Q22. A network engineer finds that a core router has crashed without warning. In this situation, which feature can the engineer use to create a crash collection? 

A. secure copy protocol 

B. core dumps 

C. warm reloads 

D. SNMP 

E. NetFlow 

Answer:

Explanation: 

When a router crashes, it is sometimes useful to obtain a full copy of the memory image (called a core

dump) to identify the cause of the crash. Core dumps are generally very useful to your technical support representative.

Four basic ways exist for setting up the router to generate a core dump:

Using Trivial File Transfer Protocol (TFTP)

Using File Transfer Protocol (FTP)

Using remote copy protocol (rcp)

Using a Flash disk Reference: http://www.cisco.com/en/US/docs/internetworking/troubleshooting/guide/

Q23. Which address is used by the Unicast Reverse Path Forwarding protocol to validate a packet against the routing table? 

A. source address 

B. destination address 

C. router interface 

D. default gateway 

Answer:

Explanation: 

The Unicast RPF feature helps to mitigate problems that are caused by the introduction of

malformed or forged (spoofed) IP source addresses into a network by discarding IP packets that lack a

verifiable IP source address. For example, a number of common types of denial-of-service (DoS) attacks,

including Smurf and Tribal Flood Network (TFN), can take advantage of forged or rapidly changing source

IP addresses to allow attackers to thwart efforts to locate or filter the attacks. For Internet service providers

(ISPs) that provide public access, Unicast RPF deflects such attacks by forwarding only packets that have

source addresses that are valid and consistent with the IP routing table. This action protects the network of

the ISP, its customer, and the rest of the Internet. Reference: http://www.cisco.com/en/US/docs/ios/12_2/

Q24. An organization decides to implement NetFlow on its network to monitor the fluctuation of traffic that is disrupting core services. After reviewing the output of NetFlow, the network engineer is unable to see OUT traffic on the interfaces. What can you determine based on this information? 

A. Cisco Express Forwarding has not been configured globally. 

B. NetFlow output has been filtered by default. 

C. Flow Export version 9 is in use. 

D. The command ip flow-capture fragment-offset has been enabled. 

Answer:

Explanation: 

We came across a recent issue where a user setup a router for NetFlow export but was unable to see the

OUT traffic for the interfaces in NetFlow Analyzer. Every NetFlow configuration aspect was checked and

nothing incorrect was found. That is when we noticed the `no ip cef' command on the router. CEF was

enabled at the global level and within seconds, NetFlow Analyzer started showing OUT traffic for the

interfaces. This is why this topic is about Cisco Express Forwarding.

What is switching?

A Router must make decisions about where to forward the packets passing through. This decision-making

process is called "switching". Switching is what a router does when it makes the following decisions:

1.Whether to forward or not forward the packets after checking that the destination for the packet is

reachable.

2.If the destination is reachable, what is the next hop of the router and which interface will the router use to

get to that destination.

What is CEF?

CEF is one of the available switching options for Cisco routers. Based on the routing table, CEF creates its

own table, called the Forwarding Information Base (FIB). The FIB is organized differently than the routing

table and CEF uses the FIB to decide which interface to send traffic from. CEF offers the following

benefits:

1.Better performance than fast-switching (the default) and takes less CPU to perform the same task.

2.When enabled, allows for advanced features like NBAR

3.Overall, CEF can switch traffic faster than route-caching using fast-switching

How to enable CEF?

CEF is disabled by default on all routers except the 7xxx series routers. Enabling and Disabling CEF is

easy. To enable CEF, go into global configuration mode and

enter the CEF command.

Router# config t

Router(config)# ip cef

Router(config)#

To disable CEF, simply use the `no' form of the command, ie. `no ip cef`.

Why CEF Needed when enabling NetFlow ?

CEF is a prerequisite to enable NetFlow on the router interfaces. CEF decides through which interface

traffic is exiting the router. Any NetFlow analyzer product will calculate the OUT traffic for an interface

based on the Destination Interface value present in the NetFlow packets exported from the router. If the

CEF is disabled on the router, the NetFlow packets exported from the router will have "Destination

interface" as "null" and this leads NetFlow Analyzer to show no OUT traffic for the interfaces. Without

enabling the CEF on the router, the NetFlow packets did not mark the destination interfaces and so

NetFlow Analyzer was not able to show the OUT traffic for the interfaces. Reference: https://

Q27. What are the three modes of Unicast Reverse Path Forwarding? 

A. strict mode, loose mode, and VRF mode 

B. strict mode, loose mode, and broadcast mode 

C. strict mode, broadcast mode, and VRF mode 

D. broadcast mode, loose mode, and VRF mode 

Answer:

Explanation: 

Network administrators can use Unicast Reverse Path Forwarding (Unicast RPF) to help limit

the malicious traffic on an enterprise network. This security feature works by enabling a router to verify the

reachability of the source address in packets being forwarded. This capability can limit the appearance of

spoofed addresses on a network. If the source IP address is not valid, the packet is discarded. Unicast

RPF works in one of three different modes: strict mode, loose mode, or VRF mode. Note that not all

network devices support all three modes of operation. Unicast RPF in VRF mode will not be covered in this

document. When administrators use Unicast RPF in strict mode, the packet must be received on the

interface that the router would use to forward the return packet. Unicast RPF configured in strict mode may

drop legitimate traffic that is received on an interface that was not the router's choice for sending return

traffic. Dropping this legitimate traffic could occur when asymmetric routing paths are present in the

network. When administrators use Unicast RPF in loose mode, the source address must appear in the

routing table. Administrators can change this behavior using the allow-default option, which allows the use

of the default route in the source verification process. Additionally, a packet that contains a source address

for which the return route points to the Null 0 interface will be dropped. An access list may also be

specified that permits or denies certain source addresses in Unicast RPF loose mode. Care must be taken

to ensure that the appropriate Unicast RPF mode (loose or strict) is configured during the deployment of

this feature because it can drop legitimate traffic. Although asymmetric traffic flows may be of concern

when deploying this feature, Unicast RPF loose mode is a scalable option for networks that contain

asymmetric routing paths. Reference: http://www.cisco.com/web/about/security/intelligence/unicastrpf.

Q30. A user is having issues accessing file shares on a network. The network engineer advises the user to open a web browser, input a prescribed IP address, and follow the instructions. After doing this, the user is able to access company shares. Which type of remote access did the engineer enable? 

A. EZVPN 

B. IPsec VPN client access 

C. VPDN client access 

D. SSL VPN client access 

Answer:

Explanation: 

The Cisco AnyConnect VPN Client provides secure SSL connections to the security

appliance for remote users. Without a previously installed client, remote users enter the IP address in their

browser of an interface configured to accept SSL VPN connections. Unless the security appliance is

configured to redirect http:// requests to https://, users must enter the URL in the form https://<address>.

After entering the URL, the browser connects to that interface and displays the login screen. If the user

satisfies the login and authentication, and the security appliance identifies the user as requiring the client, it

downloads the client that matches the operating system of the remote computer. After downloading, the

client installs and configures itself, establishes a secure SSL connection and either remains or uninstalls

itself (depending on the security appliance configuration) when the connection terminates. Reference:
