Network Engineering Quiz

Users are reporting longer delays in authentication and in accessing network resources during certain time periods of the week. What kind of information should network engineers check to find out if this situation is part of a normal network behavior?

• syslog records and messages

• the network performance baseline

• debug output and packet captures

• network configuration files

How does the service password-encryption command enhance password security on Cisco routers and switches?

• It requires encrypted passwords to be used when connecting remotely to a router or switch with Telnet.

• It encrypts passwords that are stored in router or switch configuration files.

A network administrator wants to have the same network mask for all networks at a particular small site. The site has the following networks and number of devices: IP phones - 22 addresses, PCs - 20 addresses needed, Printers - 2 addresses needed, Scanners - 2 addresses needed. The network administrator has deemed that 192.168.10.0/24 is to be the network used at this site. Which single subnet mask would make the most efficient use of the available addresses to use for the four subnetworks?

• 255.255.255.240

• 255.255.255.252

• • 255.255.255.224

• 255.255.255.0

• 255.255.255.248

What characteristic describes identity theft?

• the use of stolen credentials to access private data

• software on a router that filters traffic based on IP addresses or applications

• software that identifies fast-spreading threats

• a tunneling protocol that provides remote users with secure access into the network of an organization

A network administrator is adding a new LAN to a branch office. The new LAN must support 200 connected devices. What is the smallest network mask that the network administrator can use for the new network?

• 255.255.255.0

• 255.255.255.248

• 255.255.255.224
