CCNA 3 Module 3 Exploration

. What statement about the 802.1q trunking protocol is true?
• 802.1q is Cisco proprietary.
• 802.1q frames are mapped to VLANs by MAC address.
• 802.1q does NOT require the FCS of the original frame to be recalculated.
• 802.1q will not perform operations on frames that are forwarded out access ports.

2. Which two statements describe the benefits of VLANs? (Choose two.)
• VLANs improve network performance by regulating flow control and window size.
• VLANs enable switches to route packets to remote networks via VLAN ID filtering.
• VLANs reduce network cost by reducing the number of physical ports required on switches.
• VLANs improve network security by isolating users that have access to sensitive data and applications.
• VLANs divide a network into smaller logical networks, resulting in lower susceptibility to broadcast storms.

3. What are two characteristics of VLAN1 in a default switch configuration? (Choose two.)
• VLAN1 should renamed.
• VLAN 1 is the management VLAN.
• All switch ports are members of VLAN1.
• Only switch port 0/1 is assigned to VLAN1.
• Links between switches must be members of VLAN1.

4. Refer to the exhibit. SW1 and SW2 are new switches being installed in the topology shown in the exhibit. Interface Fa0/1 on switch SW1 has been configured with trunk mode “on”. Which statement is true about forming a trunk link between the switches SW1 and SW2?
• Interface Fa0/2 on switch SW2 will negotiate to become a trunk link if it supports DTP.
• Interface Fa0/2 on switch SW2 can only become a trunk link if statically configured as a trunk.
• Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk link if the neighboring interface is configured in nonegotiate mode.
• Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk link automatically with no consideration of the configuration on the neighboring interface.

5. Refer to the exhibit. Computer 1 sends a frame to computer 4. On which links along the path between computer 1 and computer 4 will a VLAN ID tag be included with the frame?
• A
• A, B
• A, B, D, G
• A, D, F
• C, E
• C, E, F

Refer to the exhibit. What action does SW1 take on a frame sent from PC_A to PC_C if the MAC address table of SW1 is empty?
• SW1 drops the frame.
• SW1 floods the frame on all ports on SW1, except port Fa0/1.
• SW1 floods the frame on all ports on the switch, except Fa0/23 and Fa0/1.
• SW1 uses the CDP protocol to synchronize the MAC tables on both switches and then forwards the frame to all ports on SW2.
