8 . What are two benefits of the IEEE 802.11n standard over the IEEE 802.11G? (Choose two.)
requires less equipment
provides improved range
permits increased data rates
has a single-input and a single-output

Refer to the exhibit. A company has acquired a new office in a campus environment. Switches in the existing office and the new office are directly connected by a trunk link. The VLANs and IP addressing are setup as shown in the exhibit. The computers in each office are not able to ping each other. What will fix the problem?
Use an access link between S2 and S3.
Connect S2 and S3 to a common router.
Set the subnet mask in the new office to /24.
Configure the new office default gateway to 172.17.10.1
Change the port assignments in the new office to a different VLAN.
11 . What is a possible impact of setting too short an aging time in the MAC address table of a switch?
overly large address table
unnecessary flooding of packets
excessive timeouts of static addresses
impaired ability to dynamically learn new addresses
Refer to the exhibit. The network administrator has just added VLAN 50 to Switch1 and Switch2. Hosts A, B, C, and D are correctly configured with IP addresses in the subnet range for VLAN 50. Host A can communicate with host B, but cannot communicate with host C or host D. What is the cause of this problem?
There is a native VLAN mismatch.
The Fa0/11 interface of Switch1 is not configured as a trunk.
The link between Switch1 and Switch2 is up but not trunked.
VLAN 50 is not allowed on the trunk link between Switch1 and Switch2.
Refer to the exhibit. Users complain that they do not have connectivity to the web server that is connected to SW1. What should be done to remedy the problem?
Allow all VLANs on the trunk link.
Configure VLAN 100 as the native VLAN for SW1.
Configure the trunk port in trunk mode on SW1.
Attach the web server to a router and configure inter-VLAN routing.
14 . What VLANs are allowed across a trunk when the range of allowed VLANs is set to the default value?
only the management VLAN
all VLANs except the extended range VLANs
all VLANs except 1 and 1002-1005
Refer to the exhibit. A new host needs to be connected to VLAN 1. Which IP address should be assigned to this new host?
