Cisco 350-401 Online Questions & Answers

• Question 761:

  Refer to the exhibit. R1 is able to ping the R3 fa0/1 interface.

  Why do the extended pings fail?

  

  A. The maximum packet size accepted by the command is 1476 bytes.
  B. R3 is missing a return route to 10.99.69.0/30
  C. R2 and R3 do not have an OSPF adjacency
  D. The DF bit has been set
  D. The DF bit has been set

  ---

  Explanation

  If the DF bit is set, routers cannot fragment packets. From the output below, we learn that the maximum MTU of R2 is 1492 bytes while we sent ping with 1500 bytes.

  Therefore these ICMP packets were dropped.

  Note: Record option displays the address(es) of the hops (up to nine) the packet goes through.

• Question 762:

  Refer to the exhibit.

  

  What is the outcome of applying the service policy set-dscp-63 to switch port Gig0/0/0?

  A. DSCP 1 marked traffic will be re-marked to 63, and all other DSCP values will be honored.
  B. DSCP 1 marked traffic will be ignored, and DSCP 63 marked traffic will be honored.
  C. None. The service-policy configuration must be applied in the outbound direction.
  D. DSCP 1 marked traffic will be re-marked to 63, and all other DSCP values will be ignored.
  A. DSCP 1 marked traffic will be re-marked to 63, and all other DSCP values will be honored.

  ---

  Explanation

  The correct answer is A. DSCP 1 marked traffic will be re-marked to 63, and all other DSCP values will be honored.

  The exhibit shows this configuration:

  class-map match-any dscp-1

  match ip dscp 1

  policy-map set-dscp-63

  class dscp-1

  set dscp 63

  interface GigabitEthernet0/0/0

  mls qos trust dscp

  service-policy input set-dscp-63

  The class map matches packets with DSCP value 1:

  match ip dscp 1

  The policy map changes the DSCP marking of those matched packets to 63:

  set dscp 63

  The policy is applied in the input direction:

  service-policy input set-dscp-63

  The interface is also configured to trust DSCP:

  mls qos trust dscp

  This means incoming packets keep their DSCP markings unless a QoS policy explicitly changes them. Since the policy only matches DSCP 1, only DSCP 1 traffic is re-marked to 63. Traffic with other DSCP values is not matched by the policy and remains trusted and unchanged.

  Option B is incorrect because DSCP 1 traffic is not ignored; it is matched and re-marked.

  Option C is incorrect because QoS marking policies can be applied in the input direction.

  Option D is incorrect because other DSCP values are not ignored; they are trusted.

• Question 763:

  Which statement about a fabric access point is true?

  A. It is in local mode an must be connected directly to the fabric border node.
  B. It is in FlexConnect mode and must be connected directly to the fabric border node.
  C. It is in local mode an must connected directly to the fabric edge switch.
  D. It is in FlexConnect mode and must be connected directly to the fabric edge switch.
  C. It is in local mode an must connected directly to the fabric edge switch.

  Explanation

  Fabric mode APs continue to support the same wireless media services that traditional APs support; apply AVC, quality of service (QoS), and other wireless policies; and establish the CAPWAP control plane to the fabric WLC. Fabric APs join as local-mode APs and must be directly connected to the fabric edge node switch to enable fabric registration events, including RLOC assignment via the fabric WLC. The fabric edge nodes use CDP to recognize APs as special wired hosts, applying special port configurations and assigning the APs to a unique overlay network within a common EID space across a fabric. The assignment allows management simplification by using a single subnet to cover the AP infrastructure at a fabric site.

• Question 764:

  Which device, in a LISP routing architecture, receives and de-encapsulates LISP traffic for endpoints within a LISP-capable site?

  A. MR
  B. ETR
  C. OMS
  D. ITR
  B. ETR

• Question 765:

  What gives priority on an egress interface, for database traffic that connected on an ingress interface, without changing the CoS value?

  A. QoS group
  B. policy map
  C. CoS map
  D. class map
  B. policy map

• Question 766:

  What is a characteristic of a Type 2 hypervisor?

  A. quick deployment
  B. ideal for data center
  C. complicated deployment
  D. referred to as bare-metal
  A. quick deployment

• Question 767:

  DRAG DROP

  Drag and drop the characteristics from the left onto the deployment model on the right.

  Select and Place:

  

  

• Question 768:

  An engineer must configure a router to allow users to run spathic configuration commands by validating the user against the router database.

  Which configuration must be applied?

  A. aaa authentication network default local
  B. aaa authentication exec default local
  C. aaa authorization exec default local
  D. aaa authorization network default local
  C. aaa authorization exec default local

• Question 769:

  Which Python code snippet must be added to the script to store the changed interface configuration to a local JSON-formatted file?

  

  

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

  ---

  Explanation

  1 - 'response' type is (class Response). 2 - 'UpdateConfig' converted 'response' to a String, so it's a String. 3 - When using write() the passed argument must be a String.

  NOT C, json.dump(ARG1, ARG2) method takes a python dictionary NOT a String, and convert it as a JSON file.

• Question 770:

  Which JSON script is properly formatted?

  

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