Question 1

Question 2


Cisco Express Forwarding (CEF) provides the ability to switch packets through a device in a very quick and efficient way while also keeping the load on the router’s processor low. CEF is made up of two different main components: the Forwarding Information Base (FIB) and the Adjacency Table. These are automatically updated at the same time as the routing table.

The Forwarding Information Base (FIB) contains destination reachability information as well as next hop information. This information is then used by the router to make forwarding decisions. The FIB allows for very efficient and easy lookups.

The adjacency table is tasked with maintaining the layer 2 next-hop information for the FIB.

Question 3


A late collision is defined as any collision that occurs after the first 512 bits of the frame have been transmitted. The usual possible causes are full-duplex/half-duplex mismatch, exceeded Ethernet cable length limits, or defective hardware such as incorrect cabling, non-compliant number of hubs in the network, or a bad NIC.

Note: On an Ethernet connection, a duplex mismatch is a condition where two connected devices operate in different duplex modes, that is, one operates in half duplex while the other one operates in full duplex.

Question 4

Question 5


The ping command first sends an echo request packet to an address, then waits for an echo reply. The ping is successful only if:
+ The echo request gets to the destination, and
+ The destination is able to get an echo reply back to the source within a predetermined time called a timeout. The default value of this timeout is two seconds on Cisco routers.

Reference: http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-software-releases-121-mainline/12778-ping-traceroute.html

Question 6


There are many options to choose when using extended ping. Below shows the options that we can choose:


In which:

+ Repeat count [5]: Number of ping packets that are sent to the destination address. The default is 5 -> A is correct.
+ Source address or interface: The interface or IP address of the router to use as a source address for the probes -> B is correct.

For more information about extended ping, please read: http://www.cisco.com/c/en/us/support/docs/ip/routing-information-protocol-rip/13730-ext-ping-trace.html

Question 7


We are not sure about this question. But below is information about the shadowed rule for your reference.

Shadowed Rule: These are rules that will never be executed because of improper access-list order. A shadowed rule occurs when a general rule precedes a specific one. For example, if the first rule that says “allow all outbound web traffic” and then a second rule (lie under the first rule) says “deny all outbound traffic to Google” the second rule will never be executed.

The following is a simple example of shadowed rules:

access-list acl permit ip any
access-list acl permit ip any

-> The second rule never matches.

Question 8

Question 9


The “show users” shows telnet/ssh connections to your router while “show sessions” shows telnet/ssh connections from your router (to other devices). The question asks about “your active Telnet connections”, meaning connections from your router so the answer should be A.

Question 10

Question 11

    a the Qos byte
    b the Cos byte
    c the Tos byte

    packet, I’m almost certain it’s C, Type of Service byte.

    in which byte of an ip packet can traffic be marked?

    Answer correct “D”

    QoS = Prioritization of traffic marked on router and IP Backbone;
    CoS = Prioritization of traffic marked in Switches and Datacenter Switches;
    ToS = Are the types of files marked (VOICE, DATA, VIDEO).
    DSCP = Responsible for performing package markup.

    in which byte of an ip packet can traffic be marked?

    Correct Answer is TOS Byte.

    QoS = Prioritization of traffic marked on router and IP Backbone;
    CoS = Prioritization of traffic marked in Switches and Datacenter Switches;
    ToS = Are the types of files marked (VOICE, DATA, VIDEO).
    DSCP = Responsible for performing package markup.

    Though the above explanations are correct DSCP is not a Byte (it’s only 6 bits, a sub-group of a TOS byte)

    TOS(8 bits) = DSCP (6 bits)+Unused (2 bits)

    Can you please share link on where to download VCE so I can load the dumps?

  20. Das
    March 1st, 2018

    The answer should be TOS. Because DSCP is 6 bits. And TOS is 8 bits which is 1 byte.

  21. CCNA

    Number 9 should be C
    please correct the pdf

    Which command shows your active Telnet connections?
    A. show sessions

    @ccna “show users” shows list of all accounts, question is about active accounts

    Regarding Q7, please refer to the following question from the SDN topic:

    Question 4

    Question: Which utility can you use to identify redundant or shadow rules?
    Answer: The ACL analysis tool in Cisco APIC-EM.

    Please check again and if agree with it then recitfy.

    QUESTION 280
    In which two situations should you use out-of-band management?
    A. when a network device fails to forward packets
    B. when you require ROMMON access
    C. when management applications need concurrent access to the device
    D. when you require administrator access from multiple locations
    E. when the control plane fails to respond
    Correct Answer: AB

    Can someone please explain why A and B are correct answers and what about C and E ?

  26. Dany1
    June 30th, 2018

    PrincipO : C is not correct, because management applications have concurrent access through vty lines (0-4 or 0-15; check with show line; many concurrent connections )
    D: administration access from multiple location is easy to be done using in-band method
    Out-band is using when admin loose in-band connectivity or is possible to loose,after some upgrade operations (HW/SW). It is possible to connect to AUX or CON, using Terminal Server (convert ip:port TCP x-> serial Y) or modem.
