Here are some free Cisco certification exam practice questions to help you be ready for total success on exam day!??? Answers are at the bottom of the page.? Enjoy!


CCNA Certification And CCENT Certification:


You want to hardcode the first 12 ports on a Cisco switch to all run at 100 MBPS and full-duplex. What single command will allow you to do this?


CCNA Security Certification CCNP ISCW Exam:


What's the difference between stateful and stateless packet filtering?


CCNP Certification BSCI Exam:


Which of the following does NOT have to match between prospective OSPF neighbors?


A. Process ID


B. Hello timer


C. Dead timer


D. Stub flag setting


CCNP Certification BCMSN Exam:


Which of the following describes the default setting for DHCP Snooping?


A. It's off.


B. It's on.


C. When it's active, all interfaces are untrusted.


D. When it's active, all interfaces are trusted.


E. When it's active, trunking interfaces are trusted and all others are untrusted.


CCNP ONT Exam:


What is the full command to configure cRTP on the following interface?


R1(config)#int serial0


R1(config-if)#encap frame


R1(config-if)#


Here are the answers!


CCNA CCENT:? Answer: First Anthony Martial Jersey , go into interface range configuration mode with the interface range command:


SW1(config)#interface range fast 01 - 12


SW1(config-if-range)#


The commands you enter at this point will be added to all interfaces in that range. You can enter the speed 100 and duplex full commands here to have all interfaces in that range set to those values.


CCNA Security ISCW Exam:? Answer: Stateless packet filtering is generally referred to simply as packet filtering. Packet filtering works much like an ACL. It's common to filter packets on one or more of the following:


1. Source IP address or port number


2. Destination IP address or port number


3. Protocol


Sounds great, right? There are some problems with this technique. Packet filtering only considers the values in the ACL - there's no attempt to determine if this packet is part of an already-existing connection, or attempting to create one. With protocols that use random port numbers at times - FTP, for example - there can be some real problems establishing a connection.


Stateful packet filtering does monitor the connection state Angel Gomes Jersey , and that's particularly important when it comes to preventing TCP attacks. A stateful firewall will not only monitor the state of the TCP connection, but also the sequence numbers. Stateful firewalls accomplish this by keeping a session table, or state table.


BSCI:? Answer: D. Two OSPF routers can be using different process numbers and still become neighbors.


BCMSN:? Answer: A, C. DHCP Snooping is off by default Andreas Pereira Jersey , and when you enable it, all interfaces are untrusted.


ONT:? Answer: To configure RTP Header Compression on this interface, enter the ip rtp header-compression command. In this example, IOS Help displays our options with this command.


R3(config)#int s000


R3(config-if)#ip rtp header-compression ?


ietf-format Compressing using IETF format


iphc-format Compress using IPHC format


passive Compress only for destinations which send compressed headers


R3(config-if)#ip rtp header-compression

CREATE A MOTIVATIONAL CLIMATE: Create a climate where others find long-term motivation. Long term motivation comes from a positive work environment, and positive reinforcement. Usually long-term motivation is impossible without short-term motivation. Short-term motivation comes from the staff working together, learning from each other, and giving as well as receiving constant feedback to each other. Short-term motivation builds self motivation. Self motivation comes from daily reinforcements. Little reinforcements such as good food in the cafe
