Q1. - (Topic 3)
What command is used to verify the DLCI destination address in a Frame Relay static configuration?
A. show frame-relay pvc
B. show frame-relay lmi
C. show frame-relay map
D. show frame relay end-to-end
Answer: C
Explanation:
Cisco Frame Relay Configurations http://www.ciscopress.com/articles/article.asp?p=170741&seqNum=9 show frame-relay map The show frame-relay map privileged EXEC mode command shows the contents of the next hop protocol address to DLCI mapping table on the router. The table contains both dynamic mapped and static mapped entries. The below example shows a sample output of the show frame-relay map command. Router#show frame-relay map Serial1/2 (up): ip 172.16.1.4 dlci 401(0x191,0x6410), dynamic, broadcast,, status defined, active Serial1/2 (up): ip 172.16.1.5 dlci 501(0x1F5,0x7C50), dynamic, broadcast,, status defined, active Serial1/2 (up): ip 172.16.1.2 dlci 301(0x12D,0x48D0), dynamic, broadcast,, status defined, active
Q2. - (Topic 1)
Which two states are the port states when RSTP has converged? (Choose two.)
A. discarding
B. listening
C. learning
D. forwarding
E. disabled
Answer: A,D
Explanation:
Understanding Rapid Spanning Tree Protocol (802.1w)
http://www.cisco.com/en/US/tech/tk389/tk621/technologies_white_paper09186a0080094cf a.shtml
Port States There are only three port states left in RSTP that correspond to the three possible operational states. The 802.1D disabled, blocking, and listening states are merged into a unique 802.1w discarding state. RSTP only has 3 port states which are discarding, learning and forwarding. When RSTP has converged there are only 2 port states left: discarding and forwarding.
Q3. DRAG DROP - (Topic 2)
Answer:
Explanation:
+ holddown timer: prevents a router from improperly reinstating a route from a regular routing update
+ split horizon: prevents information about a route from being sent in the direction from which the route was learned
+ defining a maximum: prevents invalid updates from looping the internetwork indefinitely
+ route poisoning: causes a routing protocol to advertise an infinite metric for a failed route
+ triggered update: decreases convergence time by immediately sending route information in response to a topology change
Q4. - (Topic 2)
What is the default administrative distance of OSPF?

Q5. - (Topic 3)
The command show frame-relay map gives the following output:
Serial 0 (up): ip 192.168.151.4 dlci 122, dynamic, broadcast, status defined, active
Which statements represent what is shown?(Choose three.)
A. 192.168.151.4 represents the IP address of the remote router
B. 192.168.151.4 represents the IP address of the local serial interface
C. DLCI 122 represents the interface of the remote serial interface
D. DLCI 122 represents the local number used to connect to the remote address
E. broadcast indicates that a dynamic routing protocol such as RIP v1 can send packets across this PVC
F. active indicates that the ARP process is working
Answer: A,D,E

Q6. - (Topic 2)
Refer to the exhibit.
A packet with a source IP address of 192.168.2.4 and a destination IP address of 10.1.1.4 arrives at the AcmeB router. What action does the router take?
A. forwards the received packet out the Serial0/0 interface
B. forwards a packet containing an EIGRP advertisement out the Serial0/1 interface
C. forwards a packet containing an ICMP message out the FastEthemet0/0 interface
D. forwards a packet containing an ARP request out the FastEthemet0/1 interface
Answer: C Explanation:
CCNA - EIGRP Common Question http://www.orbitco-ccna-pastquestions.com/CCNA---EIGRP-Common-Question.php
Looking at the output above, there is no IP route for 10.1.1.4 address on AcmeB routing table. If the router can no find a specific path in its routing table to a particular route,( In this case no path is found so AcmeB) the router will inform the source host with an ICMP message that the destination is unreachable and this will be through the same interface it has received the packet (interface Fa0/0 network 192.168.3.0/28 from the exhibit).

Q7. DRAG DROP - (Topic 2)
Answer:
Explanation:
Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco proprietary routing protocol, so it is vendor-specific. By default, EIGRP internal routes have an administrative distance value of 90. OSPF uses cost as its metric. By default, the cost of an interface is calculated based on bandwidth with the formula cost= 10000 0000/bandwidth (in bps). OSPF elects a DR on each broadcast and nonbroadcast multiaccess networks (like Ethernet and Frame Relay environments, respectively). It doesn’t elect a DR on point-to-point link (like a serial WAN).
Q8. - (Topic 2)
Refer to the exhibit.
If the router R1 returns the given output and has not had its router ID set manually, what address will EIGRP use as its router ID?
A. 192.168.1.2
B. 172.16.4.1
C. 192.168.10.2
D. 1.1.1.1
Answer: D
Explanation:
The router ID is selected according to the following rules: manual configuration highest up/up loopback highest up/up physical interface
Q9. - (Topic 2)
Refer to the exhibit.
Host A pings interface S0/0 on router 3, what is the TTL value for that ping?
A. 253
B. 252
C. 255
D. 254
Answer: A
Explanation:
From the CCNA ICND2 Exam book: “Routers decrement the TTL by 1 every time they forward a packet; if a router decrements the TTL to 0, it throws away the packet. This prevents packets from rotating forever.” I want to make it clear that before the router forwards a packet, the TTL is still remain the same. For example in the topology above, pings to S0/1 and S0/0 of Router 2 have the same TTL.
The picture below shows TTL values for each interface of each router and for Host B.
Notice that Host A initializes ICMP packet with a TTL of 255:
Q10. - (Topic 1)
Which term describes a spanning-tree network that has all switch ports in either the blocking or fowarding state?
A. converged
B. redundant
C. provisioned
D. spanned
Answer: A
Explanation:
Spanning Tree Protocol convergence (Layer 2 convergence) happens when bridges and switches have transitioned to either the forwarding or blocking state. When layer 2 is converged, root bridge is elected and all port roles (Root, Designated and Non-Designated) in all switches are selected.
