- Question
You need to stop DoS attacks in real time and have a log of anyone who has tried to attack your network. What should you do your network?
Options- A. Add more routers
- B. Use the auto secure command
- C. Implement IDS/IPS
- D. Configure Naggle
- Correct Answer
- Implement IDS/IPS
ExplanationImplementing Intrusion Detection Service and Intrusion prevention Service (IDS/IPS) will help notify you and stop attacks in real time.
- 1. Which command will configure a switch port to use the IEEE standard method of inserting VLAN membership information into Ethernet frames?
Options- A. Switch (config) #switchport trunk encapsulation ietf
- B. Switch (config) #switchport trunk encapsulation dot1q
- C. Switch (config-if) #switchport trunk encapsulation ietf
- D. Switch (config-if) #switchport trunk encapsulation dot1q Discuss
- 2. What is the purpose of Spanning Tree Protocol in a switched LAN?
Options- A. To provide a mechanism for network monitoring is switched environments
- B. To prevent routing loops in network with redundant paths
- C. To prevent switching loops in networks with redundant switched paths
- D. To manage the VLAN database across multiple switches Discuss
- 3. What four routed protocols are supported by EIGRP? Discuss
- 4. There are three possible routes for a router to reach a destination network. The first route is from OSPF with a metric of 782. The second route is from RIPv2 with a metric of 4. The third is from EIGRP with a composite metric of 20514560. Which route will be installed by the router in its routing table?
Options- A. RIPv2
- B. EIGRP
- C. OSPF
- D. All three Discuss
- 5. If your routing table has a static, a RIP, and an EIGRP route to the same network, which route will be used to route packets by default?
Options- A. Any available route
- B. RIP route
- C. Static route
- D. EIGRP route Discuss
- 6. How many non- overlapping channels are available with 802.11b?
Options- A. 3
- B. 12
- C. 23
- D. 40 Discuss
- 7. Which IEEE committee has been sanctioned by WAP and is called WPA2? Discuss
- 8. What device must be on your wired network when running an enterprise EAP solution? Discuss
- 9. You want to ping the loopback address of your IPv6 local host. What will you type?
Options- A. Ping 127.0.0.1
- B. Ping 0.0.0.0
- C. Ping ::1
- D. trace 0.0. :: 1 Discuss
- 10. Which type of address is used just like a regular public routable address in IPv4? Discuss

Correct Answer: Switch (config-if) #switchport trunk encapsulation dot1q
Explanation:
If you are on a 2950 switch, then the interface command is just swichport mode trunk since the 2050 can only run the IEEE 802.1q version. However, a 3550 can run both ISL and 802.1q, so you must also use the encapsulation command. The argument to choose 802.1q for a trunking protocol is dot1q.
Correct Answer: To prevent switching loops in networks with redundant switched paths
Explanation:
The Spanning Tree Protocol (STP) was designed to stop layer 2 loops. All Cisco switches have the STP on by default.
Correct Answer: The four routed protocols supported by EIGRP are IP, IPv6, IPX, and AppleTalk
Correct Answer: EIGRP
Explanation:
Only the EIGRP routes will be placed in the routing table because it has the lowest administrative distance (AD), and that is always used before metrics.
Correct Answer: Static route
Explanation:
Static routes have an administrative distance of 1 by default. Unless you change this, a static route will always be used over any other dynamically learned route. EIGRP has an administrative distance of 90, and RIP has an administrative distance of 120, by default
Correct Answer: 3
Explanation:
The IEEE 802.11b standard provides three non-overlapping channels.
Correct Answer: The IEEE 80211i standard has been sanctioned by WPA and is termed WPA version 2
Correct Answer: RADIUS Server
Correct Answer: Ping ::1
Explanation:
The loop back address with IPv4 is 127.0.0.1 . With IPv6, that address is ::1
Correct Answer: Global unicast
