After some changes in the routing policy, it is noticed that the router in AS 45123 is being used as a transit AS router for several service provides.
Which configuration ensures that the branch router in AS 45123 advertises only the local networks to all SP neighbors?
A)
B)
C)
D)
- A . Option A
- B . Option B
- C . Option C
- D . Option D
D
Explanation:
By default BGP advertises all prefixes to external BGP neighbors. This means that if you are multi-homed (connected to two or more ISPs) then you might become a transit AS.
For example, ISP 2 in AS 200 can send traffic to your router in AS 100 to reach ISP 3 in AS 300 because you advertised prefixes in ISP 3 to ISP 2.
This is what will be seen in the BGP routing table of ISP1:

An engineer must establish a connection between two CE routers for two customers with overlapping IP addresses Customer_a is connected to interfaces Gig0/0, and Customer_b is connected to interfaces Gig0/1.
Routers CE1 and CE2 are configured as follows:
Drag and drop the code snippets from the right onto the boxes in the configuration to establish the needed connection. Snippets may be used more than once.
Which protocol is used to determine the NBMA address on the other end of a tunnel when mGRE is used?
- A . NHRP
- B . IPsec
- C . MP-BGP
- D . OSPF
Refer to the exhibit.
Users report that IP addresses cannot be acquired from the DHCP server. The DHCP server is configured as shown. About 300 total nonconcurrent users are using this DHCP server, but none of them are active for more than two hours per day.
Which action fixes the issue within the current resources?
- A . Modify the subnet mask to the network 192.168.1.0 255.255.254.0 command in the DHCP pool
- B . Configure the DHCP lease time to a smaller value
- C . Configure the DHCP lease time to a bigger value
- D . Add the network 192.168.2.0 255.255.255.0 command to the DHCP pool
Refer to the exhibit.
An engineer configured BGP between routers R1 and R3 The BOP peers cannot establish neighbor adjacency to be able to exchange routes.
Which configuration resolves this issue?
- A . R3router bgp 6502address-family ipv6neighbor AB01:2011:7:100::1 activate
- B . R1router bgp 6501address-family ipv6neighbor AB01:2011:7:100;:3 activate
- C . R3router bgp 6502neighbor AB01:2011:7:100::1 ebgp-muttlhop 255
- D . R1router bgp 6501 neighborAB01:2011:7:100::3ebgp-multihop255
A
Explanation:
From the output, we learned that R1 was trying to establish BGP neighbor relationship with R3 but failed. Both of them were using physical interface to establish neighbor relationship so we don’t need the “… ebgp-multihop” command here. The only reasonable answer is R3 has not been configured to activate BGP neighbor relationship with R1.
Which Layer 3 VPN attribute allows different customers to connect to the same MPLS network with overlapping IP ranges?
- A . MP-BGP
- B . VRF
- C . RT
- D . RD
How are LDP neighbors discovered?
- A . Unicast hellos are sent to directly connected neighbors IP addresses.
- B . Multicast hellos are sent to the 224.0.0.2 group address.
- C . Broadcasts hellos are sent to the 255.255.255.255 broadcast address.
- D . Multicast hellos are sent to the 224.0.0.5 group address.
Refer to the exhibit.
The IT manager received reports from users about slow application through network x.
Which action resolves the issue?
- A . Use the variance 2 command to enable load balancing.
- B . Increase the bandwidth from the service provider.
- C . Move the servers into the users subnet.
- D . Upgrade the IOS on router E.
Refer to the exhibit.
