Following this examination. the technician makes recommendations for adding new switches where needed and replacing existing equipment that hampers performance. The technician is given a budget and asked to proceed. data-link layer distribution layer network layer physical layer Bottom of Form 5 Top of Form A network technician is asked to examine an existing switched network.) forwarding rate traffic flow analysis expected future growth number of required core connections number of hubs that are needed in the access layer to increase performance Bottom of Form 6 Top of Form At which heirarchical layer are switches normally not required to process all ports at wire speed? core layer distribution layer access layer entry layer Bottom of Form 7 Top of Form Link aggregation should be implemented at which layer of the hierarchical network? core only distribution and core access and distribution 2 . Which two pieces of information would be helpful in determining necessary port density for new switches? (Choose two.

StackWise technology allows the switch capabilities and ports to be expanded by the addition of line cards. access. StackWise technology allows the switch to deliver power to end devices by using existing Ethernet cabling. Which explanation accurately describes StackWise technology? StackWise technology allows up to eight ports to be bound together to increase available bandwidth. A shared infrastructure is created resulting in a single network to manage. Bottom of Form 3 . There is less bandwidth competition between voice and video streams. distribution. StackWise technology allows up to nine switches to be interconnected via the use of a fully redundant backplane. The Ethernet VLAN structure is less complex. QoS issues are greatly reduced. Bottom of Form 9 Top of Form What is the likely impact of moving a conventional company architecture to a completely converged network? Local analog phone service can be completely outsourced to cost-effective providers. and core Bottom of Form 8 Top of Form A technician is attempting to explain Cisco StackWise technology to a client that is setting up three stackable switches.

Beginning with HR servers and workstations. Install all security processing on S1 to reduce network traffic load.10 Top of Form Refer to the exhibit. Use Layer 3 security functions on S1 to deny all traffic into and out of S1. Move all HR assets out of the data center and connect them to S1. 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. Perform all port access and Layer 3 security functions on C1. Configure port security options on S1. a network engineer is designing a new security structure for the network. Use Layer 3 access control features on D1 and D2 to limit access to the HR servers to just the HR subnet. Bottom of Form 11 Top of Form Which hierarchical design characteristic would be recommended at both the core and distribution layers to protect the network in the case of a route failure? PoE redundancy aggregation access lists Bottom of Form 4 .
