  A. Prevent polling of large tables through the use of SNMP OID restnctions
  B. Disable unused 01 Ds and MIBs on the NMS systems
  C. Increase the SNMP process priority
  D. Implement SNMP community restrictions that are associated with an ACL
  E. Unload unused MIBs from the network devices
  A. Prevent polling of large tables through the use of SNMP OID restnctions
  D. Implement SNMP community restrictions that are associated with an ACL

• Question 203:

  Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to monitor and keep track of any performance issues by continuously collecting and analyzing statistical information to monitor, correct, and optimize any reduced responsiveness across the network. Which layer accomplishes this design requirement?

  A. fault management
  B. accounting management
  C. performance management
  D. security management
  A. fault management

• Question 204:

  During evaluation of migrating current on premises infrastructure to add cloud-based infrastructure, a network planning team must meet three core requirements as they make recommendations on which cloud strategy to adopt going forward

  1.Technology is changing rapidly, therefore the enterprise must be open to adopting new ways of doing things, and be ready to invest CapEx-funds in the next three years

  2.Network bandwidth capacity requirements are dynamic and are expected to change over the next year

  3.If new technologies are to be introduced, operational expenses must be kept at a minimum. Which cloud strategy meets these requirements?

  A. private
  B. hybrid
  C. public
  D. multicloud
  B. hybrid

• Question 205:

  In a redundant hub and spoke "wheel" design, all spokes are connected to the hub, and spokes are connected to other spokes as well. During failure on one spoke link, the traffic from that site can be sent to a neighboring site for it to be forwarded to the hub site. But during peak hours, a link is overloaded and traffic is re-routed to a neighbor, which subsequently becomes overloaded. This overload results in network traffic oscillation as the load varies at each spoke site. This design provides more redundancy but not more resiliency because the routing protocol must process many alternate paths to determine the lowest cost path.

  Which two design changes help to improve resilience in this case? (Choose two.)

  A. Increase the number of redundant paths considered during the routing convergence calculation.
  B. Eliminate links between every spoke.
  C. Increase routing protocol convergence timers.
  D. Increase unequal-cost parallel paths.
  E. Use two links to each remote site instead of one.
  B. Eliminate links between every spoke.
  E. Use two links to each remote site instead of one.

• Question 206:

  An enterprise solution team is performing an analysis of multilayer architecture and multicontroller SDN solutions for multisite deployments. The analysis focuses on the ability to run tasks on any controller via a standardized interface. Which requirement addresses this ability on a multicontroller platform?

  A. Deploy a root controller to gather a complete network-level view.
  B. Use the East-West API to facilitate replication between controllers within a cluster.
  C. Build direct physical connectivity between different controllers.
  D. Use OpenFlow to implement and adapt new protocols.
  B. Use the East-West API to facilitate replication between controllers within a cluster.

• Question 207:

  Company XYZ plans to run OSPF on a DMVPN network. They want to use spoke-to-spoke tunnels in the design. What is a drawback or concern in this type of design?

  A. Additional host routes will be inserted into the routing tables
  B. Manual configuration of the spokes with the appropriate priority will be needed
  C. There will be split-horizon issue at the hub
  D. Manual configuration of the spoke IP address on the hub will be needed
  B. Manual configuration of the spokes with the appropriate priority will be needed

• Question 208:

  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 209:

  How many fully established neighbour relationships exist on an Ethernet with five routers running OSPF as network type broadcast?

  A. 5
  B. 6
  C. 7
  D. 10
  E. 20
  C. 7

• Question 210:

  Which two areas of business presents a technical solution to support the company during emergency situations by understanding the data flows and using business processes to expiam how it answers to business needs and enables the business to improve'? (Choose two.)

  A. decentralized device management
  B. BYOD policy
  C. disaster recovery
  D. centralized device management
  E. business continuity
  C. disaster recovery
  E. business continuity
