Question: 10

After configuring new data VLANs 1020 through 1030 on the VTP server, a network engineer notices that none of the VTP clients are receiving the updates. What is
the problem?

A. The VTP server must be reloaded.
B. The VTP version number must be set to version 3.
C. After each update to the VTP server, it takes up to 4 hours propagate.
D. VTP must be stopped and restarted on the server.
E. Another switch in the domain has a higher revision number than the server.

Correct Answer: B
Explanation: 
VTP version 3 supports these features that are not supported in version 1 or version 2:
Enhanced authentication--You can configure the authentication as hidden or secret. When hidden, the secret key from the password string is saved in the VLAN database file, but it does not appear in plain text in the configuration. Instead, the key associated with the password is saved in hexadecimal format in the running configuration. You must reenter the password if you enter a takeover command in the domain. When you enter the secret keyword, you can directly configure the password secret key.
Support for extended range VLAN (VLANs 1006 to 4094) database propagation. VTP versions 1 and 2 propagate only VLANs 1 to 1005. If extended VLANs are configured, you cannot convert from VTP version 3 to version 1 or 2.

Question: 9

A network engineer notices inconsistent Cisco Discovery Protocol neighbors according to the diagram that is provided. The engineer notices only a single neighbor that uses Cisco Discovery Protocol, but it has several routing neighbor relationships. What would cause the output to show only the single neighbor?

A. The routers are connected via a Layer 2 switch.
B. IP routing is disabled on neighboring devices.
C. Cisco Express Forwarding is enabled locally.
D. Cisco Discovery Protocol advertisements are inconsistent between the local and remote devices.

Correct Answer: A
Explanation:
If all of the routers are connected to each other using a layer 2 switch, then each router will only have the single switch port that it connects to as its neighbor. Even though multiple routing neighbors can be formed over a layer 2 network, only the physical port that it connects to will be seen as a CDP neighbor. CDP can be used to determine the physical topology, but not necessarily the logical topology.

Question: 8

An EtherChannel bundle has been established between a Cisco switch and a corporate web server. The network administrator noticed that only one of the
EtherChannel links is being utilized to reach the web server. What should be done on the Cisco switch to allow for better EtherChannel utilization to the corporate
web server?

A. Enable Cisco Express Forwarding to allow for more effective traffic sharing over the EtherChannel bundle.
B. Adjust the EtherChannel load-balancing method based on destination IP addresses.
C. Disable spanning tree on all interfaces that are participating in the EtherChannel bundle.
D. Use link-state tracking to allow for improved load balancing of traffic upon link failure to the server.
E. Adjust the EtherChannel load-balancing method based on source IP addresses.

Answer: E

Explanation

Explanation/Reference:

Explanation:
EtherChannel load balancing can use MAC addresses, IP addresses, or Layer 4 port numbers, and either source mode, destination mode, or both. The mode you
select applies to all EtherChannels that you configure on the switch. Use the option that provides the greatest variety in your configuration. For example, if the
traffic on a channel only goes to a single MAC address (which is the case in this example, since all traffic is going to the same web server), use of the destination
MAC address results in the choice of the same link in the channel each time. Use of source addresses or IP addresses can result in a better load balance.
