What CEF component maintains next-hop address information based on the information in the RIB? Cache PFC Adjaceny Table Flow FIB MSFC Question 7 of 22 8. By default, VRRP messages are sent with the plain-text key string ‘cisco’, as a simple method to authenticate VRRP peers False True Question 8 of 22 9. What is the default maximum number of secure addresses that will be learned by the switch when port security is enabled? There is no limit to the number of addresses that can be learned It depends on the CAM table space; each port is allocated a limit based on this The switch port will learn up to 2 different addresses The switch port will learn no more than 1024 address The switch port will only learn 1 address Question 9 of 22 10.

What configuration commands can be used to ensure that HSRP group 5 uses a MAC address other than the default HSRP MAC address? Select TWO answers. Switch(config)#standby use-bia Switch(config-if)#standby 1 use-bia Switch(config-if )#standby 1 mac-address aaaa.bbbb.cccc Switch(config)#standby mac-address aaaa.bbbb.cccc Switch(config)#standby 1 use bia Switch(config-if)#standby use-bia Switch(config)#standby 1 mac-address aaaa.bbbb.cccc Switch(config-if)#standby mac-address aaaa.bbbb.cccc Question 11 of 22 12. Which of the following statements about Cisco Express Forwarding (CEF) are TRUE? Select TWO answers. CEF operates at the control plane and is a demand-driven proprietary switching mechanism CEF uses a RIB to make IP destination prefix-based switching decisions CEF uses two data structures, which are the FIB and the Adjacency Table CEF uses two data structures, which are the RIB and the FIB CEF operates at the control plane and is a topology-driven proprietary switching mechanism CEF operates at the data plane and is a demand-driven proprietary switching mechanism CEF uses a PFC to make IP destination prefix-based switching decisions CEF operates at the data plane and is a topology-driven proprietary switching mechanism Question 12 of 22 13. Which of the following statements about LACP is TRUE? LACP frames are encoded with the EtherType value 0x8808 LACP frames are encoded with the EtherType value 0x8805 LACP frames are encoded with the EtherType value 0x8803 LACP frames are encoded with the EtherType value 0x8801 LACP frames are encoded with the EtherType value 0x8809 Question 13 of 22 14. Which of the following would NOT be contained in HSRP Hello messages? HSRP Timer Values The Group ID HSRP Multicast Address HSRP Authentication Information HSRP Version Question 14 of 22 15. The DCF is used in IEEE 802.11 networks to manage access to the RF medium. The DCF is composed of the following two main components. What are these two components? Select the two BEST answers. CSMA/CA Random Backoff VCS IFS NAV Question 15 of 22 16. Which of the following are valid HSRP message types? Select THREE answers. Hello Standby Active Speak Resign Coup Question 16 of 22 17. Which of the following statements about LACP is TRUE? Architecturally, the LACP application is a client to the Data Link Layer LACP packets are sent to the IEEE 802.3 Slow Protocols Multicast group address 01-80-C2-00-00-00 The LACP defines frame collection and distribution along with an LACP agent By default, all outbound packets on one link in a port channel are blocked from returning on any other link of the port channel The MAC Sub-Layer binds multiple physical ports and presents them to upper Layers of the stack as a single logical port Question 17 of 22 18. The MSFC performs control plane functions, such as learning about the networks and builds routing tables. It then builds a RIB and pushes this to the PFC. The PFC forwards packets to their respective destinations based on the next-hop entries that are located in the RIB. False True Question 18 of 22 19.
