  C. autonomy and control over hardware
  D. access to industrial-strength storage and computing power
  A. lower initial costs

• Question 317:

  An architect is creating a migration strategy for a large organization in which the choice made by the application between IPv6 and IPv4 is based on the DNS request. Which migration strategy does the architect choose?

  A. AFT for public web presence
  B. host-initiated tunnels
  C. dual stack
  D. site-to-site IPv6 over IPv4 tunnels
  C. dual stack

• Question 318:

  What is the easiest way to enable SD-Access for all your remote sites after you have your campus SD-Access fabric up and running?

  A. Treat all the sites as one fabric domain and use the traditional physical network as the underlay.
  B. Use a separate fabric domain for each site and use the traditional physical network as the underlay.
  C. Use a separate fabric domain for each site and use SD-WAN as the underlay
  D. Treat all the sites as one fabric domain and use SD-WAN as the underlay
  A. Treat all the sites as one fabric domain and use the traditional physical network as the underlay.

• Question 319:

  Which topology within a network underlay eliminates the need for first hop redundancy protocols while improving fault tolerance, increasing resiliency, and simplifying the network?

  A. virtualized topology
  B. routed access topology
  C. Layer 2 topology
  D. logical fabric topology
  B. routed access topology

• Question 320:

  

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

  1.Application load balancers

  D.

  E. and F are in different geographical locations and are OSPF-enabled.

  2.Hosts A,

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

  3.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?
