Chapter 2 - Domian 2 Network Installation and Configuration Flashcards
Why would you want to create a static route in a routing table?
page 61
When there is only one main location to access or send files, for example printers, video, etc.
What is a NAT & what is it used for?
page 61
Network Address Translation
- translates one set of IP addresses to another set of IP addresses.
- Often used between private network & the Internet.
What is PAT & what is it used for?
page 61
Port Address Translation
When 2 or more PCs share one external address to keep their network communication channels separate.
`PAT appends it by using a specific port number.
What are managed & unmanaged devices?
page 63
- Unmanaged devices - devices that require no configuration, they configure themselves.
- Managed devices - required specific configuration.
What are the five Interface Configurations?
page 63
Full Duplex - device that can send & receive at same time.
Half Duplex - device that can only send or receive at one time.
Port Speeds - the speed at which most NICs, Switches, ports can use (10Mbps, 100Mbps, 1000Mbps…)
IP Addressing - commonly used IPv4
MAC Addressing - 48-bit hexadecimal, usually applied where the host PC are connected to switches.
What is VTP & what does it do for you?
page 65
VLAN Trunking Protocol
A protocol that is proprietary to Cisco & allows you to create a switch with the role of “Server” that you can configure with your VLAN info.
How does QoS make use of the bandwidth more efficient & effective?
page 66
- Network technique that divides traffic into categories based on the protocol of the traffic.
- Allows for prioritization of each category.
- Priority traffic get preference than general traffic.
How is Port Mirroring accomplished?
page 66
- Monitoring all traffic that VLAN separates for security reasons.
- Gets copy of network packets from one switch port, sent to another switch port.
- Uses Intrusion Detection System/Intrusion Prevention System (IDS/IPS) to do the monitoring.
Why should you take into account of the distance between client & Wireless Access Points (WAP)?
page 67
Could affect the power of intended signal & make interference from other signals more pronounced.
What are some cause of Interference on a Wireless network?
page 68
- Bluetooth, keyboards, mice
- Cell phones
- Microwave ovens
- Electric motors
- Mundane appliances such as refrigerators.
What are channels & which are commonly used and why?
page 68
A combination of frequencies (typically the 2.4GHZ or 5GHz band) that can be used by the end user.
- WAPs & clients must be on the same channel
- Most likely use channel 1, 6 or 11, these channels are non-overlapping, therefore leas likely to interfere with each other.
What types of modulation do each wireless standard use?
page 69
- 11a - OFDM (Orthogonal Frequency Division Multiplex)
- 11b - DSSS (Direct Sequence Spread Spectrum)
- 11g - OFDM/DSSS
- 11n - OFDM/DSSS
What types of devices should have static IP addresses?
page 70
- Servers
- Network printers
- Plotters
- Router interfaces
- Any device that needs to be statically configured so their addresses do not change
What are Reservations?
page 71
- DHCP give Random addresses
- Clients that receive the same address based on their MAC Address
How should you manage your scopes?
page 71
- Scopes are a range of addresses that can be assigned to clients.
- Scopes should be based on IP subnets.
- Scope addresses should not overlap other addresses in other scopes to prevent IP address conflicts.
