   What is the path for traffic sent from one user workstation to another workstation on a separate switch in a three-tier architecture model?

   • Aaccess ג€" core ג€" access
   • Baccess ג€" distribution ג€" distribution ג€" access
   • Caccess ג€" core ג€" distribution ג€" access
   • Daccess ג€" distribution ג€" core ג€" distribution ג€" access

   Show answer

   Answer: D

   Explanation

   Sorry team - simply not enough information to make a valid decision. Options 'a' and 'c' are out - that's obvious. Both options 'b' and 'd' are valid. It depends upon the topology and the source/destination pair. Just because one has a three-tier architectural model doesn't mean you have to use it. It is possible that it only goes up to the aggregation / policy making layer (distribution). It is possible that it has to travel across the core. All I know for sure is that it isn't possible to know given the limited information!

   What is the difference between IPv6 unicast and anycast addressing?

   • AAn individual IPv6 unicast address is supported on a single interface on one node, but an IPv6 anycast address is assigned to a group of interfaces on multiple nodes.
   • BIPv6 anycast nodes must be explicitly configured to recognize the anycast address, but IPv6 unicast nodes require no special configuration.
   • CIPv6 unicast nodes must be explicitly configured to recognize the unicast address, but IPv6 anycast nodes require no special configuration.
   • DUnlike an IPv6 anycast address, an IPv6 unicast address is assigned to a group of interfaces on multiple nodes.

   Show answer

   Answer: A

   Explanation

   Both IPv6 anycast and unicast nodes require configuration, but the nature of the configuration differs between the two. Anycast nodes need explicit configuration to recognize the anycast address, while unicast nodes also require configuration, such as unique IPv6 addresses and network parameters.

   Refer to the exhibit. Between which zones do wireless users expect to experience intermittent connectivity?

   • Abetween zones 1 and 2
   • Bbetween zones 2 and 5
   • Cbetween zones 3 and 4
   • Dbetween zones 3 and 6

   Show answer

   Answer: C

   Explanation

   Correct. Only 3/4 over lap with channel 11 while the other presented options do not have overlapping channels. While in real life you might not experience intermittent connection you will suffer some degradation of performance as you essential have to take turns on the channel.

   Which WAN topology provides a combination of simplicity quality, and availability?

   • Apartial mesh
   • Bfull mesh
   • Cpoint-to-point
   • Dhub-and-spoke

   Show answer

   Answer: C

   Explanation

   D. Hub-and-spoke topology provides a combination of simplicity, quality, and availability. In a hub-and-spoke topology, all traffic flows through a central hub, which simplifies network design and management. The hub can be a router, switch, or any other network device that provides connectivity to the spokes. The spokes are the remote sites that are connected to the hub. The hub-and-spoke topology provides high-quality connections because each spoke has a dedicated connection to the hub. This dedicated connection ensures that there is no contention for bandwidth between different spokes, which can cause packet loss and delay. Moreover, the hub-and-spoke topology provides high availability because if one spoke fails, the other spokes can continue to communicate with each other through the hub. Additionally, if the hub fails, the spokes can still communicate with each other using backup links or alternate routes. Therefore, the hub-and-spoke topology is a popular choice for WAN deployments because it provides a good balance between simplicity, quality, and availability.

   DRAG DROP - Drag and drop the statements about wireless architectures from the left onto the architectures on the right. Select and Place:

   

   This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.

   Show the answer figure

   Answer: See figure below

   Explanation

   The correct answer is: Layer 2 Tunnel: Facilitates Layer 2 connectivity between the WLC's wired interface and the WLAN clients. Encapsulates LWAPP traffic between the access point and the WLC in Ethernet 0xBBBB. Layer 3 Tunnel: Requires IP addresses on the access point and the WLC. Uses UDP or UDP Lite for IPv6 deployments. The reason why "It forwards only IP EtherType frames" and "It supports LWAPP tunneling within Ethernet frames and UDP packets." are wrong because the CCNA exam is testing your knowledge of the different wireless architectures. These two points do not describe any specific wireless architecture. They simply describe the general features of a Layer 2 tunnel. The correct answer for the CCNA question describes the specific features of the two wireless architectures: Layer 2 Tunnel and Layer 3 Tunnel. This is the information that the CCNA exam is testing you on.

   DRAG DROP - Drag and drop the Wi-Fi terms from the left onto the descriptions on the right. Select and Place:

   

   This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.

   Show the answer figure

   Answer: See figure below

   Explanation

   the correct answers are: Extended service set = Wi-Fi option in which cells from different access points are linked together. Independant basic service set (Ad-Hoc) = Wi-Fi option that enables two or more clients to communicate directly without a central access point. Infrastructure mode = Wi-Fi option based around one or more access points. SSID = alphanumeric text string that identifies a wireless network. Distribution system = entire wireless cell of an access points and the linkage to the wired network.

7. Question 437 · 1334 in bank

   How are the switches in a spine-and-leaf topology interconnected?

   • AEach leaf switch is connected to one of the spine switches
   • BEach leaf switch is connected to each spine switch.
   • CEach leaf switch is connected to two spine switches, making a loop.
   • DEach leaf switch is connected to a central leaf switch, then uplinked to a core spine switch.

   Show answer

   Answer: B

   Explanation

   In spine-leaf two-tier architecture, every lower-tier switch (leaf layer) is connected to each of the top-tier switches (spine layer) in a full-mesh topology. The leaf layer consists of access switches that connect to devices such as servers. The spine layer is the backbone of the network and is responsible for interconnecting all leaf switches. Every leaf switch connects to every spine switch. Typically a Layer 3 network is established between leaves and spines, so all the links can be used simultaneously.

8. Question 438 · 1334 in bank

   What is the primary effect of the spanning-tree portfast command?

   • AIt immediately enables the port in the listening state.
   • BIt immediately puts the port into the forwarding state when the switch is reloaded.
   • CIt enables BPDU messages.
   • DIt minimizes spanning-tree convergence time.

   Show answer

   Answer: D

   Explanation

   I believe D is the right answer. When you enable PortFast on the switch, spanning tree places ports in the forwarding state immediately, instead of going through the listening, learning, and forwarding states. If answer B did not say " when the switch is reloaded" then it would have been the correct answer.

9. Question 439 · 1334 in bank

   What occurs when PortFast is enabled on an interface that is connected to another switch?

   • ARoot port choice and spanning-tree recalculation are accelerated when a switch link goes down.
   • BAfter spanning-tree converges, PortFast shuts down any port that receives BPDUs.
   • CVTP is allowed to propagate VLAN configuration information from switch to switch automatically.
   • DSpanning-tree fails to detect a switching loop increasing the likelihood of broadcast storms.

   Show answer

   Answer: D

   Explanation

   1 day later and a little wiser then yesterday I can tell that I was wrong. BPDU Guard needs to be enabled for that, which is not te case. So answer D is correct
