   What is the architectural difference between the MAC address table and TCAM?

   • ATCAM entries are stored for 600 seconds, and MAC address table entries are kept for 200 seconds.
   • BTCAM entries are populated using the ARP table, and the MAC address table is populated dynamically from outgoing frames.
   • CTCAM entries consist of VLAN, port ID and source MAC Address, and MAC address table entries consist of source MAC address end port ID.
   • DTCAM entries are composed of value, mask, and result, and MAC address table entries are composed of value and results.

   Show answer

   Answer: D

   Explanation

   The correct answer is D: TCAM entries are composed of value, mask, and result, and MAC address table entries are composed of value and results. Here's why: TCAM (Ternary Content Addressable Memory): - Uses a three-component structure: 1. Value: The data to match 2. Mask: Determines which bits to compare 3. Result: The action to take when matched - Allows for wildcard matching - Optimized for fast lookups in networking devices MAC Address Table: - Uses a simpler two-component structure: 1. Value: MAC address 2. Result: Port number/interface - Direct one-to-one mapping - No masking capability needed Why other options are incorrect: A) The timing values are incorrect, and timing isn't an architectural difference B) This describes population methods, not architectural differences C) This incorrectly describes the components of both structures

   What is a difference between OSPF and EIGRP?

   • AOSPF is an advanced distance vector protocol. EIGRP is a link-state protocol.
   • BOSPF is a hybrid routing protocol. EIGRP is a link-state routing protocol.
   • COSPF uses the DUAL algorithm. EIGRP uses the SPF algorithm.
   • DOSPF uses an administrative distance of 110. EIGRP uses an administrative distance of 170.

   Answer: D

   Explanation

   OSPF: 1. link-state routing protocol 2. SPF 3. AD 110 EIGRP: 1. hybrid routing protocol 2. DUAL 3. AD: internal 90, external 170

   Select 2

   Which two methods are used to reduce the AP coverage area? (Choose two.)

   • AReduce channel width from 40 MHz to 20 MHz.
   • BReduce AP transmit power.
   • CEnable Fastlane.
   • DIncrease minimum mandatory data rate.
   • EDisable 2.4 GHz and use only 5 GHz.

   Show answer

   Answer: BD

   Explanation

   The transmit power of an AP affects the wireless coverage area and the maximum achievable signal-to-noise ratio. Proper configuration of transmit power is important for ensuring a wireless network is operating at its highest capacity. Reference: https://documentation.meraki.com/MR/Radio_Settings/Transmit_Power_and_Antenna_Configuration AP coverage area or the cell size, according to this Cisco link, there are two ways to reduce the AP coverage area: + Tuning Cell Size with Transmit Power + Tuning Cell Size with Data Rates Setting the transmit power level is a simplistic approach to defining the cell size, but that is not the only variable involved. The cell size of an AP is actually a compromise between its transmit power and the data rates that it offers. To design a wireless LAN for best performance, you would most likely need to disable some of the lower data rates. For example, you could disable the 1, 2, and 5.5 Mbps rates to force clients to use higher rates and better modulation and coding schemes. That would improve throughput for individual clients and would also benefit the BSS as a whole by eliminating the slower rates that use more time on a channel.

   SIMULATION - Guidelines - This is a lab item in which tasks will be performed on virtual devices. • Refer to the Tasks tab to view the tasks for this lab item. • Refer to the Topology tab to access the device console(s) and perform the tasks. • Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window. • All necessary preconfigurations have been applied. • Do not change the enable password or hostname for any device. • Save your configurations to NVRAM before moving to the next item. • Click Next at the bottom of the screen to submit this lab and move to the next question. • When Next is clicked, the lab closes and cannot be reopened. Topology -

   

   Tasks - OSPF is partially configured on all devices. Complete the configurations to achieve these results: 1. Configure R3 so that R20 is always designated as the BDR. 2. Configure R10 so that it does not participate in the DR/BDR election. Do not use the ip ospf network point-to-point command under the interface configuration to accomplish this task.

   This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.

   You can do this 2 ways ! router bgp 10 bgp router-id interface Loopback0 bgp log-neighbor-changes network 209.165.201.1 mask 255.255.255.255 network 209.165.201.2 mask 255.255.255.255 neighbor 209.165.200.226 remote-as 20 neighbor 209.165.202.129 remote-as 30 ! OR ! router bgp 10 bgp router-id 10.10.10.1 bgp log-neighbor-changes network 209.165.201.1 mask 255.255.255.255 network 209.165.201.2 mask 255.255.255.255 neighbor 209.165.200.226 remote-as 20 neighbor 209.165.202.129 remote-as 30 ! as it states "Configure eBGP using Loopback 0 for the router-id" I believe that: * bgp router-id interface Loopback0 would be the more correct answer, but both are still valid.
