1. Question 1171 · 1334 in bank

   Which port state processes BPDUs, but does not forward packets or update the address database in Rapid PVST+?

   • Ablocking
   • Blearning
   • Clistening
   • Ddisabled

   Show answer

   Answer: A

   Explanation

   The answer is 100% A. First of all, please do not confuse.. RSTP is NOT the same as Rapid PVST+. Rapid PVST+ has 4 different states, Blocking, Learning, Forwarding, Disabled. But RSTP has 3 different states, Discarding, Learning, Forwarding. For Rapid PVST+, the exact answer described by the question is "Blocking" state. For RSTP, it is "Learning" state. Again, the question is regarding Rapid PVST+. So the answer is A.

2. Question 1172 · 1334 in bank

   A switch is forwarding a frame out of all interfaces except the interface that received the frame. What is the technical term for this process?

   • AARP
   • BCDP
   • Cflooding
   • Dmulticast

   Show answer

   Answer: C

3. Question 1173 · 1334 in bank

   

   Refer to the exhibit. When PC-A sends traffic to PC-B, which network component is in charge of receiving the packet from PC-A, verifying the IP addresses, and forwarding the packet to PC-B?

   • Arouter
   • BLayer 2 switch
   • Cload balancer
   • Dfirewall

   Show answer

   Answer: A

   Explanation

   A IS CORRECT. PC--A and PC-B are not in the same network. Switches send traffic in layer 2 and within the same VLA while routers route traffic to different subnet and at layer 3.

4. Question 1174 · 1334 in bank

   

   Refer to the exhibit. Rapid PVST+ mode is on the same VLAN on each switch. Which switch becomes the root bridge and why?

   • ASW4, because its priority is highest and its MAC address is lower
   • BSW1, because its priority is the lowest and its MAC address is higher
   • CSW2, because its MAC address is the highest
   • DSW3, because its priority is the highest

   Show answer

   Answer: A

   Explanation

   This diagram is cut off at the top, right? The given answer is wrong because a switch does not become the root bridge by having the highest MAC address. First criterion is the switch with the lowest priority will become the root bridge, but if all switches have the same priority then the switch with the lowest MAC will become the root bridge

5. Question 1175 · 1334 in bank

   Which EtherChannel mode must be configured when using LAG on a WLC?

   • Aon
   • Bpassive
   • Cactive
   • Dauto

   Show answer

   Answer: A

   Explanation

   Be aware that even though the LAG acts as a traditional EtherChannel, Cisco WLCs do not support any link aggregation negotiation protocol, like LACP or PaGP, at all. Therefore, you must configure the switch ports as an unconditional or always-on EtherChannel.

7. Question 1177 · 1334 in bank

   Which switch concept is used to create separate broadcast domains?

   • ASTP
   • BVTP
   • CVLAN
   • DCSMA/CD

8. Question 1178 · 1334 in bank

   How must a switch interface be configured when an AP is in FlexConnect mode?

   • Aaccess port
   • BEtherChannel
   • CPoE port
   • Dtrunk port

   Show answer

   Answer: D

   Explanation

   Trunk. Since it puts the traffict directly on the switch in flexconnect mode it and it supports multiple vlans it needs to put it on the proper vlan. Source - I'm a CWNP

9. Question 1179 · 1334 in bank

   Select 2

   What are two features of PortFast? (Choose two.)

   • AConvergence is fast after a link failure.
   • BSTP loops are mitigated for uplinks to other switches.
   • CPorts transition directly from the blocking state to the forwarding state.
   • DPorts operate normally without receiving BPDUs.
   • EPorts that connect to the backbone automatically detect indirect link failures.

   Show answer

   Answer: CD

   Explanation

   The official guide clearly specifies: After PortFast is configured and a port is activated, the port immediately transitions from the blocking state to the forwarding state. In a valid PortFast configuration, BPDUs should never be received because receipt of a BPDU indicates that another bridge or switch is connected to the port, potentially causing a spanning tree loop. A. Fast convergence after a link failure: This is a feature of RSTP (Rapid Spanning Tree Protocol). While PortFast reduces convergence time for a single switch port, it does not accelerate convergence for the entire network after a link failure.

10. Question 1180 · 1334 in bank

    What is the root port in STP?

    • AIt is the port with the highest priority toward the root bridge.
    • BIt is the port on the root switch that leads to the designated port on another switch.
    • CIt is the port that is elected only when the root bridge has precisely one port on a single LAN segment.
    • DIt is the port on a switch with the lowest cost to reach the root bridge.
