Latest and Most Accurate CompTIA N10-006 Dumps Exam Questions and Answers:
A company wants to create highly available datacenters. Which of the following will allow the company to continue to maintain an Internet presence at all sites in the event that a WAN circuit at one site goes down?
A. Load balancer
A collection of networks that fall within the same administrative domain is called an autonomous system (AS). In this question, each datacenter will be an autonomous system.
The routers within an AS use an interior gateway protocol, such as the Routing Information Protocol (RIP) or the Open Shortest Path First (OSPF) protocol, to exchange routing information among themselves. At the edges of an AS are routers that communicate with the other AS’s on the Internet, using an exterior gateway protocol such as the Border Gateway Protocol (BGP).
If a WAN link goes down, BGP will route datathrough another WAN link if redundant WAN links are available.
An organization requires a second technician to verify changes before applying them to network devices. When checking the configuration of a network device, a technician determines that a coworker has improperly configured the AS number on the device. This would result in which of the following?
A. The OSPF not-so-stubby area is misconfigured
B. Reduced wireless network coverage
C. Spanning tree ports in flooding mode
D. BGP routing issues
Which of the following network devices use ACLs to prevent unauthorized access into company systems?
C. Content filter
D. Load balancer
A firewall is a system designed to prevent unauthorized access to or from a private network. Firewalls arefrequently used to prevent unauthorized Internet users from accessing privatenetworks connected to the Internet, especially intranets. Firewalls use ACLs (access control lists) to determine which traffic is allowed through the firewall. All traffic entering or leaving the intranet passes through the firewall, which examines each message and blocks or allows the message depending on rules specified in the ACL. The rules in the ACL specify which combinations of source IP address, destination address in IP port numbers are allowed.
Which of the following is used to define how much bandwidth can be used by various protocols on the network?
A. Traffic shaping
B. High availability
C. Load balancing
D. Fault tolerance
If a network connection becomes saturated to the point where there is a significant level of contention, network latency can rise substantially.
Traffic shaping is used to control the bandwidth used by network traffic. In a corporate environment, business-related traffic may be given priority over other traffic. Traffic can be prioritized based on the ports used by the application sending the traffic. Delayed traffic is stored in a buffer until the higher priority traffic has been sent.
Which of the following is used to authenticate remote workers who connect from offsite? (Select TWO).
B. VTP trunking
C. Virtual PBX
D: A RADIUS (Remote Authentication Dial-in User Service)server is a server with a database of user accounts and passwords used as a central authentication database for users requiring network access. RADIUS servers are commonly used by ISP’s to authenticate their customer’s Internet connections.
Remote users connect to one or more Remote Access Servers. The remote access servers then forward the authentication requests to the central RADIUS server.
E: 802.1X is an IEEE Standard for Port-based Network Access Control (PNAC). It provides an authentication mechanism to devices wishing to attach to a network.
802.1X authentication involves three parties: a supplicant, an authenticator, and an authentication server. The supplicant is a client that wishes to attach to the network. The authenticator is a network device,such as an Ethernet switch, wireless access point or in this case, a remote access server and the authentication server is the RADIUS server.
Which of the following provides accounting, authorization, and authentication via a centralized privileged database, as well as, challenge/response and password encryption?
A. Multifactor authentication
D. Network access control
TACACS+ (Terminal Access Controller Access-Control System Plus) is aprotocol that handles authentication, authorization, and accounting (AAA) services. Similar to RADIUS, TACACS+ is a centralized authentication solution used to provide access to network resources. TACACS+ separates the authentication, authorization, and accounting services enabling you to host each service on a separate server if required.
