Which of the following can help prevent unauthorized modifications to hardware when designing an MDF closet?
A. Lockable cabinets
B. Uninterruptable power supply
C. Port security
D. Microsegmentation
Show Answer
Correct Answer: A
Explanation: Lockable cabinets provide physical security for network equipment in an MDF (Main Distribution Frame) closet, helping prevent unauthorized physical access and hardware tampering or modification. A UPS provides power continuity, port security controls network access at switch ports, and microsegmentation is a logical network security technique rather than a physical hardware protection measure.
Question 222
After a networking intern plugged in a switch, a significant number of the users in a building lost connectivity. Which of the following is the most likely root cause?
A. VTP update
B. Port security issue
C. LLDP misconfiguration
D. Native VLAN mismatch
Show Answer
Correct Answer: A
Explanation: A VTP update is the most likely cause of widespread connectivity loss immediately after a new switch was connected. If the new switch participates in the same VTP domain with a higher configuration revision, it can overwrite the VLAN database across the domain, causing VLANs to disappear or change and disconnect many users simultaneously. Port security typically affects individual ports, LLDP misconfiguration is informational and does not normally cause broad outages, and a native VLAN mismatch usually affects trunk behavior rather than deleting VLAN configurations across the network.
Question 223
Which of the following used to store and deliver content to clients in a geographically distributed manner using edge servers?
A. Load balancer
B. CDN
C. DNS server
D. SAN
Show Answer
Correct Answer: B
Explanation: A Content Delivery Network (CDN) uses geographically distributed edge servers to cache, store, and deliver content closer to end users, reducing latency and improving performance. Load balancers distribute traffic, DNS resolves names to IP addresses, and SANs provide storage infrastructure rather than edge content delivery.
Question 224
Several users report poor performance when accessing shared drives on a file server named Filed. While troubleshooting the issue, the network administrator swaps the Ethernet connections between File01 and another server named File02. Shortly thereafter, users report issues with File02, but Filed is no longer an issue. Which of the following is most likely impacting performance?
A. Port security
B. Speed/duplex mismatch
C. PoE power budget reduction
D. Keep-alive beacon failure
Show Answer
Correct Answer: B
Explanation: The issue follows the switch port after the Ethernet connections are swapped, indicating the problem is tied to the network port/configuration rather than the server itself. A speed/duplex mismatch commonly causes poor throughput and excessive retransmissions while connectivity remains functional. Port security would typically block or restrict access rather than cause degraded performance, PoE is irrelevant for typical file servers, and keep-alive beacon failure does not match these symptoms.
Question 225
Which of the following can be used when a server at a remote site is physically unreachable?
A. OOB management
B. Crash cart
C. Jump box
D. Console
Show Answer
Correct Answer: A
Explanation: Out-of-band (OOB) management provides a separate management path to access and control a remote server even when the primary network is unavailable or the server is otherwise physically unreachable. A crash cart requires on-site physical access, a jump box depends on network connectivity, and a console alone typically refers to local console access unless reached through OOB management.
Question 226
SIMULATION
-
A network technician needs to resolve some issues with a customer's SOHO network. The customer reports that some of the PCs are not connecting to the network, while others appear to be working as intended.
INSTRUCTIONS
-
Troubleshoot all the network components.
Review the cable test results first, then diagnose by clicking on the appropriate PC and server. Type help in each terminal to view a list of available commands.
Identify any components with a problem and recommend a solution to correct each problem.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
Show Answer
Correct Answer: Insufficient information to determine the faulty components from the screenshots alone.
Explanation: This simulation requires viewing cable test results for every device and running terminal commands on the PCs/server (e.g. IP configuration, gateway, VLAN, DNS, ARP). The provided images do not include those diagnostics, so the specific faults and fixes cannot be identified reliably.
Question 227
SIMULATION
-
A network administrator receives a ticket stating there is a connectivity issue between the server and the storage devices. The administrator needs to identify any issues and implement the appropriate solutions.
INSTRUCTIONS
-
Click on each access and core switch. Enter commands into the terminal to identify any problems and select the appropriate resolutions. Type help in each terminal to view a list of available commands.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
Show Answer
Correct Answer: Access Switch 1: No problem found
Core Switch 1: No problem found
Access Switch 2: Disconnected interface → Check and replace cable/SFP
Explanation: From the provided static images alone, the actual simulation state cannot be verified because terminal command output is missing. The only visible topology suggests the storage-side link is the most likely affected path, but this is not certain without interface status/error output.
Question 228
A systems administrator installs multiple web servers and intends to use the First Hop Redundancy Protocol to control routing to the servers. Which of the following types of IP addresses should the administrator use to support this routing approach?
A. Virtual
B. Gateway
C. Static
D. Dynamic
Show Answer
Correct Answer: A
Explanation: First Hop Redundancy Protocols (such as HSRP, VRRP, and GLBP) provide a shared virtual IP address that hosts use as their default gateway. The active router answers for the virtual IP, allowing seamless failover if a router goes down. Therefore, the appropriate IP address type is a virtual IP address.
Question 230
A network administrator needs to disable all inbound and outbound telnet traffic in the network. Which of the following ports should the administrator disable?
A. 23
B. 53
C. 123
D. 443
Show Answer
Correct Answer: A
Explanation: Telnet uses TCP port 23 by default for inbound and outbound remote terminal sessions. Port 53 is DNS, port 123 is NTP, and port 443 is HTTPS.
Question 231
Which of the following should be included in an SLA?
A. Patches and bug fixes
B. Licensing
C. Inventory management
D. Stakeholders
Show Answer
Correct Answer: D
Explanation: An SLA typically defines the parties involved, their roles and responsibilities, service scope, performance metrics, escalation procedures, and remedies. Stakeholders are a standard component because the agreement identifies who is responsible for delivering and receiving the service. Patches and bug fixes may be covered in some software support SLAs but are not a universal required element of an SLA. Licensing and inventory management are generally handled in separate agreements or operational processes.
