Exam N10-008 topic 1 question 641 discussion

C. Layer 2 switch " Access – controls user and workgroup access to the resources on the network. This layer usually incorporates Layer 2 switches and access points that provide connectivity between workstations and servers. You can manage access control and policy, create separate collision domains, and implement port security at this layer. " https://study-ccna.com/cisco-three-layer-hierarchical-model/

Access Ethernet switches are usually fixed port configurations ranging from 12 to 48 ports and are layer two/VLAN based in the most common architecture.

I initially though B but upon further research I changed my mind to C. Exam Cram Network Plus book (great book btw) The access/edge layer is the place where switches connect to and ensure data is delivered to edge/end devices.

For sure, did research.

Comptia Says C

Comptia Says C

From CompTIA's Student Guide: Access or edge layer - connected to workgroup switches. Switches deployed to serve the access layer might also be referred to as LAN switches or data switches. Distribution or aggregation layer - The layer 3 capable switches used to implement the distribution/aggregation layer have different capabilities to the layer 2 only workgroup switches used in the access tier. Looks like the answer is: "C"

I'm literally pulling out a definition from the Cengage Net+ Book: "The access layer, or edge layer, consists of workgroup switches connected directly to hosts such as servers, printers, and workstations. Ideally, hosts connect only to access switches and never to switches at the other layers, although this is not always the case in the real world. Access switches typically organize traffic according to OSI layer 2 technologies." Emphasis on "according to OSI layer 2 technologies" which multilayer switches are not.

The best answer suited for use at the access layer in a three-tier architecture system is C. Layer 2 switch. In a three-tier system, the tiers are typically the core, distribution, and access layers. The access layer connects directly to end user devices to provide network access. An ideal access layer device is a Layer 2 switch. A router (A) operates at Layer 3 and is more commonly found at the core or distribution layers. A multilayer switch (B) also operates at Layers 2/3 and is overkill for basic access layer functions. An access point (D) could provide wireless access connectivity, but a Layer 2 switch is most appropriate for wired access connections.

layer 2 switches are using in Access layer

Going to have to go against the grain on this one. IMO "best suited for" has a different meaning than CompTIA's typical "best" definition. Purely the best would certainly be B, but you're not going to use a multilayer switch at the access layer in the real world. "Best suited for" to me means what you would expect to find at the access layer, which by definition of the three-tiered architecture is a switch. The Distribution/Aggregation layer is where routing functions become relevant. https://www.omnisecu.com/cisco-certified-network-associate-ccna/three-tier-hierarchical-network-model.php

Answer is B.

It's B) because in question its says " "best" suited for use" so im asuming the cost is not an issue

this need to be a better question, is both B and C just that B cost more and has more features but C also works, just cheaper and less features, over all stick with B unless proven other wise

C. Layer 2 switch Explanation: In a three-tier architecture system, which typically consists of an access layer, distribution layer, and core layer, the access layer is responsible for connecting end devices, such as computers and printers, to the network. The primary considerations for devices at the access layer include providing connectivity, access control, and segmentation.

B. Multilayer Switch (BEST answer) Rationale: Layer 2 switches can (and do) reside at the access layer, BUT multilayer switches are used at the access layer to efficiently manage local traffic within a network segment while also allowing for inter-VLAN routing.
