An architect must create a QoS solution for a customer to ensure that a 40 Mbps Internet connection is shared between four subnets based on these requirements: * Each subnet must receive no less than 10 Mbps of download bandwidth during peak traffic times. * A subnet can use up to 40 Mbps during nonpeak traffic times if the other subnets are idle. * Download traffic must never experience a delay. Which solution must the architect choose?
An engineer must design a QoS solution for a customer. The network currently supports data only, but the customer will roll out VoIP and IP video in conjunction with the new QoS solution. The engineer plans to use DiffServ. To ensure priority for voice services, which model must the design include?

Refer to the exhibit. An engineer must design a WAN solution so that ISP-1 is always preferred over ISP-2. The path via ISP-2 is considered as a backup and must be used only when the path to ISP-1 is down. Which solution must the engineer choose? A. R1: - Routes advertised to ISP-1: 0x AS-path prepend - Routes received from ISP-1: HIGH local-preference - Routes advertised to R2: no action - Routes received from R2: community NO-EXPORT R2: - Routes advertised to ISP-2:5x AS-path prepend - Routes received from ISP-2: LOW local-preference - Routes advertised to R1: community NO-ADVERTISE - Routes received from R1: no action

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?

A.

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

Answers
A.

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

B.

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

Answers
B.

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

C.

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

Answers
C.

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

D.

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