    CCNA 1 Module 1 Exam Solutions

    January 28th, 2008 • Related Filed Under

    Cisco’s exams can be a lot of hard work- we know. But the worst thing you can do to yourself

    is to simply look up the answers to exam questions. Not only do you not learn anything- but you’re hurting your future in the process.

    Instead, shouldn’t you get a helpful hint and get pointed in the right direction of where to look

    for an answer? That way, you can keep your dignity, hopes for the future, and of course your grade. The questions below are from the CCNA 1 module 1 exam- but instead of straight answers, we reason out why the answers are correct. If any type of math or decision making is involved, we leave that up to you (But we will of course give you the resources you need to complete the question.)

    1. Several computers in the company require new NICs. A technician has located a good price on the Internet for the purchase of these NICs. Before these NICs are purchased and installed, what details must be verified? (Choose three.)

    A) The MAC address on the NIC

    B) The size of the RAM on the NIC

    C) The bandwidth supported by the NIC

    D) The type of media supported by the NIC

    E) The type of network architecture supported by the NIC

    More info: What is a Network Interface Card?

    Explanation: After reading the material “What is a Network Interface Card,” we find out that a MAC address is unique to every NIC. Therefore, we don’t really have a need to be selective, and thus A is wrong. And NICs do have RAM, but it isn’t as vital to a NIC as it is for

    something like your computer- so B is wrong. The remaining three answers are therefore correct.

2. What is the hexadecimal equivalent for the binary number 00100101?

    A) 15

    B) 20

    C) 25

    D) 30

    Collected By Mohsen Yazarloo

E) 37

    F) 40

    More Info: A Guide to Network math

    Explanation: The above problem involves converting a binary number to a hexadecimal number. The above article explains that to do so, you need to split the binary number into two nibbles and then find their decimal value. After you find the decimal value, you may finally find the hex number. Consult the article above more a more in-depth explanation.

3. Which phrases describe a byte? (Choose two.)

    A) a single binary digit

    B) +5 volts of electricity

    C) the value range 0 to 127

    D) a grouping of eight binary digits

    E) a single addressable data storage location

    More Info: A Guide to Network math

    Explanation: From reading the above article, we know that one binary digit is a bit, not a byte- A is wrong. +5 volts of electricity may in some instances indicate a bit, but certainly not a byte- B is wrong. C is wrong because the value ranges from 0 to 255, not 127. Finally we get D and E as our answers- since we know that there are 8 bits in a byte, and each byte is considered to be a single addressable data storage location.

    4. Which specialized equipment is used to make a physical connection from a PC to a network?

    A) router

    B) RAM

    C) CD ROM

    D) network interface card

    More Info: What is a Network Interface Card?

    Explanation: You don’t necessarily need to read the above article to know this answer. RAM and CD-ROM components do not take a part in a network- and a router, like the name implies, routes data rather than connects a PC to a network. Obviously, the answer should be D.

5. What is the binary equivalent for the decimal number 248?

    A) 11100000

    B) 11110000

    C) 11110100

    D) 11111000

    More Info: A Guide to Network math

    Explanation: The above question wants you to convert the number 248 to binary. By reading the above article, we know that to do so we need to see which bits fit into 248. This is commonly done by the “Will this number go into 248?” method. If you need more of a descript explanation (complete with diagrams), consult the above article.

    6. Convert the binary number 01011011 into its hexadecimal equivalent. Select the correct answer from the list below.

    A) 5A

    B) 5B

    C) 5C

    D) 5D

    E) 6B

    F) 7A

    More Info: A Guide to Network math

    Explanation: The above problem involves converting a binary number to a hexadecimal number. The above article explains that to do so, you need to split the binary number into two nibbles and then find their decimal value. After you find the decimal value, you may finally find the hex number. Consult the article above more a more indepth explanation.

7. What is the binary equivalent for decimal number 149?

    A) 10010111

    B) 10010101

    C) 10011001

    Collected By Mohsen Yazarloo

D) 10010111

    E) 10101011

    F) 10101101

    More Info: A Guide to Network math

    Explanation: The above question wants you to convert the number 149 to binary. By reading the above article, we know that to do so we need to see which bits fit into 149. This is commonly done by the “Will this number go into 149?” method. If you need more of a descript explanation (complete with diagrams), consult the above article.

    8. In an 8 bit binary number, what is the total number of combinations of the eight bits? A) 128

    B) 254

    C) 255

    D) 256

    E) 512

    F) 1024

    More Info: A Guide to Network math

    Explanation: This question can be tricky. By reading the above article, we know that it is either 255 or 256. We know that we can go up to 255 with each byte of data. But don’t be so sure it’s C- it is, in fact, D. This is because we count 0 as a number, and thus, there are 256 combinations. Be on the lookout for more sly questions Cisco throws at us to make sure we’re

    still awake.

    9. Which device connects a computer with a telephone line by providing modulation and demodulation of incoming and outgoing data?

    A) NIC

    B) CSU/DSU

    C) router

    D) modem

    E) telco switch

    Collected By Mohsen Yazarloo

More Info: What is a Modem?

    Explanation: This question should be fairly easy. If you know the definition of a modem, you should get this question right even without our help. Nonetheless, the article above will provide extra information on modems if needed.

10. What is the binary equivalent for the decimal number 162?

    A) 10101010

    B) 10100010

    C) 10100100

    D) 10101101

    E) 10110000

    F) 10101100

    More Info: A Guide to Network math

    Explanation: The above question wants you to convert the number 162 to binary. By reading the above article, we know that to do so we need to see which bits fit into 162. This is commonly done by the “Will this number go into 162?” method. If you need more of a descript explanation (complete with diagrams), consult the above article.

    11. Which of the following are popular web browsers? (Choose two.) A) Acrobat

    B) Internet Explorer

    C) Macromedia Flash

    D) Netscape Navigator

    E) Quicktime

    F) World Wide Web

    More Info: (none)

    Explanation: This is another question that you should know from basic computer knowledge. Although we ourselves hesitated and asked, “Where’s FireFox, and why is Netscape

    Navigator on the list?” (It seems Cisco is a little behind on the times.)

    Collected By Mohsen Yazarloo

    12. Convert the Base 10 number 116 into its eight bit binary equivalent. Choose the correct answer from the following list:

    A) 01111010

    B) 01110010

    C) 01110100

    D) 01110110

    E) 01110111

    F) 01010110

    More Info: A Guide to Network math

    Explanation: The above question wants you to convert the number 116 to binary. By reading the above article, we know that to do so we need to see which bits fit into 116. This is commonly done by the “Will this number go into 116?” method. If you need more of a descript explanation (complete with diagrams), consult the above article.

    13. What is the hexadecimal equivalent for the binary number 10001110? A) 22

    B) 67

    C) 142

    D) AE

    E) 8E

    More Info: A Guide to Network math

    Explanation: The above problem involves converting a binary number to a hexadecimal number. The above article explains that to do so, you need to split the binary number into two nibbles and then find their decimal value. After you find the decimal value, you may finally find the hex number. Consult the article above more a more indepth explanation.

    14. Represented as a decimal number, what is the result of the logical ANDing of binary numbers 00100011 and 11111100?

    A) 3

    B) 32

    Collected By Mohsen Yazarloo

C) 35

    D) 220

    E) 255

    More Info: A Guide to Network math

    Explanation: This question involves the AND logical operator. Essentially, you compare the two binary numbers. If there is a binary 1 in the same location of both numbers, then you count that bit. Think of it as a test: you need 1 AND 1 for any addition to take place. A binary 1 and binary 0, or binary 0 and binary 0, will both not work. B is the correct answer since the 5th bit from the right is the only bit that can be ANDed- and 2^5 = 32. (Note that it is not the 6th bit, since we start counting at 0, not 1.)

    15. Convert the decimal number 231 into its binary equivalent. Select the correct answer from the list below.

    A) 11110010

    B) 11011011

    C) 11110110

    D) 11100111

    E) 11100101

    F) 11101110

    More Info: A Guide to Network math

    Explanation: The above question wants you to convert the number 231 to binary. By reading the above article, we know that to do so we need to see which bits fit into 231. This is commonly done by the “Will this number go into 231?” method. If you need more of a descript explanation (complete with diagrams), consult the above article.

    16. What are three conditions that would require a network administrator to install a new NIC? (Choose three.)

    A) whenever a NIC is damaged

    B) when there is a need to provide a secondary or backup NIC

    C) when there is a change from copper media to wireless

    D) whenever operating system security patches are applied

    Collected By Mohsen Yazarloo

E) whenever the PC has been moved to a different location

    More Info: What is a Network Interface Card?

    Explanation: A is correct since when something is broke, we should fix it (or in this case replace it). Obviously if we have the need for a backup NIC, we will need to install a new one- B is correct too. C is correct since some NICs are specific to a certain type of media, so changing that media warrants a new NIC. D is not true since the operating system does not have an effect on the NIC. E is not true because the physical location of a computer will not interfere with your NIC.

If any type of math or decision making is involved, we leave that up to you (But we will of course give you the resources you need to complete the question.)

    1. Which layer of the OSI model provides network services to processes in electronic mail and file transfer programs?

    A) data link

    B) transport

    C) network

    D) application

    More Info: An Introduction To The Tcp/Ip And OSI Model

    Explanation: This question is rather basic, and shouldn’t need much explaining. If you’re still lost or aren’t sure of the right answer, consult the above material for confirmation.

    2. Which of the following are data link layer encapsulation details? (Choose two.)

    Collected By Mohsen Yazarloo

A) A header and trailer are added.

    B) Data is converted into packets.

    C) Packets are packaged into frames.

    D) Frames are divided into segments.

    E) Packets are changed into bits for Internet travel.

    More Info: How Encapsulation Works Within the TCP/IP Model

    Explanation: Since each layer encapsulates the information with a header and trailer, A is correct. At the Data Link Layer, we do not convert the information into a packet- so B is wrong. Rather, we convert the packets into frames- so C is correct. D and E also incorrect since they do not follow the encapsulation process correctly- review the above material if you’d like a more thorough explanation.

3. Which three features apply to LAN connections? (Choose three.)

    A) operate using serial interfaces

    B) make network connection using a hub

    C) limited to operation over small geographic areas

    D) provide part-time connectivity to remote services

    E) typically operate under local administrative control

    F) provide lower bandwidth services compared to WANs

    More Info: The Difference Between LANs MANs And WANs

    Explanation: From reading the above article, we know that WANs use serial interfaces, not LANs, so A is incorrect. Since we can indeed make a network connection using a hub, B is correct. C is also correct- it corresponds with the exact definition of a LAN. D is incorrect, since LANs do not access remote services. E is correct, as it also corresponds with the definition of a LAN. F is incorrect since LANs provide much more bandwidth than WANs.

    4. Which layer of the OSI model provides connectivity and path selection between two end systems where routing occurs?

    A) physical layer

    B) data link layer

    Collected By Mohsen Yazarloo

C) network layer

    D) transport layer

    More Info: An Introduction To The Tcp/Ip And OSI Model

    Explanation: Path selection is not available on the physical layer- A is incorrect. The Data Link Layer provides an interface to the NIC, so B is incorrect as well. The Network Layer supports logical addressing and routing- and therefore, C is correct. The Transport Layer would be incorrect since it is responsible for and end-to-end connection, not necessarily path selection.

    5. Which term describes the process of adding headers to data as it moves down OSI layers?

    A) division

    B) encoding

    C) separation

    D) segmentation

    E) encapsulation

    More Info: How Encapsulation Works Within the TCP/IP Model

    Explanation: Division, encoding, separation, and segmentation all do not make sense in this instance. Logically, only encapsulation could be the correct answer. Follow the link above for more information on encapsulation.

    6. Refer to the following list. Choose the correct order of data encapsulation when a device sends information.

    1. segments

    2. bits

    3. packets

    4. data

    5. frames

    A) 1 3 5 4 2

    B) 2 1 3 5 4
