on a data center network to provide expansion and transport flexibility
What is an advantage of PVST+

The role of the ports in all VLANs.
The root bridge BID.
Which protocol provides up to 16 instances of RSTP, combines many VLANs with the same physical and logical topology into a common RSTP instance, and provides support for PortFast, BPDU guard, BPDU filter, root guard, and loop guard?
Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation? (Choose two.)
redundant links between Layer 2 switches
removing single points of failure with multiple Layer 2 switches
If no bridge priority is configured in PVST, which criteria is considered when electing the root bridge?
lowest MAC address
What is the purpose of HSRP?
It provides a continuous network connection when a router fails.
n which two port states does a switch learn MAC addresses and process BPDUs in a PVST network? (Choose two.)
Which port state will switch ports immediately transition to when configured for PortFast?
Which three components are combined to form a bridge ID?
extended system ID
A network administrator is preparing the implementation of Rapid PVST+ on a production network. How are the Rapid PVST+ link types determined on the switch interfaces?
Link types are determined automatically.
Which two types of spanning tree protocols can cause suboptimal traffic flows because they assume only one spanning-tree instance for the entire bridged network? (Choose two.)
What additional information is contained in the 12-bit extended system ID of a BPDU?
What is a characteristic of a Layer 2 loop?
Broadcast frames are forwarded back to the sending switch.
Which nonproprietary protocol provides router redundancy for a group of routers which support IPv4 LANs?
When a range of ports is being configured for EtherChannel by the use of PAgP, which mode will form the bundled channel only if the port receives PAgP packets from another device?
Which PAgP mode combination will establish an EtherChannel?
switch 1 set to desirable; switch 2 set to desirable.
When a range of ports is being configured for EtherChannel, which mode will configure LACP so that it initiates the EtherChannel negotiation?

source MAC to destination MAC
source IP to destination IP
Which two roles are typically performed by a wireless router that is used in a home or small business?
Which three Wi-Fi standards operate in the 2.4GHz range of frequencies? (Choose three.)
What is the purpose of the Distributed Coordination Function in an IEEE 802.11 WLAN environment?
It allows a client to detect whether or not a channel is clear prior to transmission.
During which stage of establishing connectivity between a WLAN client and an AP does the client learn the MAC address of the AP?
A student uses a laptop to upload an assignment to a file server. Which wireless frame type did the laptop send to locate and associate with the campus access point?
For which discovery mode will an AP generate the most traffic on a WLAN?
What is a difference between Cisco APs that operate in a home environment and Cisco APs that operate in a corporate environment?
Some corporate AP models can operate in either autonomous mode or controller-based mode.
Which statement defines the control frame operation between two stations?
After receiving a data frame, the receiving station will send an ACK frame to the sending station if no errors are found.

Which two pieces of information are used by the OSPF MD5 algorithm to generate a signature? (Choose two.)
Why do OSPF serial interfaces usually require manual bandwidth configuration?
OSPF uses the bandwidth value to compute routes for its routing table.
Which command is used to verify that OSPF is enabled and also provides a list of the networks that are being advertised by the network?
