1. A network administrator is selecting a switch that will operate at the network core. Which three features should the switch support for optimum network performance and reliability? (Choose three.)
10 Gigabit Ethernet
quality of service (QoS)
hot-swappable hardware
2. Refer to the exhibit. Beginning with HR servers and workstations, a network engineer is designing a new security structure for the network. Which set of policies adheres to the hierarchical network model design principles?
Configure port security options on S1. Use Layer 3 access control features on D1 and D2 to limit access to the HR servers to just the HR subnet.
3. Which layer of the OSI model does an access layer LAN switch use to make a forwarding decision?
Layer 2
4. What is the likely impact of moving a conventional company architecture to a completely converged network?
A shared infrastructure is created resulting in a single network to manage.
5. Configuring communication between devices on different VLANs requires the use of which layer of the OSI model?
Layer 3

Beginning with HR servers and workstations, a network engineer is designing a new security structure for the network. Which set of policies adheres to the hierarchical network model design principles?- Implement Layer 3 switching on S1 to reduce the packet processing load on D1 and D2. Install all security processing on S1 to reduce network traffic load.
- Configure port security options on S1. Use Layer 3 access control features on D1 and D2 to limit access to the HR servers to just the HR subnet.
- Move all HR assets out of the data center and connect them to S1. Use Layer 3 security functions on S1 to deny all traffic into and out of S1.
- Perform all port access and Layer 3 security functions on C1.
- At which heirarchical layer are switches normally not required to process all ports at wire speed?
- core layer
- distribution layer
- access layer
- entry layer
