Cisco 350-401 Online Questions & Answers

• Question 671:

  Which two functions is an edge node responsible for? (Choose two.)

  A. provides multiple entry and exit points for fabric traffic
  B. provides the default exit point for fabric traffic
  C. provides the default entry point for fabric traffic
  D. provides a host database that maps endpoint IDs to a current location
  E. authenticates endpoints
  C. provides the default entry point for fabric traffic
  E. authenticates endpoints

• Question 672:

  How does the RIB differ from the FIB?

  A. The RIB is used to create network topologies and routing tables. The FIB is a list of routes to particular network destinations.
  B. The FIB includes many routes a single destination. The RIB is the best route to a single destination.
  C. The RIB includes many routes to the same destination prefix. The FIB contains only the best route
  D. The FIB maintains network topologies and routing tables. The RIB is a Iist of routes to particular network destinations.
  C. The RIB includes many routes to the same destination prefix. The FIB contains only the best route

  ---

  Explanation

  RIBs maintain the network topologies and routing tables for each protocol. This would include many routes going to the same destination prefix. FIBs are the best route from the possibly many protocols in the RIBs pushed down to fast forwarding lookup memory for the best path(s).

• Question 673:

  Refer to the exhibit.

  

  What does the Python code accomplish?

  A. It configures interface e1/32 to be in an admin down state
  B. It generates a status code of 403 because the type is incorrect.
  C. It configures interface e1/32 to be in an err-disable state.
  D. It returns data in JSON-RPC format.
  A. It configures interface e1/32 to be in an admin down state

• Question 674:

  Refer to the exhibit. Communication between London and New York is down

  Which command set must be applied to resolve this issue?

  

  

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

• Question 675:

  What is a characteristic of an AP operating in FlexConnect Mode?

  A. All traffic traverses the WLC to ensure policy enforcement on client traffic
  B. Forwarding continues when the AP loses connectivity to the WLC
  C. APs connect in a mesh topology and elect a root AP
  D. FlexConnect enables an AP to connect to multiple WLCs
  B. Forwarding continues when the AP loses connectivity to the WLC

  ---

  Explanation

  The AP can locally switch traffic between a VLAN and SSID when the CAPWAP tunnel to the WLC is down.

• Question 676:

  Witch two actions provide controlled Layer 2 network connectivity between virtual machines running on the same hypervisor? (Choose two.)

  A. Use a single trunk link to an external Layer2 switch.
  B. Use a virtual switch provided by the hypervisor.
  C. Use a virtual switch running as a separate virtual machine.
  D. Use a single routed link to an external router on stick.
  E. Use VXLAN fabric after installing VXLAN tunneling drivers on the virtual machines.
  B. Use a virtual switch provided by the hypervisor.
  C. Use a virtual switch running as a separate virtual machine.

• Question 677:

  What is the differences between TCAM and the MAC address table?

  A. The MAC address table is contained in CAM. ACL and QoS information is stored in TCAM.
  B. The MAC address table supports partial matches. TCAM requires an exact match
  C. Router prefix lookups happens in CAM. MAC address table lookups happen in TCAM.
  D. TCAM is used to make Layer 2 forwarding decisions CAM is used to build routing tables
  A. The MAC address table is contained in CAM. ACL and QoS information is stored in TCAM.

  Explanation

  https://community.cisco.com/t5/networking-documents/cam-content-addressable-memory-vs-tcam-ternary-content/ta-p/3107938

  When using Ternary Content Addressable Memory (TCAM) inside routers it's used for faster address lookup that enables fast routing. In switches Content Addressable Memory (CAM) is used for building and lookup of mac address table that enables L2 forwarding decisions. Besides Longest-Prefix Matching, TCAM in today's routers and multilayer Switch devices are used to store ACL, QoS and other things from upper-layer processing.

• Question 678:

  Which feature Is used to propagate ARP broadcast, and link-local frames across a Cisco SDAccess fabric to address connectivity needs for silent hosts that require reception of traffic to start communicating?

  A. Native Fabric Multicast
  B. Layer 2 Flooding
  C. SOA Transit
  D. Multisite Fabric
  B. Layer 2 Flooding

  ---

  Explanation

  Layer2 FloodingCisco SD-Access fabric provides many optimizations to improve unicast traffic flow, and to reduce the unnecessary flooding of data such as broadcasts. But, for some traffic and applications, it may be desirable to enable broadcast forwarding within the fabric.

  By default, this is disabled in the Cisco SD-Access architecture. If broadcast, Link local multicast and Arp flooding is required, it must be specifically enabled on a per-subnet basis using Layer 2 flooding feature. Layer 2 flooding can be used to forward broadcasts for certain traffic and application types which may require leveraging of Layer 2 connectivity, such as silent hosts, card readers, door locks, etc.

• Question 679:

  What is one characteristic of VXLAN?

  A. It supports a maximum of 4096 VLANs.
  B. It supports multitenant segments.
  C. It uses STP to prevent loops in the underlay network.
  D. It uses the Layer 2 header to transfer packets through the network underlay.
  B. It supports multitenant segments.

• Question 680:

  When should the MAC authentication bypass feature be used on a switch port?

  A. when authentication is required, but the attached host does not support 802.1X
  B. when the attached host supports limited 802.1X
  C. when authentication should be bypassed for select hosts based on their MAC address
  D. when the attached host supports 802.1X and must authenticate itself based on its MAC address instead of user credentials
  A. when authentication is required, but the attached host does not support 802.1X
