Exam Description
The Building Converged Cisco Multilayer Switched Networks (BCMSN 642-812) is a qualifying exam for the Cisco Certified Network Professional CCNP® and the Cisco Certified Design Professional CCDP® certifications. The BCMSN 642-812 exam will certify that the successful candidate has important knowledge and skills necessary to implement scalable multilayer switched networks. The exam includes topics on Campus Networks, describing and implementing advanced Spanning Tree concepts, VLANs and Inter-VLAN routing, High Availability, Wireless Client Access, Access Layer Voice concepts, and minimizing service Loss and Data Theft in a Campus Network.

Exam Topics
The following information provides general guidelines for the content likely to be included on the exam. However, other related topics may also appear on any specific delivery of the exam. In order to better reflect the contents of the exam and for clarity purposes the guidelines below may change at any time without notice.

Implement VLANs.
Explain the functions of VLANs in a hierarchical network.
Configure VLANs (e.g., Native, Default, Static and Access).
Explain and configure VLAN trunking (i.e., IEEE 802.1Q and ISL).
Explain and configure VTP.
Verify or troubleshoot VLAN configurations.

Conduct the operation of Spanning Tree protocols in a hierarchical network.
Explain the functions and operations of the Spanning Tree protocols (i.e., RSTP, PVRST, MISTP).
Configure RSTP (PVRST) and MISTP.
Describe and configure STP security mechanisms (i.e., BPDU Guard, BPDU Filtering, Root Guard).
Configure and Verify UDLD and Loop Guard.
Verify or troubleshoot Spanning Tree protocol operations.
Configure and verify link aggregation using PAgP or LACP.

Implement Inter-VLAN routing.
Explain and configure Inter-VLAN routing (i.e., SVI and routed ports).
Explain and enable CEF operation.
Verify or troubleshoot InterVLAN routing configurations.

Implement gateway redundancy technologies.
Explain the functions and operations of gateway redundancy protocols (i.e., HSRP, VRRP, and GLBP).
Configure HSRP, VRRP, and GLBP.
Verify High Availability configurations.

Describe and configure wireless client access.
Describe the components and operations of WLAN topologies (i.e., AP and Bridge).
Describe the features of Client Devices, Network Unification, and Mobility Platforms (i.e., CCX, LWAPP).
Configure a wireless client (i.e., ADU).

Describe and configure security features in a switched network.
Describe common Layer 2 network attacks (e.g., MAC Flooding, Rogue Devices, VLAN Hopping, DHCP Spoofing, etc.)
Explain and configure Port Security,802.1x, VACLs, Private VLANs, DHCP Snooping, and DAI.
Verify Catalyst switch (IOS-based) security configurations (i.e., Port Security, 802.1x, VACLs, Private VLANs, DHCP Snooping, and DAI).

Configure support for voice.
Describe the characteristics of voice in the campus network.
Describe the functions of Voice VLANs and trust boundaries.
Configure and verify basic IP Phone support (i.e. Voice VLAN, Trust and CoS options, AutoQoS for voice).

Question: 1
What must be the same to make multiple switches part of the same Multiple Spanning Tree
(MST)?

A – VLAN instance mapping and revision number
B – VLAN instance mapping and member list
C – VLAN instance mapping, revision number, and member list
D – VLAN instance mapping, revision number, member list, and timers
Answer: A Question: 2
Exhibit:

Refer to the exhibit. Switch P1S1 is not applying VLAN updates from switch P2S1. What are
three reasons why this is not occurring? (Choose three.)

A – Switch P2S1 is in server mode.
B – Switch P1S1 is in transparent mode. C – The MD5 digests do not match.

D – The passwords do not match.
E – The VTP domains are different.
F – VTP trap generation is disabled on both switches.
Answer: B, D, E Question: 3
Which two statements are true about HSRP, VRRP, and GLBP? (Choose two.)

A – GLBP allows for router load balancing of traffic from a network segment without the different host IP configurations required to achieve the same results with HSRP.
B – GLBP allows for router load balancing of traffic from a network segment by utilizing the creation of multiple standby groups.
C – GLBP and VRRP allow for MD5 authentication, whereas HSRP does not.
D – Unlike HSRP and VRRP, GLBP allows automatic selection and simultaneous use of multiple available gateways.
E – HSRP allows for multiple upstream active links being simultaneously used, whereas GLBP
does not.
Answer: A, D Question: 4
Exhibit:

Refer to the exhibit. Which statement is true when voice traffic is forwarded on the same VLAN
used by the data traffic?

A – Quality of service cannot be applied for the voice traffic.
B – The voice traffic cannot be forwarded to the distribution layer.
C – Port security cannot be enabled on the switch that is attached to the IP phone.
D – The voice traffic cannot use 802.1p priority tagging.
Answer: D Question: 5

Refer to the exhibit. Both host stations are part of the same subnet but are in different VLANs. On
the basis of the information presented in the exhibit, which statement is true about an attempt to ping from host to host?

A – A trunk port will need to be configured on the link between Sw_A and Sw_B for the ping command to be successful.
B – The two different hosts will need to be in the same VLAN in order for the ping command to be successful.
C – A Layer 3 device is needed for the ping command to be successful.
D – The ping command will be successful without any further configuration changes.
Answer: D Question: 6
Exhibit:

Examine the router output above. Which two items are correct? (Choose two.)

A – Router A will assume the active state if its priority is the highest.
B – If Ethernet 0/2 goes down, the standby router will take over.
C – When Ethernet 0/3 of Router A comes back up, the priority will become 105.
D – The local IP address of Router A is 10.1.0.6.

What must be configured on a Cisco switch in order to advertise VLAN information?

A – VTP password
B – VTP domain name
C – VTP revision number

Answer: B Question: 8
Exhibit:

Refer to the exhibit. The command spanning-tree bpdufilter enable is configured on interface
Fa0/1 on switch S6. The link between switch S5 and S6 fails. Will Host A be able to reach Host
B?

A – Fifty percent of the traffic will successfully reach Host B, and fifty percent will dead-end at switch S3 because of a partial spanning-tree loop.
B – No. Traffic will pass from switch S6 to S2 and dead-end at S2.
C – No. Traffic will loop back and forth between switch S6 and Host A.
D – No. Traffic will loop back and forth between switches S2 and S3.
