Yes it can and the reason is because of redundancy provides for a backup route or network connection in case of a link failure. The core hardware is typically interconnected to all distribution network hardware and the objective is to ensure that the data traffic continues for the whole network even if a core networking device or link fails.

What is the advantage of using a layer 3 switch in the core of a campus network?
The speed at which it establish a network connection.
What is the advantage of using a layer 3 switches in the core of a campus network?
The advantage of using a layer 3 switch is the speed at which it can establish a network connection.
Can a layer 2 switch be used on the core of the campus network?
a high grade layer 2 switch can be used to access local resources but will not be suffice to access the internet you would need a layer3 switch to access remote resources
What networking equipment is usually found in the core of a campus Network?
High-end layer 3 switches or routers
Diifference between distribution layer switch core layer switch?
Core layer switch forms the heart of the network. it interconnects all the subnetworks formed by distribution switches. It also has special modules such as IDPS. It has very high switching capacity when compared with normal (Access ) Switches. Distribution switch forms the intermediate layer between access and core switch.
What would you recommend for the core switches?
Depending on the size of the network and actual traffic requirements technically a "core layer switch" can scale from a 2960 all the way up to and beyond a 6500.
What is the name for the part of the campus network that carries the bulk of the routed data traffic?
This central and/or core portion of a campus network that carries and/or routes the bulk of traffic typically is referred to as the "backbone."
What does a core switch do in a network?
It lets all nodes connected to the network get full available bandwidth on the network.
What is another name for the core layer of the network?
High-speed backbone
What are the primary layers of a hierarchical campus network?
Over time, the hierarchical approach to network design has proven the most effective. The three primary layers of a hierarchical campus follow: * Backbone or core- The backbone is the central thoroughfare for corporate traffic. All other parts of the network eventually feed into the backbone. You should design the core to switch packets as quickly as possible. This level should not include operations that might slow the switching of the packet: the distribution layer should handle any packet manipulation or filtering that needs to occur. * Distribution- The distribution layer provides policy-based connectivity and boundaries between the access layers and the core. For example, a building of 20 floors might have a distribution network that connects each of the floors with the backbone. It is at this layer that packets should be filtered or manipulated. Therefore, once packets are "prepped," the core simply needs to switch them quickly to the destination distribution location. * Access- The access layer provides user access to the network. It is at this point that users are permitted (or denied) access into the corporate network. Typically, each person sitting at a desk has a cable that runs back to a wiring closet and connects to a switch; hence, this level is where the user "accesses" the network. The distribution and core layers of the network provide vital services by aggregating groups of users and services. Therefore, if a distribution or core device dies, it can affect large communities of users. For this reason, reducing the chance of failure in these layers reduces and possibly prevents unnecessary and unplanned outages. Redundant network paths, redundant hardware, and fault-tolerant-related network protocols (such as Hot Standby Router Protocol) all aid in the ability of a network to recover quickly (and, you hope, transparently to the users) after a failure.

Link aggregation should be implemented at which layer of the hierarchical network?
access, distibution and core
Which stage in the process of gathering network symptoms involves identifying if the problem is at the core distribution or access layer of the network?
You narrow the scope
