  Explanation

  the "extendable" keyword should be added if the same Inside Local is mapped to different Inside Global Addresses (the IP address of an inside host as it appears to the outside network). An example of this case is when you have two connections to the Internet on two ISPs for redundancy. So you will need to map two Inside Global IP addresses into one inside local IP address.

  B. control plane forwarding
  C. data plane forwarding

  Topology

  

  Tasks

  The operations team started configuring network devices for a new site. Complete the configurations to achieve these goals:

  1. Configure Rapid PVST+ on SW20.

  2. The trunk between SW20 and SW30 is not operational. Troubleshoot the issue and ensure PC3 can ping PC1 (10.10.100.10) across the link.

  3. The LACP port channel between SW10 and SW20 is not operational. Troubleshoot the issue and ensure PC3 can ping PC2 (10.10.100.20) across the port channel.

  Note: No access is provided to SW10 or SW30. Resolve these issues by making changes only to SW20. Traffic on all trunks should be restricted to only active VLANs.

  Explanation

  Task 1: Configure Rapid PVST+ on SW20

  SW20(config)# spanning-tree mode rapid-pvst

  Task 2:

  1. Check Interface Configuration:

  Make sure that the trunk configuration is correctly set on interface e0/2 on SW20.

  SW20(config)# interface e0/2

  SW20(config-if)# switchport mode trunk SW20(config-if)# switchport trunk allowed vlan 500

  2. Ensure the Interface is

  Up:

  Check that the interface e0/2 is up:

  SW20# show interface e0/2

  3. Check and Clear Trunk Issues:

  Verify that VLAN 500 is allowed on the trunk and that there are no mismatches:

  SW20# show interfaces trunk

  SW20# show running-config interface e0/2

  4. If VLAN 500 is not listed, manually add it:

  SW20(config)# interface e0/2

  SW20(config-if)# switchport trunk allowed vlan add 500

  Task 3:

  Check LACP Configuration:

  Make sure that the interfaces e0/2 and e0/3 are correctly configured for LACP on SW20:

  SW20(config)# interface range e0/2 - 3 SW20(config-if-range)# channel-group 1 mode active

  Verify Port-Channel Configuration:

  Check the port-channel configuration and ensure that it's correctly set up:

  SW20# show etherchannel summary

  Restrict Trunk to Active VLANs: Ensure that only VLAN 500 is allowed on the port-channel trunk:

  SW20(config)# interface port-channel 1 SW20(config-if)# switchport trunk allowed vlan 500

  Verify and Ensure Connectivity: After making the configurations, verify that PC3 can ping

  PC2 (10.10.100.20) and PC1 (10.10.100.10):

  SW20# ping 10.10.100.20

  SW20# ping 10.10.100.10

• Question 1385:

  When using a Cisco Catalyst 9800 Series WLC, which tag/profile can be applied to APs to change the mode to FlexConnect in a specific location?

  A. policy tag
  B. site tag
  C. AP join profile
  D. flex profile
  B. site tag

• Question 1386:

  What is the role of the RP in PIM sparse mode?

  A. The RP responds to the PIM join messes with the source of requested multicast group
  B. The RP maintains default aging timeouts for all multicast streams requested by the receivers.
  C. The RP acts as a control-plane node and does not receive or forward multicast packets.
  D. The RP is the multicast that is the root of the PIM-SM shared multicast distribution tree.
  D. The RP is the multicast that is the root of the PIM-SM shared multicast distribution tree.

  ---

  Explanation

  Multicast Distribution Shared Tree - Unlike source trees that have their root at the source, shared trees use a single common root placed at some chosen point in the network. This shared root is called a rendezvous point (RP).

• Question 1389:

• Question 1390:

  Refer to the exhibit.

  

  A network engineer is enabling logging to a local buffer, to the terminal and to a syslog server for all debugging level logs filtered by facility code 7.

  Which command is needed to complete this configuration snippet?

  A. logging buffered debugging
  B. logging discriminator Disc1 severity includes 7
  C. logging buffered discriminator Dlsd debugging
  D. logging discriminator Disc1 severity includes 7 facility includes fac7
  D. logging discriminator Disc1 severity includes 7 facility includes fac7
