PPTP uses a TCP control channel and a GRE tunnel to encapsulate PPP packets L2TP: In computer networking, Layer 2 Tunneling Protocol is a tunneling protocol used to support virtual private networks or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself.
__________Layer of the OSI takes care of the compression and encryption. Physical Session Presentation Transport
Presentation layer, Layer 6, which is primarily responsible for managing protocol and architecture. ... Some functions of the presentation layer include character-code translation, data conversion, data encryption and decryption, and data translation.
What is the frame that is smaller than 64 bytes called? JUMBO RUNT TINY MICRO
RUNT In networks, a runt is a packet that is too small. For example, the Ethernet protocol requires that each packet be at least 64 bytes long. In Ethernet, which operates on the idea that two parties can attempt to get use of the line at the same time and sometimes do, runts are usually the fragments of packet collisions.
Which of the below is not a process in the DHCP DORA? Discover Offer Response Acknowledge
Response Discovery Offer Request Acknowledgement
You need to run four Ethernet network drops. Each drop is approximately 125 feet/46.33 meters. An interference exists along the path of each drop. You need to ensure that interference is reduced. Which cable type should you use? A. STP Cat5e B. UTPCat5e C. Cat3 D. UTPCat6
STP Cat5e Cat5e, is an improvement on Cat5 cabling. It was made to support 1000 Mbps "gigabit" speeds, so in theory, it's faster than Cat5. It it also cuts down on crosstalk, the interference you can sometimes get between wires inside the cable.
In the IP Sec the __________ generates encryption and authentication keys. SA AH ARP ESP
Security Associations (SA) provides the bundle of algorithms and data that provide the parameters necessary for AH and/or ESP operations. (ESP) Encapsulating Security Payloads
Which of the below modes are related to Fiber Optic Cable? Single Mode Multi Mode Fiber Mode RJ Mode
Single Mode Multi Mode
Which of these protocols is not a Network Layer Protocol? IP ICMP HTTP ARP
The Hypertext Transfer Protocol is an application protocol for distributed, collaborative, and hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. Standard port: 80
A user reports that she cannot connect to network resources from a computer on the company network. The user was able to connect to the network resources yesterday. You verify that the user's computer is properly physically connected to the network. You discover that the computer's IP address is 169.254.48.97. You need to restore access to network resources. What should you do next? A. Flush the cache on the DNS server. B. Reset the user's password on the server. C. Check your router's current routing tables. D. Verify that the DHCP service is available.
Verify that the DHCP service is available
Which of the below is a 64 bit Wireless Encryption Protocol? AES TKIP WPA 2 WEP
WEP Wired Equivalent Privacy (WEP), and its weaker security level is discussed here. Wired Equivalent Privacy (WEP) is a security protocol for wireless networks that encrypts transmitted data . ... (40-bit and 64-bit WEP encryption are the same thing — 40-bit devices can communicate with 64-bit devices.)
Service in Windows resolves NetBIOS names to IP addresses. WINS DHCP DNS ARP
WINS: Windows Internet Name Service is Microsoft's implementation of NetBIOS Name Service, a name server and service for NetBIOS computer names.
Which of the below two tools can be used to capture and analyze traffic? Wireshark Kiwi syslog dumpster diving tcpdump
Wireshark/tshark /dumpcap can use tcpdump filter syntax as capture filter. As tcpdump is available on most *NIX system I usually use tcpdump. Depending on the problem I sometimes use tcpdump to capture traffic and write it to a file, and then later use wireshark to analyze it.
After you configure an IP address and subnet mask on a Windows 7 PC, you want to check the configuration and confirm that the IP and subnet is configured, which of the below command is used. ifconfig traceroute ping ipconfig
ipconfig In computing, ipconfig in Microsoft Windows is a console application that displays all current TCP/IP network configuration values and can modify Dynamic Host Configuration Protocol and Domain Name System settings.
The ______________ command in Windows CLI will remove the IP address learnt from DHCP. ipconfig /renew ipconfig / release netstat / release ping -a
ipconfig / release First, ipconfig /release is executed to force the client to immediately give up its lease by sending the server a DHCP release notification which updates the server's status information and marks the old client's IP address as "available". Then, the command ipconfig /renew is executed to request a new IP address.
You are required to find the MAC address of you own computer. Which of the below command is used? ipconfig /all ipconfig -an netstat -an ipconfig
ipconfig /all Ipconfig (sometimes written as IPCONFIG) is a command line tool used to control the network connections on Windows NT/2000/XP machines. ... Ipconfig displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings.
Which of the below command will help remove IP address from CLI? ipconfig removeIP netdom netsh
netdom Netdom is a command-line tool that is built into Windows Server 2008 and Windows Server 2008 R2.
The ___________ command is used to check the connection status to and from your computer. netstat -an ping -t arp -a tcpdump
netstat -an However this can provide you with more information than you need. Therefore if you are looking for specific port then you can filter that information. For example to find a connection to web sites or other services using port 80 use this command: netstat -an | findstr :80 Will show all connections on port 80
PVCs are associated with Frame Relay, what does PVC stand for _________________________ Permanent Virtual Circuit Permanent Virtual Class Preferable Volunteer Circuit Passive Virtual Circuit
permanent virtual circuit (PVC) is a connection that is permanently established between two or more nodes in frame relay and asynchronous transfer mode (ATM) based networks. It enables the creation of a logical connection on top of a physical connection between nodes that communicate frequently or continuously.
