Networking Practice Test Flashcards
Cheryl is in charge of maintaining her company’s website accessibility. Upon inspection, she finds that too much traffic is being directed to one web server while other web servers are sitting idle. What internet appliance could Cheryl use to resolve this issue?
Explanation:
A load balancer is an internet appliance designed to spread requests over multiple servers to evenly distribute the demand and balance a system.
Which sets of connectors are used for twisted pair cabling?
RJ11 and RJ45 are used in twisted pair cabling, commonly for phone lines and ethernet, respectively.
What type of IP address is 192.168.15.211?
A private IPv4 address
IPv4 addresses follow the format of four decimal octets. IPv6 format is eight hexadecimal quartets. IP addresses that begin with 192.168 are in the RFC1918 set of private addresses.
William is publishing his company’s website to the internet and wants to ensure a secure connection. Which of these protocols should William use?
Hypertext Transfer Protocol Secure (HTTPS) is the secure version of the HTTP protocol. HTTPS is run on port 443.
Hannah’s new clothing business is experiencing rapid growth, and she has planned to open 300 new retail locations within the next 5 years. All of these locations will need multiple public IP addresses per store, but, currently, they only have four public addresses. She would like to implement a new scheme, where she would not have to worry about being limited by IP addresses in the foreseeable future. What addressing scheme would you recommend?
IPv6 addressing
Explanation:
The public IPv4 address space has been exhausted for quite some time now, meaning that all of these addresses have been purchased or allocated, usually by an Internet Service Provider (ISP). Many technical savvy companies have already begun the transition to using IPv6, which contains a possible 340 undecillion addresses, or 2 to the 128th power (yes, a lot of addresses). Many, if not all, ISPs have IPv6 enabled equipment already in operation.
David is installing a new Web server at the office, but doesn’t want DHCP giving it a new IP address every time he has to reboot it during maintenance. What kind of address should David assign to the new Web server?
Static addresses are those that are manually assigned and entered on a device. This will effectively disable DHCP. He should also reserve the IP address in the DHCP pool as good practice to prevent it from being leased to another device.
In a Windows environment, this protocol is often associated with Active Directory for central management of a user database. What is this protocol called?
LDAP (Lightweight Directory Access Protocol) often works in conjunction with Active Directory to provide user authentication and management in a network. It is the successor to the DAP (Directory Access Protocol).
Bob is implementing a new wireless network in his home office and needs assistance in selecting his equipment. He needs something that won’t interfere with his 2.4 GHz phones and that has speed that can reach at least 54 Mbps. Which wireless standard would you suggest to Bob?
802.11n is the only option listed that can operate at either 2.4 or 5 GHz and has a theoretical maximum speed of 600 Mbps; it would also provide the least amount of interference if using the 5 GHz band. 802.11b/g both operate at 2.4 GHz only which could possibly interfere with any other devices in that frequency.
Robert is able to configure port assignments through his switch. What type of switch is Robert using?
A managed switch is a device that the end-user is able to configure manually. Configurable aspects include port assignments, traffic management, and traffic monitoring. A managed switch also offers quality of service (QoS), redundancy, VLANs, and port mirroring.
In order for devices on our local home IPv4 network to communicate with other devices on the Internet, our SOHO router must perform what?
NAT (Network Address Translation) allows our private local network IPv4 addresses to be translated into a public IP address capable of connecting over the Internet. This can also be used with IPv6, due to security advantages, although it is less likely.
Gavin has been notified that a potential breach may have occurred through the use of a stolen employee login credential. He needs to look at past login information. Which server should Gavin access to find this information?
A syslog server is a central repository for system messages and data, including login events and errors.
Which Internet connection type is limited to an area near the central office and can make use of existing wiring infrastructure?
Digital Subscriber Line (DSL) is limited by the distance from the central office for communication and can make use of existing phone lines already in place at your home or business.
Peggy needs to implement a spam management system that authenticates using encryption and a public-private key pair as well as the IP address. Which spam management tool would be the best option to fulfill the requirements?
Domain-based Message Authentication, Reporting, and Conformance (DMARC) would be the best option to fulfill all of the spam management requirements. DMARC combines both DomainKeys Identified Mail (DKIM) and Sender Policy Framework (SPF) in a single framework.
Sophie’s company requires the fastest possible internet connection publicly available. Her supervisor has asked Sophie to recommend an internet connection type by dragging and dropping one of the following into a space in an email form. Which type of internet connection should Sophie drag to this space?
A fiber internet connection uses light to send data and currently offers the fastest connection speeds.
A network that connects two states would commonly be known as a ____ network?
Wide Area Networks, also known as WAN’s, are networks that are connected across long distances, such as state to state or coast to coast.
