1 Using the command copy tftp:backup.cfg startup-config, an administrator downloaded a saved config

from a TFTP server to a switch. Why does the administrator not detect any changes in the switch config

after the download completes?The command should have been copy startup-config tftp:backup.cfg.

A backup configuration from a TFTP server cannot be copied directly into the startup-config.

The command copy running-config startup-config should be used to save the changes on the switc

Downloading to the startup-config requires the switch to be reloaded in order for the configuration toeffect.

router interface fa0/0 and the switch interface fa0/1. The router and switch have been configured with thcommands that are displayed in the exhibit. The network administrator enters the show interfaces trun

The trunk is established, but no VLANs have been configured to use it.

The router is missing the dynamic trunking protocol statements necessary to form a trunk.Because the router does not support Dynamic Trunking Protocol, the trunk has not been established.

The router, the switch, or both must be configured with the dynamic desirable option for Dynamic Protocol to establish a trunk.

46 Which statement is accurate about fast-forward switching?

The switch stores the first 64 bytes of the frame before forwarding.After reading the destination address, the switch immediately forwards a frame.

The switch receives the complete frame and stores it in buffers before forwarding it.

The switch analyzes the frame for information about its destination. After confirming the integrity of

frame, the switch forwards it out the correct port.

48 Which statement is correct about STP architecture?

Spanning Tree Protocol will guarantee a loop free Layer 2 topology.

Spanning Tree Protocol guarantees the shortest path to destination networks.The switch with the highest priority will be assigned the lowest BID in the root election.

The first step in the spanning-tree election process is to determine the root port.

To select designated ports, the spanning-tree algorithm must determine the longest contiguous path frroot bridge.

49 How are data frames identified and sent to the correct VLAN when exiting an Ethernet trunk?Frames are forwarded to the correct VLAN based on the VLAN tag.

Frames are always forwarded to the native VLAN when exiting a trunk.

Frames are forwarded to the correct VLAN based on the source IP address.
