IP addresses Layer 1 statuses

Refer to the exhibit. A network administrator is configuring RT1 for inter-VLAN routing. The switch is configured correctly and is functional. Host1, Host2, and Host3 cannot communicate with each other. Based on the router configuration, what is causing the problem?

IP addresses on the subinterfaces are incorrectly matched to the VLANs.

Refer to the exhibit. What does R1 use as the MAC address of the destination when constructing the frame that will go from R1 to Server B?

If the destination MAC address that corresponds to the IPv4 address is not in the ARP cache, R1 sends an ARP request.

What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?​

It is a logical interface internal to the router.

Which statement describes a route that has been learned dynamically?

It is automatically updated and maintained by routing protocols.

Consider the following routing table entry for R1: D 10.1.1.0/24 [90/2170112] via 209.165.200.226, 00:00:05, Serial0/0/0 What is the significance of the Serial0/0/0?

It is the interface on R1 used to send data that is destined for 10.1.1.0/24.

What is a disadvantage of using multilayer switches for inter-VLAN routing?

Multilayer switches are more expensive than router-on-a-stick implementations.*

Refer to the exhibit. The switch does the routing for the hosts that connect to VLAN 5. If the PC accesses a web server from the Internet, at what point will a VLAN number be added to the frame?

No VLAN number is added to the frame in this design.

Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. What two conclusions can be drawn from the routing table? (Choose two.)

R1 does not know a route to any remote networks. The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A::12.

Refer to the exhibit. After attempting to enter the configuration that is shown in router RTA, an administrator receives an error and users on VLAN 20 report that they are unable to reach users on VLAN 30. What is causing the problem?

RTA is using the same subnet for VLAN 20 and VLAN 30

Which statement describes a disadvantage of using router subinterfaces for inter-VLAN routing?

Routed traffic must contend for bandwidth on a single router interface.

ill in the blank. When a router receives a packet, it examines the destination address of the packet and looks in the ____ table to determine the best path to use to forward the packet.

Routing

While configuring inter-VLAN routing on a multilayer switch, a/an " " is used as a virtual-routed VLAN interface.

SVI

Refer to the exhibit. What will the router do with a packet that has a destination IP address of 192.168.12.227? CCNA2 Chapter 4 v5.03 002

Refer to the exhibit. Which command can the administrator issue to change the VLAN10 status to up?​

Switch1(config)# vlan 10

Refer to the exhibit. Communication between the VLANs is not occurring. What could be the issue?

The Gi1/1 switch port is not in trunking mode.

What condition is required to enable Layer 3 switching?

The Layer 3 switch must have IP routing enabled.
