   SIMULATION - Guidelines - This is a lab item in which tasks will be performed on virtual devices • Refer to the Tasks tab to view the tasks for this lab item. • Refer to the Topology tab to access the device console(s) and perform the tasks • Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window • All necessary preconfigurations have been applied • Do not change the enable password or hostname for any device • Save your configurations to NVRAM before moving to the next item • Click Next at the bottom of the screen to submit this lab and move to the next question • When Next is clicked the lab closes and cannot be reopened Topology -

   

   Tasks - All physical cabling is in place. A company plans to deploy 16 new sites. The sites will utilize both IPv4 and IPv6 networks. 1. Subnet 172.16.0.0/16 to meet the subnet requirements and maximize the number of hosts • Using the second subnet - Assign the first usable IP address to e0/0 on Sw101 - Assign the last usable IP address to e0/0 on Sw102 2. Subnet 2001:DB8::/50 to meet the subnet requirements and maximize the number of hosts • Using the second subnet - Assign an IPv6 GUA using a unique 64-Bit interface identifier on e0/0 on Sw101 - Assign an IPv6 GUA using a unique 64-Bit interface identifier on e0/0 on Sw102

   Explanation

   trying to give an aswer, correct me if I am wrong 16 sites=2^4 /16 --> n°16 /20 172.16.0.0 - 172.16.15.255 172.16.16.0 - 172.16.31.255 and so on /50 --> n°16 /54 2001:0db8:0000:0000:0000:0000:0000:0000 - 2001:0db8:0000:03ff:ffff:ffff:ffff:ffff 2001:0db8:0000:0400:0000:0000:0000:0000 - 2001:0db8:0000:03ff:ffff:ffff:ffff:ffff and so on (every field separated by colons represent 16 bit, (every hexadecimal digits is 4 bit) IPv6 Global unicast address subnet minimum prefix lenght is 64 thus the two address are 2001:db8:0:400::1/64 2001:db8:0:400::2/64 sw101 int e0/0 ip address 172.16.16.1 255.255.240.0 ipv6 address 2001:db80:400::1/64 sw102 int e0/0 ip address 172.16.31.254 255.255.240.0 ipv6 address 2011:db8:0:400::2/64

   Which interface is used to send traffic to the destination network?

   

   • AG0/21
   • BG0/4
   • CG0/5
   • DG0/16

   Show answer

   Answer: D

   Explanation

   The answer is D. If we have the same prefix, next criteria is the Administrative Distance. In this case, AD 90 will be selected. If we have the same AD, next criteria is the metrics. In this case, route with lowest metrics, will be selected.

   Answer: B

   Explanation

   txload 1/255: This indicates how “busy” the interface is when it comes to transmitting frames. This is calculated every 5 minutes. rxload 1/255: The same as above but for receiving frames.

   What is the collapsed layer in collapsed core architectures?

   • ACore and distribution
   • Baccess and WAN
   • Cdistribution and access
   • Dcore and WAN

   Show answer

   Answer: A

   Explanation

   Answer A Correct https://www.juniper.net/documentation/en_US/release-independent/nce/topics/concept/nce-182-evpn-collapsed-core-evpn-multihoming-campus-overview.html#:~:text=A%20collapsed%20core%20architecture%20takes,layer%20on%20a%20single%20switch. A collapsed core architecture takes the normal three-tier hierarchical network and collapses it into a two-tier network. In a two-tier network, the function of the switches in the core layer and distribution layer are “collapsed” into a combined core and distribution layer on a single switch.

   Select 2

   What are two functions of DHCP servers? (Choose two.)

   • Aissue DHCPDISCOVER messages when added to the network
   • Brespond to client DHCPOFFER requests by Issuing an IP address
   • Csupport centralized IP management
   • Dassign dynamic IP configurations to hosts in a network
   • Eprevent users from assigning their own IP addresses to hosts

   Show answer

   Answer: CD

   Explanation

   You guys high? DHCPOFFER is a server message, not a client message. The DHCP server does *not* respond to DHCPOFFER messages, it *sends* them. The client must then send a DHCPREQUEST, to which the server will respond with a DHCPACK. B is completely incorrect. As for the other answers: A -> Incorrect; DHCPDISCOVER messages are sent by DHCP clients. E -> Incorrect; DHCP does not prevent static assignments on hosts. (Pro-tip: Don't trust ChatGPT for these questions; it's wrong as often as it is right).

10. Question 190 · 1334 in bank

    What is the operating mode and role of a backup port on a shared LAN segment in Rapid PVST+?

    • Alearning mode and provides the shortest path toward the root bridge handling traffic away from the LAN
    • Bblocking mode and provides an alternate path toward the designated bridge
    • Cforwarding mode and provides the lowest-cost path to the root bridge for each VLAN
    • Dlistening mode and provides an alternate path toward the root bridge

    Show answer

    Answer: B

    Explanation

    B is correct Backup ports do not forward user data frames, instead they remain in a blocking state, ensuring loop-free topology and allowing for rapid convergence in the event of link failures.
