Cisco 350-401 Online Questions & Answers

• Question 611:

  Which method provides failure detection in BFD?

  A. short duration, high overhead
  B. short duration, low overhead
  C. long duration, high overhead
  D. long duration, low overhead
  B. short duration, low overhead

• Question 612:

  What is one main REST security design principle?

  A. separation of privilege
  B. password hashing
  C. confidential algorithms
  D. OAuth
  A. separation of privilege

  ---

  Explanation

  Separation of Privilege: Granting permissions to an entity should not be purely based on a single condition, a combination of conditions based on the type of resource is a better idea.

• Question 613:

  Which action is a function of VTEP in VXLAN?

  A. tunneling traffic from IPv6 to IPv4 VXLANs
  B. allowing encrypted communication on the local VXLAN Ethernet segment
  C. encapsulating and de-encapsulating VXLAN Ethernet frames
  D. tunneling traffic from IPv4 to IPv6 VXLANs
  C. encapsulating and de-encapsulating VXLAN Ethernet frames

  ---

  Explanation

  VTEPs connect between Overlay and Underlay network and they are responsible for encapsulating frame into VXLAN packets to send across IP network (Underlay) then decapsulating when the packets leaves the VXLAN tunnel.

  

• Question 614:

  Why would a small or mid-size business choose a cloud solution over an on-premises solution?

  A. Cloud provides greater ability for customization than on-premises.
  B. Cloud provides more control over the implementation process than on-premises.
  C. Cloud provides lower upfront cost than on-premises.
  D. Cloud provides higher data security than on-premises.
  C. Cloud provides lower upfront cost than on-premises.

• Question 615:

  Refer to the exhibit.

  

  Which statement about the OPSF debug output is true?

  A. The output displays all OSPF messages which router R1 has sent to received on interface Fa0/1.
  B. The output displays all OSPF messages which router R1 has sent or received on all interfaces.
  C. The output displays OSPF hello messages which router R1 has sent received on interface Fa0/1.
  D. The output displays OSPF hello and LSACK messages which router R1 has sent or received.
  C. The output displays OSPF hello messages which router R1 has sent received on interface Fa0/1.

  Explanation

  This combination of commands is known as "Conditional debug" and will filter the debug output based on your conditions. Each condition added, will behave like an `And' operator in Boolean logic. Some examples of the "debug ip ospf hello" are shown below:

• Question 617:

  If a VRRP master router fails, which router is selected as the new master router?

  A. router with the highest priority
  B. router with the highest loopback address
  C. router with the lowest loopback address
  D. router with the lowest priority
  A. router with the highest priority

  In the "Basic VRRP Topology" figure, if Router A, the virtual router master, fails, a selection process takes place to determine if virtual router backups B or C must take over. If Routers B and C are configured with the priorities of 101 and 100, respectively, Router B is elected to become virtual router master because it has the higher priority. If both have the same priority, the one with the higher IP address value is selected to become the virtual router master.

• Question 618:

  What is an OVF?

  A. a package that is similar to an IMG and that contains an OVA file used to build a virtual machine
  B. an alternative form of an ISO that Is used to install the base operating system of a virtual machine
  C. the third step in a P2V migration
  D. a package of files that is used to describe a virtual machine or virtual appliance
  D. a package of files that is used to describe a virtual machine or virtual appliance

• Question 619:

  SIMULATION

  Guidelines

  This is a lab item in which tasks will be performed on virtual devices.

  1. Refer to the Tasks tab to view the tasks for this lab item.

  2. Refer to the Topology tab to access the device console(s) and perform the tasks.

  3. Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.

  4. All necessary preconfigurations have been applied.

  5. Do not change the enable password or hostname for any device.

  6. Save your configurations to NVRAM before moving to the next item.

  7. Click Next at the bottom of the screen to submit this lab and move to the next question.

  8. When Next is clicked, the lab closes and cannot be reopened.

  Topology

  

  Tasks

  Configure OSPF on all three routers according to the topology diagram to achieve these goals:

  1. Enable OSPF on all interfaces using the network statement and match the network mask of each interface.

  2. Ensure that all networks are advertised between the routers.

  3. Ensure that all routers use OSPF process ID 1 and that the Lo0 interface is used for the router ID.

  4. Configure OSPF MD5 authentication on every physical interface running OSPF using key 1 and the password ccnp321.
