Demo Questions

Question 1
Which of the following is the physical topology for an Ethernet LAN?
  1. Bus
  2. Ring
  3. Mesh
  4. Star
Correct answer: D
Explanation:
A star (hub-and-spoke) topology’s computers are connected to a central point with their own individual cables or wireless connections. You will often find that central spot inhabited by a device like a hub, a switch, or an access point.

Question 2
An engineer notices some late collisions on a half-duplex link. The engineer verifies that the devices on both ends of the connection are configured for half duplex. Which of the following is the MOST likely cause of this issue?
  1. The link is improperly terminated
  2. One of the devices is misconfigured
  3. The cable length is excessive
  4. One of the devices has a hardware issue
Correct answer: C
Explanation:
If duplex and RX/TX are correct, then late collisions most likely occur from cable lengths being too excessive.

Question 3
A network administrator is configuring a load balancer for two systems. Which of the following must the administrator configure to ensure connectivity during a failover?
  1. VIP
  2. NAT
  3. APIPA
  4. IPv6 tunneling
  5. Broadcast IP
Correct answer: A
Explanation:
You can use a virtual IP to achieve load balancing across multiple interfaces.

Question 4
A technician is troubleshooting a wireless connectivity issue in a small office located in a high-rise building. Several APs are mounted in this office. The users report that the network connections frequently disconnect and reconnect throughout the day. Which of the following is the MOST likely cause of this issue?
  1. The AP association time is set too low
  2. EIRP needs to be boosted
  3. Channel overlap is occurring
  4. The RSSI is misreported
Correct answer: B
Question 5
A network engineer configured new firewalls with the correct configuration to be deployed to each remote branch. Unneeded services were disabled, and all firewall rules were applied successfully. 
Which of the following should the network engineer perform NEXT to ensure all the firewalls are hardened successfully?
  1. Ensure an implicit permit rule is enabled
  2. Configure the log settings on the firewalls to the central syslog server
  3. Update the firewalls with current firmware and software
  4. Use the same complex passwords on all firewalls
Correct answer: C
Explanation:
Newer firmware and patches can often improve your existing firewall performance, resulting in faster speeds and better overall performance. In addition, newer firmware can provide additional features and security updates that can further improve the performance of your firewall.

Question 6
At which of the following OSI model layers would a technician find an IP header?
  1. Layer 1
  2. Layer 2
  3. Layer 3
  4. Layer 4
Correct answer: C
Explanation:
This should be at the network layer, as IP header are added to the packet at Layer 3.

Question 7
An engineer is configuring redundant network links between switches. Which of the following should the engineer enable to prevent network stability issues?
  1. 802.1Q
  2. STP
  3. Flow control 
  4. CSMA/CD
Correct answer: B
Explanation:
STP (Spanning Tree Protocol) - A switching protocol that prevents network loops by dynamically disabling links as needed.

Question 8
Which of the following can be used to centrally manage credentials for various types of administrative privileges on configured network devices?
  1. SSO
  2. TACACS+
  3. Zero Trust
  4. Separation of duties
  5. Multifactor authentication
Correct answer: B
Explanation:
Terminal Access Controller Access Control System (TACACS+) is often used in authenticating administrative access to routers and switches.

Question 9
A technician is assisting a user who cannot connect to a network resource. The technician first checks for a link light. According to troubleshooting methodology, this is an example of:
  1. using a bottom-to-top approach.
  2. establishing a plan of action.
  3. documenting a finding.
  4. questioning the obvious.
Correct answer: A
Explanation:
The Bottom-Up Troubleshooting Approach  The bottom-up troubleshooting approach also uses the OSI model as its guiding principle with the physical layer (bottom layer of the OSI seven-layer network model) as the starting point. In this approach, you work your way layer by layer up toward the application layer and verify that relevant network elements are operating correctly.  Checking the link light first to see if the physical layer is operational so it's bottom-to-top.

Question 10
Which of the following connector types would have the MOST flexibility?
  1. SFP
  2. BNC
  3. LC
  4. RJ45
Correct answer: A
Explanation:
SFP is a transceiver that allows for modular connection based on whatever is needed.  Example = Converting RJ45 to SC (copper to fiber), vice versa or some other combination needed.
