A.ITR B.ETR C.MS D.MR Answer: B QUESTION NO: 4 © Copyright Prep Solutions Limited, All rights reserved

  2. You have configured router R1 with multiple VRF’s in order to support multiple customer VPN networks. If you wanted to see the best path for the 10.2.1.0.24 route in VRF Green, what command would you use? A.show ip route vrf Green 10.2.1.0 B.show ip route 10.2.1.0 vrf Green C.show route all 10.2.1.0 D.show ip route 10.2.1.0 Green Answer: A QUESTION NO: 5 What is the fundamental difference between a Type 1 hypervisor and a Type 2 hypervisor in a virtualized environment? A.Type 1 hypervisors run directly on the hardware and type 2 hypervisors require an underlying operating system. B.Type 2 hypervisors run directly on the hardware and type 1 hypervisors require an underlying operating system. C.Type 2 Answer: A QUESTION NO: 6 Which of the following are benefits from implementing the use of VXLAN’s in a network? (Choose two) A.Increased scalability since VXLAN extends the IF field to 24 bits, providing up to 16 million unique ID values. B.Makes the implementation of Spanning Tree more efficient. C.Can be used to replace layer 3 routing protocols and increase routing efficiency at layer 2. D.Supports Equal Cost Multi-pathing (ECMP) so that load balancing over multiple links can be used. Answer: A, D QUESTION NO: 7 Which component of TCP defines the maximum packet size that a host interface is able to accept on ingress? © Copyright Prep Solutions Limited, All rights reserved

  3. A.MTU B.PATH MTU C.Window size D.MRU Answer: D QUESTION NO: 8 Which of the following are examples of Type 2 hypervisors?
