(a) is a set of mechanisms that try to guarantee timely delivery or minimal delay of important or time-sensitive communications.
This is a subnetwork placed between the LAN and untrusted networks, such as the internet. External network nodes can access only what you choose to expose in the screened subnet. The rest of the network is protected by firewalls. It was previously known as a demilitarized zone (DMZ).
Screened subnet
VLAN
Spanning tree
Traffic shaper
What is NOT a goal of network optimization?
Fault tolerance
High availability
Uptime
Monetization
(a) might lead to out of date information.
(a) allows a switch to maintain multiple paths between switches within a subnet. It runs on each switch and is used to select a single path between any two switches
This logically groups two or more physical connections to the same network. Data is divided and sent on multiple interfaces, effectively increasing the speed at which the device can send and receive on the network.
Load balancing
NIC Teaming
Quality of Service (QoS)
Port Aggregation (PAgP)
What is the purpose of using Ethernet bonding (aka NIC or adapter teaming)? (Select two.)
Provides increased bus speeds
Increases network performance
Provides a failover solution for network adapters
Enables Dual Remote Access (DRA) over a WAN link
An application-specific integrated circuit is used by switches to optimize network performance by performing switching operations in hardware rather than using the CPU and software
True
False
Which of the following statements about Differentiated Services Code Point (DSCP) are true? (Select two.)
Classification occurs at Layer 1
The network switch assigns priority values
It uses the DiffServ field to add precedence values
Classification occurs at Layer 3
0
Background
2
Excellent effort
4
Video (< 100ms latency)
5
Voice (< 10ms latency)
7
Network control
(a) is the first step in troubleshooting.
When troubleshooting, what step comes after testing your theory?
Document findings, actions, and outcomes
Implement the solution or escalate as necessary
Establish a plan of action
Establish a theory of probable cause
Which is NOT a troubleshooting utility?
Dig
Traceroute / Tracert
Netstat
Shovel
(a) is insecure. It's replacement, (b) is secure.
(a) prints the contents of network packets.
If you wanted to create a dashboard that displayed network speed across different interfaces, which software tool would you use?
Iperf
Netstat
Ping
Traceroute
What software tool can be used as a protocol analyzer?
Wireshark
Dig
Netstat
Nmap
What TCP/IP utility produces the output shown in the image to the left?
ping
netstat -a
ipconfig
arp -a
With Wireshark, you've used a filter to capture only the desired packet types. Using the information shown in the image to the left, which of the following BEST describes the effects of using the host 192.168.0.34 filter?
Only packets with 192.168.0.34 in the destination address are captured
Only packets with 192.168.0.34 in the source address are captured
Only packets with 192.168.0.34 in either the source or destination address are captured
Only packets on the 192.168.0.34 network are captured.
