Question 1282 · 1334 in bank
Refer to the exhibit. Which command set configures ROUTER-1 to allow Internet access for users on the 192.168.1.0/24 subnet while using 209.165.202.129 for Port Address Translation?
Show answer
Answer: D
Explanation
This question is a total mess - 2 same subnets on different router ports - impossible ! How can answer 'A' be correct when it defines such a dumb range - 192.168.ZERO.0 - 192.168.ONE.0 with netmask for 255 addresses !?! Examtopics - I will never pay you again !

Which IP header field is changed by a Cisco device when QoS marking is enabled?
Show answer
Answer: C
Explanation
Sorry I would go with answer C. The IPv4 Header has a 1 byte field called Type of Service, and DSCP lives inside that byte, that's why I think the best answer is C.

Question 1286 · 1334 in bank
Which DSCP per-hop forwarding behavior is divided into subclasses based on drop probability?
Show answer
Answer: C
Explanation
Expedited Forwarding (EF) The expedited forwarding (EF) per-hop behavior assures that any traffic class with EF's related DSCP is given highest priority and is not queued. EF provides low loss, latency, and jitter. The recommended DS codepoint for EF is 101110. A packet that is marked with 101110 receives guaranteed low-drop precedence as the packet traverses diffserv-aware networks en route to its destination. Use the EF DSCP when assigning priority to customers or applications with a premium SLA. Assured Forwarding (AF) The assured forwarding (AF) per-hop behavior provides four different forwarding classes that you can assign to a packet. Each forwarding class provides three drop precedences, as shown in Table 6–2. The various AF codepoints provide the ability to assign different levels of services to customers and applications. In the QoS policy you can prioritize traffic and services on your network when you plan the QoS policy. You can then assign different AF levels to the prioritized traffic.

Question 1287 · 1334 in bank
Select 2What are two features of the DHCP relay agent? (Choose two.)
Show answer
Answer: BD
Explanation
The DHCP relay agent itself does not assign anything locally or otherwise DNS or otherwise, so A is incorrect. It does minimize the number of DHCP servers because it means we don't need a DHCP server on every subnet, so B is correct. You actually can configure more than one IP helper command under an individual Layer 3 interface, so C is incorrect and D is correct.

Question 1288 · 1334 in bank
A DHCP pool has been created with the name CONTROL. The pool uses the next to last usable IP address as the default gateway for the DHCP clients. The server is located at 172.16.32.15. What is the next step in the process for clients on the 192.168.52.0/24 subnet to reach the DHCP server?
Show answer
Answer: A
Explanation
The question states that the pool has been created and that it uses the next to last usable IP address as the default gateway for the DHCP clients. So that already implies that B is not the answer. But just to confirm once and for all, 192.168.52.253 is NOT the last usable address, that would be 192.168.52.254. The answer is A because we need to configure a helper address since the DHCP server is on a different subnet.
