| To help select the optimal model of a replacement switch for a department, a network administrator performs extensive analysis of current and future usage. The administrator specifically examines how heavily the entire user community hits specific application servers, the additional load that expected future hires will place on the servers, and how much storage space future users will need. This is an example of what kind of analysis? | |
| data stores and data servers | |
| user communities | |
| network configuration management | |
| convergence impact | |
| What statement best describes a modular switch? | |
| a slim-line chassis | |
| allows interconnection of switches on redundant backplane | |
| defined physical characteristics | |
| flexible characteristics | |
| Which feature supports higher throughput in switched networks by combining multiple switch ports? | |
| network diameter | |
| load balancing across trunks | |
| convergence | |
| link aggregation | |
| Configuring communication between devices on different VLANs requires the use of which layer of the OSI model? | |
| Layer 1 | |
| Layer 3 | |
| Layer 4 | |
| Layer 5 | |
| Which two characteristics are associated with enterprise level switches? (Choose two.) | |
| low port density | |
| high forwarding rate | |
| high latency level | |
| support link aggregation | |
| predefined number of ports | |
| Which two features are supported at all three levels of the Cisco three-layer hierarchical model? (Choose two.) | |
| Power over Ethernet | |
| load balancing across redundant trunk links | |
| redundant components | |
| Quality of Service | |
| link aggregation | |
| What two factors are important to consider when designing a switched network for a small business of one to twenty employees? (Choose two.) | |
| Layer 3 functionality | |
| cost | |
| modular construction | |
| high port density | |
| PoE | |
| 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? | |
| switching | |
| redundancy | |
| aggregation | |
| access lists | |
| Which three statements describe the benefits of a hierarchical network model? (Choose three.) | |
| Scalability -- the design allows expansion which is easy to implement. | |
| Performance -- load balancing across trunk links. | |
| Manageability -- the network design enables the administrator to add switches by sharing configuration information between devices. | |
| Portability -- intermediary devices can be moved to alternative locations in the network when necessary to accommodate new users. | |
| Link aggregation -- creating a full mesh topology by adding hardware devices to improve bandwidth. | |
| Security -- ability to control which devices are allowed connectivity to the network. | |
| Refer to the exhibit. All switches except S3 are located in the MDF. The user community in HR has been reporting slow performance in all network applications since the HR1 application server was added to the data center. An extensive traffic analysis has shown that the Gi0/1 interface on S1 is frequently running at 100% bandwidth usage, and Gi0/2 is blocked by Spanning Tree Protocol. Company policy requires that the HR department be segregated from the general user community. There are no duplexing mismatches or cabling/hardware problems. All switches have available ports. What fix will alleviate the problem and meet company requirements? | |
| Manually enable the Gi0/2 port on S1 to split the traffic load. | |
| Divide the HR population between S1 and S3 to distribute the load between switches. | |
| Add a second HR application server and cluster them to reduce the load. | |
| Move the HR 1 Ethernet connection to S1 to reduce cross switch traffic. | |
| At which heirarchical layer are switches normally not required to process all ports at wire speed? | |
| core layer | |
| distribution layer | |
| access layer | |
| entry layer | |
| What is an important characteristic of a distribution level switch? | |
| PoE | |
| port speed | |
| QoS prioritization | |
| aggregating distribution layer switches | |
