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?
  1. Differentiated Services Code Point (DSCP) settings
  2. Frame-relay Traffic Shaping (FRTS) settings
  3. Class-to-Service (CoS) settings
  4. Type-of-service (ToS) settings
  5. Forward Explicit Congestion Notification (FECN) of Backward Explicit Congestion Notification (BECN) settings
Correct answer: E
Question 2
Which of the following statements is true about the port mirroring on Huawei devices?
  1. Huawei devices support port mirroring on the control traffic sent to the CPU
  2. Huawei devices support flow-based port mirroring. The mirrored traffic can be copied onto multiple observing ports
  3. Traffic in the RSPAN is transmitted to observing ports in multicast mode
  4. When the observing port becomes congested, mirrored packets cannot be discarded because these packets have higher priority than service traffic
Correct answer: A
Question 3
Spanning Tree Protocol calculates path cost based on which of the following?
  1. Interface bandwidth
  2. Interface delay
  3. Hop count
  4. Interface bandwidth and delay
  5. Bridge priority
Correct answer: A
Question 4
  
Based on the preceding networking and configurations, which of the following statements is true? 
  
  1. Route flapping occurs
  2. RTB and RTC cannot establish a neighbor relationship
  3. RTA and RTB cannot establish a neighbor relationship
  4. A neighbor relationship can be established; all network segments are reachable
Correct answer: D
Question 5
When a router is building a routing table from different routing protocols, which of the following will determine the routes to be installed in the routing table?
  1. The fastest routing process
  2. uniqueness
  3. Higher preference value
  4. The route with the largest next-hop address
  5. Low Router ID
Correct answer: C
Question 6
Routers R1 and R2 are configured for BGP. Both routers are in AS 65234. Routes from Router R2 are in the BGP table on Router R1, but not in the IP routing table. What could be the cause of this problem?
  1. Synchronization is off
  2. BGP multi-hop is disabled on Router R1
  3. The next-hop of these routes can not reach by router R1
  4. The BGP peers are down
Correct answer: C
Question 7
Which types of prefixes will a router running BGP most likely advertise to an IBGP peer, assuming it is not configured as a route reflector?
  1. Prefixes received from EBGP peers and prefixes received from route reflectors
  2. All prefixes in its routing table
  3. Prefixes received from EBGP peers and prefixes locally originated via network statements or imported
  4. Prefixes received from other IBGP peers, prefixes received from EBGP peers, and prefixes imported to BGP
  5. Prefixes received from other IBGP peers and prefixes received from router reflectors
  6. Prefixes received from any other BGP peer and prefixes locally originated via network statements or imported
Correct answer: C
Question 8
In a data communication session between two hosts, the session layer in the OSI model generally communicates with what other layer of the OSI model?
  1. The physical layer of the peer
  2. The peer’s presentation layer
  3. The peer’s session layer
  4. The peer’s application layer
  5. The data link layer of the peer
Correct answer: C
Question 9
If a router receives a BGP route carrying the no-export community attribute, which of the following actions does the router take?
  1. Does not advertise the route to other BGP routers
  2. Discards the route directly
  3. Advertises the route to IBGP peers only
  4. Advertises the route normally, but does not use it to forward data
Correct answer: C
Question 10
As shown in the following figure, the neighbor relationship between R1 and R2 has just been established. Which of the following statements is true about the database synchronization process between R1 and R2? 
  
  1. The packet sent from R1 and R2 is a PSNP packet
  2. The packet sent from R1 and R2 is a Hello packet
  3. The packet sent from R1 and R2 is a CSNP packet
  4. The packet sent from R1 and R2 is a LSP packet
Correct answer: A
