   A network administrator is troubleshooting an issue on a newly configured college campus network. A Linux workstation can connect to the internet, but it fails to connect to the campus intranet, which is located on another campus. Which of the following commands should the administrator run next to troubleshoot the connection?

   • Aifconfig
   • Btraceroute
   • Cnmap
   • Ddig

   Show answer

   Answer: B

   Explanation

   The traceroute command (or tracert on Windows) is used to track the path packets take from the source to the destination. It helps identify where the connection is failing between the Linux workstation and the campus intranet, showing the path and any problematic hops. A. ifconfig: This command displays network interface configuration details but does not provide information about connectivity issues beyond the local network. C. nmap: This network scanning tool is used for discovering hosts and services on a network but is not primarily for troubleshooting connectivity issues. D. dig: This command queries DNS servers to troubleshoot domain name resolution issues but does not help with diagnosing routing or connectivity problems.

   Which of the following is the best way to remotely monitor who is accessing a secure data center?

   • AAccess control vestibule
   • BCameras
   • CEmployee training
   • DBiometrics

   Show answer

   Answer: B

   Explanation

   Cameras are the best way to remotely monitor who is accessing a secure data center. They can provide real-time video surveillance and records of individuals entering and exiting the facility, which is essential for security monitoring and auditing. A. Access control vestibule: While an access control vestibule is important for managing and controlling physical access, it does not offer real-time monitoring or recording of who is accessing the data center. C. Employee training: Training is crucial for ensuring employees understand security protocols but does not provide monitoring capabilities. D. Biometrics: Biometrics can control access to secure areas but do not offer remote monitoring of access events. They are more about authentication at the point of entry. One way how I think about it is by thinking if it would be a IDS or IPS just ask yourself: "Would Biometrics prevent someone walking in or to detect someone coming in?"

4. Question 814 · 871 in bank

   In a data center, data traffic that moves east-west is flowing between:

   • Athe top-of-rack and distribution switches.
   • Bthe server and the cloud.
   • Cthe top-of-rack and core switches.
   • Dtop-of-rack switches.

   Show answer

   Answer: D

   Explanation

   In a data center, data traffic typically moves through the following types: 1. **North-South Traffic**: - **Definition**: Traffic that flows into and out of the data center, typically between the data center and external networks, such as the internet or remote branch offices. - **Examples**: User requests from the internet to web servers, data replication between data centers, and remote backups. 2. **East-West Traffic**: - **Definition**: Traffic that moves laterally within the data center, between servers, storage systems, and other internal devices. - **Examples**: Communication between application servers, database queries from web servers to database servers, and data synchronization between storage systems. Understanding and managing these traffic types is crucial for optimizing data center performance, ensuring security, and maintaining efficient resource utilization.

   Which of the following can IoT devices most likely be connected to?

   • ARouter
   • BFirewall
   • CProxy server
   • DAccess point

   Show answer

   Answer: D

   Explanation

   D I’m gonna go with Access point y’all. Makes no sense in an enterprise environment for a device or any kind to be connected directly to a router. They first have to get connection through AP’s. I don’t think GPT is right here just my opinion.

6. Question 816 · 871 in bank

   A user reports that the internet seems slow on a workstation, but no other users have reported any issues. The server team confirms the servers are functioning normally. A technician suspects something specific to the user's computer is overutilizing bandwidth. Which of the following commands should the technician use to further investigate the issue?

   • Anmap
   • Btcpdump
   • Cnetstat
   • Dnslookup

   Show answer

   Answer: C

   Explanation

   Netstat provides a detailed list of active network connections and their associated ports on the workstation. This information helps identify which applications or services are using network resources and potentially consuming excessive bandwidth. By showing the state of these connections and the amount of data being transmitted, netstat allows the technician to diagnose bandwidth utilization issues effectively. B. tcpdump: While tcpdump captures detailed packet-level data and can be used for in-depth analysis of network traffic, it requires more complex interpretation and may be overkill for this initial troubleshooting step. A. nmap: This tool is used for network scanning and security auditing. It does not provide real-time information about bandwidth utilization or active connections on the workstation. D. nslookup: This command is used for DNS queries to resolve domain names. It does not provide information about network traffic or bandwidth usage.

7. Question 817 · 871 in bank

   Access to a datacenter should be individually recorded by a card reader even when multiple employees enter the facility at the same time. Which of the following allows the enforcement of this policy?

   • AMotion detection
   • BAccess control vestibules
   • CSmart lockers
   • DCameras

   Show answer

   Answer: B

   Explanation

   The devil is in the details, the question is essentially asking, why would it be possible for an individual to use a card reader, that would be a access control vestibule or mantrap. An individual would typically utilize a card reader if you want to access a particular room via a mantrap.

   Which of the following routing protocols uses bandwidth and delay as the primary metrics to calculate the best path?

   • AEIGRIP
   • BRIP
   • COSPF
   • DBGP

   Show answer

   Answer: A

   Explanation

   Enhanced Interior Gateway Routing Protocol (EIGRP) uses both bandwidth and delay as primary metrics to calculate the best path. EIGRP's metric calculation takes into account the bandwidth of the links and the delay associated with them to determine the most efficient route. B. RIP: Routing Information Protocol (RIP) primarily uses hop count as its metric. It does not consider bandwidth or delay in its path calculations. C. OSPF: Open Shortest Path First (OSPF) uses cost as its metric, which is typically based on the bandwidth of the links but does not explicitly consider delay. D. BGP: Border Gateway Protocol (BGP) uses path attributes like AS path and local preference rather than bandwidth and delay to determine the best path.

9. Question 819 · 871 in bank

   A new computer that was connected to the network reported an error of an Identical IP address with another computer. Both computers were configured for SLAAC. Which of the following is causing the error?

   • ARogue DHCP server
   • BDuplicate MAC addresses
   • CIncorrect router advertisement
   • DWrong VLAN assignment

   Show answer

   Answer: C

   Explanation

   In the context of SLAAC (Stateless Address Autoconfiguration), if two computers report an identical IP address error, the issue is most likely caused by an incorrect router advertisement. This happens because SLAAC relies on router advertisements to provide the network prefix. If the router sends incorrect or duplicate advertisements, it can lead to IP address conflicts as multiple devices may end up with the same address. A. Rogue DHCP server: A rogue DHCP server could cause issues with DHCP addresses, but SLAAC is not dependent on DHCP for IP assignment; it uses router advertisements. B. Duplicate MAC addresses: Duplicate MAC addresses are not related to IP address assignment issues but rather would cause other network problems, such as addressing conflicts at the link layer. D. Wrong VLAN assignment: Incorrect VLAN assignment might cause connectivity issues or misrouting of traffic but would not directly lead to IP address conflicts in the context of SLAAC. If I had to make second choice then I'd go with A.

10. Question 820 · 871 in bank

    A user is having trouble uploading files to a server. However, other users in the department are not experiencing this issue. The network administrator checks the access switch and sees multiple CRC errors on that user's switchport. Which of the following should the network administrator do first?

    • AReplace the uplink cable for the access switch.
    • BReplace the user's network cable.
    • CReplace the NIC for the user's PC.
    • DReplace the access switch.

    Show answer

    Answer: B

    Explanation

    Since the issue is isolated to that one user, and seeing as CRC errors are typically a problem on the physical layer, replacing their network cable would be the best option.
