Cisco CCIE Enterprise Wireless 350-401 Questions & Answers

• Question 961:

  An engineer must export the contents of the devices object in JSON format. Which statement must be used?

  

  A. json.repr(Devices)

  B. json.dumps(Devices)

  C. json.prints(Devices)

  D. json.loads(Devices)

  Correct Answer: B

• Question 962:

  Refer to the exhibit.

  

  What is the result when a switch that is running PVST+ is added to this network?

  A. DSW2 operates in Rapid PVST+ and the new switch operates in PVST+

  B. Both switches operate in the PVST+ mode

  C. Spanning tree is disabled automatically on the network

  D. Both switches operate in the Rapid PVST+ mode.

  Correct Answer: A

  From the output we see DSW2 is running in RSTP mode (in fact Rapid PVST+ mode as Cisco does not support RSTP alone). When a new switch running PVST+ mode is added to the topology, they keep running the old STP instances as RSTP (in fact Rapid PVST+) is compatible with PVST+.

• Question 963:

  When is the Design workflow used In Cisco DNA Center?

  A. in a greenfleld deployment, with no existing infrastructure

  B. in a greenfield or brownfield deployment, to wipe out existing data

  C. in a brownfield deployment, to modify configuration of existing devices in the network

  D. in a brownfield deployment, to provision and onboard new network devices

  Correct Answer: A

  "The Design area is where you create the structure and framework of your network, including the physical topology, network settings, and device type profiles that you can apply to devices throughout your network. Use the Design workflow if you do not already have an existing infrastructure. If you have an existing infrastructure, use the Discovery feature."

• Question 964:

  Refer to the exhibit

  

  The network administrator must be able to perform configuration changes when all the RADIUS servers are unreachable. Which configuration allows all commands to be authorized if the user has successfully authenticated?

  A. aaa authorization exec default group radius none B. aaa authentication login default group radius local none

  C. aaa authorization exec default group radius if-authenticated

  D. aaa authorization exec default group radius

  Correct Answer: C

  The keyword"if-authenticated" sayings that if we are authenticated we will immediately be dropped into exec (enable) mode.

• Question 965:

  Which statement about multicast RPs is true?

  A. RPs are required only when using protocol independent multicast dense mode.

  B. RPs are required for protocol independent multicast sparse mode and dense mode.

  C. By default, the RP is needed periodically to maintain sessions with sources and receivers

  D. By default, the RP is needed only to start new sessions with sources and receivers.

  Correct Answer: D

  A rendezvous point (RP) is required only in networks running Protocol Independent Multicast sparse mode (PIM-SM).

  By default, the RP is needed only to start new sessions with sources and receivers. Reference: https://www.cisco.com/c/en/us/td/docs/ios/solutions_docs/ip_multicast/White_papers /rps.html For your information, in PIM-SM, only network

  segments with active receivers that have explicitly requested multicast data will be forwarded the traffic. This method of delivering multicast data is in contrast to the PIM dense mode (PIM-DM) model. In PIM-DM, multicast traffic is initially

  flooded to all segments of the network. Routers that have no downstream neighbors or directly connected receivers prune back the unwanted traffic.

• Question 966:

  Which technology does VXLAN use to provide segmentation for Layer 2 and Layer 3 traffic?

  A. bridge domain

  B. VLAN

  C. VRF

  D. VNI

  Correct Answer: D

  VXLAN has a 24-bit VXLAN network identifier (VNI), which allows for up to 16 million (= 224) VXLAN segments to coexist within the same infrastructure. This surely solve the small number of traditional VLANs.

• Question 967:

  Refer to the exhibit.

  An engineer attempts to configure a router on a stick to route packets between Clients, Servers, and Printers; however, initial tests show that this configuration is not working. Which command set resolves this issue?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: C

  We must reconfigure the IP address after assigning or removing an interface to a VRF. Otherwise that interface does not have an IP address.

• Question 968:

  How do cloud deployments differ from on-prem deployments?

  A. Cloud deployments require longer implementation times than on-premises deployments

  B. Cloud deployments are more customizable than on-premises deployments.

  C. Cloud deployments require less frequent upgrades than on-premises deployments.

  D. Cloud deployments have lower upfront costs than on-premises deployments.

  Correct Answer: D

• Question 969:

  What does a northbound API accomplish?

  A. programmatic control of abstracted network resources through a centralized controller

  B. access to controlled network resources from a centralized node

  C. communication between SDN controllers and physical switches

  D. controlled access to switches from automated security applications

  Correct Answer: A

• Question 970:

  Refer to the exhibit.

  

  What is the result when a technician adds the monitor session 1 destination remote vlan 223 command?

  A. The RSPAN VLAN is replaced by VLAN 223.

  B. RSPAN traffic is sent to VLANs 222 and 223.

  C. An error is flagged for configuring two destinations.

  D. RSPAN traffic is split between VLANs 222 and 223.

  Correct Answer: A

  This is the result in a lab. switch-1(config)#do sh run | s monitor monitor session 1 source interface Gi1/0/2 rx monitor session 1 source interface Gi1/0/1 tx monitor session 1 source interface Po14 monitor session 1 destination remote vlan 222

  switch-1(config)#do sh monitor session 1 Session 1

  Type : Remote Source Session Source Ports : RX Only : Gi1/0/2 TX Only : Gi1/0/1 Both : Po14 Dest RSPAN VLAN : 222

  switch-1(config)#monitor session 1 destination remote vlan 223 switch-1(config)#do sh run | s monitor monitor session 1 source interface Gi1/0/2 rx monitor session 1 source interface Gi1/0/1 tx monitor session 1 source interface Po14 monitor session 1 destination remote vlan 223 switch-1(config)#do sh monitor session 1 Session 1

  Type : Remote Source Session Source Ports : RX Only : Gi1/0/2 TX Only : Gi1/0/1 Both : Po14 Dest RSPAN VLAN : 223
