256 - 192 = 64. 64 + 64 = 128. 128 + 64 = 192. The subnet is 128, the broadcast address is 191, and the valid host range is the numbers in between, or 129-190.
2. What protocols are used to configure trunking on a switch?
VTP is not right because it has nothing to do with trunking except that it sends VLAN information across a trunk link. 802.1Q and ISL are used to configure trunking on a port.
3. What does a VLAN do?
Options
A. Acts as the fastest port to all servers.
B. Provides multiple collision domains on one switch port.
C. Breaks up broadcast domains in a layer 2 switch internetwork.
D. Provides multiple broadcast domains within a single collision domain.
Correct Answer: Breaks up broadcast domains in a layer 2 switch internetwork.
Explanation:
VLANs break up broadcast domains at layer 2.
4. You have 10 users plugged into a hub running 10Mbps half-duplex. There is a server connected to the switch running 10Mbps half-duplex as well. How much bandwidth does each host have to the server?
Correct Answer: Stops an interface from sending periodic dynamic updates but not from receiving updates.
Explanation:
The
passive command, short for passive-interface, stops regular updates from being sent out an interface. However, the interface can still receive updates.
7. Which protocol does DHCP use at the Transport layer?
