Checkpoint Exam: Building and Securing a Small Network 2026 2

A user reports a lack of network connectivity. The technician takes control of the user machine and attempts to ping other computers on the network and these pings fail. The technician pings the default gateway and that also fails. What can be determined for sure by the results of these tests?

• The NIC in the PC is bad.

• The TCP/IP protocol is not enabled.

• The router that is attached to the same network as the workstation is down.

• Nothing can be determined for sure at this point.

What is an accurate description of redundancy?

• designing a network to use multiple virtual devices to ensure that all traffic uses the best path through the internetwork

• configuring a switch with proper security to ensure that all traffic forwarded through an interface is filtered

• designing a network to use multiple paths between switches to ensure there is no single point of failure

• configuring a router with a complete MAC address database to ensure that all frames can be forwarded to the correct destination

A ping fails when performed from router R1 to directly connected router R2. The network administrator then proceeds to issue the show cdp neighbors command. Why would the network administrator issue this command if the ping failed between the two routers?

• The network administrator wants to verify Layer 2 connectivity.

• The network administrator wants to verify the IP address configured on router R2.

• The network administrator suspects a virus because the ping command did not work.

• The network administrator wants to determine if connectivity can be established from a non-directly connected network.

What information about a Cisco router can be verified using the show version command?

• the value of the configuration register

• the administrative distance used to reach networks

• the routing protocol version that is enabled

• the operational status of serial interfaces

A network administrator is upgrading a small business network to give high priority to real-time applications traffic. What two types of network services is the network administrator trying to accommodate?

• Instant messaging

• SNMP

• Voice

• Video

• FTP

Which statement is true about Cisco IOS ping indicators?

• '.' indicates that the ping was successful but the response time was longer than normal.

• 'U' may indicate that a router along the path did not contain a route to the destination address and that the ping was unsuccessful.

• A combination of '.' and '!' indicates that a router along the path did not have a route to the destination address and responded with an ICMP unreachable message.

• '!' indicates that the ping was unsuccessful and that the device may have issues finding a DNS server.

What is the purpose of a small company using a protocol analyzer utility to capture network traffic on the network segments where the company is considering a network upgrade?

• to document and analyze network traffic requirements on each network segment

• to identify the source and destination of local network traffic

• to capture the Internet connection bandwidth requirement

• to establish a baseline for security analysis after the network is upgraded

A network engineer is troubleshooting connectivity issues among interconnected Cisco routers and switches. Which command should the engineer use to find the IP address information, host name, and IOS version of neighboring network devices?

• show version

• show cdp neighbors detail

• show interfaces

• show ip route

Users are complaining that they are unable to browse certain websites on the Internet. An administrator can successfully ping a web server via its IP address, but cannot browse to the domain name of the website. Which troubleshooting tool would be most useful in determining where the problem is?

• netstat

• nslookup

• ipconfig

• tracert

A technician is to document the current configurations of all network devices in a college, including those in off-site buildings. Which protocol would be best to use to securely access the network devices?

• HTTP

• FTP

• Telnet

• SSH
