However, pings between hosts on the 172.16.2.0/25 and 172.16.2.128/25 network are not successful. What could explain this connectivity problem?. The ip subnet-zero command has been issued on the R1 router. The RIP v2 dynamic routing protocol cannot be used across a Frame Relay network.

It is normal for Router1 to show one active neighbor at a time to prevent routing loops. Routing is not completely configured on Router3. The IP addresses are not configured properly on the Router1 and Router3 interfaces. The no auto-summary command configured on the routers prevents Router1 and Router2 from forming a neighbor relationship.

Refer to the exhibit. Given the output for this command, if the router ID has not been manually set, what router ID will OSPF use for this RouterD?. 10.1.1.2. 10.154.154.1. 172.16.5.1. D. 192.168.5.3.

Which commands are required to properly configure a router to run OSPF and to add network 192.168.16.0/24 to OSPF area 0? (Choose two). Router(config)#router ospf 1. Router(config)#router ospf 0. Router(config)#router ospf area 0. Router(config-router)#network 192.168.16.0 0.0.0.255 area 0. Router(config-router)#network 192.168.16.0 0.0.0.255 0. Router(config-router)#network 192.168.16.0 255.255.255.0 area 0.

Which parameter or parameters are used to calculate OSPF cost in Cisco routers?. Bandwidth, Delay, and MTU. Bandwidth. Bandwidth and MTU. Bandwidth, MTU, Reliability, Delay, and Load.

Refer to the exhibit. Why are two OSPF designated routers designated routers identified on Core-Router?. Core-Router is connected more than one multi-access network. The router at 208.149.23.130 is a secondary DR in case the primary fails. Two router IDs have the same OSPF priority and are therefore tied for DR election. The DR election is still underway and there are two contenders for the role.

The EIGRP configuration in the Glencoe router uses a single network statement. From the output shown in the graph would advertise these networks in EIGRP?. network 172.26.168.0 area 478. network 172.26.0.0. network 172.26.168.128 0.0.0.127. network 172.26.168.128 area 478.

Which type of EIGRP route entry describes a feasible successor?. a primary route, stored in the routing table. a backup route, stored in the routing table. a backup route, stored in the topology table. a primary route, stored in the topology table.

What is the default maximum number of equal-cost paths that can be placed into the routing table of a Cisco OSPF router?. 2. 8. 16. Unlimited.

Router 1 was just successfully rebooted. Identify the current OSPF router ID for Router 1. 208.149.23.194. 220.173.149.10. 208.149.23.162. 190.172.32.10.

Why do large OSPF networks use a hierarchical design? (Choose three). to confine network instability to single areas of the network. to reduce the complexity of router configuration. to speed up convergence. to lower costs by replacing routers with distribution layer switches. to decrease latency by increasing bandwidth. to reduce routing overhead.

What is the default administrative distance of OSPF?. 120. 100. 90. 110.

Part of the OSPF network is shown below. You work as a network technician, study the exhibits carefully. Assume that all router interfaces are operational and correctly configured. In addition,assume that OSPF has been correctly configured on router R2. How will the default route configured on R1 affect the operation of R2?. Any packet destined for a network that is not directly connected to router R2 will be dropped immediately. Any packet destined for a network that is not directly connected to router R1 will be dropped. Any packet destined for a network that is not directly connected to router R1 will be dropped. The network directly connected to a router R2 will not be able to communicate with the 172.16.100.0, 172.16.100.28 and 172.16.100.64 subnetworks. Any packet destined for a network that is not referenced in the routing table of router R2 will be directed to R1. R1 will then send that packet back to R2 and a routing loop will occur.

A network administrator is troubleshooting the OSPF configuration of routers R1 and R2. The routers cannot establish an adjacency relationship on their common Ethernet link. The graphic shows the output of the show ip ospf interface e0 command for routers R1 and R2. Based on the information in the graphic, what is the cause of this problem?. The OSPF area is not configured properly. The priority on R1 should be set higher. The cost on R1 should be set higher. The hello and dead timers are not configured properly. A backup designated router needs to be added to the network. The OSPF process ID numbers must match.

Which two values are used by Spanning Tree Protocol to elect a root bridge? (Choose two.). amount of RAM. bridge priority. IOS version. IP address. MAC address. speed of the links.

Refer to the exhibit. This command is executed on 2960Switch: 2960Switch(config)# mac-address-table static 0000.00aa.aaaa vlan 10 interface fa0/1 Which two of these statements correctly identify results of executing the command? (Choose two.). Port security is implemented on the fa0/1 interface. MAC address 0000.00aa.aaaa does not need to be learned by this switch. Only MAC address 0000.00aa.aaaa can source frames on the fa0/1 segment. Frames with a Layer 2 source address of 0000.00aa.aaaa will be forwarded out fa0/1. MAC address 0000.00aa.aaaa will be listed in the MAC address table for interface fa0/1 only.

Refer to the exhibit. Which statement is true?. The Fa0/11 role confirms that Switch A is the root bridge for VLAN 20. VLAN 20 is running the Per VLAN Spanning Tree Protocol. The MAC address of the root bridge is 0017.596d.1580. Switch A is not the root bridge, because not all of the interface roles are designated.

Switch A is not the root bridge, because not all of the interface roles are designated. RSTP cannot operate with PVST+. RSTP defines new port roles. RSTP defines no new port states. D. RSTP is a proprietary implementation of IEEE 802.1D STP. RSTP is compatible with the original IEEE 802.1D STP.

Refer to the exhibit. A junior network administrator was given the task of configuring port security on SwitchA to allow only PC_A to access the switched network through port fa0/1. If any other device is detected, the port is to drop frames from this device. The administrator configured the interface and tested it with successful pings from PC_A to RouterA, and then observes the output from these two show commands. Which two of these changes are necessary for SwitchA to meet the requirements? (Choose two.). Port security needs to be globally enabled. Port security needs to be enabled on the interface. Port security needs to be configured to shut down the interface in the event of a violation. Port security needs to be configured to allow only one learned MAC address. Port security interface counters need to be cleared before using the show command. The port security configuration needs to be saved to NVRAM before it can become active.

Which set of commands is recommended to prevent the use of a hub in the access layer?. switch(config-if)#switchport mode trunk switch(config-if)#switchport port-security maximum 1. switch(config-if)#switchport mode trunk switch(config-if)#switchport port-security mac-address 1. switch(config-if)#switchport mode access switch(config-if)#switchport port-security maximum 1. switch(config-if)#switchport mode access switch(config-if)#switchport port-security mac-address 1.
