A company is deploying a wireless network in the distribution facility in a Boston suburb. The warehouse is quite large and it requires multiple access points to be used. Because some of the company devices still operate at 2.4GHz, the network administrator decides to deploy the 802.11g standard. Which channel assignments on the multiple access points will make sure that the wireless channels are not overlapping?

An administrator is trying to remove configurations from a switch. After using the command erase startup-config and reloading the switch, the administrator finds that VLANs 10 and 100 still exist on the switch. Why were these VLANs not removed?
Because these VLANs are stored in a file that is called vlan.dat that is located in flash memory, this file must be manually deleted.

Which method of IPv6 prefix assignment relies on the prefix contained in RA messages?
SLAAC
Refer to the exhibit. A network administrator has connected two switches together using EtherChannel technology. If STP is running, what will be the end result?
STP will block one of the redundant links.
Which two types of spanning tree protocols can cause suboptimal traffic flows because they assume only one spanning-tree instance for the entire bridged network? (Choose two.)
STP, RSTP
Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?
SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.
Refer to the exhibit. Host A has sent a packet to host B. What will be the source MAC and IP addresses on the packet when it arrives at host B?
Source MAC: 00E0.FE91.7799Source IP: 10.1.1.10
Refer to the exhibit. If the IP addresses of the default gateway router and the DNS server are correct, what is the configuration problem?
The IP address of the default gateway router is not contained in the excluded address list.
Which statement describes a result after multiple Cisco LAN switches are interconnected?
The broadcast
After a host has generated an IPv6 address by using the DHCPv6 or SLAAC process, how does the host verify that the address is unique and therefore usable?
The host sends an ICMPv6 neighbor solicitation message to the DHCP or SLAAC-learned address and if no neighbor advertisement is returned, the address is considered unique.
Refer to the exhibit. Which trunk link will not forward any traffic after the root bridge election process is complete?
Trunk2
