EIGRP supports internal and external routes. Which router should be configured as EIGRP stub routers while deploying EIGRP on a network? VLAN Tagging, also known as Frame Tagging, is a method developed by Cisco to help identify packets travelling through trunk links. When an Ethernet frame traverses a trunk link, a special VLAN tag is added to the frame and sent across the trunk link .How does ERS use the VLAN tag?

When designing a converged network, which measures can be taken at the building access layer to help eliminate latency and ensure end-to-end quality of service can be maintained? (Choose three.) Which tunneling mechanism provides confidentiality and tunneling capabilities? The Schuyler and Livingston Iron Works has been working on getting its network security under control. It has set up VPN with IPSec links to its suppliers. It has installed network vulnerability scanners to proactively identify areas of weakness, and it monitors and responds to security events as they occur. It also employs extensive access control lists, stateful firewall implementations, and dedicated firewall appliances. The company has been growing very fast lately and wants to make sure it is up to date on security measures. Which two areas of security would you advise the company to strengthen? (Choose two.) Which item will be attacked by a DoS attack? Which two practices need to be implemented to increase SNMPv1 security? (Choose two.) In a single broadcast domain, connect three routers via a standard Ethernet switch. STP is the only Layer 2 protocol running on this link. EIGRP is the only Layer 3 protocol running on this link, which uses a standard configuration. Then, one of the three routers is manually shut down. How will the other two routers discover the loss of this neighbor? NetFlow provides valuable information about network users and applications, peak usage times, and traffic routing. Which function is of NetFlow? Fibre Channel, or FC, is a gigabit-speed network technology primarily used for storage networking. Fibre Channel is standardized in the T11 Technical Committee of the InterNational Committee for Information Technology Standards (INCITS), an American National Standards Institute (ANSI) Caccredited standards committee. Which two of these correctly describe Fibre Channel? (Choose two.) What is one of the reasons that custom QoS ACLs are recommended over automatic QoS when configuring ports on a Catalyst 6500 for use with IP phones? You are a network technician for the P4S Ltd. You are redistributing between EIGRP autonomous systems 100 and 200. Assume that there are no routing filters or aggregation applied anyplace in the network, which item is the result when a query originating in AS 100 reaches the router redistributing between the two autonomous systems? A service provider is offering four classes of service, with each class mapped to a separate queue. Some customers complain about receiving out-of-order packets, which cause application degradation. Which QoS policy activity most likely causes these out-of-order packets? Which two benefits does VoFR provide? (Choose two.) You are the Cisco Network Designer in P4S. Which two characteristics are most typical of a SAN? (Choose two.) Virtual Private LAN Services (VPLS) is a class of VPN that supports the connection of multiple sites in a single bridged domain over a managed IP/MPLS network. VPLS presents an Ethernet interface to customers, simplifying the LAN/WAN boundary for Service Providers and customers, and enabling rapid and flexible service provisioning, because the service bandwidth is not tied to the physical interface. Which of these statements best describes VPLS? In a network, all routers deploy FIFO queuing. The primary application running on the network is data backup by use of FTP. At certain times, users experience cyclical performance degradation. Which two items can mitigate this problem and help ensure bandwidth is used effectively in the network? (Choose two.) You are the Cisco Network Designer in P4S. Your company is using the G.711 codec with 802.11a access point radios. This can support a maximum of how many phones per access point? Which is the reason that H-VPLS is considered more scalable than flat VPLS? The IGP next-hop reachability for a BGP route is lost but a default route is available. Assuming that BGP connectivity is maintained, what will happen to the BGP route? Scalability is provided in the server farm module by which of the following design strategies?

When configuring the SPF exponential backoff timer, which one of the following items is among the primary issues to consider? Which description is true about RSVP reservations? A Fibre Channel fabric (or Fibre Channel switched fabric, FC-SW) is a switched fabric of Fibre Channel devices enabled by a Fibre Channel switch.

You are a network engineer for the P4S Ltd. You are measuring one-way delay between two campus networks connected through an MPLS network. One campus is in Chicago and the other is in Dallas. The company has one appliance at each campus with which to measure the delay. Which of the following is a must for the two appliances in order for the engineer to measure one-way delay with the best possible accuracy?

For the following options, which deployment can provide the least amount of downtime and also allow for dual active-active hubs? The P4S company is planning to deploy a new multicast application in its network to do real-time trading. This application will be performed simultaneously by thousands of traders located throughout the network, each a source of several IP multicast streams, to carry the "sell" and "buy" trading bids.
