Options- A. 3
- B. 12
- C. 23
- D. 40
- Correct Answer
- 3
ExplanationThe IEEE 802.11b standard provides three non-overlapping channels.
- 1. 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 Discuss
- 2. 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
- 3. 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
- 4. What four routed protocols are supported by EIGRP? Discuss
- 5. 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
- 6. Which IEEE committee has been sanctioned by WAP and is called WPA2? Discuss
- 7. What device must be on your wired network when running an enterprise EAP solution? Discuss
- 8. 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
- 9. Which type of address is used just like a regular public routable address in IPv4? Discuss
- 10. You need to configure a router for a Frame Relay connection to a non-Cisco router. Which of the following commands will prepare the WAN interface of the router for this connection?
Options- A. Router (config-if) #encapsulation frame-relay q933a
- B. Router (config - if) #encapsulation frame-relay ansi
- C. Router (config - if) #encapsulation frame-relay ietf

Correct Answer: Implement IDS/IPS
Explanation:
Implementing Intrusion Detection Service and Intrusion prevention Service (IDS/IPS) will help notify you and stop attacks in real time.
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: 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
Correct Answer: Router (config - if) #encapsulation frame-relay ietf
Explanation:
If you have a Cisco router on one side of a Frame Relay network and a non-Cisco router on the otherside, you would need to use the Frame Relay encapsulation type of IETF. The default is Cisco encapsulation, which means that a Cisco router must be on both sides of the Frame Relay PVC.
