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?

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

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.

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

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

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

Refer to the exhibit. An architect must design an IPv6 migration solution for an enterprise customer to support these requirements:* Clients will transition to the new IPv6 network, which provides NAT64 and IPv6 DNS resolution services, using the same DNS name that points to the IPv4 address.* The service provider will create a client-facing IPv6 interface with a new IPv6 virtual address that points to the same IPv4 DNS server.* The service provider will support clients that use global IPv6 addresses and encapsulate IPv4 packets into IPv6 tunnels.Which two migration solutions must the architect choose? (Choose two.)

Use dual-stack lite from the devices to the core MPLS network.

Use NAT44/64 from the MPLS network to the IGR.

Use dual-stack lite from the MPLS network to the IGR.

Use IPv6 tunneling from the devices to the core MPLS network.

Use dual-stack lite from the devices to the core MPLS network.

Use NAT44/64 from the MPLS network to the IGR.

Use NAT44/64 from the devices to the core MPLS network.

An engineer is designing an IPv4 addressing plan for an enterprise with 1000 branches. Each branch requires a prefix for data and a prefix for voice. Each prefix must accommodate up to 128 hosts, and prefixes must facilitate summarization at aggregation points in the network. The security team requires a simple method for identifying voce prefixes. Which allocation does the engineer recommend from the RFC1918 address space?

/24 prefixes for data from 10.0.0.0/8 and /24 prefixes for voice from the next contiguous /24 prefix per site

/24 prefixes for data from 10.0.0.0/15 and /24 prefixes for voice from 172.16.0.0/15

/24 prefixes for data from 10.0.0.0/8 and /24 prefixes for voice from the next contiguous /24 prefix per site

/25 prefixes for data from 10.0.0.0/8 end /25 prefixes for voice from the next contiguous /25 prefix per branch

/24 prefixes for data from 10.0.0.0/8 and /24 prefixes for voice from 172.16.0.0/12Answer: B

An engineer is designing a PIM Anycast RP solution between two data centers. The design must ensure that RP1 in DC1 and RP2 in DC2 inform each other about specific sources that have joined locally. Which solution must the engineer choose?

Enable MSDP between RPs using separate unique loopback interfaces

Provision the RPs on the same IP subnet and extend the subnet at Layer 2 between data centers

Enable MSDP between RPs using separate unique loopback interfaces

Enable MSDP between RPs using the configured Anycast RP address

No action is required because PIM registers from the source will, by default, reach each RP

An engineer is designing a BGP network for a large customer. To permit efficient scaling, the BGP domain is split into clusters. Which peering solution should be used between the route reflectors in different clusters for the BGP routes to be propagated appropriately?

The route reflectors should be nonclients with regards to each other.

The route reflectors should be made dents of each other.

The route reflectors should be nonclients with regards to each other.

The route reflectors should not have any kind of BGP peering.

The route reflectors should have peering through another nonclient router.

A company uses cloud-based applications for voice and video calls, file sharing, content sharing, and messaging. During business hours, these applications randomly become slow and unresponsive.However, other applications work smoothly with the current applied QoS polices. Which solution must the company choose to resolve the issue?

Identify the applications with NBAR2 and allocate the required bandwidth accordingly.

Identify the port used by each application and apply a minimum bandwidth guarantee.

Identify the applications and reserve the required bandwidth on the perimeter routers.

Identify the application ports, create groupings, and rate-limit the required bandwidth.

Which design achieves SD-WAN control plane redundancy?

Using multiple instances of vManage in clusters

Configuring BFD on the WAN Edge routers

Using multiple instances of vManage in clusters

Deploying using a virtual platform like UCS or CSP

Managing the underlay network with OMP

A network engineer must design an MSDP multicast solution to provide RP resilience in a network with two separate domains. Also, multicast sources and receivers must register with the local RP.Which solution must the engineer choose?

Configure the RP loopback interface with the same IP address/32, and traffic will route to the closest RP

Configure the RP has value to 0, and traffic will route to the closest RP

Configure the RP loopback interface with the same IP address/32, and traffic will route to the closest RP

Configure the RP group ranges to split the multicast traffic, and traffic will route to the longest match

Configure the RP priority with the same value, and traffic will route to the closest RP
