1. A user in a large office calls technical support to complain that a PC has suddenly lost connectivity to the network. The technician asks the caller to talk to nearby users to see if other machines are affected. The caller reports that several immediate neighbors in the same department have a similar problem and that they cannot ping each other. Those who are seated in other departments have connectivity. What should the technician check as the first step in troubleshooting the issue?

The trunks between switches in the wiring closet

the cable that connects the PC of the caller to the network jack

the cable connection between a PC and a network outlet that is used by a neighbor

the power outlet to the PC that is used by the caller

the status of the departmental workgroup switch in the wiring closet

2. Users report that the new web site http://www.company1.biz cannot be accessed. The helpdesk technician checks and verifies that the web site can be accessed with http://www.company1.biz:90. Which layer in the TCP/IP model is involved in troubleshooting this issue?

internet

network access

application

transport

1. When should a network performance baseline be measured?

when a denial of service attack to the network is detected and blocked

during normal work hours of an organization

immediately after the main network devices restarted

after normal work hours to reduce possible interruptions

2. After which step in the network troubleshooting process would one of the layered troubleshooting methods be used?

narrowing the scope

After which step in the network troubleshooting process would one of the layered troubleshooting methods be used?

gathering symptoms from suspect devices

determining ownership

1. Fill in the blank.

In an IoT implementation, devices will be connected to a _converged _ network to share the same infrastructure and to facilitate communications, analytics, and management.

2. The exhibit is not required to answer the question. The exhibit shows a fog covering trees on the side of a mountain.What statement describes Fog computing?

It utilizes a centralized computing infrastructure that stores and manipulates big data in one very secure data center.

It creates a distributed computing infrastructure that provides services close to the network edge.

It requires Cloud computing services to support non-IP enabled sensors and controllers.

It supports larger networks than Cloud computing does.

1. When QoS is implemented in a converged network, which two factors can be controlled to improve network performance for real-time traffic? (Choose two.)

jitter

packet addressing

packet routing

delay

link speed

2. An administrator has mastered the use of access control lists (ACLs) and wants to deploy QoS by defining different traffic classes through the use of ACLs. Which queuing method provides this functionality?

FIFO

CBWFQ

WFQ

FCFS

1. Which protocol defines port-based authentication to restrict unauthorized hosts from connecting to the LAN through publicly accessible switch ports?

TACACS+

SSH

RADIUS

802.1x

2. What device is considered a supplicant during the 802.1X authentication process?

the authentication server that is performing client authentication

the client that is requesting authentication

the switch that is controlling network access

the router that is serving as the default gateway

1. Which range represents all the IP addresses that are affected when network 10.120.160.0 with a wildcard mask of 0.0.7.255 is used in an ACE?

10.120.160.0 to 10.120.191.255

10.120.160.0 to 10.127.255.255

10.120.160.0 to 10.120.168.0

10.120.160.0 to 10.120.167.255

2. Refer to the exhibit. The Ipv6 access list LIMITED_ACCESS is applied on the S0/0/0 interface of R1 in the inbound direction. Which Ipv6 packets from the ISP will be dropped by the ACL on R1?

neighbor advertisements that are received from the ISP router

HTTPS packets to PC1

packets that are destined to PC1 on port 80

ICMPv6 packets that are destined to PC1

1. Which two scenarios are examples of remote access VPNs? (Choose two.)

All users at a large branch office can access company resources through a single VPN connection.

A mobile sales agent is connecting to the company network via the Internet connection at a hotel.

A small branch office with three employees has a Cisco ASA that is used to create a VPN connection to the HQ.
