Q11. Which three statements about the default behaviour of eBGP sessions are true? (Choose three.) 

A. eBGP sessions between sub-ASs in different confederations transmit the next hop unchanged. 

B. The next hop in an eBGP peering is the IP address of the neighbor that announced the route. 

C. When a route reflector reflects a route to a client, it transmits the next hop unchanged. 

D. The next hop in an eBGP peering is the loopback address of the interface that originated the route. 

E. The next hop in an eBGP peering is the loopback address of the neighbor that announced the route. 

F. When a route reflector reflects a route to a client, it changes the next hop to its own address. 

Answer: A,B,C

Q13. What are the two requirements for BGP to install a classful network into the BGP routing table? (Choose two) 

A. The AS contains the entire classfull network. 

B. A classful network statement with a lower administrative distance is in the routing table. 

C. Auto-summary is enabled. 

D. A classful network statement with a classful mask is in the routing table.

Q16. Refer to the exhibit. 

Which statement is true? 

A. 2001:DB8::1/128 is a local host route, and it can be redistributed into a dynamic routing protocol. 

B. 2001:DB8::1/128 is a local host route, and it cannot be redistributed into a dynamic routing protocol. 

C. 2001:DB8::1/128 is a local host route that was created because ipv6 unicast-routing is not enabled on this router. 

D. 2001:DB8::1/128 is a route that was put in the IPv6 routing table because one of this router's loopback interfaces has the IPv6 address 2001:DB8::1/128. 

Answer:

Explanation: 

The local routes have the administrative distance of 0. This is the same adminstrative distance as connected routes. However, when you configure redistributed connected under any routing process, the connected routes are redistributed, but the local routes are not. This behavior allows the networks to not require a large number of host routes, because the networks of the interfaces are advertised with their proper masks. These host routes are only needed on the router that owns the IP address in order to process packets destined to that IP address. 

It is normal for local host routes to be listed in the IPv4 and IPv6 routing table for IP addresses of the router's interfaces. Their purpose is to create a corresponding CEF entry as a receive entry so that the packets destined to this IP address can be processed by the router itself. These routes cannot be redistributed into any routing protocol.

Q17. Which technology can create a filter for an embedded packet capture? 

A. Control plane policing 

B. Access lists 

C. NBAR 

D. Traffic shaping 

Answer:

Explanation: 

A filter can be applied to limit the capture to desired traffic. Define an Access Control List (ACL) within config mode and apply the filter to the buffer: 

ip access-list extended BUF-FILTER 

permit ip host 192.168.1.1 host 172.16.1.1 

permit ip host 172.16.1.1 host 192.168.1.1 

monitor capture buffer BUF filter access-list BUF-FILTER

Q18. Refer to the exhibit. 

If a port is configured as shown and receives an untagged frame, of which VLAN will the untagged frame be a member? 

A. VLAN 1 

B. VLAN 2 

C. VLAN 3 

D. VLAN 4 

Answer:

Explanation: 

When typing: Switch(config-if)#switchport mode? 

access Set trunking mode to ACCESS unconditionally 

dynamic Set trunking mode to dynamically negotiate access or trunk mode 

trunk Set trunking mode to TRUNK unconditionally 

and 

Switch(config-if)#switchport mode dynamic? 

auto Set trunking mode dynamic negotiation parameter to AUTO 

desirable Set trunking mode dynamic negotiation parameter to DESIRABLE 

So if we configure Fa0/1 as dynamic auto mode, it will not initiate any negotitation but waiting for the other end negotiate to be a trunk with DTP. If the other end does not ask it to become a trunk then it will become an access port. Therefore when using the “show interface fastEthernet0/1 switchport” command we will see two output lines “ Administrative Mode. dynamic auto” and “Operational Mode. static access” Note. To set this port to VLAN 2 as the output above just use one additional command. “switchport access vlan 2”. 

Now back to our question, from the output we see that Fa0/1 is operating as an access port on VLAN 2 so if it receive untagged frame it will suppose that frame is coming from VLAN 2.
