Cisco 350-401 Online Questions & Answers

• Question 141:

  Refer to the exhibit.

  

  The inside and outside interfaces in the NAT configuration of this device have been correctly identified.

  What is the effect of this configuration?

  A. dynamic NAT
  B. NAT64
  C. PAT
  D. static NAT
  C. PAT

  ---

  Explanation

  The command "ip nat inside source list 1 interface gigabitethernet0/0 overload" translates all source addresses that pass access list 1, which means 172.16.1.0/24 subnet, into an address assigned to gigabitethernet0/0 interface. Overload keyword allows to map multiple IP addresses to a single registered IP address (many- to-one) by using different ports so it is called Port Address Translation (PAT).

• Question 142:

  In a traditional 3 tier topology, an engineer must explicitly configure a switch as the root bridge and exclude it from any further election process for the spanning-tree domain. Which action accomplishes this task?

  A. Configure the spanning-tree priority to 32768
  B. Configure root guard and portfast on all access switch ports.
  C. Configure BPDU guard in all switch-to-switch connections.
  D. Configure the spanning-tree priority equal to 0.
  B. Configure root guard and portfast on all access switch ports.

  ---

  Explanation

  Root guard does not allow the port to become a STP root port, so the port is always STP-designated. If a better BPDU arrives on this port, root guard does not take the BPDU into account and elect a new STP root. Instead, root guard puts the port into the root-inconsistent STP state which is equal to a listening state. No traffic is forwarded across this port.

• Question 145:

  Which of the following statements are true regarding the Link Management Protocol (LMP) when used in the Cisco Stackwise virtual link? (Choose two.)

  A. It determines the switch priority.
  B. It negotiates the version of the virtual header
  C. It verifies link integrity via bidirectional forwarding
  D. It performs auto discovery of other active Stackwise switches
  B. It negotiates the version of the virtual header
  C. It verifies link integrity via bidirectional forwarding

  ---

  Explanation

  The Link Management Protocol (LMP) is activated on each link of the StackWise Virtual link as soon as it is brought up online. The LMP performs the following functions:

  1. Verifies link integrity by establishing bidirectional traffic forwarding, and rejects any unidirectional links 2. Exchanges periodic hellos to monitor and maintain the health of the links 3. Negotiates the version of StackWise Virtual header between the switches StackWise Virtual link role resolution

• Question 146:

  Refer to the exhibit. An engineer configures OSPF and wants to verify the configuration

  

  Which configuration is applied to this device?

  A. R1(config)#router ospf 1R1(config-router)#network 192.168.50.0 0.0.0.255 area 0
  B. R1(config)#router ospf 1R1(config-router)#network 0.0.0.0 0.0.0.0 area 0R1(config-router)#no passive-interface Gi0/1
  C. R1(config)#interface Gi0/1R1(config-if)#ip ospf enableR1(config-if)#ip ospf network broadcastR1(config-if)#no shutdown
  D. R1(config)#interface Gi01R1(config-if)#ip ospf 1 area 0R1(config-if)#no shutdown
  D. R1(config)#interface Gi01R1(config-if)#ip ospf 1 area 0R1(config-if)#no shutdown

  Explanation

  When you ue the "show ip ospf interface intx/x/x" command, what difference will you see in the old vs new OSPFv2 config?

  - One will say attached via Interface Enable, the other will say Attached via Network Statement https://www.chegg.com/flashcards/chapter-20-implementing-ospf-61b573b4-141b-4f63-bac9-ee35462d315e/deck

  Topology

  

  Tasks

  Configure OSPF on both routers according to the topology to achieve these goals:

  1. Ensure that all networks are advertised between the routers without using the “network” statement under the “router ospf” configuration section.

  2. Configure a single command on both routers to ensure:

  The DR/BDR election does not occur on the link between the OSPF neighbors.

  No extra OSPF host routes are generated.
