Which of the following routing protocols is classified as an Exterior Gateway Protocol ?

• Routing Information Protocol (RIP)

• • Enhanced Interior Gateway Routing Protocol (EIGRP)

• • Open Shortest Path First (OSPF)

• Intermediate System-to-Intermediate System (IS-IS) protocol

• Border Gateway Protocol (BGP)

• What are two functions of a router? (Choose two.)

• 
  It connects multiple IP networks.

• 
  It controls the flow of data via the use of Layer 2 addresses.

• It determines the best path to send packets.

• It manages the VLAN database.

• 
  It increases the size of the broadcast domain.

By default all the switch ports are unprotected.

• True

• False

Switches operate Half-Duplex.

• True

• False

Bridge ID is consist of ____ and ____

• Switch ID

• IP address

• MAC address

• Bridge Priority

• System ID

Which statement is true about the port roles of the 802.1w Rapid Spanning Tree Protocol ?

• Cisco-proprietary enhancements to the legacy 802.1D, such as UplinkFast and BackboneFast, are compatible with RSTP

• 
  It takes an edge port 15 seconds to go from blocking to forwarding

• An alternate or backup port can immediately change to a forwarding state without waiting for the network to converge

• Ports are manually configured to be in the designated role

What is the goal of Layer 3 switching ?

• to process packets at Layer 2 switching speeds while utilizing the scalability of routing

• to implement the routing process by using routed protocols

• to provide a better path to the Internet without using routing protocols

• to integrate all of the networking functions into one device

What is a benefit of deploying an on-premises infrastructure versus a cloud infrastructure deployment ?

• ability to quickly increase compute power without the need to install additional hardware

• less power and cooling resources needed to run infrastructure on-premises

• faster deployment times because additional infrastructure does not need to be purchased

• lower latency between systems that are physically located near each other
