CCNA 640-802-Hotspot(Topology)

CCNA640-802-hotspot

  • Question 1:
    If router has a packet destination address 192.168.1.255. What describes the operation of the network?
    Answer:
    R1 will drop this packet because it is not a valid ip address
    Explanation:
    The destination IP address 192.168.1.255 is broadcast address of the network 192.168.1.0 /24 on router R1.
    Network Address: 192.168.1.0 subnet mask: 255.255.255.0
    Network valid host range: 192.168.1.1 – 192.168.1.254
    Broadcast Address : 192.168.1.255
    Since router (R1) received a packet with destination IP address (192.168.1.255) which is broadcast address so it simply discards the packet as Forwarding broadcast packet can lead to severe storms of packets, and if uncontrolled could lead to network overload.
  • Question 2:
    Users on the 192.168.1.0 /24 network must access files located on the server 1. What route could be configured on router R1 for the file requests to reach the server ?
    Answer:
    ip route 0.0.0.0 0.0.0.0 s 0/0/0
    Explanation:
    To enable users on 192.168.1.0 network to access files on server1, we need to establish a default static route.
    Static route syntax:
    ip route prefix mask {ip-address interface-type interface-number [ip-address]} [distance] [name] [permanent track number] [tag tag]
    From the options provided for this question the correct default static route is
    ip route 0.0.0.0 0.0.0.0 S 0/0/0
    PS: As per best practices static route to server1 on R1 should have been
    ip route 209.165.200.0 255.255.255.0 209.165.100.200
    (or)
    ip route 209.165.200.0 255.255.255.0 s 0/0/0
  • Question 3:
    When a packet is sent from Host1 to Server1,in how many different frames will the packet be encapsulated as it is sent across the internetwork?
    Answer:
    3
    Explanation:
    First: Host1 encapsulates the packet into frames and forwards to the switch.
    Switch in turn forwards the same frame to router R1.
    Second: Router R1 receives the frame on one interface and it is encapsulates into new packet once it leaves the router R1 towards the direction of server1.
    Third: R2 receives this packet and it also encapsulates the frame into new packet when it is forwarded to server1 on different interface of R2.
    Therefore the packet is sent using three different frames to reach from Host1 to server1.
  • Question 4:
    What must be configured on the network in order for users on the internet to view web pages located on web server2?
    Answer:
    On router R1, configure a NAT to translate address on 209.165.100.0 to 192.168.1.0 network.
  • Question 5:
    The router address 192.168.1.250 is the default gateway for both web server2 and host 1. What is the correct subnet mask for this network?
    Answer:
    255.255.255.0
    Explanation:
    Given subnet mask for this network is 255.255.255.0 based on the exhibit.
    To find the correct subnet mask for this network based on number of devices shown in the exhibit that are already configured with IP address and by not wasting IP addresses scheme.
    The network 192.168.1.0 consists of only three devices as per the exhibits which are configured with IP address.
    R1(fa 0/0) : 192.168.1.250 ( default gateway as per the question)
    Host1: 192.168.1.106
    Web server 2: 192.168.1.10
    correct subnet mask that will cover all above IP address is 255.255.255.0

    Cisco Newbie - Start on the CCNA
     
    Want to start getting into routers etc so looking at doing some cisco stuff?
    Think you need to start on the CCNA? but dont really know where or know of any real books that can teach you this from scratch? Here is a guideline for the Cisco newbies to start on the CCNA.

    Q: Looking at doing some cisco stuff?

    A: Cisco’s Career Certifications & Paths information can be found here.
    Cisco also has a CCNA Prep Center — it might impress you, or it might scare you away — but worth a look to get an idea of what Cisco makes available.

    Only one comment on the prepCenter.
    When watching the flash, dont take their word when they say that linux is an operating system.

    One who says that linux is an OS, states that his knowledge of operating systems converging to zero (especially linux based).

    Q: Don’t really know where or know of any real books that can teach you this from scratch.

    A: The books you’ll hear the most about around here are:
    Sybex - Cisco Certified Network Associate Study Guide — by Todd Lammle. Should be on the 5th edition. Great for learning subnetting. Missing some info, but there are one or two new update chapters available for download.

    Cisco Press - The CCNA 640-802 books by Wendell Odom. Probably the CCNA Official Exam Certification Library.

    You can check out all the Cisco Press Books (and the link to the simulator) at the Cisco Press Web site.
    Hands-on practice is important…. but you can get by with the simulator for the CCNA.

    Q: Are the exams expensive?

    A: The CCNA 640-802 exam is $125.
    There is also the 2 exam option (INTRO and ICND). There should be link at the CCNP Prep Center that explains it. I think those are $100 each.

    That should be enough links to keep you busy for the rest of the night.
