• Question 102:

  Refer to the exhibit.

  

  This network is running legacy STP 802.1 d. Assuming "hello_timer" is fixed to 2 seconds, which parameters can be modified to speed up convergence times after single link/node failure?

  A. Only the maximum_transmission_halt_delay and diameter parameters are configurable parameters in 802.1d to speed up STP convergence process.
  B. The max_age and forward delay parameters can be adjusted to speed up STP convergence process.
  C. The transit_delay=5 and bpdu_delay=20 are recommended values, considering hello_timer=2 and specified diameter.
  D. Only the transit_delay and bpdu_delay timers are configurable parameters in 802.1d to speed up STP convergence process.
  B. The max_age and forward delay parameters can be adjusted to speed up STP convergence process.

• Question 103:

  Enterprise XYZ wants to implement fast convergence on their network and optimize timers for OSPF However they also want to prevent excess flooding of LSAs if there is a constantly flapping link on the network. Which timers can help prevent excess flooding of LSAs for OSPF?

  A. OSPF propagation timers
  B. OSPF throttling timers
  C. OSPF delay timers
  D. OSPF flooding timers
  B. OSPF throttling timers

• Question 104:

  Organic growth or decline comes from a company's normal business activities, rather than through acquisitions or divestment. Changes in usage patterns can also cause organic change in network requirements. Which tool is useful when designing and operationalizing a network that is in the process of change?

  A. change management
  B. modularity
  C. mobility
  D. monitoring
  A. change management

• Question 105:

  Your company wants to deploy a new data center infrastructure Based on the requirements you have chosen VXLAN as encapsulation technology The customer is concerned about miss-configuration of Layer 2 devices and DC wide outages caused by Layer 2 loops.

  What do you answer?

  A. VXLAN offers native loop avoidance mechanism
  B. Storm Control should be enabled on all ports
  C. VPC+ could prevent L2 loop on access ports
  D. BPDU Guard should be enabled on all VTEP access ports
  D. BPDU Guard should be enabled on all VTEP access ports

• Question 106:

  DRAG DROP

  Drag and drop the correct mitigation methods from the left onto the corresponding types of attack on the right.

  Select and Place:

  

  

• Question 107:

  A large enterprise customer has a single router that uses two active/active 10-Mbps internet links in one of its offices. Each link currently handles approximately 7 Mbps of traffic, which is close to the full link capacity.

  When a link fails, the failure leads to significantly degraded performance of all applications. Static routing is used. The current ISP cannot deliver additional bandwidth capacity on the existing links.

  The customer needs a network design that is resistant to failure, but does not increase CAPEX.

  Which solution should be proposed to the customer?

  A. Implement quality of service on the current links.
  B. Add a third link to the current router.
  C. Add an additional edge router connected to a second ISP.
  D. Use dynamic routing for equal-cost multipath.
  D. Use dynamic routing for equal-cost multipath.

• Question 108:

  You want to split an Ethernet domain in two.

  Which parameter must be unique in this design to keep the two domains separated?

  A. VTP domain
  B. VTP password
  C. STP type
  D. VLAN ID
  D. VLAN ID

• Question 109:

  While designing a switched topology, in which two options is UplinkFast recommended? (Choose two )

  A. when switches of different spanning-tree types are connected (for example. 802.1d connecting to 802.1w)
  B. on distribution layer switches
  C. when hello timers are changed to more aggressive values
  D. on access layer switches
  E. on the core switches
  A. when switches of different spanning-tree types are connected (for example. 802.1d connecting to 802.1w)
  D. on access layer switches

• Question 110:

  Refer to the exhibit.

  

  OSPF is running as the IGP to provide reachability to all AS100 networks R3 and R4 are the current ABRs at the boundary of OSPF Area0 and Areal Now BGP must be deployed within AS 100 because it will be receiving Internet routes from its eBGP peers (the service provider) connected to R1 and R2. What is an optimal solution for this deployment to configure BGP relationships and redistribute BGP learned routes into OSPF?

  A. R5 should be configured as a route reflector for R1, R2, R3 and R4. BGP routes must be redistributed at R1 and R2 into OSPF.
  B. Configuration should be set up with R1 and R2, and R3 in one sub AS, with and R4 in another, and redistribution at R1 and R2.
  C. A full mesh should be deployed between all the routers with mutual redistribution to take place at R1 and R2.
  D. R1, R2, R3 and R4 must be set up with a neighbor relationship with R5 only must not be a route reflector.
  A. R5 should be configured as a route reflector for R1, R2, R3 and R4. BGP routes must be redistributed at R1 and R2 into OSPF.
