Cisco 350-401 Online Questions & Answers

• Question 791:

  What is the function of a control-plane node in a Cisco SD-Access solution?

  A. to run a mapping system that manages endpoint to network device relationships
  B. to implement policies and communicate with networks outside the fabric
  C. to connect external Layer 3 networks to the SD Access fabric.
  D. to connect APs and wireless endpoints to the SD-Access fabric
  A. to run a mapping system that manages endpoint to network device relationships

• Question 792:

  While configuring an IOS router for HSRP with a virtual IP of 10.1.1.1, an engineer sees this log message.

  Jan 1 12:12:12.111 : %HSRP-4-DIFFVIP1: GigabitEthernet0/0 Grp 1 active routers virtual IP address 10.1.1.1 is different to the locally configured address 10.1.1.25

  Which configuration change must the engineer make?

  A. Change the HSRP group configuration on the remote router to 1.
  B. Change the HSRP group configuration on the local router to 1.
  C. Change the HSRP virtual address on the remote router to 10.1.1.1.
  D. Change the HSRP virtual address on the local router to 10.1.1.1.
  D. Change the HSRP virtual address on the local router to 10.1.1.1.

  ---

  Explanation

  Syslog points to local router having VIP ip 10.1.1.25, and remote router in g0/0 interface having 10.1.1.1. We want latter to all routers in HSRP so we need to configure local router, hence B.

  "is different to the locally configured..."

• Question 793:

  How does the Cisco SD-Access control plane simplify traditional routing environments?

  A. Routing adjacencies are no longer required.
  B. Full routing tables are shared and ensure that all routers know all paths within the underlay fabric and overlay.
  C. Separation of EID and RLOC reduces the size of routing tables.
  D. Routers query all routes to the map server.
  C. Separation of EID and RLOC reduces the size of routing tables.

• Question 794:

  At which plane does vBond operate in Cisco SD-WAN solutions?

  A. control plane
  B. data plane
  C. orchestration plane
  D. management plane
  C. orchestration plane

• Question 795:

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 796:

  Refer to the exhibit.

  A. mandatory
  B. association-comeback
  C. SA teardown protection
  D. saquery-retry-time
  E. enable
  F. comeback-time
  A. mandatory

• Question 797:

  What is used to measure the total output energy of a Wi-Fi device?

  A. dBi
  B. EIRP
  C. mW
  D. dBm
  C. mW

  ---

  Explanation

  Output power is measured in mW (milliwatts). answer 'dBi' milliwatt is equal to one thousandth (10-3) of a watt.

• Question 798:

  What is one role of an AP join profile on a Cisco wireless network?

  A. To allocate IP addresses to APs.
  B. To provide the settings and credentials that allow APs to authenticate to the network.
  C. To allocate network resources dynamically based on demand.
  D. To manage the radio frequency settings in different areas.
  B. To provide the settings and credentials that allow APs to authenticate to the network.

• Question 799:

  Which method does FastLocate use to collect location-based information?

  A. RFID
  B. client probing
  C. beacons
  D. data packets
  B. client probing

• Question 800:

  What mechanism does PIM use to forward multicast traffic?

  A. PIM sparse mode uses a pull model to deliver multicast traffic.
  B. PIM dense mode uses a pull model to deliver multicast traffic.
  C. PIM sparse mode uses receivers to register with the RP.
  D. PIM sparse mode uses a flood and prune model to deliver multicast traffic.
  A. PIM sparse mode uses a pull model to deliver multicast traffic.

  ---

  Explanation

  PIM dense mode (PIM-DM) uses a push model to flood multicast traffic to every corner of the network. This push model is a brute-force method of delivering data to the receivers. This method would be efficient in certain deployments in which there are active receivers on every subnet in the network. PIM-DM initially floods multicast traffic throughout the network. Routers that have no downstream neighbors prune the unwanted traffic. This process repeats every 3 minutes. PIM Sparse Mode (PIM-SM) uses a pull model to deliver multicast traffic. Only network segments with active receivers that have explicitly requested the data receive the traffic. PIM-SM distributes information about active sources by forwarding data packets on the shared tree. Because PIM-SM uses shared trees (at least initially), it requires the use of an RP. The RP must be administratively configured in the network. Answer C seems to be correct but it is not, PIM spare mode uses sources (not receivers) to register with the RP. Sources register with the RP, and then data is forwarded down the shared tree to the receivers.
