Cisco 350-401 Online Questions & Answers

• Question 161:

• Question 162:

  What is the function of a VTEP in VXLAN?

  A. provide the routing underlay and overlay for VXLAN headers
  B. dynamically discover the location of end hosts in a VXLAN fabric
  C. encapsulate and de-encapsulate traffic into and out of the VXLAN fabric
  D. statically point to end host locations of the VXLAN fabric
  C. encapsulate and de-encapsulate traffic into and out of the VXLAN fabric

  ---

  Explanation

  VXLAN Tunnel Endpoint

  The VTEP device uses this IP address to encapsulate Ethernet frames and transmits the encapsulated packets to the transport network through the IP interface.

• Question 163:

  Using the EIRP formula, what parameter is subtracted to determine the EIRP value?

  A. transmitter power
  B. antenna cable loss
  C. antenna gain
  D. signal-to-noise ratio
  B. antenna cable loss

  ---

  Explanation

  Once you know the complete combination of transmitter power level, the length of cable, and the antenna gain, you can figure out the actual power level that will be radiated from the antenna. This is known as the effective isotropic radiated power (EIRP), measured in dBm. EIRP is a very important parameter because it is regulated by governmental agencies in most countries. In those cases, a system cannot radiate signals higher than a maximum allowable EIRP. To find the EIRP of a system, simply add the transmitter power level to the antenna gain and subtract the cable loss.

• Question 164:

  Refer to the exhibit.

  

  A network engineer is configuring OSPF between router R1 and router R2. The engineer must ensure that a DR/BDR election does not occur on the Gigabit Ethernet interfaces in area 0.

  Which configuration set accomplishes this goal?

  A. R1(config-if)interface Gi0/0 R1(config-if)ip ospf network point-to-point R2(config-if)interface Gi0/0 R2(config-if)ip ospf network point-to-point
  B. R1(config-if)interface Gi0/0 R1(config-if)ip ospf network broadcast R2(config-if)interface Gi0/0 R2(config-if)ip ospf network broadcast
  C. R1(config-if)interface Gi0/0 R1(config-if)ip ospf database-filter all out R2(config-if)interface Gi0/0 R2(config-if)ip ospf database-filter all out
  D. R1(config-if)interface Gi0/0 R1(config-if)ip ospf priority 1 R2(config-if)interface Gi0/0 R2(config-if)ip ospf priority 1
  A. R1(config-if)interface Gi0/0 R1(config-if)ip ospf network point-to-point R2(config-if)interface Gi0/0 R2(config-if)ip ospf network point-to-point

  ---

  Explanation

  Broadcast and Non-Broadcast networks elect DR/BDR while Point-to-point/multipoint do not elect DR/BDR. Therefore we have to set the two Gi0/0 interfaces to point-to-point or point-to-multipoint network to ensure that a DR/BDR election does not occur.

• Question 170:

  Refer to the exhibit.

  

  Security policy requires all idle-exec sessions to be terminated in 600 seconds.

  Which configuration achieves this goal?

  A. line vty 0 15 absolute-timeout 600
  B. line vty 0 15 exec-timeout
  C. line vty 0 15 exec-timeout 10 0
  D. line vty 0 4 exec-timeout 600
  C. line vty 0 15 exec-timeout 10 0

  ---

  Explanation

  The "exec-timeout" command is used to configure the inactive session timeout on the console port or the virtual terminal. The syntax of this command is:

  exec-timeout minutes [seconds]

  Therefore we need to use the "exec-timeout 10 0" command to set the user inactivity timer to 600 seconds (10 minutes).
