Question 1

Users cannot access a webserver and after the traffic is captured, the capture tool shows an ICMP packet that reports "communication administratively prohibited". What is the cause of this webserver access issue?
A) An access list along the path is blocking the traffic.
B) Users must authenticate on the webserver to access it.
C) A router along the path is overloaded and thus dropping traffic.
D) The traffic is not allowed to be translated with NAT and dropped.

Accepted Answer

An ICMP "communication administratively prohibited" message typically indicates that an access control list (ACL) or firewall rule is blocking the traffic.

Question 2

While developing a real-time VoIP application on a Cisco Webex Teams platform, users report that their voice gets chopped or parts of the conversation drops out. Which network constraint is impacting the application?

Accepted Answer

Jitter refers to the variation in packet arrival times, which can cause voice packets to arrive out of order or at irregular intervals, leading to choppy audio in real-time VoIP applications.

Question 3

Question 8

A 401 HTTP response code is returned when calling a REST API. What is the error state identified by this response code?
A) The server cannot process the request as it has detected an issue in the request syntax or body.
B) The request has not been accepted because it requires authentication.
C) The sever accepted the request but the client is not authorized for this content.
D) The server cannot find the requested resource because the path specified is incorrect.

Accepted Answer

A 401 HTTP response code indicates that the request requires user authentication. The client must authenticate itself to get the requested response.

Question 10

What is the function of an IP address in networking?
A) represents a network connection on specific devices
B) specifies the type of traffic that is allowed to roam on a network
C) specifies resource's location and the mechanism to retrieve it
D) represents the unique ID that is assigned to one host on a network

Accepted Answer

An IP address is a unique identifier assigned to each device on a network. It allows devices to communicate with each other and access resources on the network.

Question 11

What is used in Layer 2 switches to direct packet transmission to the intended recipient?
A) MAC address
B) IPv6 address
C) spanning tree
D) IPv4 address

Accepted Answer

Layer 2 switches use MAC addresses to direct packet transmission to the intended recipient within a local network.

Question 12

What are two advantages of YANG-based approaches for infrastructure automation? (Choose two.)
A) multi-platform vendor abstraction
B) compiles to executables that run on network devices
C) designed to reflect networking concepts
D) directly maps to JavaScript
E) command line driven interface

Accepted Answer

YANG provides multi-platform vendor abstraction, allowing for consistent management across different devices. It is also designed to reflect networking concepts, making it suitable for network configuration and management.

Question 13

What is the first development task in test-driven development?
A) Write code that implements a desired function.
B) Write a failing test case for a desired function.
C) Reverse engineer the code for a desired function.
D) Write a passing test case for existing code.

Accepted Answer

In test-driven development, the first step is to write a failing test case for the desired function. This helps to define the function's requirements and ensures that the subsequent code development is focused on passing this test.

Question 14

What is a benefit of using edge computing in an IoT implementation?

Question 15

Where is an IP packet routed if the packet does not match any routes in the routing table?
A) firewall
B) load balancer
C) central switch
D) default gateway

Accepted Answer

If an IP packet does not match any specific routes in the routing table, it is routed to the default gateway, which is a catch-all route for packets with no specific destination.

Question 16

What are two key capabilities of Cisco Finesse? (Choose two.)
