The OSPF neighbor relationship has been lost between R1 and R3. What is causing this problem?
sh run int ; sh ip prot
The R1 network type should be changed to point-to-multipoint non-broadcast.
Connectivity from R3 to R4, R5 and R6 has been lost. How should connectivity be reestablished?
sh ip ospf n
Add an OSPF network statement for 192.168.34.0 0.0.0.255 area 1 in R3
After resolving the issues between R3 and R4, Area 2 is still experiencing routing issues. Based on the current router configurations, what needs to be resolved for routes to the networks behind R5 to be seen in the company intranet?
sh run int
Add “ip ospf authentication-key CISCO” to R4 Ethernet 0/1 and add “area 2 authentication” to the R4 OSPF routing process.
The 6.6.0.0 subnets are not reachable from R4. how should the problem be resolved?
sh ip ospf n
Remove distribute-list 64 out on R6.
Your customer have reported that when the link between R1 and R5 is down, they notice that the active router for HSRP group 1 has not failed over to the standby router for group 1. Identify the problem.
sh standby
An HSRP group track command is misconfigured
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 issue.
sh run int ; sh access-l
The ACL applied to interface is blocking HSRP hello packet exchange
The routing table of R4 shows no entries for 172.16.10.0/24 and 172.16.20.0/24. Identify which of the following is the issue preventing route entries being installed on R4 routing table?
The distribute-list configured on R4 is blocking route entries
Router R5 do not see any route entries learned from R4; what could be the issue?
sh ip prot There is an OSPF issue between R5 and R4 or DHCP or Distribute list
R5 has become partially isolated from the remainder of the network. R5 can reach devices on directly connected networks but nothing else. What is causing the problem?
Inbound distribute lists in R5
There is an issue between R2 and R4. You are to locate the problem and suggest solution to resolve the issue. The customer has disabled access to the show running-config command.
The network segment between R2 and R4 has become disconnected from the remainder of the network. How should this issue be resolved?
sh ip eigrp n; sh ip eigrp int
Move the 192.168.24.0 network to the EIGRP 1 routing process in R2 and R4.
PC2 in VLAN 200 is unable to ping the gateway address 172.16.200.1; identify the issue.
sh run int ; sh vlan
VLAN 200 not configured on SW4
Which of statement is true regarding STP issue identified with switches in the given topology?
Loopguard configured on the New_Switch places the ports in loop inconsistent state
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?
sh run int
Path cost configuration on the New_Switch
SW1 Switch Management IP address is not pingable from SW4. What could be the issue?
