direction at a time (either sending or receiving).

    Failed on 1-May with 800, retesting 7-June. This time I will incorporate Rob’s dump and see how I do. Only (1) LabSim and it was the DHCP one that is on here which is relatively easy – seemed like there was some new material but don’t remember much..

    June 17th, 2017

    Guys, probably ROB dumbs are ok. But for sure are not updated. There are too many questions about OSPF which is not on ICND1. So, probably are very old questions from the 100-101 exam. Or maybe are also some valid questions but is hard to say.

  49. beamy

    Rob’s dump has a massive amount of OSPF questions. OSPF was not in CCNA1 and CCNA2.

    Are there a massive amount of OSPF in the icend1-100-105 exam?

    regard to Q8, it is a bit funny,
    the question says “it does not have the destination address”.
    but the correct answer is :
    “Send out an ARP request with the destination IP address.”

    the only explanation is: the destination address in the question is the destination’s MAC address”

    I had the exam ICND 1 yesterday and I had a DHCP lab that totally threw me off. I could’nt get it working ,they had changed all the IP addresses and even though I carefully checked my IPs I could’nt fix the problem. I had used dumps from various sites. Lesson learnt is dumps are really good but never too rely totally on em. I will go in a month again but this time more practice. GL
