Example Questions

Which of the following is true regarding the effect of EIGRP queries on the network design? Acme Costume Company is connecting its manufacturing facilities to its stores with a small point-to-multipoint Frame Relay IP WAN. Little growth is expected in the network infrastructure. Up to this point the company has been using a dial-on-demand network. Dropping WAN costs, however, have led them to consider using a high-speed WAN solution to improve access. Which two routing protocols could you deploy to support the new larger network while keeping costs down? (Choose two.) Which two of these are characteristics of multicast routing? (Choose two.) For acceptable voice calls, the packet error rate should be no higher than what value? You are the Cisco Network Designer in Cisco.com. Which layer NAS operating mode is ACL filtering and bandwidth throttling only provided during posture assessment? At a certain customer's site, a NAS is both physically and logically in the traffic path. The NAS identifies clients solely based on their MAC addresses. In which access mode has this NAS been configured to operate? (alma.131) Which option describes why duplicate IP addresses reside on the same network in Cisco network design? Which two protocol characteristics should be most considered when designing a single unified fabric for the Data Center? (Choose two.) ACME corporation owns a single MDS. Which two SAN tools can be used to optimize the use and cost of the switching hardware? (Choose two.) What two choices can you make when redundancy is required from a branch office to a regional office? (Choose two.) Which design topology incurs a performance penalty since there are two encryption-decryption cycles between any two remote sites? Which of the following two statements about Cisco NSF and SSO are the most relevant to the network designer? (Choose two) What are two characteristics of Server Load Balancing router mode? (Choose two.) When designing the routing for an Enterprise Campus network it is important to keep which of the following route filtering aspects in mind? Which statement about IDS/IPS design is correct? What is the recommended practice regarding UDLD when implementing it in all fiber-optic LAN ports? (alma.24) As an experienced technician, you are responsible for infrastructure design and global configuration changes. You are asked to deploy a Voice over Wireless LAN for your company. If the cells have the same channel, the separation between them should be: (alma.65) Which unique characteristics of the Data Center Aggregation layer must be considered by an Enterprise Campus designer? Which two are characteristics of RSVP? (Choose two.) What is the recommended practice when considering VPN termination and firewall placement? (alma.96) Users of a site-to-site VPN are reporting performance problems. The VPN connection employs IPSec and GRE and traverses several Ethernet segments. The VPN packets are being fragmented as they traverse the links. What would be two methods to overcome this problem? (Choose two.) Which of the following two are effective and simple means of employing route summarization within the Enterprise Campus network? (Choose two) Which two of these correctly describe asymmetric routing and firewalls? (Choose two.) Which two of these are characteristics of MPLS VPNs? (Choose two) Which option does the FabricPath technology use to create loop-free Layer 2 networks? One of your customers wishes to use the NAS to perform DHCP functions and does not currently have a Layer 3 gateway in its production network. Which gateway mode is appropriate for this customer? (alma.110) Which of the following two statements about Cisco NSF and SSO are the most relevant to the network designer? (Choose two.) When designing the WAN module within the enterprise edge, which document is used to specify the connectivity and performance agreements with the service provider? Which statement about Fibre Channel communications is correct? Sun Stable is a global insurance company with headquarters located in Houston, Texas. The campus there is made up of a number of office buildings located within the same vicinity. In 2003, a new building, Building 331B was added. The additional building houses approximately 1000 employees. Rather than deploy a private branch exchange (PBX) in the new building, Sun Stable has decided to implement an IP telephony solution. External calls will be carried across a MAN link to another building, where a gateway connects into the worldwide PBX network of Sun Stable. Voice mail and unified messaging components are required and all IP phones and workstations should be on separate VLANs and IP subnets. Which IP telephony deployment best suits their need? What is the purpose of IGMP in a multicast implementation? For acceptable voice calls, the packet error rate should be less than___% Which two of these are correct regarding the recommended practice for distribution layer design? (Choose two.) Which of these terms refers to call issues that cause variations in timing or time of arrival? Which of the following is a result when designing multiple EIGRP autonomous systems within the Enterprise Campus network? Which option is a recommended firewall topology? (diane.108) Which of these Layer 2 access designs does not support VLAN extensions? (Choose one) Which QoS requirement applies to streaming video traffic? Which two of these are characteristics of Metro Ethernet? (Choose two.) Which three best practices should be implemented at the campus backbone submodule to support the server farm module? (Choose three.) Which of these recommended designs provides the highest availability? Which statement about data center access layer design modes is correct? You are the Cisco Network Designer. Which is not major scaling, sizing, and performance consideration for an IPsec design? (alma.44) Which three Layer 2 access designs have all of their uplinks in an active state? (Choose three.) Which two modes does LACP support? (Choose two.) Which of the following features might be used by the Enterprise Campus network designer as a means of route filtering? Which three components comprise the AVVID framework? (Choose three.) Which three statements about zoning are correct? (Choose three.) Which statement about IPS and IDS solutions is true? Which roaming option will keep them on the same IP subnet when client traffic is being bridged through LAN interfaces on two WLCs?
