CCNP SWITCH Exam Back to Exams Page 1. Which of the following are not capabilities of the access layer in a hierarchical network design? Low cost per switch port Security and policy-based connectivity functions High Layer 3 routing throughput High port densityQuestion 1 of 50 2. Which of the following is a characteristic of a core layer in a hierarchical network design? Aggregation of multiple access layer switches No costly or unnecessary packet manipulations (access lists, packet filtering) QoS features High port densityQuestion 2 of 50 3. When is a switch block considered to be too large? When the routers at the distribution layer become traffic bottlenecks When the broadcast or multicast traffic slows the switches in the switch block When you have more than 100 users connected to a single switch block When you start having more than 1G of traffic on the uplinks of the switches in the switch blockQuestion 3 of 50 4. What are some of the best practices with regards to the redundant hierarchical network design? Design each layer with pairs of switches Extend VLANs beyond distribution switches Connect each switch to the next higher layer with two links for redundancy Connect each pair of distribution switches with a link, but do not connect the access layer switches to each otherQuestion 4 of 50 5. What are the drawbacks of this hierarchical network design? The PCs should have been connected to the core switches to avoid loosing the network connectivity If the uplink of the access switches fails, the users connected to the that access switch will lose their connectivity to the network If the distribution switch fails, then the access switches will lose their connectivity to the network There are too many PCs connected to the access switchesQuestion 5 of 50 6. What is the drawback of this hierarchical network design? For increased redundancy, you always need four switches in the core There are no drawbacks with this design In case of a distribution uplink failure, the distribution switch will not be able to provide network connectivity to the access switches There is no uplink redundancy at access switches levelQuestion 6 of 50 7. What information is used by a switch to forward a frame? Destination MAC address Source MAC address Source IP address Destination IP addressQuestion 7 of 50 8. What does a switch do if the destination MAC address of the frame is not in the CAM? Keeps the frame in memory until the destination MAC address is in the CAM Drops the frame Floods the frame on all ports, except the port from which the frame was received Floods the frame on all portsQuestion 8 of 50 9. Which types of MAC addresses are not multicast? ffff.ffff.ffff 01xx.xxxx.xxxx 3333.xxxx.xxxx 0501.xxxx.xxxxQuestion 9 of 50 10. What kind of Multilayer Switching is Cisco Express Forwarding? Route Caching Topology based Demand based switching Flow based switchingQuestion 10 of 50 11. Which of the following is not contained in the TCAM of a switch? Security ACLs QoS ACLs MAC addresses IP addressesQuestion 11 of 50 12. What are the three actions that a switch must perform once a frame is taken from the ingress queue? Find the egress port by analyzing the L2 forwarding table Verify if the frame can be forwarded by analyzing the Security ACLs Update the MAC address table with the source MAC address of the frame Classify the frame according to the quality of service parameters by analyzing the QoS ACLsQuestion 12 of 50 13. What is the purpose of the Forwarding Information Base(FIB)? It temporarily stores new MAC addresses before they are added to the CAM table Contains each next-hop router’s Layer 2 MAC address and the egress switch port (and VLAN ID) It is consulted using the destination IP address as an index It contains the MPLS labelsQuestion 13 of 50 14.
