A network administrator is configuring a router as a DHCPv6 server. The administrator issues a show ipv6 dhcp pool command to verify the configuration. Which statement explains the reason that the number of active clients is 0? 1. No clients have communicated with the DHCPv6 server yet. 2.

What is the purpose of setting the native VLAN separate from data VLANs? 1. The native VLAN is for carrying VLAN management traffic only. 2. The native VLAN is for routers and switches to exchange their management information, so it should be different from data VLANs. 3. The security of management frames that are carried in the native VLAN can be enhanced 4. A separate VLAN should be used to carry uncommon untagged frames to avoid bandwidth contention on data VLANs. - ANS 4. A separate VLAN should be used to carry uncommon untagged frames to avoid bandwidth contention on data VLANs. Which two statements are characteristics of routed ports on a multilayer switch? (Choose two.) 1. In a switched network, they are mostly configured between switches at the core and distribution layers. 2.

Perform the tasks in the activity instructions and then answer the question. What is the problem preventing PC0 and PC1 from communicating with PC2 and PC3? 1. The serial interfaces of the routers are in different subnets. 2. The gigabit interfaces are passive. 3. The routers are using different OSPF process IDs. 4. No router ID has been configured on the routers. - ANS 1. The serial interfaces of the routers are in different subnets. Put these in order. Each router uses the database to construct a complete map of the topology and computes the best Each router is responsible for "saying hello" to its neighbors on directly connected networks. Each router builds a Link-State Packet (LSP) containing the state of each directly connected link Each router learns about its own directly connected networks. Each router floods the LSP to all neighbors, who then store all LSPs received in a database - ANS 5 2 3 1 4 When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default? 1. management VLAN ID 2. native VLAN ID 3. unused VLAN ID 4. data VLAN ID - ANS 2. native VLAN ID Refer to the exhibit. R1 was configured with the static route command ip route 209.165.200.224 255.255.255.224 S0/0/0 and consequently users on network 172.16.0.0/16 are unable to reach resources on the Internet. How should this static route be changed to allow user traffic from the LAN to reach the Internet? 1. Add an administrative distance of 254. 2. Change the destination network and mask to 0.0.0.0 0.0.0.0 3. Add the next-hop neighbor address of 209.165.200.226. 4. Change the exit interface to S0/0/1. - ANS 2. Change the destination network and mask to 0.0.0.0 0.0.0.0 What best describes the operation of distance vector routing protocols? 1. They flood the entire network with routing updates. 2. They send their routing tables to directly connected neighbors. 3. They use hop count as their only metric. 4. They only send out updates when a new network is added. - ANS 2.

The company has been assigned a group of IPv4 addresses 209.165.200.224/29 from its ISP. What technology should the company implement in order to allow the workstations to access the services over the Internet? 1. static NAT 2. port address translation 3.
