Optimization Flashcards
Your network conducts training sessions for high-profile clients. As part of the training, clients connect to get
a video feed of the instructor and other class activities. You want to make sure that video traffic related to
the training is not delayed on the network.
Which solution should you implement?
Ethernet bonding
Caching engine
Qo5
Load balancing

Angela is the network administrator for a rapidly growing company with a IOOBaseT network. Users have
recently complained about slow file transfers. In a check of network traffic, Angela discovers a high number
of collisions.
Which connectivity device would best reduce the number of collisions and provide for future growth?
Switch Bridge Router Gateway Hub
Switch
A switch receives a frame addressed to the MAC address FF:FF:FF:FF:FF:FF. What will the switch do with the
frame?
Forward it out the port to the device with that MAC address.
Send it out all ports except for the port it was received on.
Process the frame and respond back to the sending device.
Drop the frame.
Send it out all ports except for the port it was received on.
You manage a network that uses multiple switches. You want to provide multiple paths between switches so
that if one link goes down, an alternate path is available.
Which feature should your switch support?
PoE Trunking Spanning tree Mirroring OSPF
Spanning tree
Which of the following devices is capable of performing routing of IP packets at wire speeds using an ASIC module instead of the CPU or software?
Firewall
Proxy server
Layer 3 switch
IDS
Layer 3 switch
You manage a single subnet with three switches. The switches are connected to provide redundant paths
between the switches.
Which feature prevents switching loops and ensures there is only a single active path between any two
switches?
Spanning tree PoE Bonding 802.1x Trunking
Spanning tree
You have a Web site that uses multiple servers for different types of transactions. For example, one server is
responsible for static Web content, while another is responsible for secure transactions.
You would like to implement a device to speed up access to your Web content. The device should be able to
distribute requests between the various Web servers using specialized hardware and not just a software
configuration. In addition, SSL sessions should use the hardware components in the device to create the SSL
sessions.
Which type of device should you choose?
Bandwidth shaper
Proxy server
Content switch
Circuit-level gateway
Content switch
What is the purpose of using Ethernet bonding? (Select two.)
Provides a failover solution for network adapters
Provides increased bus speeds
Increases read and write operations between the system bus and network adapters
Increases network performance
Enables Dual Remote Access (DRA) over a WAN link
Provides a failover solution for network adapters
Increases network performance
You have a network server with two network interface cards. You want both network adapters to be used at
the same time to connect to the same network to double the amount of data the server can send.
Which feature would you use?
Ethernet bonding
Mirroring
Full-duplex
Spanning tree
Ethernet bonding
You have a Web server on your network that hosts the public Web site for your company. You want to make sure that a failure of the NIC in the server does not prevent the Web site from being accessible on the Internet. Which solution should you implement? Spanning tree Traffic shaping Ethernet bonding Qo5
Ethernet bonding
QoS provides which of the following on a network?
Distributes client requests between multiple devices
Provides fault tolerance for network devices
Allows network services to handle more client requests
Reduces latency of time-sensitive traffic
Reduces latency of time-sensitive traffic
You have a Web server on your network that hosts the public Web site for your company. You want to make sure that the Web site will continue to be available even if a NIC, hard drive, or other problem prevents the server from responding. Which solution should you implement? NIC teaming Traffic shaping QoS Load balancing
Load balancing
You want to reduce collisions by creating separate collision domains and virtual LANs. Which of the following
devices should you choose?
Bridge
Switch
Active hub
Router
Switch
Which of the following features dynamically places switch ports in blocking or forwarding states?
Spanning tree
PoE
Mirroring
Trunking
Spanning tree
You manage a server that runs your company Web site. The Web server has reached its capacity, and the
number of client requests is greater than the server can handle.
You would like to find a solution so that static Web content can be offloaded to a different server, while the
Web server continues to process dynamic content.
Which solution should you implement?
Traffic shaper
Proxy server
Qo5
