Study Notes
N10-008 Exam Questions - Study Notes
-
WiFi Performance Improvement: A systems administrator needs to improve Wi-Fi performance in a dense office building. With a mix of 2.4 GHz and 5 GHz devices, selecting 802.11ax is the best option for latest standard.
-
MAC Spoofing Detection: Internet Control Message Protocol (ICMP), Reverse Address Resolution Protocol (RARP), Dynamic Host Configuration Protocol (DHCP), and Internet Message Access Protocol (IMAP) are protocols used in networking. Reverse Address Resolution Protocol (ARP) is best for detecting MAC spoofing attacks.
-
Jitter Troubleshooting: A technician troubleshooting high jitter on a wireless network, with variations in latency using ping, should utilize a spectrum analyzer.
-
Wireless Connectivity Issues: Wireless users reporting intermittent internet connectivity with web authentication requiring reconnection, the cause is likely a session timeout configuration on the captive portal's settings.
-
Network Attacks: Tailgating is a security attack that involves physically following someone through a secured location. A network administrator prevented this security attack by stopping the unknown person and directing the person to security.
-
Wireless Network Setup: A wireless network setup simulation involves configuring three Access Points (APs) and one switch. The SSIDs should be "CorpNet" using the key "S3cr3t!". The wireless signals shouldn't interfere, the subnet should support a maximum of 30 connected devices, and the APs should only support TKIP clients at maximum speed for efficient setup.
-
CRC Errors: CRC errors during network communication indicates a problem on the Layer 2 of the OSI model which is often related to cabling.
-
VM Performance Issues: A sudden increase in 100 VM users caused performance issues. Metrics like CPU usage and memory will provide an accurate analysis of the underlying performance issues.
-
DHCP Exhaustion: When DHCP scope is exhausted, the administrator should reduce the lease time to avoid creating a new DHCP pool.
-
IPv6 and MAC Addresses: The switch feature MOST likely used to assist in scripting to log IPv6 and MAC addresses on a network segment is Neighbor Discovery Protocol (NDP).
-
DNS Records: A CNAME record in DNS acts as an alias for another record.
-
Network Connectivity: Troubleshooting internet connectivity issues in a new building that's connected to the LAN via fiber optic cable, the administrator should correct the DNS server entries in the DHCP scope to resolve the internet access issue.
-
Fiber Optic Cable Issues: A fiber optic cable connection problem was most likely caused by reversed TX/RX (transmit/receive) connections.
-
Finding Network Devices: Using the MAC table on a network switch is the BEST way for a technician to locate a device's network port.
-
Server Redundancy: Network Interface Card (NIC) teaming provides redundancy on a file server to ensure continued connection to the LAN in case of a port failure on a switch.
-
Content Delivery Networks: Content Delivery Networks (CDNs) are a technology that help optimize speeds and reduce latency for global content distribution.
-
Network Troubleshooting First Steps: Asking users about the specific changes made to the network is the recommended FIRST step in troubleshooting a network issue.
-
Cable Crossover: Using MDIX on the switch can resolve the cable crossover issue with vendor certified cables.
-
Network Monitoring Tool: IP scanner is the best network tool for finding devices on a network.
-
Wireless Network Channel Configuration: The technician should use 5GHz for configuring high density wireless networks to help reduce interference. A 5GHz network will allow for more channels to be used.
-
Network Switch Configuration: Configuring DHCP snooping on a switch in a public location can help prevent unintended network connections.
-
Vulnerability Tracking Tools: Common Vulnerabilities and Exposures (CVE) is used to track various types of known vulnerabilities.
-
Password Policies Two-factor authentication and complex passwords are recommended policies to mitigate brute-force password attacks.
-
Network Bandwidth Increase Using Multipathing, NIC teaming, Load Balancing, or Clustering on the server is best way to increase server bandwidth. This is achieved by connecting two network cables on the switch stack and ensuring correct configuration on the switch interfaces.
-
Network Device Configuration Commands: Validating network settings on a Linux device to match the 192.168.0.0/20 network block can be accomplished by using the 'ifconfig' or 'ip' command to get a detailed network configuration.
-
Biggest MTU for an Ethernet Frame: The biggest MTU for a standard Ethernet frame is 1500.
-
Command Line Networking Tools: The command-line tool 'netstat' shows the status of network connections and processes.
-
Troubleshooting Network Errors: Checking for errors on a network can include verifying the cable (by replacing cables), the switch (by verifying its functions), and the device (by confirming it is properly configured).
-
Network Troubleshooting: Using a bottom-up approach will help in efficiently troubleshooting network issues which starts from basic connectivity checks to more complex issues, such as checking for a rogue DHCP server or a misconfigured subnet mask.
