• Question 401:

  An administrator is replacing an existing WAP because the customer is reporting that the connection speeds are too slow. Which of the following should be installed?

  A. 802.11a
  B. 802.11b
  C. 802.11g
  D. 802.11n
  D. 802.11n

• Question 402:

  A network administrator connects two unmanaged switches together with a straight-through Ethernet cable. The administrator reviews the connection and notices that the uplinks are not on. Which of the following options offers the best solution for the issue?

  A. A rollover cable needs to be used.
  B. The switches needs to be rebooted after connecting.
  C. The ports need to be enabled.
  D. The ports need the IP address configured.
  E. A crossover cable needs to be used.
  E. A crossover cable needs to be used.

• Question 403:

  Which of the following protocols uses Dijkstra's algorithm to calculate the LOWEST cost between routers?

  A. RIP
  B. OSPF
  C. BGP
  D. EIGRP
  B. OSPF

  ---

  Explanation/Reference:

  OSPF stands for Open Shortest Path First and is a link-state routing protocol that uses Dijkstra's algorithm to calculate the lowest cost between routers. OSPF assigns a cost value to each link based on factors such as bandwidth, delay, or

  reliability, and builds a map of the network topology. OSPF then uses Dijkstra's algorithm to find the shortest path from each router to every other router in the network1. RIP stands for Routing Information Protocol and is a distance-vector

  routing protocol that uses hop count as the metric to find the best path. BGP stands for Border Gateway Protocol and is a path-vector routing protocol that uses attributes such as AS path, local preference, or origin to select the best route.

  EIGRP stands for Enhanced Interior Gateway Routing Protocol and is a hybrid routing protocol that uses a composite metric based on bandwidth, delay, load, and reliability.

• Question 404:

  An administrator wants to increase the availability of a server that is connected to the office network. Which of the following allows for multiple NICs to share a single IP address and offers maximum performance while providing fault tolerance in the event of a NIC failure?

  A. Multipathing
  B. Spanning Tree Protocol
  C. First Hop Redundancy Protocol
  D. Elasticity
  A. Multipathing

  ---

  Explanation/Reference:

  Multipathing. Multipathing allows multiple physical network connections to a server to share a single IP address, providing both increased performance and fault tolerance in the event of a NIC failure. This is commonly used for servers that require high availability and should be operational at all times. Spanning Tree Protocol (B) and First Hop Redundancy Protocol (C) are network protocols used to provide redundancy and failover capabilities for network switches and routers, but they do not apply to servers directly. Elasticity (D) refers to the ability of a system or application to automatically scale up or down to meet changing demands, and is not directly related to server availability or network connectivity.

• Question 405:

  A network administrator wants to check all network connections and see the output in integer form.

  Which of the following commands should the administrator run on the command line?

  A. netstat
  B. netstat -a
  C. netstat --e
  D. netstat --n
  D. netstat --n

• Question 406:

  A network administrator creates a new network, 10.10.0.0/24, on a DHCP server. The administrator wants to ensure that 10.10.0.10-10.10.0.15 are not allocated to other devices. Which of the following features should the administrator configure?

  A. Exclusion
  B. Reservation
  C. Scope
  D. Relay
  A. Exclusion

• Question 407:

  Which of the following network topologies contains a direct connection between every node in the network?

  A. Mesh
  B. Hub-and-spoke
  C. Star
  D. Point-to-point
  A. Mesh

  ---

  Explanation/Reference:

  Mesh Topology: In a mesh topology, every node is directly connected to every other node in the network. This provides high redundancy and fault tolerance, as communication can take multiple paths. Mesh topologies can be fully meshed (every node connected to every other node) or partially meshed (some nodes have direct connections to all other nodes).

• Question 408:

  A network technician is reviewing an upcoming project's requirements to implement laaS. Which of the following should the technician consider?

  A. Software installation processes
  B. Type of database to be installed
  C. Operating system maintenance
  D. Server hardware requirements
  D. Server hardware requirements

  ---

  Explanation/Reference:

  IaaS stands for Infrastructure as a Service, which is a cloud computing model that provides virtualized computing resources such as servers, storage, and networking over the Internet. When implementing IaaS, the network technician should consider the server hardware requirements, such as CPU, RAM, disk space, and network bandwidth, that are needed to run the applications and services on the cloud. The other options are not relevant to IaaS, as they are either handled by the cloud provider or by the end-user.

• Question 409:

  A store owner would like to have secure wireless access available for both equipment and patron use. Which of the following features should be configured to allow different wireless access through the same equipment?

  A. MIMO
  B. TKIP
  C. LTE
  D. SSID
  D. SSID

  ---

  Explanation/Reference:

  SSID stands for Service Set Identifier and is the name of a wireless network. A wireless access point (WAP) can support multiple SSIDs, which allows different wireless access through the same equipment. For example, the store owner can create one SSID for business equipment and another SSID for patron use, and assign different security settings and bandwidth limits for each SSID. MIMO stands for Multiple Input Multiple Output and is a technology that uses multiple antennas to improve wireless performance. TKIP stands for Temporal Key Integrity Protocol and is an encryption method for wireless networks. LTE stands for Long Term Evolution and is a cellular network technology.

• Question 410:

  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?

  A. Ensure an implicit permit rule is enabled.
  B. Configure the log settings on the firewalls to the central syslog server.
  C. Update the firewalls with current firmware and software.
  D. Use the same complex passwords on all firewalls.
  A. Ensure an implicit permit rule is enabled.
