SRWE Moduel 5-6 review

What is the primary purpose of EtherChannel?

• A) To block redundant links using STP.
• B) To allow dynamic negotiation between routers.
• C) To group multiple physical Ethernet links into a single logical link.
• D) To establish a virtual interface called an Ethernet port.

When an EtherChannel is established, the resulting virtual interface is named what? Hint: When multiple physical links are bundled into a single logical link for increased bandwidth and redundancy, the new virtual interface is typically referred to by a name that indicates it represents a channel of ports.

• A) PAgP port
• B) LACP port
• C) Ether port
• D) Port channel

Which protocol can be used with EtherChannel to facilitate link aggregation in multivendor environments? Hint: In multivendor environments, the protocol used for link aggregation needs to be an open standard, not limited to one vendor.

• A) PAgP
• B) STP
• C) LACP
• D) On mode

Which of the following is NOT a mode for PAgP? Hint: One of the options refers to a mode from a different link aggregation protocol that is not proprietary to Cisco.

• A) PAgP desirable
• B) LACP active
• C) PAgP auto
• D) On

What must be consistent across all interfaces in an EtherChannel in terms of speed? Hint: For an EtherChannel to work properly, uniformity in key settings, including speed, is required across all the interfaces.

• A) All interfaces can have varying speeds.
• B) All interfaces must operate at different speeds for redundancy.
• C) All interfaces must operate at the same speed.
• D) The speed of the interfaces doesn't matter as long as they support EtherChannel.

All interfaces in an EtherChannel bundle should: Hint: For consistent traffic handling, interfaces in an EtherChannel should share the same configuration related to VLANs or be set up to handle multiple VLANs.

• A) Be assigned to different VLANs for redundancy.
• B) Operate at varying speeds.
• C) Be assigned to the same VLAN or configured as a trunk.
• D) Be physically contiguous and on the same module.

Spanning Tree Protocol (STP) prevents _ in a Layer 2 network by blocking redundant paths.

The ______ algorithm used by STP determines the best paths to the root bridge, ensuring efficient and redundant network connectivity.

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
