Q21. - (Topic 10)
The implementations group has been using the test bed to do a ‘proof-of-concept' that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing scheme, DHCP services,
NTP services, layer 2 connectivity, FHRP services, and device security, a trouble ticket has been opened indicating that Client 1 cannot ping the 209.65.200.241 address.
Use the supported commands to isolated the cause of this fault and answer the following questions.
What is the solution to the fault condition?
A. Under the interface Serial0/0/0 configuration enter the ip nat inside command.
B. Under the interface Serial0/0/0 configuration enter the ip nat outside command.
C. Under the ip access-list standard nat_trafic configuration enter the permit 10.2.0.0
0.0.255.255 command.
D. Under the ip access-list standard nat_trafic configuration enter the permit 209.65.200.0
0.0.0.255 command.
Answer: C
Explanation:
On R1 we need to add the client IP address for reachability to server to the access list that is used to specify which hosts get NATed.
Q22. - (Topic 17)
The implementations group has been using the test bed to do a ‘proof-of-concept'
that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing schemes, DHCP services, NTP services, layer 2 connectivity, FHRP services, and device security, a trouble ticket has been opened DSW1 will not become the active router for HSRP group 10.
Use the supported commands to isolated the cause of this fault and answer the following questions.
The fault condition is related to which technology?
A. NTP
B. HSRP
C. IP DHCP Helper
D. IPv4 EIGRP Routing
E. IPv6 RIP Routing
F. IPv4 layer 3 security
G. Switch-to-Switch Connectivity
H. Loop Prevention
I. Access Vlans
Answer: B
Explanation:
On DSW1, related to HSRP, under VLAN 10 change the given track 1 command to instead use the track 10 command.
Q23. - (Topic 20)
The implementation group has been using the test bed to do an IPv6 'proof-of-concept1.
After several changes to the network addressing and routing schemes, a trouble ticket has been opened indicating that the loopback address on R1 (2026::111:1) is not able to ping the loopback address on DSW2 (2026::102:1).
Use the supported commands to isolate the cause of this fault and answer the following question.
On which device is the fault condition located?
A. R1
B. R2
C. R3
D. R4
E. DSW1
F. DSW2
G. ASW1
H. ASW2
Answer: D
Explanation:
Start to troubleshoot this by pinging the loopback IPv6 address of DSW2 (2026::102:1). This can be pinged from DSW1, and R4, but not R3 or any other devices past that point. If we look at the diagram, we see that R4 is redistributing the OSPF and RIP IPV6 routes. However, looking at the routing table we see that R4 has the 2026::102 network in the routing table known via RIP, but that R3 does not have the route:
When we look more closely at the configuration of R4, we see that it is redistributing OSPF routes into RIP for IPv6, but the RIP routes are not being redistributed into OSPF. That is why R3 sees R4 as an IPV6 OSPF neighbor, but does not get the 2026::102 network installed.
So, problem is with route redistribution on R4.
Q24. - (Topic 1)
When troubleshooting an EIGRP connectivity problem, you notice that two connected EIGRP routers are not becoming EIGRP neighbors. A ping between the two routers was successful. What is the next thing that should be checked?
A. Verify that the EIGRP hello and hold timers match exactly.
B. Verify that EIGRP broadcast packets are not being dropped between the two routers with the show ip EIGRP peer command.
C. Verify that EIGRP broadcast packets are not being dropped between the two routers with the show ip EIGRP traffic command.
D. Verify that EIGRP is enabled for the appropriate networks on the local and neighboring router.
Answer: D
Q25. - (Topic 6)
The implementations group has been using the test bed to do a ‘proof-of-concept' that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing scheme, DHCP services, NTP services, and FHRP services, a trouble ticket has been operated indicating that Client 1 cannot ping the 209.65.200.241 address.
Use the supported commands to Isolated the cause of this fault and answer the following questions.
On which device is the fault condition located?
A. R1
B. R2
C. R3
D. R4
E. DSW1
F. DSW2
G. ASW1
H. ASW2
Answer: G
Explanation:
Since the Clients are getting an APIPA we know that DHCP is not working. However, upon closer examination of the ASW1 configuration we can see that the problem is not with DHCP, but the fact that the trunks on the port channels are only allowing VLANs 1-9, when the clients belong to VLAN 10. VLAN 10 is not traversing the trunk on ASW1, so the problem is with the trunk configuration on ASW1.
Q26. - (Topic 4)
Scenario:
You have been asked by your customer to help resolve issues in their routed network. Their network engineer has deployed HSRP. On closer inspection HSRP doesn't appear to be operating properly and it appears there are other network problems as well. You are to provide solutions to all the network problems.
Examine the configuration on R5. Router R5 do not see any route entries learned from R4; what could be the issue?
A. HSRP issue between R5 and R4
B. There is an OSPF issue between R5and R4
C. There is a DHCP issue between R5 and R4
D. The distribute-list configured on R5 is blocking route entries
E. The ACL configured on R5 is blocking traffic for the subnets advertised from R4.
Answer: B
Explanation:
If we issue the "show ip route" and "show ip ospf neighbor" commands on R5, we see that there are no learned OSPF routes and he has no OSPF neighbors.

A. BGP
B. NTP
C. IP NAT
D. IPv4 OSPF Routing
E. IPv4 OSPF Redistribution
F. IPv6 OSPF Routing
G. IPv4 layer 3 security
Answer: G
Explanation:
On R1, we need to permit IP 209.65.200.222/30 under the access list.
Q29. - (Topic 5)
Scenario:
A customer network engineer has edited their OSPF network configuration and now your customer is experiencing network issues. They have contacted you to resolve the issues and return the network to full functionality.
The OSPF neighbour relationship has been lost between R1 and R3. What is causing this problem?
A. The serial interface in R1 should be taken out of the shutdown state.
B. A neighbor statement needs to be configured in R1 and R3 pointing at each other.
C. The R1 network type should be changed to point-to-multipoint non-broadcast.
D. The hello, dead and wait timers on R1 need to be reconfigured to match the values on R3.
Answer: C
Explanation:
In order for two OSPF routers to become neighbors, they must have matching network types across the links. In this case, we see that R1 has been configured as non-broadcast and R3 is using point to point non-broadcast.
This can be seen by issuing the "show running-config" command on each router, or the "show ip ospf interface" command:
Topic 6, Ticket 1: Switch Port Trunk
Topology Overview (Actual Troubleshooting lab design is for below network design)
. Client Should have IP 10.2.1.3
. EIGRP 100 is running between switch DSW1 & DSW2
. OSPF (Process ID 1) is running between R1, R2, R3, R4
. Network of OSPF is redistributed in EIGRP
. BGP 65001 is configured on R1 with Webserver cloud AS 65002
. HSRP is running between DSW1 & DSW2 Switches
The company has created the test bed shown in the layer 2 and layer 3 topology exhibits.
This network consists of four routers, two layer 3 switches and two layer 2 switches.
In the IPv4 layer 3 topology, R1, R2, R3, and R4 are running OSPF with an OSPF process number 1.
DSW1, DSW2 and R4 are running EIGRP with an AS of 10. Redistribution is enabled where necessary.
R1 is running a BGP AS with a number of 65001. This AS has an eBGP connection to AS 65002 in the ISP's network. Because the company's address space is in the private range.
R1 is also providing NAT translations between the inside (10.1.0.0/16 & 10.2.0.0/16) networks and outside (209.65.0.0/24) network.
ASW1 and ASW2 are layer 2 switches.
NTP is enabled on all devices with 209.65.200.226 serving as the master clock source.
The client workstations receive their IP address and default gateway via R4's DHCP server.
The default gateway address of 10.2.1.254 is the IP address of HSRP group 10 which is running on DSW1 and DSW2.
In the IPv6 layer 3 topology R1, R2, and R3 are running OSPFv3 with an OSPF process number 6.
DSW1, DSW2 and R4 are running RIPng process name RIP_ZONE.
The two IPv6 routing domains, OSPF 6 and RIPng are connected via GRE tunnel running
over the underlying IPv4 OSPF domain. Redistrution is enabled where necessary.
Recently the implementation group has been using the test bed to do a ‘proof-of-concept' on several implementations. This involved changing the configuration on one or more of the devices. You will be presented with a series of trouble tickets related to issues introduced during these configurations.
Note: Although trouble tickets have many similar fault indications, each ticket has its own issue and solution.
Each ticket has 3 sub questions that need to be answered & topology remains same.
Question-1 Fault is found on which device,
Question-2 Fault condition is related to,
Question-3 What exact problem is seen & what needs to be done for solution
Client is unable to ping IP 209.65.200.241
Solution
Steps need to follow as below:-
. When we check on client 1 & Client 2 desktop we are not receiving DHCP address from R4
Ipconfig ----- Client will be getting 169.X.X.X
. On ASW1 port Fa1/0/ 1 & Fa1/0/2 access port VLAN 10 was assigned which is using IP address 10.2.1.0/24
Sh run ------- & check for running config of int fa1/0/1 & fa1/0/2
====================================================
interface FastEthernet1/0/1switchport mode accessswitchport access vlan 10interface
FastEthernet1/0/2switchport mode accessswitchport access vlan 10
====================================================
. We need to check on ASW 1 trunk port the trunk Po13 & Po23 were receiving VLAN 20 & 200 but not VLAN 10 so that switch could not get DHCP IP address and was failing to reach IP address of Internet
. Change required: On ASW1 below change is required for switch-to-switch Connectivity..
int range portchannel13,portchannel23 switchport trunk allowed vlan none switchport trunk allowed vlan 10,200
