Q101. A company wants to use an external appliance between its data center and WAN to optimize email and HTTP communications. The traffic flow must pass this appliance in both directions. The appliance is connected with only one interface to a Cisco IOS router and has a single IP address. Which two adjustments can you make to the network design so that the appliance is added into the traffic path? (Choose two.) 

A. Configure static routes to route the traffic to the appliance. 

B. Adjust the dynamic routing to route the traffic to the appliance. 

C. Configure NAT to force the traffic to the appliance. 

D. Configure a route map at the data center-side interface to forward the traffic to the appliance IP address. 

E. Configure a route map at the appliance-facing interface to forward the traffic to the appliance IP address. 

F. Configure a route map at the WAN-side interface to forward the traffic to the appliance IP address. 

Answer: DF 


Q102. 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. Assigning unique Route Target ID's 

B. Assigning unique Route Distinguishers 

C. Assigning unique IP address space for the Enterprise NAT/Firewalls 

D. Assigning unique VRF ID's to each Layer 3 VPN 

Answer:


Q103. Refer to the exhibit. 

A service provider using IS-IS has designed this network with all core links at the Layer 2 control plane. How will they adjust the design to reduce the flooding of update packets? 

A. Change the area type of the links to be level-1-2 to allow level-1 updates. 

B. Change the network type of the links from broadcast to point-to-point. 

C. Use IS-IS mesh groups. 

D. Configure SPF timers to be more aggressive so that updates are more quickly cleared from the queue. 

Answer:


Q104. Refer to the exhibit. 

Assume that no multicast optimization is done on LAN switches A and B. Which feature can be used to optimize multicast traffic forwarding in this situation? 

A. Enable IGMP snooping querier on both switches. 

B. Configure a static MAC entry for the multicast server. 

C. Disable IGMP snooping on both switches. 

D. Disable the IGMP query election process. 

E. Enable PIM Snooping on both switches. 

Answer:


Q105. A data center provider has designed a network using these requirements: 

Two data center sites are connected to the public Internet. 

Both data centers are connected to different Internet providers. 

Both data centers are also directly connected with a private connection for the internal traffic, and public Internet traffic can also be routed at this direct connection. 

The data center provider has only one /19 public IP address block. 

Under normal conditions, Internet traffic should be routed directly to the data center where the services are located. When one Internet connection fails, the complete traffic for both data centers should be routed by using the remaining Internet connection. In which two ways can this routing be achieved? (Choose two.) 

A. The data center provider must have an additional public IP address block for this routing. 

B. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP weight and the /20 block from the remote data center is sent out with a higher BGP weight at both sites. 

C. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out without path prepending and the /20 block from the remote data center is sent out with path prepending at both sites. 

D. One /20 block is used for the first data center and the second /20 block is used for the second data center. Each /20 block is only sent out locally. The /19 block is sent out at both Internet connections for the backup case to reroute the traffic through the remaining Internet connection. 

E. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP local preference and the /20 block from the remote data center is sent out with a higher BGP local preference at both sites. 

F. BGP will always load-balance the traffic to both data center sites. 

Answer: CD 


Q106. You are the lead network designer for an enterprise company called ABC, and you are leading design discussions regarding IPv6 implementation into their existing network. A question is raised regarding older Layer 2 switches that exist in the network, and if any changes are required to these Layer 2 switches for successful IPv6 implementation. Which two responses should you give? (Choose two.) 

A. IPv6 is transparent on Layer 2 switches, so there is no need to make any changes to the Layer 2 switches. 

B. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ICMPv6 snooping at Layer 2 switches. 

C. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support DHCPv6 snooping at Layer 2 switches. 

D. If IPv6 multicast deployment is planned, then make sure that Layer 2 switches support MLD snooping at Layer 2 switches. 

E. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ND snooping at Layer 2 switches. 

Answer: AD 


Q107. You have been hired to redesign a network due to issues with congestion. How will a router function if the QoS mechanism of congestion avoidance is integrated into the existing network design? 

A. the router handles the overflow of traffic by using FIFO B. the router handles the possible buildup of congestion by using WRED 

C. the router forces inbound and outbound traffic to stay within a defined profile by using rate limiting 

D. the router separates packets based on certain characteristics by using NBAR 

E. the router marks packets based on certain characteristics by using PBR 

Answer:


Q108. You are designing an IPv4 any source multicast redundancy solution. Which technology ensures the quickest RP convergence? 

A. Auto-RP 

B. Embedded RP 

C. bootstrap router 

D. MSDP anycast RP 

Answer:


Q109. You are designing a wireless LAN with the following components: 

High-density indoor access point deployment 

2.4-GHz and 5-GHz radios 

802.11a, 802.11g, and 802.11n mode wireless LAN clients 

Site survey results show negligible foreign WiFi and non-WiFi interference. What is the best method to decrease duty cycle (radio frequency utilization) and increase overall wireless LAN client performance for this design? 

A. Disable all data rates below 12 Mb/s on all access points. 

B. Decrease radio transmit power on all access points that report a high duty cycle. 

C. Increase radio transmit power on all access points that report a high duty cycle. 

D. Disable all data rates above 12 Mb/s on all access points. 

E. Increase radio transmit power on all access points. 

Answer:


Q110. How should multiple OSPF areas be designed when deployed on a classic three-layer (core/distribution/access) network hierarchy? 

A. The OSPF flooding domain boundary should be at the edge of the core layer. 

B. The OSPF flooding domain boundary should be within the distribution layer. 

C. OSPF should generally be deployed in a three-layer domain hierarchy to align with the physical three-layer hierarchy. 

D. OSPF flooding domain boundaries should be placed with route aggregation in mind.
