Questions # 31:

A network is designed to use OSPF to reach eBGP peers. For eBGP peers to stay stable in case of a link failure, what condition should be avoided?

Options:

Advertise IP addresses used on eBGP statements via a normal OSPF area

Use an ACL to block BGP in one direction

Disable BGP synchronization

Advertise IP addresses used on eBGP peer statements via eBGP

Expert Solution

Questions # 32:

Which load balancing option for IP-only traffic is the least efficient in terms of EtherChannel physical links utilization?

Options:

On a per source IP address basis

On a per destination MAC address basis

On a per destination IP address basis

On a per port number basis

Expert Solution

Questions # 33:

There is an MPLS-enabled link constantly flapping on an MPLS VPN network. Given that the network runs OSPF as the IGP protocol, which design mechanism will stabilize the network and avoid constant re-convergence?

Options:

IP Event Dampening

OSPF fast hellos

IP SLA

Partial SPF

Expert Solution

Questions # 34:

How can EIGRP topologies be designed to converge as fast as possible in the event of a point-to-point link failure?

Options:

Build neighbor adjacencies in a triangulated fashion

Build neighbor adjacencies in a squared fashion

Limit the query domain by use of distribute lists

Limit the query domain b use of summarization

Limit the query domain by use of default routes

Expert Solution

Questions # 35:

For a redesign requirement of the service provider network, summarization was implemented at multiple locations for each summary range. Now some customers of the service provider are complaining of higher latency and performance issues for a server hosted in the summarized area. Which design issues must be considered when creating the summarization?

Options:

Summarization adds CPU overhead on the routers sourcing the summarized advertisement.

Summarization prevents the visibility of the metric to the component subnets.

Summarization causes packet loss when RPF is enabled.

Summarization creates routing loops.

Expert Solution

Questions # 36:

Which statement about TAP and TUN devices, which are used in a Linux/KVM cloud deployment model, is true?

Options:

TUN is for handling IP packets, but TAP is for handling Ethernet frames

TUN is for handling Ethernet frames, but TAP is for handling IP packets

TUN is for tunneling IP packets, but TAP is for tapping IP packets

TUN is for tunneling Ethernet frames, but TAP is for tapping Ethernet frames

Expert Solution

Questions # 37:

What is an effect of using ingress filtering to prevent spoofed addresses on a network design?

Options:

It reduces the effect of DDoS attacks when associated with DSCP remaking to Scavenger

It protects the network infrastructure against spoofed DDoS attacks

It filters RFC 1918 addresses

It classifies bogon traffic and remarks it with DSCP bulk

Expert Solution

Questions # 38:

Which option lists the cloud service models?

Options:

Internet as a Service, Platform as a Service, and Storage as a Service.

Infrastructure as a Service, Platform as a Service, and Storage as a Service.

Infrastructure as a Service, Platform as a Service, and Software as a Service.

Internet as a Service, Product as a Service, and Storage as a Service.

Internet as a Service, Platform as a Service, and Software as a Service.

Questions # 39:

As part of network design, two geographically separated data centers must be interconnected using Ethernet-over-MPLS pseudowire. The link between the sites is stable, the topology has no apparent loops, and the root bridges for the respective VLANs are stable and unchanging. Which aspect must be the part of the design to mitigate the risk of connectivity issues between the data centers?

Options:

Enable Spanning Tree on one data center, and Rapid Reconfiguration of Spanning tree on the other

Ensure that the spanning tree diameter for one or more VLANs is not too large.

Enable UDLD on the link between the data centers.

Enable root guard on the link between the data centers.

Expert Solution

Questions # 40:

Refer to the exhibit.

Question # 40

You are designing a data center migration from one location to another, which requires all existing VLANs spanned to the new data center to maintain host IP addressing. Two temporary Gigabit Ethernet circuits are available to extend the VLANs at Layer 2 to the location as trunk links between core switches in each location. Which solution provides maximum fault isolation between the two data centers to ensure a Layer

Issue in one data center does not affect the other during the migration?

Options:

Perform BPDU filtering over the trunk links

Enable STP PortFast on host ports within each data center

Run the dual links as multichassis Etherchannel trunk between core switches within each location

Perform HSRP filtering over the trunk links to maintain active HSRP gateways within each data center for each VLAN
