B. Control plane policers are really needed only on externally facing devices

C. Control plane policers can cause the network management systems to create false alarms

D. Control plane policers are enforced in hardware to protect the software path, but they are hardware platform-dependent in terms of classification ability

You have been asked to design a high -density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

A. Implement a four-channel design on 2.4 GHz to increase the number of available channels.

B. Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual- band clients are used.

C. Choose a high minimum data rate to reduce the dory cycle.

D. Enable 802.11n channel bonding both 2.4 GHz and 5 GHz to increase the aggregated cell throughput.

E. Increase the number of SSIDs to load-balance the client traffic.

What is an implication of using route reflectors in an iBGP topology?

A. Route reflection limits the total number of iBGP routers.

B. Route reflection causes traffic to flow in a hub-and-spoke fashion.

C. The manipulation of BGP attributes is not supported on the other routers than the route reflectors.

D. Route reflectors can create routing loops when more than one router reflector is used in the same cluster.

E. Multipath information is difficult to propagate in a route reflector topology.

Which mechanism enables small, unmanaged switches to plug into ports of access switches without risking switch loops?

A. PortFast

B. UDLD

C. Root guard

D. BPDU guard

A large ISP is analysing which IGP meets these following requirements

Network must be resilient against unstable MTU in one side of newly released transmission pieces of equipment

Network must support MPLS traffic engineering solution for future use

Which IGP must be selected and why?

A. ISIS : in case MTU changes your TE tunnels keep the LSP stable

B. OSPF: adjacency remains up even if MTU changes

C. OSPF: in case MTU changes your TE tunnels keep the LSP stable

D. ISIS: adjacency remains up even if MTU changes

When designing a network .Which method can be used to control the exit point for traffic an autonomous system, at the layer 3 control plane?

A. Prepending AS path.

B. Tuning the multi-exit discriminator.

C. Setting the site of Origin extended community.

D. Tuning the metric of the under-tying IGP.

You must measure the amount of traffic that a mobile packet gateway produces when mobile phones access rather than the Internet. Which action do you take to allow this visibility?

A. Poll OID that is configured for internal servers with SNMP.

B. Collect information about traffic to the service prowler marked with IP precedence.

C. Collect traffic information that is related to internal server IP addresses with NetFlow.

D. Measure traffic characteristics of known internal servers with IP SLA.

You must make IGP redesign recommendations for a client that has old equipment, with low CPU power and memory, that they do not have budget replace. They are very concerned about CPU load on routers. They are using IS-IS as the IGP in a single l1 area and all routers are connected to each other with point-to-point links. Which method do you recommend to reduce or limit CPU overhead caused by IS-IS?

A. Use mesh groups to limit flooding of LSAs

B. Implement wide style metrics for IS-IS on all routers

C. Select a router to act as a pseudowire to limit topology synchronization

D. Divide the router into multiple areas and implement address summarization

Which two application requirements are mandatory for traffic to receive proper treatment when placed in the priority queue? (Choose two)

A. WRED drop treatment

B. Small transactions (HTTP ?like behavior)

C. Tolerance to packet loss

D. Intolerance to jitter

E. TCP based application

Your client is considering acquiring a new IPv6 address block so that all Ethernet interfaces on the network receive addresses based on their burned-in hardware addresses, with support for 600 VLANs. Which action do you recommend?

A. Acquire a new /60 IPv6 network and subnet it into /70 networks, one per VLAN

B. Acquire a new /58 IPv6 network and subnet it into /64 networks, one per VLAN

C. Acquire a new /60 Ipv6 network and subnet it into /68 networks, one per VLAN

D. Acquire a new/54 IPv6 network and subnet it into /64 networks , one per VLAN

In an OSPF network, users in a particular OSPF non-backbone area are complaining about show access speeds to a shared corporate resource in another OSPF area. Traceroutes show that the users are taking a suboptimal default route to the destinations. Which solution will improve access speed?

A. Make the area totally stubby so that the default can be followed along the best path

B. Create a virtual link between the areas so that traffic can shortcut directly between them

C. Leak specific summaries on the ABRs for the remote subnets in addition to the default

D. Implement policy routing to channel the traffic in the optimal direction
