This Exam contains:

-Guarantee passing score -100 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: What will happen if a private IP address is assigned to a public interface connected to an ISP?A conflict of IP addresses happens, because other public routers can use the same range.Addresses in a private range will not be routed on the Internet backbone.Only the ISP router will have the capability to access the public network.The NAT process will be used to translate this address to a valid IP address.

Answer:

Addresses in a private range will not be routed on the Internet backbone.Question 2: Which three options are the major components of a network virtualization architecture? (Choose three) virtual network services authentication services network access control network resilience path isolation policy enforcement

Answer:

virtual network services network access control path isolation

Question 3: Which two options are the best reasons to use an IPV4 private IP space? (Choose two) to enable intra-enterprise communication to conserve global address space to manage routing overhead to connect applications to implement NAT

Answer:

to enable intra-enterprise communication to conserve global address space

Question 4: Which statement about Cisco Discovery Protocol is true?

It is Cisco-proprietary Protocol It can discover information from routers, firewalls and switches It runs on the network layer It runs on the physical layer and the data link layer.

Answer:

It is Cisco-proprietary Protocol

Question 5: Which function does traffic shaping perform?

It buffers traffic without queuing it It queues traffic without buffering it It drops packets to control the output rate It buffers and queues excess packets

Answer:

It buffers and queues excess packets Question 6: Which networking technology is currently recognized as the standard for computer networking?System network architecture Transmission control protocol/Internet protocol Open system Interconnect Open network architecture

Answer:

Transmission control protocol/Internet protocol

Question 7: What does traffic shaping do to reduce congestion in a network?

buffers and queues packets buffers without queuing packets queues without buffering packets drops packets

Answer:

buffers and queues packets Question 8: Which RFC was created to alleviate the depletion of IPv4 public addresses?

RFC 4193

RFC 1519

RFC 1518

RFC 1918

Answer:

RFC 1918

Question 9: Which function does traffic shaping perform?

It buffers and queues excess packets It buffers traffic without queuing it It queues traffic without buffering it It drops packets to control the output rate

Answer:

It buffers and queues excess packets Question 10: Which statements correctly describe steps in the OSI data encapsulation process?(Choose two) The transport layer divides a data stream into segments and may add reliability and flow control information.The data link layer adds physical source and destination addresses and an FCS to the segment.Packets are created when the network layer encapsulates a frame with source and destination host addresses and protocol-related control information.Packets are created when the network layer adds Layer 3 addresses and control information to a segment.The presentation layer translates bits into voltages for transmission across the physical link.

Answer:

The transport layer divides a data stream into segments and may add reliability and flow control information.Packets are created when the network layer adds Layer 3 addresses and control information to a segment.

Question 11: Which command can you use to set the hostname on a switch?

switch-mdf-c1(config)#hostname switch-mdf1 switch-mdf-c1>hostname switch-mdf1 switch-mdf-c1#hostname switch-mdf1 switch-mdf-c1(config-if)#hostname switch-mdf1

Answer:

switch-mdf-c1(config)#hostname switch-mdf1 Question 12: Which three encapsulation layers in the OSI model are combined into the TCP/IP application layer? (Choose three) Session Transport Presentation Application Data-link Network

Answer:

Session Presentation Application

Question 13: Which two statements about fiber cable are true? (Choose two)

Single-mode fiber supports SC and LC connectors only Single-mode cable is most appropriate for installations longer 10 km Fiber cable is relatively inexpensive and supports a higher data rate than coaxial cable Multimode cable supports speeds between 100 Mbps and 100 Gbps Multimode cable supports speeds between 100 Mbps and 9.92 Gbps

Answer:

Single-mode cable is most appropriate for installations longer 10 km Multimode cable supports speeds between 100 Mbps and 100 Gbps Question 14: Which two statements are true for multicast MAC address directions?01:00:5E:xx:xx:xx one to one 01 00 xx xxxxxxx 02 xx xxxxxxx one to many

Answer:

01:00:5E:xx:xx:xx one to many
