📝 CCNA quiz R1 is using OSPF and receives two routes to the 10,0,1,0/24 network from two different neighbors. What parameter does R1 use to determine which route to insert into its routing table? a) Metric b) AD c) Prefix length d) Most specific match *I have to use commas in the IP address or LinkedIn interprets is as a suspicious link and blocks the post 🤷♂️ ➡ Answer & explanation on my channel's community tab: https://lnkd.in/gtQDSbZh #cisco #ccna #jeremysitlab #jitl

📝 CCNA quiz: R1's G0/0 interface has the IP address 192,168,1,1/24. Which of the following 'network' commands can be used to activate OSPF on the interface? a) network 192,168,0,0 0,0,0,255 area 0 b) network 192,168,1,1 0,0,0,0 area 0 c) network 192,168,1,0 0,0,0,0 area 0 *I have to use commas in the IP addresses or LinkedIn interprets them as links and blocks the post 🤷♂️ ➡ Answer & explanation on my channel's community tab: https://lnkd.in/gtQDSbZh #cisco #ccna #jeremysitlab #jitl

📝 CCNA quiz: A router learns three routes to the same destination network. What takes precedence when deciding which of the three routes will be inserted into the routing table? a) Longest prefix length b) AD c) Metric ➡ Answer & explanation on my channel's community tab: https://lnkd.in/gYC7Ks5w #cisco #ccna

Day 23 of my CCNA 200-301 journey! After skipping some videos on STP and Rapid Spanning Tree Protocol (covered those in my textbook), today I dove into EtherChannels. Essentially, it's link aggregation where multiple physical ports are combined into a single logical port—almost the opposite of VLANs. I learned about EtherChannel, specifically focusing on LACP (Link Aggregation Control Protocol), and practiced configuring it since it's a key topic for the exam. Another valuable tool for optimizing network performance! 🔗💡 #CCNA #EtherChannel #LACP #LinkAggregation #Networking #Cisco

C. spanning-tree portfast spanning-tree bpduguard enable For interface switches connecting to end devices like laptop and pc. Don't forget the switchport mode access. 

📝 CCNA quiz: You issue the following commands on a switch port: 'switchport trunk native vlan 11', switchport access vlan 10', 'switchport mode access'. When an untagged frame arrives on the port, which VLAN is the frame assigned to? a) VLAN 10 b) VLAN 11 ➡ Answer & explanation on my channel's community tab: https://lnkd.in/gtQDSbZh #cisco #ccna #jeremysitlab #jitl

📝 CCNA quiz: What is indicated by the IPv4 Total Length field? a) The length of the packet in bytes b) The length of the packet in 4-byte increments c) The length of the IPv4 header in bytes d) The length of the IPv4 header in 4-byte increments ➡️ Answer & explanation on my channel's community tab: https://lnkd.in/gtQDSbZh #cisco #ccna #jeremysitlab #jitl

B. Ip routing Do this before configuring any IP routes or IP addresses on a multilayer switch so you can do layer 3 commands.

📝 CCNA quiz When configuring static NAT with 'ip nat inside source static <address> <address>', which two addresses do you define in the command, and in which order? a) <inside-local> <outside-global> b) <inside-local> <outside-local> c) <inside-local> <inside-global> d) <inside-global> <inside-local> ➡ Answer & explanation on my channel's community tab: https://lnkd.in/gtQDSbZh #cisco #ccna #jeremysitlab #jitl
