Cisco 350-401 Online Questions & Answers

• Question 441:

  Which statement about a Cisco APIC controller versus a more traditional SDN controller is true?

  A. APIC does support a Southbound REST API
  B. APIC supports OpFlex as a Northbound protocol
  C. APIC uses a policy agent to translate policies into instructions
  D. APIC uses an imperative model
  C. APIC uses a policy agent to translate policies into instructions

  ---

  Explanation

  The southbound protocol used by APIC is OpFlex that is pushed by Cisco as the protocol for policy enablement across physical and virtual switches. Southbound interfaces are implemented with some called Service Abstraction Layer (SAL), which talks to the network elements via SNMP and CLI.

  Note: Cisco OpFlex is a southbound protocol in a software-defined network (SDN).

• Question 445:

  What happens when a FlexConnect AP changes to standalone mode?

  A. All controller-dependent activities stop working except the DFS.
  B. All client roaming continues to work
  C. Only clients on central switching WLANs stay connected.
  D. All clients on an WLANs are disconnected
  A. All controller-dependent activities stop working except the DFS.

  ---

  Explanation

  When a FlexConnect access point enters standalone mode, it disassociates all clients that are on centrally switched WLANs. [ not all clients, locally switched WLAN clients stay connected]

  Controller-dependent activities, such as network access control (NAC) and web authentication (guest access), are disabled, and the access point does not send any intrusion detection system (IDS) reports to the controller.

  Most radio resource management (RRM) features (such as neighbor discovery; noise, interference, load, and coverage measurements; use of the neighbor list; and rogue containment and detection) are disabled. However, a FlexConnect access point supports dynamic frequency selection in standalone mode.

• Question 446:

  An engineer must configure HSRP for VLAN 1200 on SW1. The second switch is configured by using the last usable IP address in the network as the virtual IP. Which command set accomplishes litis task?

  A. SW1(config)# interface vlan 1200SW1(config-if)# ip address 172.12.0.254 255.255.255.0SW1(config-if)# standby version 2SW1(config-if)# standby 1200 ip 172.12.0.2SW1(conflg-it)# standby 1200 preempt
  B. SW1(config)# interface vlan 1200SW1(config-if)# ip address 172.12.0.2 255.255.255.0SW1(config-if)# standby version 2SW1(config-if)# standby 1200 ip 172.12.0.254SW1(conflg-it)# standby 1200 preempt
  C. SW1(config)# interface vlan 1200SW1(config-if)# ip address 172.12.0.2 255.255.255.0SW1(config-if)# standby 1200 ip 172.12.0.254SW1(config-if)# standby 1200 timers 5 15SW1(conflg-it)# standby 1200 preempt
  D. SW1(config)# interface vlan 1200SW1(config-if)# ip address 172.12.0.1 255.255.255.0SW1(config-if)# standby 1200 ip 172.12.0.254SW1(config-if)# standby 1200 timers 5 15SW1(conflg-it)# standby 1200 preempt
  B. SW1(config)# interface vlan 1200SW1(config-if)# ip address 172.12.0.2 255.255.255.0SW1(config-if)# standby version 2SW1(config-if)# standby 1200 ip 172.12.0.254SW1(conflg-it)# standby 1200 preempt

• Question 447:

  What is the role of the vsmart controller in a Cisco SD-WAN environment?

  A. IT performs authentication and authorization
  B. It manages the control plane.
  C. It is the centralized network management system.
  D. It manages the data plane.
  B. It manages the control plane.

  ---

  Explanation

  + Control plane (vSmart) builds and maintains the network topology and make decisions on the traffic flows. The vSmart controller disseminates control plane information between WAN Edge devices, implements control plane policies and distributes data plane policies to network devices for enforcement.

• Question 450:

  A network monitoring system uses SNMP polling to record the statistics of router interfaces The SNMP queries work as expected until an engineer installs a new interface and reloads the router After this action, all SNMP queries for the router fail What is the cause of this issue?

  A. The SNMP community is configured incorrectly
  B. The SNMP interface index changed after reboot.
  C. The SNMP server traps are disabled for the interface index
  D. The SNMP server traps are disabled for the link state.
  B. The SNMP interface index changed after reboot.

  Explanation

  In order to tell IOS to keep ifindex value unchanged even after reboot, use the "snmp-server ifindex persist" command
