Q11. The implementations group has been using the test bed to do a u2021proof-of-conceptu2021 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 indicating that Client 1 cannot ping the 209.65.200.241 address.
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:
On R4 the DHCP IP address is not allowed for network 10.2.1.0/24 which clearly shows the problem lies on R4 & the problem is with DHCP
Topic 19, Ticket 14: IPv6 Routing Issue 1
Topology Overview (Actual Troubleshooting lab design is for below network design)
u2711 Client Should have IP 10.2.1.3
u2711 EIGRP 100 is running between switch DSW1 & DSW2
u2711 OSPF (Process ID 1) is running between R1, R2, R3, R4
u2711 Network of OSPF is redistributed in EIGRP
u2711 BGP 65001 is configured on R1 with Webserver cloud AS 65002
u2711 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 ISPu2021s network. Because the companyu2021s 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 R4u2021s 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 u2021proof-of-conceptu2021 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

Answer: A,E,F
Q13. The implementations group has been using the test bed to do a u2021proof-of-conceptu2021 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.
Which is the solution to the fault condition?
A. Under the EIGRP process, delete the redistribute ospf 1 route-map OSPF_ to_ EIGRP command and enter the redistribute ospf 1 route-map OSPF - > EIGRP command.
B. Under the EIGRP process, delete the redistribute ospf 1 route-map OSPF_ to_ EIGRP command and enter the redistribute ospf 6 metric route-map OSPF - > EIGRP command.
C. Under the OSPF process, delete the redistribute eigrp10 subnets route-map EIGPR -
>OSPF command and enter the redistribute eigrp10 subnets route-map OSPF - > EIGRP command.
D. Under the OSPF process, delete the redistribute eigrp10 subnets route-map EIGPR -
>OSPF command and enter the redistribute eigrp10 subnets route-map EIGPR - > OSPF command.
E. Under the EIGRP process, delete the redistribute ospf 1 route-map OSPF _to_ EIGRP command and enter redistribute ospf 1 metric 100000 100 100 1 15000 route_ map OSPF
_to _EIGRP command
Answer: A
Explanation:
On R4, in the redistribution of EIGRP routing protocol, we need to change name of route- map to resolve the issue. It references route-map OSPF_to_EIGRP but the actual route map is called OSPF->EIGRP.
Q14. The implementations group has been using the test bed to do a u2021proof-of-conceptu2021 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 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.
The fault condition is related to which technology?
A. NTP
B. Switch-to-Switch Connectivity
C. Access Vlans
D. Port Security
E. VLAN ACL / Port ACL
F. Switch Virtual Interface
Answer: B
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 switch to switch connectivity, specifically the trunk configuration on ASW1.
Q15. Which of the following are byproducts of a structured maintenance plan? (Choose all that apply.)
A. Predictable security vulnerabilities
B. Economies of scale
C. Improved expenditure forecasts
D. Increased downtime
E. Predictable equipment obsolescence
F. Consumption of fewer resources
Answer: A,B,C,E,F
Q16. 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.
What is the solution to the fault condition?
A. Under the interface Tunnel34 configuration delete the tunnel mode ipv6 command.
B. Under the interface Serial0/0/0.34 configuration enter the ipv6 address 2026::34:1/122 command.
C. Under the interface Tunnel34 configuration enter the ip address unnumbered Serial0/0/0.34 command.
D. Under the interface Tunnel34 configuration delete the tunnel source Serial0/0/0.34 command and enter the tunnel source 2026::34:1/122 command.
Answer: A
Explanation:
As explained earlier, the problem is with route misconfigured tunnel modes on R3. R3 is using tunnel mode ipv6, while R4 is using the default of GRE. We need to remove the u201ctunnel mode ipv6u201d command under interface Tunnel34
