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
A network administrator is implementing OSPF on all of a company's network devices. Which of the following will MOST likely replace all the company's hubs?
  1. A Layer 3 switch
  2. A proxy server
  3. A NGFW
  4. A WLAN controller
Correct answer: A
Explanation:
The OSPF (Open Shortest Path First) protocol is one of a family of IP Routing protocols, and is an Interior Gateway Protocol (IGP) for the Internet, used to distribute IP routing information throughout a single Autonomous System (AS) in an IP network.

Question 3
A network administrator discovers that users in an adjacent building are connecting to the company's guest wireless network to download inappropriate material.     
Which of the following can the administrator do to MOST easily mitigate this issue?
  1. Reduce the wireless power levels
  2. Adjust the wireless channels
  3. Enable wireless client isolation
  4. Enable wireless port security
Correct answer: A
Question 4
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 5
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 6
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 7
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 8
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 9
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 10
A fiber link connecting two campus networks is broken. Which of the following tools should an engineer use to detect the exact break point of the fiber link?
  1. OTDR
  2. Tone generator
  3. Fusion splicer
  4. Cable tester 
  5. PoE injector
Correct answer: A
Explanation:
An Optical Time Domain Reflectometer (OTDR) is a device that tests the integrity of a fiber cable and is used for the building, certifying, maintaining, and troubleshooting fiber optic systems.  Fusion Splicing is a preferred way to join two fibers together by using heat. Whether the fiber was broken or not long enough, a fusion splicer will make your job easier. You would do this after finding where the break is.
