Cisco 350-401 Online Questions & Answers

• Question 921:

  Which of the following are valid statements when configuring Nonstop Forwarding (NSF) with Stateful Switchover (SSO) on a Cisco device? (Choose two.)

  A. supports multicast routing protocols
  B. Supports IPv4 and IPv6
  C. Nonstop Forwarding requires SSO to also be configured
  D. HSRP is not supported with NSF/SSO
  E. Improper implementation of NSF/SSO can result in routing loops
  C. Nonstop Forwarding requires SSO to also be configured
  D. HSRP is not supported with NSF/SSO

  ---

  Explanation

  NSF capability is supported for IPv4 routing protocols only. NSF capability is not supported for IPv6 routing protocols.

  NSF does not support IP Multicast Routing, as it is not SSO-aware.

  You must configure SSO in order to use NSF with any supported protocol.

  The Hot Standby Routing Protocol (HSRP) is not supported with NSF SSO. Do not use HSRP with NSF SSO.

• Question 922:

  In a Cisco SD-Access network architecture, which access layer cabling design is optimal for the underlay network?

  A. Switches are cross-linked at the same layer and have a single connection to each upstream distribution device.
  B. Switches are connected to each upstream distribution and core device.
  C. Switches are connected to each upstream distribution device.
  D. Switches are cross-linked to devices at the same layer and at the upstream and downstream devices.
  C. Switches are connected to each upstream distribution device.

• Question 924:

• Question 925:

  What is the responsibility of a secondary WLC?

  A. It shares the traffic load of the LAPs with the primary controller.
  B. It avoids congestion on the primary controller by sharing the registration load on the LAPs.
  C. It registers the LAPs if the primary controller fails.
  D. It enables Layer 2 and Layer 3 roaming between Itself and the primary controller.
  C. It registers the LAPs if the primary controller fails.

  ---

  Explanation

  When the primary controller (WLC-1) goes down, the APs automatically get registered with the secondary controller (WLC-2). The APs register back to the primary controller when the primary controller comes back on line.

• Question 926:

  Which standard access control entry permits from odd-numbered hosts in the 10.0.0.0/24 subnet?

  A. Permit 10.0.0.0.0.0.0.1
  B. Permit 10.0.0.1.0.0.0.0
  C. Permit 10.0.0.1.0.0.0.254
  D. Permit 10.0.0.0.255.255.255.254
  C. Permit 10.0.0.1.0.0.0.254

  ---

  Explanation

  Remember, for the wildcard mask, 1s are I DON'T CARE, and 0s are I CARE. So now let's analyze a simple ACL: access-list 1 permit 172.23.16.0 0.0.15.255

  Two first octets are all 0's meaning that we care about the network 172.23.x.x. The third octet of the wildcard mask, 15 (0000 1111 in binary), means that we care about first 4 bits but don't care about last 4 bits so we allow the third octet in the form of 0001xxxx (minimum:00010000 = 16; maximum: 0001111 = 31).

  

  The fourth octet is 255 (all 1 bits) that means I don't care. Therefore network 172.23.16.0 0.0.15.255 ranges from 172.23.16.0 to 172.23.31.255. Now let's consider the wildcard mask of 0.0.0.254 (four octet: 254 = 1111 1110) which means we only care the last bit. Therefore if the last bit of the IP address is a "1" (0000 0001) then only odd numbers are allowed. If the last bit of the IP address is a "0" (0000 0000) then only even numbers are allowed.

  Note: In binary, odd numbers are always end with a "1" while even numbers are always end with a "0".

  Therefore in this question, only the statement "permit 10.0.0.1 0.0.0.254" will allow all oddnumbered hosts in the 10.0.0.0/24 subnet.

• Question 927:

  What are two device roles in the Cisco SD-Access fabric? (Choose two.)

  A. access switch
  B. vBond controller
  C. edge node
  D. core switch
  E. border node
  C. edge node
  E. border node

• Question 928:

  Users have reported an issue connecting to a server over the network. A workstation was recently added to the network and configured with a shared USB printer.

  Which of the following is most likely causing the issue?

  A. The switch is oversubscribed and cannot handle the additional throughput.
  B. The printer is tying up the server with DHCP discover messages.
  C. The web server's back end was designed for only single-threaded applications.
  D. The workstation was configured with a static IP that is the same as the server.
  D. The workstation was configured with a static IP that is the same as the server.

• Question 929:

  What is the role of a LISP map server?

  A. It receives information from ETRs that map EIDs to RLOCs
  B. It transmits requests for EID-to-RLOC resolution
  C. It transmits information from ETRs that map EIDs to RLOCs
  D. It responds to requests for EID-to-RLOC resolution.
  A. It receives information from ETRs that map EIDs to RLOCs

• Question 930:

  Which tag defines the properties to be applied to each specific WLAN?

  A. RF tag
  B. policy tag
  C. AP tag
  D. site tag
  B. policy tag

  ---

  Explanation

  In the context of Cisco Catalyst 9800 Series Wireless Controllers, a policy tag is used to define the properties that will be applied to each specific WLAN. The policy tag maps the WLAN profile to the policy profile, which in turn defines the wireless characteristics of the WLAN and the network policies and switching policies for the client 2.
