Exam 200-301 topic 1 question 31 discussion

Access: Provides a connection point (access) for end-user devices. Does not forward frames between two other access switches under normal circumstances. Distribution: Provides an aggregation point for access switches, providing connectivity to the rest of the devices in the LAN, forwarding frames between switches, but not connecting directly to end-user devices. The distribution layer is where redistribution of routing protocols should be performed. It should never be performed at the core or access layer. Core: Aggregates distribution switches in very large campus LANs, providing very high forwarding rates for the larger volume of traffic due to the size of the network. Only switching between campus (distribution) switches should be performed at the core layer. Nothing should be done to slow down forwarding of traffic, such as using ACLs, supporting clients, or routing between VLANs Core layer switches are commonly set up in a star topology. This is because core layer switches connect multiple campuses via distribution layer switches

A correct because distribution layer has multilayer switches (L2 and L3 technologies) B correct oore provides reliability C incorrect because it must be core layer, not access D incorrect because it must be access layer, not core E incorrect because core & distribution only perform same functions in 2-tier model (since they are aggregated)

three-tire network topology it is relable. scalable . high performans 1. Core level 2. Distribution level 3. Acses level

what else could it be

A. The distribution layer runs Layer 2 and Layer 3 technologies B. The network core is designed to maintain continuous connectivity when devices fail are correct answers

A and B

The correct answers are A and B.

AB correct.

I was confused with this one because I don't normally use L3 switches at the distribution layer. However, what layer 3 function would run on the distribution layer. The routing usually happens that the core layer.

AB is the answer

A,B Is correct

AB IS THE BEST CHOICE

Is that mean even the core are down but the connectivity are still flowing for statement B?

A&B are ok. Core: Aggregates distribution switches in very large campus LANs, providing very high forwarding rates for the larger volume of traffic due to the size of the network. Only switching between campus (distribution) switches should be performed at the core layer. Nothing should be done to slow down forwarding of traffic, such as using ACLs, supporting clients, or routing between VLANs Core layer switches are commonly set up in a star topology. This is because core layer switches connect multiple campuses via distribution layer switches

The Distribution Layer (1.1.2.3) The distribution layer aggregates the data received from the access layer switches before it is transmitted to the core layer for routing to its final destination. In Figure 1-6, the distribution layer is the boundary between the Layer 2 domains and the Layer 3 routed network. The core should be highly available and redundant. The core aggregates the traffic from all the distribution layer devices, so it must be capable of forwarding large amounts of data quickly.
