NetAcad SRWE (v7) Module 5 & 6 Module Exam Prep

What are two advantages of using LACP? (Choose two.)

• LACP allows Fast Ethernet and Gigabit Ethernet

  interfaces to be mixed within a single EtherChannel.

• It eliminates the need for configuring trunk interfaces

  when deploying VLANs on multiple switches.

• It allows directly connected switches to negotiate an

  EtherChannel link.

• It provides a simulated environment for testing link

  aggregation.

• It allows the use of multivendor devices.

What are two advantages of EtherChannel? (Choose two.)

• Configuring the EtherChannel interface provides

  consistency in the configuration of the physical links.

• Load balancing occurs between links configured as

  different EtherChannels.

• EtherChannel uses upgraded physical links to provide

  increased bandwidth.

• Spanning Tree Protocol views the physical links in an

  EtherChannel as one logical connection.

• Spanning Tree Protocol ensures redundancy by transitioning

  failed interfaces in an EtherChannel to a forwarding state.

Which three components are combined to form a bridge ID?

• port ID

• IP address

• extended system ID

• MAC address

• bridge priority

In which two port states does a switch learn MAC addresses and process BPDUs in a PVST network? (Choose two.)

• blocking

• disabled

• forwarding

• learning

• listening

If no bridge priority is configured in PVST, which criteria is considered when electing the root bridge?

• lowest IP address

• lowest MAC address

• highest IP address

• highest MAC address

Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation? (Choose two.)

• static default routes

• implementing VLANs to contain broadcasts

• redundant links between Layer 2 switches

• link-state dynamic routing that provides redundant

  routes

• removing single points of failure with multiple Layer 2

  switches

What is the outcome of a Layer 2 broadcast storm?

• Routers will take over the forwarding of frames as

  switches become congested.

• New traffic is discarded by the switch because it is

  unable to be processed.

• CSMA/CD will cause each host to continue transmitting

  frames.

• ARP broadcast requests are returned to the transmitting

  host.

When the show spanning-tree vlan 33command is issued on a switch, three ports are shown in the forwarding state. In which two port roles could these interfaces function while in the forwarding state? (Choose two.)

• disabled

• designated

• root

• alternate

• blocked

A set of switches is being connected in a LAN topology. Which STP bridge priority value will make it least likely for the switch to be selected as the root?

• 4096

• 32768

• 61440

• 65535

What is the function of STP in a scalable network?

• It decreases the size of the failure domain to contain

  the impact of failures.

• It protects the edge of the enterprise network from

  malicious activity.

• It disables redundant paths to eliminate Layer 2 loops.

• It combines multiple switch trunk links to act as one

  logical link for increased bandwidth.
