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

ipconfig ----- Client will be receiving IP address 10.2.1.3
u2711 From Client PC we can ping 10.2.1.254u2026.
u2711 But IP 10.2.1.3 is not able to ping from R4, R3, R2, R1
u2711 Change required: On DSW1, VALN ACL, Need to delete the VLAN access-map test1 whose action is to drop access-list 10; specifically 10.2.1.3

Client is unable to ping IP 209.65.200.241u2026
Solution
Steps need to follow as below:-
u2711 When we check on client 1 & Client 2 desktop we are not receiving DHCP address from R4
u2711 Ipconfig ----- Client will be receiving IP address 10.2.1.3
u2711 IP 10.2.1.3 will be able to ping from R4 , R3, R2, R1
u2711 Look for BGP Neighbourship
u2711 Sh ip bgp summary ----- State of BGP will be in active state. This means connectivity issue between serial
u2711 Check for running config. i.e sh run --- over here check for access-list configured on interface as BGP is down (No need to check for NAT configuration as its configuration should be right as first need to bring BGP up)
u2711 In above snapshot we can see that access-list of edge_security on R1 is not allowing wan IP network
u2711 Change required: On R1, we need to permit IP 209.65.200.222/30 under the access list.

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 SerialO/0/0.23 configuration enter the ipv6 ospf 6 area 0 command.
B. Under the interface SerialO/0/0.12 configuration enter the ipv6 ospf 6 area 12 command.
C. Under ipv6 router ospf 6 configuration enter the network 2026::1:/122 area 0 command.
D. Under ipv6 router ospf 6 configuration enter the no passive-interface default command
Answer: A
Explanation:
As explained in question one of this ticket, we can then see that OSPFv3 has not been enabled on the interface to R3:
Screen Shot 2015-03-11 at 10
So the problem is with R2, related to IPV6 Routing, and the fix is to enable the u201cipv6 ospf 6 area 0u201dcommand under the serial 0/0/0.23 interface. We need to enable this interface for area 0 according to the topology diagram.

New Questions 15
A customer network engineer has made configuration changes that have resulted in some loss of connectivity. You have been called in to evaluate a switch network and suggest resolutions to the problems.
You have configured PVST+ load balancing between SW1 and the New_Switch in such a way that both the links E2/2 and E2/3 are utilized for traffic flow, which component of the configuration is preventing PVST+ load balancing between SW1 and SW2 links
A. Port priority configuration on SW1
B. Port priority configuration on the New_Switch
C. Path cost configuration on SW1
D. Path cost configuration on the New_Switch
Answer: D
Explanation:
Here is the configuration found on the New_Switch:
This causes the port cost for link eth 1/3 to increase the path cost to 250 for all VLANs, making that link less preferred so that only eth 1/2 will be used.
New Questions 16
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.
The following debug messages are noticed for HSRP group 2. But still neither R1 nor R2 has identified one of them as standby router. Identify the reason causing the issue.

C. There is an HSRP group number mismatch
D. This is not an HSRP issue: this is DHCP issue.
E. The ACL applied to interface is blocking HSRP hello packet exchange
Answer: E
