NEW QUESTION 1
Refer to exhibit.

The tunnel between R2 and R5 is not coming up. R2, R4 and R5 do not have any routing information sources other than OSPF and no route filtering is implemented anywhere in the network. Which two actions fix the issue? (Choose Two)

• A. Redistribute connected routes to OSPF on R5.
• B. Change the tunnel destination on R2 to 192.168.2.1
• C. Advertise interface Lo0 to OSPF on R5.
• D. Configure a static route on R5 to 2.2.2.2 via 192.168.2.1
• E. Fix the OSPF adjacency issue between R2 and r5.

Answer: AC

Explanation: In order for the tunnel to be established between R2-R5 ,the R2 should have a path for the 5.5.5.5/32 route in its own routing table , and because the ospf is the only routing protocol here , so R5 has to advertise the route 5.5.5.5/32, and that is possible through these option:
1- redistribute connected route to ospf on R5 2-Advertise interface lo0 to OSPF on R5

NEW QUESTION 3
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 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

NEW QUESTION 5
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.





Refer to the topology.
SW1 Switch Management IP address is not pingable from SW4. What could be the issue?

• A. Management VLAN not allowed in the trunk links between SW1 and SW4
• B. Management VLAN not allowed in the trunk links between SW1 and SW2
• C. Management VLAN not allowed in the trunk link between SW2 and SW4
• D. Management VLAN ip address on SW4 is configured in wrong subnet
• E. Management VLAN interface is shutdown on SW4

Answer: D

Explanation: In the network, VLAN 300 is called the Management VLAN. Based on the configurations shown below, SW1 has VLAN 300 configured with the IP address of 192.168.10.1/24, while on SW4 VLAN 300 has an IP address of 192.168.100.4/24, which is not in the same subnet.

Refer to the exhibit.

Which two statements are correct? (Choose Two)

• A. The source device has name resolution configured.
• B. The source device is using two routes for the destination, learned from different protocols.
• C. A device on the path is introducing considerable delay.

Topic 17, Ticket 12 : HSRP Issue
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
===============================================================================



Solution
Steps need to follow as below:-
Since the problem is raised that DSW1 will not become active router for HSRP group 10
we will check for the HSRP configuration…





From snapshot we see that the track command given needs to be changed under active VLAN10 router
Change Required: On DSW1, related to HSRP, under vlan 10 change the given track 1 command to instead use the track 10 command.

NEW QUESTION 18
FCAPS is a network maintenance model defined by ISO. It stands for which of the following?

• A. Fault Management
• B. Action Management
• C. Configuration Management

Answer: ACE

Explanation: The FCAPS maintenance model consists of the following:
FCAPS Maintenance Tasks:
Fault – collect info from routers and switches, email at threshold limits, respond to trouble tickets Configuration – log changes to network h/w or s/w. alert relevant folks of planned changes
Accounting – invoice users
Performance – monitor network performance and deploy QoS
Security – deploy firewall, VPN, IPS, create security policy, use AAA to validate credentials, etc.
