Clients receive IP address assignments from a rogue DHCP server. Requiring the users to switch to the 5 GHz band for streaming media is inconvenient and will result in fewer users accessing these services. Configure the security mode to WPA Personal TKIP/AES for one network and WPA2 Personal AES for the other network. Which solution is the best method to enhance the performance of the wireless network? 7. H1 can only ping H2, H3, and the Fa0/0 interface of router R1. Explanation: Splitting the wireless traffic between the 802.11n 2.4 GHz band and the 5 GHz band will allow for the 802.11n to use the two bands as two separate wireless networks to help manage the traffic, thus improving wireless performance. After a user is authenticated through AAA, authorization services determine which resources the user can access and which operations the user is allowed to perform. CAPWAP is also responsible for the encapsulation and forwarding of WLAN client traffic between an AP and a WLC. The maximum number of MAC addresses supported is 50. 143. 193. The only users that can switch to the 5 GHz band will be those with the latest wireless NICs, which will reduce usage. A technician is troubleshooting a slow WLAN that consists of 802.11b and 802.11g devices . 70. It provides high speed connections over copper wires. What type of Layer 2 encapsulation will be used for RtrA connection D if it is left to the default and the router is a Cisco router? 30. 167. 160. What is a possible cause of this problem? When testing the connectivity, a technician finds that these PCs can access local network resources but not the Internet resources. (Choose two.). 18. 33. Which access control component, implementation, or protocol controls who is permitted to access a network? Pls, answered it. What are two important business policy issues that should be addressed when using the Internet for this purpose? ASDM signed-image support in 9.14(4.14)/7.18(1.152) and laterThe ASA now validates whether the ASDM image is a Cisco digitally signed image.If you try to run an older ASDM image with an ASA version with this fix, ASDM will be blocked and the message %ERROR: Signature not valid for file disk0:/ will be displayed at the ASA CLI. -Ensure that the laptop antenna is attached. Depending on the configured Layer 2 protocol, data is transmitted across two or more channels via the use of time slots. Refer to the exhibit. -Ensure that the NIC is configured for the proper frequency. The passive-interface command has not been issued on interface serial 0/1/0. 223. Which three statements are true about PPP? VPP Troubleshooting - Various tips/tricks for commonly seen issues, The VPP API - design and implementation of the VPP API, API Change Process - Change your production-grade APIs in a compatible way without inhibiting innovation. Which type of wireless network is suitable for national and global communications? 175. Perform the tasks in the activity instructions and then answer the question.Which event will take place if there is a port security violation on switch S1 interface Fa0/1, I attach the screenshoot of the question 75. 60. Introduction To N-tuple Classifiers - An explanation of classifiers and how to create classifier tables and sessions. A new 802.11n/ac dual-band router has been deployed on the network to replace the old 802.11g router. 172. 37. (Choose three. (Choose two.). 209. What is the function of a QoS trust boundary? What network monitoring tool copies traffic moving through one switch port, and sends the copied traffic to another switch port for analysis? What are the two methods that are used by a wireless NIC to discover an AP? Which connection type should be selected? 200. 194. wireless client operating system password. Which wireless network topology would be used by network engineers to provide a wireless network for an entire college building? there are 2 ways of doing this, For this you need to enable http server on your ASA and you need to know the credentials used to access asa via asdm (default is no username no password), asa(config)# crypto key generate rsa modulus 1024, Note: This is for creating keys because we communicate with asa via https, if you have ssh access you probably have these keys, Once you have enabled http server on asa go to your browser and give the following in the url field, https:///capture//pcap, if it is in multiple context mode you have to specify the context, https:///capture///pcap, After you enter this you will be prompted for username password and once you enter that the captures are stored on your PC and you can open them in a packet anaylser tool, As metioned before in some cases you might need to capture packets on devices directly connected to asa and in most cases it is a switch connected to ASA and in such cases you can also span the switchport to collect captures, Here is a link which will help you setup a span on your catalyst switch, http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml#config, Once done always make sure that you remove the captures using the command, To verify if ASA is dropping any packet - simple connectivity issues, access-list capi extended permit ip host 192.168.1.2 host 4.2.2.2, access-list capi extended permit ip host 4.2.2.2 host 192.168.1.2, capture capin interface inside access-list capi, capture capin interface inside match ip host 192.168.1.2 host 4.2.2.2, [this is possible in asa 8.0 and above and we do not need to be in config mode to put apply an capture], access-list capo extended permit ip host a.b.c.d host 4.2.2.2, access-list capo extended permit ip host 4.2.2.2 host a.b.c.d, capture capout interface outside access-list capo, capture capout interface outside match ip host a.b.c.d host 4.2.2.2, [Note that we are using the natted ip - so for capture use the ip addresses that you expect to see on the wire after all processing is done for egress interface and before any processing is done for ingress interface], We can also apply capture using ASDM and the below screen shots show the steps for that, 192.168.1.2 > 4.2.2.2: icmp: echo request, So you can see we have captured bidirectional traffic, If you want to see more details you can use the detailed keyword at the end, 000c.29d6.7dca 0026.0b09.420c 0x0800 74: 192.168.1.2 > 4.2.2.2: icmp: echo request (ttl 128, id 52241), 0026.0b09.420c 000c.29d6.7dca 0x0800 74: 4.2.2.2 > 192.168.1.2: icmp: echo reply (ttl 127, id 16992), 000c.29d6.7dca 0026.0b09.420c 0x0800 74: 192.168.1.2 > 4.2.2.2: icmp: echo request (ttl 128, id 52242), 0026.0b09.420c 000c.29d6.7dca 0x0800 74: 4.2.2.2 > 192.168.1.2: icmp: echo reply (ttl 127, id 16993), 000c.29d6.7dca 0026.0b09.420c 0x0800 74: 192.168.1.2 > 4.2.2.2: icmp: echo request (ttl 128, id 52243), 0026.0b09.420c 000c.29d6.7dca 0x0800 74: 4.2.2.2 > 192.168.1.2: icmp: echo reply (ttl 127, id 17008), 000c.29d6.7dca 0026.0b09.420c 0x0800 74: 192.168.1.2 > 4.2.2.2: icmp: echo request (ttl 128, id 52244), 0026.0b09.420c 000c.29d6.7dca 0x0800 74: 4.2.2.2 > 192.168.1.2: icmp: echo reply (ttl 127, id 17251), 0026.0b09.420d 0022.556d.f140 0x0800 74: a.b.c.d > 4.2.2.2: icmp: echo request (ttl 128, id 52241), 0022.556d.f140 0026.0b09.420d 0x0800 74: 4.2.2.2 > a.b.c.d: icmp: echo reply (ttl 127, id 16992), 0026.0b09.420d 0022.556d.f140 0x0800 74: a.b.c.d > 4.2.2.2: icmp: echo request (ttl 128, id 52242), 0022.556d.f140 0026.0b09.420d 0x0800 74: 4.2.2.2 > a.b.c.d: icmp: echo reply (ttl 127, id 16993), 0026.0b09.420d 0022.556d.f140 0x0800 74: a.b.c.d > 4.2.2.2: icmp: echo request (ttl 128, id 52243), 0022.556d.f140 0026.0b09.420d 0x0800 74: 4.2.2.2 > a.b.c.d: icmp: echo reply (ttl 127, id 17008), 0026.0b09.420d 0022.556d.f140 0x0800 74: a.b.c.d > 4.2.2.2: icmp: echo request (ttl 128, id 52244), 0022.556d.f140 0026.0b09.420d 0x0800 74: 4.2.2.2 > a.b.c.d: icmp: echo reply (ttl 127, id 17251).
