NEW QUESTION # 10
A network engineer is asked to configure a "site-to-site" Ipsec VPN tunnel. One of the last things that the engineer does is to configure an access list (access-list 1 permit any) along with the command ip nat inside source list 1 int s0/0 overload. Which functions do the two commands serve in this scenario?
- A. The command ip nat inside source list 1 int s0/0 overload disables "many-to-one" access for all devices on a defined segment to share a single IP address upon exiting the external interface.
- B. The command ip nat inside source list 1 int s0/0 overload provides "many-to-one" access for all devices on a defined segment to share a single IP address upon exiting the external interface.
- C. The command access-list 1 defines interesting traffic that is allowed through the tunnel.
- D. The command access-list 1 permit any defines only one machine that is allowed through the tunnel.
Answer: B
Explanation:
Configuring NAT to Allow Internal Users to Access the Internet Using Overloading
Note in the previous second configuration, the NAT pool "ovrld"only has a range of one address. The keyword overload used in the ip nat inside source list 7 pool ovrld overload command allows NAT to translate multiple inside devices to the single address in the pool.

NEW QUESTION # 17
A customer has restricted the AP and antenna combinations for a design to be limited to one model integrated antenna AP for carpeted spaces and one model external antenna AP with high gain antennas for industrial, maintenance, or storage areas. When moving between a carpeted area to an industrial area, the engineer forgets to change survey devices and surveys several APs. Which strategy will reduce the negative impact of the design?
- A. Deploy unsurveyed access points to the design.
- B. Resurvey and adjust the design.
- C. Increase the Tx power on incorrectly surveyed access points.
- D. Deploy the specified access points per area type.
Answer: B
Explanation:
The most effective way to address the issue is to resurvey the areas with the correct survey devices. This ensures that the design accurately reflects the performance characteristics of the specified access points for each area type, leading to a more reliable and efficient wireless network design tailored to each environment's specific needs.
NEW QUESTION # 18
An engineer must create data link redundancy for the company's Cisco Wireless LAN controller. The engineer has decided to configure LAG-based redundancy instead of port-based redundancy. Which three features of LAG-based redundancy influenced this decision? (Choose three.)
- A. All interface traffic passes as long as one port is up.
- B. Interface connection to two separate nonstacked switches is available.
- C. Full bandwidth of all links is available.
- D. The same port has multiple untagged dynamic interfaces.
- E. Ports are grouped into multiple LAGs.
- F. Packets are always sent out on the same port they are received on.
Answer: A,B,C
Explanation:
The decision to configure LAG-based redundancy is influenced by the following features:
* B. All interface traffic passes as long as one port is up: This ensures that the wireless LAN controller can continue to operate and manage traffic as long as at least one port in the LAG is functioning, providing a robust failover solution1.
* D. Interface connection to two separate nonstacked switches is available: LAG allows for connections to multiple switches, which can provide redundancy and higher availability compared to single switch connections1.
* E. Full bandwidth of all links is available: With LAG, the combined bandwidth of all active ports is available, enhancing the throughput capabilities of the wireless LAN controller1.

NEW QUESTION # 21
A wireless engineer is performing a post verification of a wireless network. Which two metrics does the engineer verify to ensure that the wireless network can support voice services? (Choose two.)
- A. The client device must have at least an -67 dBm RSSI.
- B. The rate of retransmitted packets must be 20 percent or below.
- C. The client device must have at least an -65 dBm RSSI.
- D. The rate of retransmitted packets must be 15 percent or below.
- E. The coverage area must have a noise floor that does not exceed -87 dBm.
Answer: A,C
Explanation:
Voice services on a wireless network require a strong and stable signal, as well as low interference and retransmission rates. An RSSI (Received Signal Strength Indicator) of at least -67 dBm is considered the minimum for acceptable voice quality, and -65 dBm is even better, providing a buffer for signal fluctuation. A noise floor of -87 dBm would be too high and could interfere with signal clarity. Retransmission rates should be kept as low as possible; 15% or below is a good target to ensure efficient communication.

NEW QUESTION # 25
An enterprise is using two wireless controllers to support the wireless network. The data centre is located in the head office Each controller has a corporate WLAN configured with the nameCopr-NET390595865WLC-1 and Copr-NET6837l638WLC-2. The APs are installed using a round-robin approach to load balance the traffic. What should be changed on the configuration to optimize roaming?
- A. Place the access points per floor on the same controller.
- B. Use the same WLAN name for the corporate network on both controllers.
- C. Use the same WLAN name for the corporate network on both controllers.
- D. Move all access points to one controller and use the other as N+1 HA.
