Refer to the exhibit. What is the next step to complete the implementation for the partial NAT configuration shown?
Answer: D
I believe also the D is correct. This dump is so dump. After reading 500 questions I believe it is such a waste of money!!

What is a syslog facility?
Answer: D
"The facility to which the message refers (for example, SNMP, SYS, and so forth). A facility can be a hardware device, a protocol, or a module of the system software. It denotes the source or the cause of the system message." https://www.cisco.com/c/en/us/td/docs/routers/access/wireless/software/guide/SysMsgLogging.html

DRAG DROP - Drag and drop the functions of DHCP from the left onto any of the positions on the right. Not all functions are used. Select and Place:
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below

Refer to the exhibit. A newly configured PC fails to connect to the internet by using TCP port 80 to www.cisco.com. Which setting must be modified for the connection to work?
Answer: B
I would go with B An IP address of 0.0. 0.0 indicates no server is specified. The pc already has an IP address, so we don't actually need a DHCP server to access the internet. Both the default gateway and the IP address use the same SM

Which QoS queuing method discards or marks packets that exceed the desired bit rate of traffic flow?
Answer: B
This one made me read the entire QOS chapter again (netacad module 3 chapter 9), because of the way the question is asked... "discards or (re)marks packets" -> definitely policing But it never buffers. So for me based on what you see in ccna it's defnitely not a Queuing method/algo, it's a congestion avoidance tool.

Which QoS per-hop behavior changes the value of the ToS field in the IPv4 packet header?
Answer: D
Yes it is correct. Marking is a method that you use to modify the QoS fields of the incoming and outgoing packets. The QoS fields that you can mark are IPprecedence and differentiated services code point (DSCP) in Layer 3. The QoS group is a label local to the system to which you can assign intermediate marking values. You can use the QoS group label to determine the egress scheduling. DSCP is the equivalent to ToS but it interprets the field differently. https://www.cisco.com/c/en/us/td/docs/dcn/nx-os/nexus9000/101x/configuration/qos/cisco-nexus-9000-nx-os-quality-of-service-configuration-guide-101x/m-configuring-marking.pdf https://linuxreviews.org/Type_of_Service_(ToS)_and_DSCP_Values

What is the function of FTP?
Answer: D
How does TFTP operate in a network?
Answer: C
Seems correct as a,b,d makes no sense. Block Number : The Block Number field on Data Packets starts with one and then increase sequentially by one for each new packets. This type of numbering allows TFTP applications to identify between new DATA packets and duplicates. https://www.omnisecu.com/tcpip/tftp-data-packet.php#:~:text=Block%20Number%20%3A%20The%20Block%20Number,from%200%20to%20512%20bytes.

Refer to the exhibit. Which plan must be implemented to ensure optimal QoS marking practices on this network?
Answer: A
The IP phone will mark the voice traffic at the phone, so trust this on SW1. The PC traffic will need to be marked at SW2. Marking is occurring as close to the edge as possible without client intervention. Option ‘A’ correctly identifies this.

How does QoS optimize voice traffic?
Answer: B
Key guidelines are Delay one way: 150ms or less Jitter: 30ms or less Loss: 1% or less From the official cert guide vol 2 Ch11.
