Latest and Most Accurate Cisco 300-160 Exam Questions:
Which statement is true about an IPsec/GRE tunnel?
A. The GRE tunnel source and destination addresses are specified within the IPsec transform set.
B. An IPsec/GRE tunnel must use IPsec tunnel mode.
C. GRE encapsulation occurs before the IPsec encryption process.
D. Crypto map ACL is not needed to match which traffic will be protected.
You are troubleshooting an issue with a GRE tunnel between R1 and R2 and find that routing is OK on all intermediary routers. The tunnel is up on R1, but down on R2. Which two possible issues can prevent the tunnel from coming up? (Choose Two)
A. The tunnel does not come up unless traffic is sent through it.
B. The tunnel source interface is down on R2.
C. No specific route interface is down on R2.
D. R2 does not know how to reach the tunnel destination.
E. The tunnel keep alive timer doesn’t match on R1 and R2.
Four Different Tunnel States
There are four possible states in which a GRE tunnel interface can be:
1. Up/up – This implies that the tunnel is fully functional and passes traffic. It is both adminstratively up and it’s protocol is up as well.
2. Adminstratively down/down – This implies that the interface has been administratively shut down.
3. Up/down – This implies that, even though the tunnel is administratively up, something causes the line protocol on the interface to be down.
4. Reset/down – This is usually a transient state when the tunnel is reset by software. This usually happens when the tunnel is misconfigured with a Next Hop Server (NHS) that is it’s own IP address.
When a tunnel interface is first created and no other configuration is applied to it, the interface is not shut by default:
Refer to the Exhibit:
Which output is expected in the blank line for the OSPF adjacency process?
You can check the output of “debug ip ospf adj” here:
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.
D. The source device is loading balancing traffic.
Router traces domain name (cisco.com) and it gets ICMP answers, so name resolution has happened.
Per hop output shows 2 lines, hence 2 active paths exist.
Refer to exhibit:
After a junior technician configures a new branch office GRE tunnel, which step is missing from the configuration to pass traffic through tunnel on Router 1?
A. static route to 10.0.3.0/24 via 10.0.1.1
B. static route to 10.0.3.0/24 via 10.0.2.1
C. static route to 10.0.3.0/24 via 188.8.131.52
D. static route to 10.0.3.0/24 via 184.108.40.206
