CCNA 3 Chapter 7 V4.0 Answers
1. Which two statements concerning network security are accurate? (Choose two.)
802.11i uses 3DES for encryption.
Open authentication uses no client or AP verification.
The 802.11i protocol is functionally identical to WPA.
802.11i incorporates a RADIUS server for enterprise authentication.
A wireless client first associates with an AP and then authenticates for network access.
2. Which installation method will allow connectivity for a new wireless network?
set up WEP on the access point only
set up open access on both the access point and each device connected to it
set up full encryption on the access point while leaving each device connected to the network open
set up full encryption on each device of the WLAN while leaving the access point settings open

1. What are the steps which must be completed in order to enable inter-VLAN routing using router-on-a-stick?
Configure the physical interfaces on the router and enable a routing protocol.
Create the VLANs on the router and define the port membership assignments on the switch.
Create the VLANs on the switch to include port membership assignment and enable a routing protocol on the router.
Create the VLANs on the switch to include port membership assignment and configure subinterfaces on the router matching the VLANs.
2.
Refer to the exhibit. R1 is routing between networks 192.168.10.0/28 and 192.168.30.0/28. PC1 can ping R1 interface F0/1, but cannot ping PC3. What is causing this failure?
PC1 and PC3 are not in the same VLAN.
The PC3 network address configuration is incorrect.
The S1 interface F0/11 should be assigned to VLAN30.
The F0/0 and F0/1 interfaces on R1 must be configured as trunks.

1. Which two criteria does a switch use to select the root bridge? (Choose two.)
bridge priority
switching speed
number of ports
base MAC address
switch location
memory size
2. Which two statements are true about the default operation of STP in a Layer 2 switched environment that has redundant connections between switches? (Choose two.)
The root switch is the switch with the highest speed ports.
Decisions on which port to block when two ports have equal cost depend on the port priority and identity.
All trunking ports are designated and not blocked.
Root switches have all ports set as root ports.
Non-root switches each have only one root port.

1. Which statement is true when VTP is configured on a switched network that incorporates VLANs?
VTP is only compatible with the 802.1Q standard.
VTP adds to the complexity of managing a switched network.
VTP allows a switch to be configured to belong to more than one VTP domain.
VTP dynamically communicates VLAN changes to all switches in the same VTP domain.
2.
Refer to the exhibit. What information can be learned from the output provided?
It verifies the configured VTP password.
It verifies the VTP domain is configured to use VTP version 2.
It verifies VTP advertisements are being exchanged.
It verifies the VTP domain name is V1.
