CCNA Exploration 3: LAN Switching and Wireless–Chapter 7 Exam (100% common)

01. Which two conditions have favored adoption of 802.11g over 802.11a? (Choose two.)

• 802.11a suffers from a shorter range than 802.11g.
• The 2.4 GHz frequency band is not as crowded as the 5 GHz band.
• 802.11a is more susceptible to RF interference from common commercial items.
• 802.11a uses a more expensive modulation technique than 802.11g.
• 802.11g is backward compatible with 802.11b, but 802.11a is not.

CCNA Exploration 3: LAN Switching and Wireless–Chapter 6 Exam (100% common)

01. 

Refer to the exhibit. Which three statements describe the network design shown in the exhibit? (Choose three.)

• This design will not scale easily.
• The router merges the VLANs into a single broadcast domain.
• This design uses more switch and router ports than are necessary.
• This design exceeds the maximum number of VLANs that can be attached to a switch.
• This design requires the use of the ISL or 802.1q protocol on the links between the switch and the router.
• If the physical interfaces between the switch and router are operational, the devices on the different VLANs can communicate through the router.

CCNA Exploration 3: LAN Switching and Wireless – Chapter 5 Exam (100% common)

01. 

Refer to the exhibit. All switches in the network have empty MAC tables. STP has been disabled on the switches in the network. How will a broadcast frame that is sent by host PC1 be handled on the network?

• Switch SW1 will block the broadcast and drop the frame.
• Switch SW1 will forward the broadcast out all switch ports, except the originating port. This will generate an endless loop in the network.
• Switch SW1 will forward the broadcast out all switch ports, except the originating port. All hosts in the network will reply with a unicast frame sent to host PC1.
• Switch SW1 will forward the traffic out all switch ports except the originating port as a unicast frame. All hosts in the network will reply with a unicast frame sent to switch SW1.

CCNA Exploration 3: LAN Switching and Wireless – Chapter 4 Exam

01. 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.

CCNA Exploration 3 LAN Switching and Wireless – Chapter 3 Exam (100% common)

01. 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.

CCNA Exploration 3 LAN Switching and Wireless – Chapter 2 Exam (100% common)

01. When a collision occurs in a network using CSMA/CD, how do hosts with data to transmit respond after the backoff period has expired?

• The hosts return to a listen-before-transmit mode.
• The hosts creating the collision have priority to send data.
• The hosts creating the collision retransmit the last 16 frames.
• The hosts extend their delay period to allow for rapid transmission.
