The feature that enables an interface on an EX Series switch to receive both untagged traffic (from the computer) and tagged traffic (from the IP phone) is thevoice VLAN12.

The voice VLAN feature in EX-series switches enables access ports to accept both data (untagged) and voice (tagged) traffic and separate that traffic into different VLANs12.This allows the switch to differentiate between voice and data traffic, ensuring that voice traffic can be treated with a higher priority12. Therefore, option D is correct.

The output shown in the exhibit is a brief display of the Ethernet switching table, which shows the learned Layer 2 MAC addresses for each VLAN and interface1.

The commandshow ethernet-switching tabledisplays the Ethernet switching table with brief information, such as the destination MAC address, the VLAN name, the forwarding state, and the interface name1.

The commandshow route forwarding-tabledisplays the routing table information for each protocol family, such as inet, inet6, mpls, iso, and so on2. It does not show the Ethernet switching table or the MAC addresses.

The commandshow ethernet-switching table extensivedisplays the Ethernet switching table with extensive information, such as the destination MAC address, the VLAN name, the forwarding state, the interface name, the VLAN index, and the tag type1. It shows more details than the brief output shown in the exhibit.

The commandshow route forwarding-table family ethernet-switchingdisplays the routing table information for the ethernet-switching protocol family, which shows the destination MAC address, the next-hop MAC address, and the interface name3. It does not show the VLAN name or the forwarding state.

Ais correct because generated routes require a contributing route.A contributing route is a route that matches the destination prefix of the generated route and has a valid next hop1.A generated route is only installed in the routing table if there is at least one contributing route available2. This ensures that the generated route is reachable and useful.If there is no contributing route, the generated route is not added to the routing table2.

Bis correct because generated routes show a next hop in the routing table.A generated route inherits the next hop of its primary contributing route, which is the most preferred route among all the contributing routes2.The next hop of the generated route can be either an IP address or an interface name, depending on the type of the contributing route2.The next hop of the generated route can also be modified by a routing policy3.

The output shown in the exhibit is the result of the command ''show ip bgp neighbor 10.36.1.4 received-routes'', which displays all received routes (both accepted and rejected) from the specified neighbor.

Option A is correct, because the routes displayed have traversed one or more autonomous systems. This can be seen from the AS_PATH attribute, which shows the sequence of AS numbers that the route has passed through. For example, the route 10.0.0.0/8 has an AS_PATH of 65001 65002, which means that it has traversed AS 65001 and AS 65002 before reaching the local router.

Option B is correct, because the output shows routes that were received prior to the application of any BGP import policies. This can be seen from the fact that some routes have a status code of ''r'', which means that they are rejected by an import policy. The ''received-routes'' keyword shows the routes coming from a given neighbor before the inbound policy has been applied. To see the routes after the inbound policy has been applied, the ''routes'' keyword should be used instead.

Option C is incorrect, because the output does not show routes that are active and rejected by an import policy. The status code of ''r'' means that the route is rejected by an import policy, but it does not mean that it is active. The status code of ''>'' means that the route is active and selected as the best path. None of the routes in the output have both ''>'' and ''r'' status codes.

Option D is incorrect, because the routes displayed are not being learned from an IBGP peer. An IBGP peer is a BGP neighbor that belongs to the same AS as the local router. The output shows that the neighbor 10.36.1.4 has a remote AS of 65001, which is different from the local AS of 65002. Therefore, the neighbor is an EBGP peer, not an IBGP peer.

The exhibit shows the output of the commandshow ospf neighbor, which displays information about the OSPF neighbors on a router1.

The output shows that the OSPF neighbor with the address 172.26.1.1 and the interface ge-0/0/3.0 is in the Exstart state1.

The Exstart state is the fourth state in the OSPF neighbor formation process, after Down, Init, and 2-Way states2.In this state, the OSPF neighbors establish a master-slave relationship and exchange database description (DBD) packets, which contain summaries of their link-state databases2.

The most common reason for OSPF neighbors to be stuck in the Exstart state is an MTU mismatch between the interfaces3.MTU stands for maximum transmission unit, which is the largest size of a packet that can be transmitted on a network segment4.If the MTU values of two OSPF neighbors are different, they may not be able to exchange DBD packets successfully, as some packets may be dropped or fragmented due to their size exceeding the MTU limit3.

To solve this problem, you need to ensure that the MTU values of both OSPF neighbors are the same or compatible.You can use the commandshow interfacesto display the MTU value of an interface5. You can also use the commandpingwith thedo-not-fragmentoption to test the MTU size between two routers.You can change the MTU value of an interface by using the commandset interfaces interface-name mtu mtu-valuein configuration mode5.
