Demo Questions

Question 1
Router HW1 is seeing a large number of Discard Eligible (DE) frames. In Frame-relay, as part of the Congestion-Control Mechanism, the DE bit works in conjunction with which of the following mechanisms?

  • A: Differentiated Services Code Point (DSCP) settings
  • B: Frame-relay Traffic Shaping (FRTS) settings
  • C: Class-to-Service (CoS) settings
  • D: Type-of-service (ToS) settings
  • E: Forward Explicit Congestion Notification (FECN) of Backward Explicit Congestion Notification (BECN) settings



Question 2
Which parameter will not be received from the root bridge by a non-root bridge running 802.1D STP?

  • A: Forward delay
  • B: Hello time
  • C: Root cost
  • D: Hold time
  • E: Max Age



Question 3
Which of the following are used in Ethernet networks? (Multiple Choice)

  • A: 802.5 encapsulated frames
  • B: 802.3 encapsulated frames
  • C: CSMA/CD for media access
  • D: Non Canonical format MAC addresses
  • E: Canonical format MAC addresses



Question 4
Which of the following statements is true about the port mirroring on Huawei devices?

  • A: Huawei devices support port mirroring on the control traffic sent to the CPU
  • B: Huawei devices support flow-based port mirroring. The mirrored traffic can be copied onto multiple observing ports
  • C: Traffic in the RSPAN is transmitted to observing ports in multicast mode
  • D: When the observing port becomes congested, mirrored packets cannot be discarded because these packets have higher priority than service traffic



Question 5
If a Gigabit Ethernet port receive buffer becomes full on a LAN switch, what protocol can be used to request that the remote port delay sending frames for a specified time?

  • A: 802.3AF
  • B: 802.1D
  • C: 802.3
  • D: 802.3X
  • E: 802.1U



Question 6
When receives or transmits data frames on an access port, what will the switch do?

  • A: Switch will send tagged frames belong to a specified vlan
  • B: When received a tagged frame from an access port. Switch may forward it vlan
  • C: Switch will learn the MAC-address only on access port
  • D: Switch only receives untagged frames from access port and drop all tagged frames



Question 7
Spanning Tree Protocol calculates path cost based on which of the following?

  • A: Interface bandwidth
  • B: Interface delay
  • C: Hop count
  • D: Interface bandwidth and delay
  • E: Bridge priority



Question 8
On router HW1, you want to view the status of a frame relay connection. Which "display" commands will show the status of a Frame-Relay PVC? (Multiple choice)

  • A: display frame relay interface
  • B: display frame relay pvc
  • C: display fr lmi-info 
  • D: display fr map-info interface Serial 0/0/0
  • E: display fr interface Serial 0/0/0
  • F: display fr inarp-info



Question 9
HW has a Frame Relay network with two sites (a headquarters site and a remote site) connected by a single PVC. RIP version 2 is running in the network. A new remote site is added and HW has ordered a second PVC between this site and the headquarters site. All Frame Relay interface IP addresses are in a single subnet. The customer configured Frame Relay DLCI mappings and can successfully ping from the new remote to the headquarters site as well as to the other remote site. However, the new router does not have a route in its route table to the other remote site's LAN, and cannot ping the LAN interface or any hosts on that LAN. What is most likely causing the problem?

  • A: Triggered updates should be configured on the headquarters router, to directly forward routing updates between the two remote sites
  • B: The headquarters site router has split-horizon enabled on the frame-relay interface
  • C: Neighbor statements are not configured on the two remote sites, pointing to all other sites
  • D: The frame-relay IP to DLCI mappings are incorrectly configured
  • E: RIP cannot propagate routing updates over a partial mesh frame-relay configuration, so another routing protocol should be selected



Question 10

Based on the preceding networking and configurations, which of the following statements is true?



  • A: Route flapping occurs
  • B: RTB and RTC cannot establish a neighbor relationship
  • C: RTA and RTB cannot establish a neighbor relationship
  • D: A neighbor relationship can be established; all network segments are reachable
