Cisco CCIE Enterprise Wireless 350-401 Questions & Answers

• Question 891:

  An engineer is implementing MPLS OAM to monitor traffic within the MPLS domain. Which action must the engineer perform to prevent from being forwarded beyond the service provider domain when the LSP is down?

  A. Disable IP redirects only on outbound interfaces.

  B. Implement the destination address for the LSP echo request packet in the 127.x.y.z/8 network.

  C. Disable IP redirects on all ingress interfaces.

  D. Configure a private IP address as the destination address of the headend router of Cisco MPLS TE.

  Correct Answer: C

• Question 892:

  A network engineer must configure a router to send logging messages to a syslog server based on these requirements:

  1.

  uses syslog IP address: 10.10.10.1

  2.

  uses a reliable protocol

  3.

  must not use any well-known TCP/UDP ports Which configuration must be used?

  A. logging host 10.10.10.1 transport tcp port 1024

  B. logging origin-id 10.10.10.1

  C. logging host 10.10.10.1 transport udp port 1023

  D. logging host 10.10.10.1 transport udp port 1024

  Correct Answer: A

• Question 893:

  Refer to the exhibit.

  

  An engineer must prevent the R6 loopback from getting into Area 2 and Area 3 from Area 0 Which action must the engineer take?

  A. Apply a fitter list inbound on R2 and R9

  B. Apply a filter list outbound on R3 and R7

  C. Apply a filter list outbound on R7 only.

  D. Apply a filter list inbound on R3 and R7

  Correct Answer: B

  This question asks to prevent route advertised into Area 2 and Area 3 only. It does not ask to prevent route advertised into Area 0 so applying a filter list outbound on R3 and R7 would best fit the requirement.

• Question 894:

  What is one difference between EIGRP and OSPF?

  A. OSPF is a Cisco proprietary protocol, and EIGRP is an IETF open standard protocol.

  B. OSPF uses the DUAL distance vector algorithm, and EIGRP uses the Dijkstra link-state algorithm

  C. EIGRP uses the variance command lot unequal cost load balancing, and OSPF supports unequal cost balancing by default.

  D. EIGRP uses the DUAL distance vector algorithm, and OSPF uses the Dijkstra link-state algorithm

  Correct Answer: D

  EIGRP is based on DUAL (Diffusing Update Algorithm) while OSPF uses Dijkstra's Shortest Path Algorithm with the major difference in how they calculate the shortest routing path. OSPF has capability to calculate the best shortest path to each reachable subnet/network using an algorithm called SFP (Shortest Path First) also known as Dijkstra algorithm. "Neighbor Table" that contain all discovered OSPF neighbour with whom routing information will be interchanged.

• Question 895:

  Refer to the exhibit. What step resolves the authentication issue?

  

  A. use basic authentication

  B. change the port to 12446

  C. target 192 168 100 82 in the URI

  D. restart the vsmart host

  Correct Answer: C

  He first figure is the output of the "show control connections" command. From this figure we learned that the 192.168.100.82 so we need to connect to this IP address (not 192.168.100.80).

• Question 896:

  Which LISP device is responsible for publishing EID-to-RLOC mappings for a site?

  A. ETR

  B. MS

  C. ITR

  D. MR

  Correct Answer: A

  An Egress Tunnel Router (ETR) connects a site to the LISP-capable part of a core network (such as the Internet), publishes EID-to-RLOC mappings for the site, responds to Map-Request messages, and decapsulates and delivers LISP-encapsulated user data to end systems at the site.

• Question 897:

  What is required for intercontroller Layer 3 roaming?

  A. Mobility groups are established between wireless controllers.

  B. The management VLAN is present as a dynamic VLAN on the second WLC.

  C. WLCs use separate DHCP servers.

  D. WLCs have the same IP addresses configured on their interfaces.

  Correct Answer: D

• Question 898:

  What are two common sources of interference for Wi-Fi networks? (Choose two.)

  A. LED lights

  B. radar

  C. fire alarm

  D. conventional oven

  E. rogue AP

  Correct Answer: BE

• Question 899:

  What is a benefit of Type 1 hypervisors?

  A. Administrators are able to load portable virtual machine packages in OVA or QCOW2 formats.

  B. Network engineers are able to create virtual networks o interconnect virtual machines in Layer 2 topologies

  C. Operators are able to leverage orchestrators to manage workloads that run on multiple Type 1 hypervisors

  D. Storage engineers are able to leverage VMDK files to provide storage to virtual machine.

  Correct Answer: B

• Question 900:

  Which method does Cisco DNA Center use to allow management of non-Cisco devices through southbound protocols?

  A. It creates device packs through the use of an SDK

  B. It uses an API call to interrogate the devices and register the returned data.

  C. It obtains MIBs from each vendor that details the APIs available.

  D. It imports available APIs for the non-Cisco device in a CSV format.

  Correct Answer: A

  Cisco DNA Center allows customers to manage their non-Cisco devices through the use of a Software Development Kit (SDK) that can be used to create Device Packages for third-party devices.
