Refer to the exhibit. What are the possible port roles for ports A, B, C, and D in this RSTP-enabled network?

• designated, alternate, root, root

• designated, root, alternate, root

• alternate, root, designated, root

• alternate, designated, root, root

Refer to the exhibit. Which destination MAC address is used when frames are sent from the workstation to the default gateway?

• MAC address of the virtual router

• MAC addresses of both the forwarding and standby routers

• MAC address of the standby router

• MAC address of the forwarding router

What is a secure configuration option for remote access to a network device?

• Configure SSH.

• Configure 802.1x.

• Configure an ACL and apply it to the VTY lines.

• Configure Telnet.

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 checks the local neighbor cache for the learned address and if the address is not cached, it it considered unique.

• 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.

• The host sends an ICMPv6 echo request message to the DHCPv6 or SLAAC-learned address and if no reply is returned, the address is considered unique.

• The host sends an ARP broadcast to the local link and if no hosts send a reply, the address is considered unique.

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.FE91.7799 Source IP: 10.1.1.10

• Source MAC: 00E0.FE91.7799 Source IP: 10.1.1.1

• Source MAC: 00E0.FE10.17A3 Source IP: 10.1.1.10

• Source MAC: 00E0.FE91.7799 Source IP: 192.168.1.1

After attaching four PCs to the switch ports, configuring the SSID and setting authentication properties for a small office network, a technician successfully tests the connectivity of all PCs that are connected to the switch and WLAN. A firewall is then configured on the device prior to connecting it to the Internet. What type of network device includes all of the described features?

• standalone wireless access point

• firewall appliance

• switch

• wireless router

Which wireless encryption method is the most secure?

• WEP

• WPA2 with TKIP

• WPA2 with AES

• WPA

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?

• The switches will load balance and utilize both EtherChannels to forward packets.

• Both port channels will shutdown.

• The resulting loop will create a broadcast storm.

• STP will block one of the redundant links.

What are three techniques for mitigating VLAN attacks? (Choose three.)

• Enable BPDU guard.

• Set the native VLAN to an unused VLAN

• Use private VLANs.

• Disable DTP

• Enable trunking manually

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?

• These VLANs cannot be deleted unless the switch is in VTP client mode.

• These VLANs can only be removed from the switch by using the no vlan 10 and no vlan 100 commands.

• These VLANs are default VLANs that cannot be 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.
