Cisco 350-401 Online Practice Questions and Exam Preparation

Cisco 350-401 Online Questions & Answers

• Question 1411:

  Refer to the exhibit.

  

  A network engineer must configure a WLAN on a Cisco IOS-XE controller to support corporate devices (using VLAN 30) and BYOD (using VLAN 40) on the same secure SSID. The security team has built an ISE deployment to be used for

  VLAN assignment and to restrict access based on policy and posture compliance.

  Given the existing WLAN configuration, which configuration change must be made?

  A. remove ip dhcp required
  B. Add aaa-override
  C. Remove nac
  D. Add mac-filtering default
  B. Add aaa-override

• Question 1412:

  How does the EIGRP metric differ from the OSPF metric?

  A. The EIGRP metric is calculated based on bandwidth only. The OSPF metric is calculated on delay only.
  B. The EIGRP metric is calculated based on delay only. The OSPF metric is calculated on bandwidth and delay.
  C. The EIGRP metric Is calculated based on bandwidth and delay. The OSPF metric is calculated on bandwidth only.
  D. The EIGRP metric Is calculated based on hop count and bandwidth. The OSPF metric is calculated on bandwidth and delay.
  C. The EIGRP metric Is calculated based on bandwidth and delay. The OSPF metric is calculated on bandwidth only.

  ---

  Explanation

  By default, EIGRP metric is calculated: metric = bandwidth + delay While OSPF is calculated by: OSPF metric = Reference bandwidth / Interface bandwidth in bps (Or Cisco uses 100Mbps (108) bandwidth as reference bandwidth. With this bandwidth, our equation would be: Cost = 108/interface bandwidth in bps)

• Question 1413:

  Refer to the exhibit.

  

  Clients are reporting an issue with the voice traffic from the branch site to the central site.

  What is the cause of this issue?

  A. There is a routing loop on the network
  B. There is a high delay on the WAN links
  C. Traffic is load-balancing over both links, causing packets to arrive out of order
  D. The voice traffic is using the link with less available bandwidth
  A. There is a routing loop on the network

  ---

  Explanation

  Looking at the Traceroute results, I see the same IP address repeated on each hop. This may be caused by repeated hops to the same IP address, causing packets to become stuck in a loop.

• Question 1414:

  Refer to the exhibit.

  

  An engineer must modify the access control list EGRESS to allow all IP traffic from subnet 10.1.10.0/24 to 10.1.2.0/24. The access control list is applied in the outbound direction on router interface GigabitEthernet 0/1.

  Which configuration command set will allow this traffic without disrupting existing traffic flows?

  

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

• Question 1415:

  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 1416:

  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 1417:

  DRAG DROP

  Drag and drop the characteristics from the left onto the infrastructure types on the right.

  Select and Place:

  

  

• Question 1418:

  Refer to the exhibit.

  

  External users require HTTP connectivity to an internal company web server that is listening on TCP port 8080.

  Which command set accomplishes this requirement?

  

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

• Question 1419:

  A network administrator wants to install new VoIP switches in a small network closet but is concerned about the current heat level of the room.

  Which of the following should the administrator take into consideration before installing the new equipment?

  A. The power load of the switches
  B. The humidity in the room
  C. The fire suppression system
  D. The direction of airflow within the switches
  D. The direction of airflow within the switches

• Question 1420:

  A. Configure channel-group 1 mode active on GVO and G1 1 of SW2.
  B. Configure twitchport trunk encapsulation dot1q on SW1 and SW2.
  C. Configure channel-group 1 mode active on Gl'O and GM of SW1 .
  D. Configure switchport mode dynamic desirable on SW1 and SW2
  C. Configure channel-group 1 mode active on Gl'O and GM of SW1 .
