Questions # 31:

Which two reasons for implementing Cisco MPLS TE in a service provider MPLS backbone are valid? (Choose two.)

Options:

when Cisco MPLS TE is a prerequisite for implementing RSVP in the backbone

when Cisco MPLS TE is required to reroute traffic within Jess than 1 second in case of a link failure inside the backbone

when Cisco MPLS TE is required to create backup paths independently from the IGP

when Cisco MPLS TE can detect and react to neighbor failures faster than IGPs can

when Cisco MPLS TE is required to route different MPLS QoS service classes through different paths

Answer

C, E

Questions # 32:

Refer to the Exhibit.

Question # 32

In which three Layers should you use nonstop Forwarding to reduce service impact in case of failure? (Choose three)

Options:

Enterprise Edge

Enterprise Core

Service provider Edge

Dual-attached sever Layer

Enterprise Non-Routed Access Layer

Enterprise Non-Routed Distribution Layer.

Answer

A, B, C

Questions # 33:

What is a design application of control plane policing?

Options:

CPP protects the control plane from reconnaissance and or denial-of-service attacks

CPP protects the forwarding plane by rate –limiting excessive routing protocol traffic

CPP protects the forwarding plane by allowing legitimate traffic and dropping excessive traffic

CPP drop malformed packet that are sent to the CPU

Answer

Questions # 34:

Which two options are potential problems with route aggregation? (Choose two)

Options:

Maintaining host IP addresses during migrations

Route flapping

Suboptimal routing

Topology hiding

Asymmetric routing

Prefix hijacking

Answer

C, E

Questions # 35:

Refer to the exhibit.

Question # 35

You must review this single OSPF area, DMVPN network because the company has noticed a few area 0 convergence and stability issues. Also, traffic destined to the data center from one of the spokes as the next hop on the path. The company prefers that all traffic destined to the data center uses the least amount of hops. Which solution resolves these issues with the minimum amount of changes on the network?

Options:

Migrate from OSPF to static routes between the hub routers and the spoke routers and deploy IP SLA for route health checks

Migrate from OSPF to EIGRP between the hub routers and the spoke routers

Modify OSPF cost metrics on all backup links

Create areas between each hub and their spoke routers, to ensure that the hub routers become DRs

Answer

Questions # 36:

What is design considerations of policy-based routing?

Options:

It decreases failure detection time

It can create microloops during network reconvergence

It routes traffic destined to a set of users through different exit points

It uses RSVP to differentiate traffic flows, so queuing mechanisms can prioritize them

Answer

Questions # 37:

Refer to the exhibit.

Question # 37

On this MPLS-based network ring, links have failed between router A and router E. These failures formed microloops while the network converged, when A forwarded traffic to B but B forwards it back to A. Which technology is the simplest solution to avoid microloops without enabling a new protocol in the network?

Options:

TE Fast ReRoute

IP Fast ReRoute

Loop-Free Alternate

Remote Loop-Free Alternate

Answer

Questions # 38:

You are designing an IPv4 any source multicast redundancy solution. Which technology ensures the quickest RP convergence?

Options:

Bootstrap router

MSDP anycast RP

Auto-RP

Embedded RP

Answer

Questions # 39:

A large enterprise network has a partial mesh network with multiples redundant links. OSPF is used as IGP and it is implemented in a single-area. The network has slow convergence times and there is a high CPU utilization on the routers. Which solution can address these issues while ensuring that the network scales?

Options:

Break the routing domain into separate OSPF areas

Make it a hub-and-spoke topology

Replace OSPF with BGP

Reduce the number of links between routers in the network

Upgrade the routers with higher CPU and memory resources

Answer

Questions # 40:

An operations engineer asks for your help with a new switching deployment. The engineer confirms that STP is enabled on an edge switch, and a particular port is connected to another switch. The switch is not receiving configuration BPDUs, although it appears that everything is functioning correctly in the network. What is the design explanation?
