Question 1

An architect must address sustained congestion on the access and distribution uplink of network. QoS has already been implemented and optimized, but it is no longer effective in ensuring optimal network performance. Which two solutions should the architect use to improver network performance? (Choose two)

AReconfigure QoS based on the IntServ model

BUtilize random early detection to manage queues

CImplement higher-speed uplink interfaces

DBundle additional uplinks into logical EtherChannels

EConfigure selective packet discard to drop noncritical network traffic.

Answer : B, E

Question 2

A global organization with several branches hired a network architect to design an overlay VPN solution. The branches communicate with each other frequently. The customer expects to add more branches in the future. To meet the customer's security requirements, the architect plans to provide traffic protection using dynamic IPsec tunnels. Which solution should the architect choose?

ADMVPN

BEasyVPN

CGETVPN

DL2TP

Answer : A

Question 3

An engineer is designing a network for a customer running a wireless network with a common VLAN for all APs. The customer is experiencing unicast flooding in the Layer 2 network between the aggregation and access layers. The customer wants to reduce the flooding and improve convergence time. Which solution meets these requirements?

AMigrate all APs to a common Layer 2 access layer switch and run Layer 3 from the aggregation layer to all remaining access layer switches.

BAlign HSRP primary and STP root bridges and reduce ARP timers to match CAM timers on the aggregation layer switches.

CMigrate to a Layer 3 access campus design if the APs can run on separate VLANs.

DAlign HSRP primary and STP root bridges if the APs cannot run on separate VLANs.

Answer : D

Question 4

When a first hop redundancy solution is designed, which protocol ensures that load balancing occurs over multiple routers using a single virtual IP address and multiple virtual MAC addresses?

AGLBP

BIRDP

CVRRP

DHSRP

Answer : A

Question 5

Refer to the exhibit.

Refer to the exhibit. An engineer is designing an OSPF solution for a customer. The design must take into consideration:

Application load balancers D. E. and F are in different geographical locations and are OSPF-enabled.

Hosts A, B. and C connect to an application through the load balancers using IP address 10.1.1.1/32.

In the event of a failure of one of the load balancers, hosts must still have access to the application.

Which solution must the engineer choose?

AAll load balancers to be co-located in area 0.

BX, Y, and Z to be configured as different areas

CAt least one load balancer to be in area 0.

DX, Y and Z to be configured as the same area

Answer : A

Question 6

Refer to the exhibit.

Refer to the exhibit. An engineer proposed this solution for a company that requires a loop-free. Layer 2 network design. The network will run 802.1W, and all links will be 1 Gbps. If all interfaces are up as point- to-point adjacencies, what are the expected port end states based on the design?

AEth1/2 on SW2 and SW3 will be in a Desg FWD state

BEth1/3 on SW2 and SW3 will be m an Attn BLK state

CEth1/2 on SW3 and SW4 will be m an Attn BLKbtate.

DEth1/1 on SW1 and SW2 will be in a Root FWD state.

Answer : C

Question 7
