Demo Questions

Question 1
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?
  1. 802.3AF
  2. 802.1D
  3. 802.3
  4. 802.3X
  5. 802.1U
Correct answer: D
Question 2
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 3
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?
  1. Triggered updates should be configured on the headquarters router, to directly forward routing updates between the two remote sites
  2. The headquarters site router has split-horizon enabled on the frame-relay interface
  3. Neighbor statements are not configured on the two remote sites, pointing to all other sites
  4. The frame-relay IP to DLCI mappings are incorrectly configured
  5. RIP cannot propagate routing updates over a partial mesh frame-relay configuration, so another routing protocol should be selected
Correct answer: B
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
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 6
What is the destination IP address of routing update packets sent by RIPv2?
  1. 255.255.255.255
  2. 224.0.0.1
  3. 224.0.0.5
  4. 224.0.0.9
  5. 224.0.0.10
Correct answer: D
Question 7
The LS Sequence Number field is used to detect expired and duplicate LSAs. This field is a signed 32-bit integer and therefore the minimum LS Sequence Number is 0x800000000.
  1. FALSE
  2. TRUE
Correct answer: A
Question 8
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 9
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 10
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
