Question #1
Refer to the exhibit. The output that is shown is generated at a switch. Which three statements are true? (Choose three.)
Select 3 answers.
Please select an optionIncorrectCorrect answer: A, C, E
From the output, we see that all ports are in Designated role (forwarding state) -> A and E are correct. The command "show spanning-tree vlan 30" only shows us information about VLAN 30. We don't know how many VLANs exist in this switch -> B is not correct. The bridge priority of this switch is 24606 which is lower than the default bridge priority 32768 -> C is correct. All three interfaces on this switch have the connection type "p2p", which means point-to-point environment, not a shared media -> D is not correct. The only thing we can specify is this switch is the root bridge for VLAN 30 but we cannot guarantee it is also the root bridge for other VLANs -> F is not correct.
Was this answer correct?Question #2
Which term describes a spanning-tree network that has all switch ports in either the blocking or forwarding state?
Please select an optionIncorrectCorrect answer: A
Spanning Tree Protocol convergence (Layer 2 convergence) happens when bridges and switches have transitioned to either the forwarding or blocking state. When layer 2 is converged, root bridge is elected and all port roles (Root, Designated and Non-Designated) in all switches are selected.
Was this answer correct?Question #3
Refer to the exhibit. Why has this switch not been elected the root bridge for VLAN1?
Please select an optionIncorrectCorrect answer: D
When a switch receives a BPDU, it first compares priority; the lower number wins. If a tie, compare MAC; the smaller one wins. Here the switch has bridge priority 32769 which is greater than the root priority 20481, so this switch has a higher bridge ID than the elected root and is not the root bridge for VLAN 1.
Was this answer correct?Question #4
Which three of these statements regarding 802.1Q trunking are correct? (Choose three.)
Select 3 answers.
Please select an optionIncorrectCorrect answer: A, C, E
Native VLAN frames are sent untagged by default, 802.1Q trunks can run on 10 Mb/s Ethernet, and the native VLAN must match at both ends. Trunks do not require full duplex, and trunk ports cannot also be port-security ports.
Was this answer correct?Question #5
What is one benefit of PVST+?
Please select an optionIncorrectCorrect answer: C
Per VLAN Spanning Tree (PVST) Introduction http://www.cisco.com/en/US/tech/tk389/tk621/tk846/tsd_technology_support_sub-protocol_home.html Per VLAN Spanning Tree (PVST) maintains a spanning tree instance for each VLAN configured in the network. This means a switch can be the root bridge of a VLAN while another switch can be the root bridge of other VLANs in a common topology. For example, Switch 1 can be the root bridge for Voice data while Switch 2 can be the root bridge for Video data. If designed correctly, it can optimize the network traffic. http://www.ciscopress.com/articles/article.asp?p=102157&seqNum=4
Was this answer correct?Question #6
Refer to the exhibit. At the end of an RSTP election process, which access layer switch port will assume the discarding role?
Please select an optionIncorrectCorrect answer: C
Only the access layer switches (Switch3 and Switch4) matter. Switch3 has a lower bridge ID than Switch4 (lower MAC), so both Switch3 ports forward and the alternate (discarding) port is on Switch4. Switch4 chooses its root port from the superior BPDU: same root ID, same cost and same sender bridge ID, so the sender port ID decides. Fa0/1 (128.1) is lower than Fa0/12 (128.12), so the port connected to Fa0/1 (Switch4 Fa0/2) becomes the root port and Switch4 Fa0/11 becomes the alternate port in discarding state.
Was this answer correct?Question #7
Which three statements about RSTP are true? (Choose three.)
Select 3 answers.
Please select an optionIncorrectCorrect answer: A, B, D
RSTP converges much faster after a link failure, adds the alternate and backup port roles, and moves point-to-point links to forwarding quickly via proposal-agreement rather than STP timers. RSTP port states are discarding, learning and forwarding only.
Was this answer correct?Question #8
Which two are advantages of static routing when compared to dynamic routing? (Choose two.)
Select 2 answers.
Please select an optionIncorrectCorrect answer: B, G
Static routes are entered manually, so only the administrator can change the routing table (security), and no routing updates are exchanged, which reduces traffic on stub links. The other options describe dynamic routing.
Was this answer correct?Question #9
Which two statements describe the process identifier that is used in the command to configure OSPF on a router? (Choose two.) Router(config)# router ospf 1
Select 2 answers.
Please select an optionIncorrectCorrect answer: C, D
we all know that The areas can be any number from 0 to 4.2 billion and 1 to 65,535 for the Process ID. The process ID is the ID of the OSPF process to which the interface belongs. The process ID is local to the router, and two OSPF neighboring routers can have different OSPF process IDs. (This is not true of Enhanced Interior Gateway Routing Protocol [EIGRP], in which the routers need to be in the same autonomous system). Cisco IOS Software can run multiple OSPF processes on the same router, and the process ID merely distinguishes one process from the another. The process ID should be a positive integer.
Was this answer correct?Question #10
Refer to the exhibit. The Lakeside Company has the internetwork in the exhibit. The administrator would like to reduce the size of the routing table on the Central router. Which partial routing table entry in the Central router represents a route summary that represents the LANs in Phoenix but no additional subnets?
Please select an optionIncorrectCorrect answer: D
All the above networks can be summarized to 10.0.0.0 network but the question requires to “represent the LANs in Phoenix but no additional subnets” so we must summarized to 10.4.0.0 network. The Phoenix router has 4 subnets so we need to “move left” 2 bits of “/24-> /22 is the best choice - D is correct.
