A company is planning to deploy high-availability cluster support for their servers in a collapsed
core data center design. Which issue should be a concern with this design?

Refer to the exhibit.

Which single design aspect should be configured on the ABRs to reduce the impact of WAN
upgrades for spoke routers on the core of the network?

Refer to the exhibit.

You must ensure that both core A and core B devices have only the minimum information required
for reaching the spoke routers yet maintain full reachability during network failures.
Which of the following design solutions accomplishes these requirements?

A Tier-3 Service Provider is evolving into a Tier-2 Service Provider due to the amount of

Enterprise business it is receiving. The network engineers are re-evaluating their IP/MPLS design
considerations in order to support duplicate/overlapping IP addressing from their Enterprise
customers within each Layer 3 VPN. Which of the following would need to be reviewed to ensure
stability in their network?

A Service Provider is designing a solution for a managed CE service to a number of local
customers using a single CE platform and wants to have logical separation on the CE platform
using Virtual Routing and Forwarding (VRF) based on IP address ranges or packet length. Which
is the most scalable solution to provide this type of VRF Selection process on the CE edge
device?

A Mobile Service Provider would like to design and deploy an Ethernet service which has similar
physical link failover/failback characteristics on the active/backup links as the APS/MSP SONET
properties. Which Layer 2 services should be considered to address this design feature?

You are tasked with implementing a 1000-phone remote access solution, where phone calls will
traverse a WAN edge router. Assuming all of the following features are supported in a hardwareassisted manner, which of the following will have the most negative impact on the delay of the
packet?

A company supports IPv4 and IPv6 addresses, and they need to be able to support flow-based
translations for multiple IPv6 devices to a single IPv4 address. Which address family translation
design solution should be recommended?

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

Refer to the exhibit.

You are designing a network using the Multiple Spanning Tree Protocol for loop avoidance. VLAN
trunking is not allowed due to security requirements. Which option describes how you can design
this Layer 2 network while using untagged interfaces between both switches?
