Version: 15.0
Question: 21

When convergence on a routed network occurs, which of the following is true?

A. All routers are using hop count as the metric
B. Allrouters have the same routing table
C. All routers learn the route to all connected networks
D. All routers use route summarization

Answer: C

Explanation:
Routers exchange routing topology information with each other by using a routing protocol. Whenall routers have exchanged routing information with all other routers within a network, the routers are said to have converged. In other words: In a converged network all routers “agree” on what the network topology looks like.

Question: 22

An administrator has a virtualization environment that includes a vSAN and iSCSI switching. Which of the following actions could the administrator take to improve the performance of data transfers over iSCSI switches?

A. The administrator should configure the switch ports to auto-negotiate the proper Ethernet settings.
B. The administrator should configure each vSAN participant to have its own VLAN.
C. The administrator should connect the iSCSI switches to each other over inter-switch links (ISL).
D. The administrator should set the MTU to 9000 on the each of the participants in the vSAN.

Answer: D

Explanation:
When using an iSCSI SAN (with iSCSI switching), we can improve network performance by enabling ‘jumbo frames’. A jumbo frame is a frame with an MTU of more than 1500. By setting the MTU to 9000, there will be fewer but larger frames going over the network. Enabling jumbo frames can improve network performance by making data transmissions more efficient. The CPUs on switches and routers can only processone frame at a time. By putting a larger payload into each frame, the CPUs have fewer frames to process.

Question: 23

Which of the following network devices use ACLs to prevent unauthorized access into company systems?

A. IDS
B. Firewall
C. Content filter
D. Load balancer

Answer: B

Explanation:
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.

Question: 24

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

Answer: A

Explanation:
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.

Question: 25

Which of the following is used to authenticate remote workers who connect from offsite? (Select TWO).

A. OSPF
B. VTP trunking
C. Virtual PBX
D. RADIUS
E. 802.1x

Answer: D,E

Explanation:
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.

Question: 26

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
B. ISAKMP
C. TACACS+
D. Network access control

Answer: C
