Perform the POST routine. 15 What will be the result of adding the command ip dhcp excluded-address 10.10.4.1 10.10.4.5 to the configuration of a local router that has been configured as a DHCP server? Traffic that is destined for 10.10.4.1 and 10.10.4.5 will be dropped by the router. The DHCP server will not issue the addresses ranging from 10.10.4.1 to 10.10.4.5. Traffic will not be routed from clients with addresses between 10.10.4.1 and 10.10.4.5.

  7. 7. Refer to the exhibit. A network administrator is implementing the stateless DHCPv6 operation for the company. Clients are configuring IPv6 addresses as expected. However, the clients are not getting the DNS server address and the domain name information configured in the DHCP pool. What could be the cause of the problem? The router is configured for SLAAC operation. The DNS server address is not on the same network as the clients are on. The GigabitEthernet interface is not activated. The clients cannot communicate with the DHCPv6 server, evidenced by the number of active clients being 0. 22 What impact does the use of the mdix auto configuration command have on an Ethernet interface on a switch? automatically detects interface speed automatically detects duplex settings automatically detects copper cable type automatically assigns the first detected MAC address to an interface 23 What are two advantages of EtherChannel? (Choose two.) Spanning Tree Protocol ensures redundancy by transitioning failed interfaces in an EtherChannel to a forwarding state. Load balancing occurs between links configured as different EtherChannels. Configuring the EtherChannel interface provides consistency in the configuration of the physical links. Spanning Tree Protocol views the physical links in an EtherChannel as one logical connection. EtherChannel uses upgraded physical links to provide increased bandwidth. 24 open in browser PRO version Are you a developer? Try out the HTML to PDF API pdfcrowd.com

What action should be taken by the network administrator? A response from the network administrator is not required because the TTL field will eventually stop the frames from flooding the network. Broadcast traffic should be investigated and eliminated from the network. Redundant links should be physically removed until the STP instance is repaired. Spanning tree should be disabled ?for that STP instance until the problem is located. 41 A network administrator has configured an EtherChannel between two switches that are connected via four trunk links. If the physical interface for one of the trunk links changes to a down state, what happens to the EtherChannel? The EtherChannel will remain functional.

An attacker on PC-A sends a frame with two 802.1Q tags on it, one for VLAN 10 and another for VLAN 20. What will happen to this frame? ALS1 will leave both tags on the frame and send it to ALS2, which will forward it to hosts on VLAN 10. ALS1 will remove both tags and forward the rest of the frame across the trunk link, where ALS2 will forward the frame to hosts on VLAN 10. ALS1 will remove the outer tag and send the rest of the frame across the trunk link, where ALS2 will forward the frame to hosts on VLAN 20.
