• Question 322:

  A company wants to switch from static to dynamic routing. The branches use DMVPN back to the hub using two internet connections. One internet connection speed is 10 Mbps, and the other is 100 Mbps. All locations use Cisco routers; however, the branch routers have limited memory and CPU resources. Which routing protocol and design solution must the company choose for optimal traffic forwarding during peak traffic times?

  A. OSPF deployed in area 0 with branch routers connected back via virtual links
  B. EIGRP with branch routers as stub routers and variance enabled
  C. ISIS with the hub and spoke routers configured in two different areas
  D. iBGP with the hub routers set up as route reflectors
  B. EIGRP with branch routers as stub routers and variance enabled

• Question 323:

  How is internet access provided to a WAN edge router that is connected to a MPLS transport link?

  A. OMP advertises a default route from a WAN Edge router that is connected to the MPLS and internet transport networks
  B. Internet access must be provided at the WAN Edge router through either a 4G/5G link or local Internet circuit
  C. An extranet must be provided in the MPLS transport network to allow private traffic to reach the public internet
  D. TLOC extensions are used to route traffic to a WAN Edge router that is connected to the Internet transport network
  D. TLOC extensions are used to route traffic to a WAN Edge router that is connected to the Internet transport network

• Question 324:

  An engineer is designing a QoS solution for a campus. The design must guarantee real-time traffic delivery during congestion, minimize the bandwidth consumption for possible virus or worm attacks, and reduce flooding of excessive traffic during times of congestion. Which two solutions must the engineer select? (Choose two.)

  A. Create a policing policy to drop excessive traffic and a strict queue for real-time traffic
  B. Apply queuing on the distribution to core links
  C. Create a scavenger queue for excessive traffic and a strict queue for real-time traffic
  D. Apply queuing on the access to distribution links
  E. Create a shaping policy to drop excessive traffic and a strict queue for real-time traffic
  C. Create a scavenger queue for excessive traffic and a strict queue for real-time traffic
  D. Apply queuing on the access to distribution links

• Question 325:

  Which two activities should occur during an SE's discovery process? (Choose two.)

  A. Gathering information about the current state of the customer s network environment
  B. Working with the customer to develop a reference architecture
  C. Mapping Cisco innovation to customer s needs
  D. Referencing the PPDIOO model to effectively facilitate the discussion
  E. Establishing credibility with the customer
  A. Gathering information about the current state of the customer s network environment
  E. Establishing credibility with the customer

• Question 326:

  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?

  A. DMVPN
  B. EasyVPN
  C. L2TP
  D. GETVPN
  A. DMVPN

• Question 327:

  Currently, inter-VRF routing between the global routing table and VRF-A is accomplished on the client firewall, but the customer wants to do this on the core network layer. The customer does not want to run BGP, VRF-Lite, or static routing. Which mechanism meets the requirements?

  A. inter-VRF can only be used on an external device with a link in each VRF
  B. policy-based routing with the global set statement in a route map
  C. route map that matches access lists and prefix lists with the import feature
  D. VRF receive feature under the global routing interfaces
  D. VRF receive feature under the global routing interfaces

• Question 328:

  Refer to the exhibit. Where must an architect plan for route summarization for the topology?

  

  A. from the core toward the aggregation and the access toward the aggregation
  B. from the core toward the aggregation and the aggregation toward the core
  C. from the aggregation toward the access and the access toward the aggregation
  D. from the aggregation toward the core and the aggregation toward the access
  D. from the aggregation toward the core and the aggregation toward the access

• Question 329:

  A network engineer must connect two sites across a public network using a secure tunneling technology that supports multicast traffic. Which technology must be chosen?

  A. IPsec
  B. GRE
  C. PPTP
  D. GRE over IPsec
  D. GRE over IPsec

• Question 330:

  An engineer is designing an EIGRP network for a small branch site where there is only one Layer 3 router. The engineer wants the router to advertise the local LAN network to remote EIGRP neighbors without sending any unnecessary multicast messages on the local LAN. Which action should the engineer take?

  A. Use a static default route for this site instead of EIGRP
  B. Advertise the local LAN using the network command and the passive-interface feature
  C. Redistribute the local LAN network using the redistribute connected command
  D. Advertise the local LAN subnet as a stub network
  B. Advertise the local LAN using the network command and the passive-interface feature
