Net+ Jason Dion Practice Tests (009)questions with
answers
You have been asked to recommend a capability to monitor all of the traffic entering
and leaving the corporate network's default gateway. Additionally, the company's
CIO requests to block certain content types before it leaves the network based on
operational priorities. Which of the following solution should you recommend to
meet these requirements? - CORRECT ANSWERS ✔✔Install a NIPS on the internal
interface and a firewall on the external interface of the router
**The firewall on the external interface will allow the bulk of the malicious inbound
traffic to be filtered before reaching the network. Then, the NIPS can be used to
inspect the traffic entering the network and provide protection for the network using
signature-based or behavior-based analysis. A NIPS is less powerful than a firewall
and could easily "fail open" if it is overcome with traffic by being placed on the
external interface. The NIPS installed on the internal interface would also allow
various content types to be quickly blocked using custom signatures developed by the
security team. We wouldn't want to place the NIPS on the external interface in the
correct choice for the same reasons. We also wouldn't choose to install a NIPS on
both the internal and external connections.
In adherence to standards for physical networking installations, what is the
recommended orientation for a server rack to optimize cooling efficiency? -
CORRECT ANSWERS ✔✔Port-side Exhaust
**This means that the exhaust ports of the networking equipment should face a
common aisle, allowing hot air to be expelled from the back of the rack.
,In a corporate network, Georgina, a network administrator, is deploying multiple
switches to ensure uninterrupted connectivity for critical services. However, during
routine maintenance on one of the core switches, she notices a temporary disruption
in traffic flow. To mitigate this issue and maintain seamless communication, which
protocol should she implement to provide redundancy for the default gateway? -
CORRECT ANSWERS ✔✔FHRP (First Hop Redundancy Protocol)
**achieves this by allowing multiple routers to work together as a single virtual
router, ensuring seamless failover in case of an active router failure
An administrator is upgrading the switches in the server room to support 10 Gbps of
throughput. The switch will need to take advantage of the existing Cat 6a lines that
run to each server. Which of the following Ethernet standards should be used to meet
this requirement? - CORRECT ANSWERS ✔✔10GBaseT
**SW,SR, and FX are all fiber
What is used to define how much bandwidth can be used by various protocols on the
network? - CORRECT ANSWERS ✔✔Traffic shaping (aka packet shaping)
**The manipulation and prioritization of network traffic to reduce the impact of
heavy users or machines from affecting other users. Traffic shaping is used to
optimize or guarantee performance, improve latency, or increase usable bandwidth
for some kinds of packets by delaying other kinds.
A network administrator is configuring a VLAN across multiple switches. The
administrator wants to configure the VLAN once and have that configuration
propagate to all of the network switches. Which of the following should the
administrator do? - CORRECT ANSWERS ✔✔Configure the switches to utilize VTP
, **VLAN Trunking Protocol (VTP) shares VLAN information to all switches in a
network. VTP enables you to configure the VLAN on a VTP server for centralized
configuration and management. When you make a change to the VLAN
configuration on a VTP server, the change is propagated to all switches in the VTP
domain.
Which of the following standards is commonly used for exchanging authentication
and authorization data between parties, facilitating single sign-on (SSO) across
different systems? - CORRECT ANSWERS ✔✔SAML (Security Assertion Markup
Language)
**designed for exchanging authentication and authorization data between trusted
parties, enabling SSO and secure access to multiple systems
A client reports that half of the office is unable to access a shared printer on the
network. Which of the following should the network technician use to troubleshoot
the issue? - CORRECT ANSWERS ✔✔Network diagrams
You are a network administrator tasked with configuring a new switch for a
company's expanded office space. The switch needs to handle data efficiently to
support both high-speed internet access and VoIP services. The office has a mix of
devices, some of which only support Fast Ethernet, while others are capable of
Gigabit Ethernet speeds. To optimize network performance and ensure compatibility
with all devices, you must carefully set the duplex and speed settings for each port on
the switch. Which of the following configurations should you apply to the port
connecting to a device that only supports Fast Ethernet to ensure optimal
performance? - CORRECT ANSWERS ✔✔Set the port to full-duplex mode with a
speed of 100 Mbps.
