• Question 151:

  An international media provider is an early adopter of Docker and micro services and is using an open-source homegrown container orchestration system. A few years ago, they migrated from on-premises data centers to the cloud Now they are faced with challenges related to management of the deployed services with their current homegrown orchestration system.

  Which platform is well-suited as a state-aware orchestration system?

  A. Puppet
  B. Kubemetes
  C. Ansible
  D. Terraform
  B. Kubemetes

• Question 152:

  An organization is working on a design solution for a new Internet-based remote access virtual private network that has 1000 remote sites.

  A network administrator recommends GETVPN as the model

  What is a potential problem of using GETVPN in this situation?

  A. GETVPN is not scalable to a large number of remote sites
  B. GETVPN key servers would be on public hacker-reachable space and need higher security
  C. GETVPN and DMVPN do not interoperate
  D. GETVPN requires a high level of background traffic to maintain its IPsec SAs
  B. GETVPN key servers would be on public hacker-reachable space and need higher security

• Question 153:

  A financial company requires that a custom TCP-based stock-trading application be prioritized over all other traffic for the business due to the associated revenue. The company also requires that VoIP be prioritized for manual trades. Which directive should be followed when a QoS strategy is developed for the business?

  A. Allow VoIP and the custom application to share the same priority queue,
  B. The custom application and VoIP must be assigned their own separate priority queue.
  C. Interleave the custom application with other TCP applications in the same CBWR
  D. Avoid placing the custom application in a CBWFQ queue that contains other
  B. The custom application and VoIP must be assigned their own separate priority queue.

• Question 154:

  A service provider hires you to design its new managed CE offering to meet these requirements

  1.The CEs cannot run a routing protocol with the PE

  2.Provide the ability for equal or unequal ingress load balancing in dual-homed CE scenarios.

  3.Provide support for IPv6 customer routes

  4.Scale up to 250.000 CE devices per customer.

  5.Provide low operational management to scale customer growth.

  6.Utilize low-end (inexpensive) routing platforms for CE functionality.

  Which tunneling technology do you recommend?

  A. FlexVPN
  B. point-to-point GRE
  C. DMVPN
  D. LISP
  D. LISP

• Question 155:

  A software-defined networking (SDN) controller teams network topology information by using BGP link-state sessions with the route reflectors of an MPLS-enabled network.

  The controller then uses the topology information to apply on- demand traffic policies to the network through a protocol that is supported from all Layer 3 routers Each policy is represented as a RIB entry in the control plane of the router.

  Which SDN model has been implemented?

  A. SDN centralized
  B. SDN traffic engineering
  C. SD-WAN
  D. SDN hybrid
  B. SDN traffic engineering

• Question 156:

  Retef to the exhibit.

  

  This network is running OSPF and EIGRP as the routing protocols Mutual redistribution of the routing protocols has been contoured on the appropriate ASBRs The OSPF network must be designed so that flapping routes m EIGRP domains do not affect the SPF runs within OSPF The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains.

  Which technique accomplishes the requirement?

  A. route summarization the ASBR interfaces facing the OSPF domain
  B. route summarization on the appropriate ASBRS.
  C. route summarization on the appropriate ABRS.
  D. route summarization on EIDRP routers connecting toward the ASBR
  D. route summarization on EIDRP routers connecting toward the ASBR

• Question 157:

  DRAG DROP

  When a detection system for protecting a network from threats sourced from the Internet is designed there are two common deployment methods, where the system is placed differently relative to the perimeter firewall.

  An unfiltered detection system examines the raw Internet data streams before it reaches the firewall.

  A screened detection solution which monitors traffic that is allowed through the firewall Both have its advantages and disadvantages drag and drop the characteristics on the left to the corresponding category on the right in no particular order.

  Select and Place:

  

  

• Question 158:

  Which two statements explain the operation of BFD asynchronous mode? (Choose two )

  A. BFD asynchronous mode with echo packets combines the control packets and echo packets into a single packet.
  B. BFD asynchronous mode without echo packets uses control packets, and BFD asynchronous mode with echo packets does not.
  C. BFD asynchronous mode with and without echo packets use control packets.
  D. BFD asynchronous without echo packets has control packets sent back to the originating router, which echoes the control packet to detect failures.
  E. BFD asynchronous mode with echo packets uses separate control packets and echo packets.
  C. BFD asynchronous mode with and without echo packets use control packets.
  E. BFD asynchronous mode with echo packets uses separate control packets and echo packets.

• Question 159:

  An engineer is designing a DMVPN network where OSPF has been chosen as the routing protocol A spoke-to-spoke 'J

  Which two design considerations must be taken into account? (Choose two )

  A. Configure all the sites as network type broadcast
  B. The network type on all sites should be point-to-multipoint
  C. The network type should be point-to-multipoint for the hub and point-to-point for the spokes.
  D. The hub should be set as the DR by specifying the priority to 255.
  E. The hub should be the DR by changing the priority of the spokes to 0.
  A. Configure all the sites as network type broadcast
  E. The hub should be the DR by changing the priority of the spokes to 0.

• Question 160:
