Refer to the exhibit. Routers A and B are directly connected and running OSPF, but they are unable to form a neighbor relationship. What is the most likely cause?

Based on the network provided in the exhibit, how to route the traffic arriving at PG-R1 for 10.1.3.1?

Study the exhibit carefully. Two directly connected routers are configured with OSPF. The output presented in the exhibit can be seen on the console of one router. What most likely cause this problem?

For the following ports, which port is on every bridge in a Spanning Tree Protocol IEEE 802.1w network except the root bridge? (Exhibit)

Study the exhibit carefully. In this network, if all required configurations are true for routing. Subnet 10.1.1.0/24 is sourced by PG-A and advertised via BGP, OSPF, and EIGRP. Finally, PG-G knows this subnet. Which routing protocol and administrative distance can be used by PG-G to reach subnet 10.1.1.0/24?

Refer to the exhibit. Based on the configuration shown, which queuing mechanism has been configured on interface serial 1/0?

Refer to the exhibit. The Layer 2 network uses VTP to manage its VLAN database. A network designer created all VLANs on the VTP server (switch 1) and it has been advertised through VTP to all other VTP clients (switches 2 through 4). Due to network growth, a network operator decided to add a new switch between switch 1 and switch 3. The network operator has been instructed to use a refurbished switch and use a VTP client. Which three of these factors should the network operator consider to minimize the impact of adding a new switch? (Choose three.)

Refer to the exhibit. Look at the command output. What can you use to prevent this behavior?

You are about to migrate a customer network to use a VSS. Which of these statements is true about a VSS? (Exhibit)

An 802.1Q trunk is not coming up between two switches. The ports on both switches are configured as "switchport mode desirable." Assuming that there is no physical issue, choose two possible causes. (Choose two.)
