NEW QUESTION 26
A company needs a redundant link to provide a channel to the management network in an incident response scenario. Which of the following remote access methods provides the BEST solution?

Out-of-band access

Split-tunnel connections

Virtual network computing

Remote desktop gateways

Out-of-band access is a remote access method that provides a separate, independent channel for accessing network devices and systems. Out-of-band access uses a dedicated network connection or a separate communication channel, such as a dial-up or cellular connection, to provide access to network devices and systems. This allows an administrator to access the management network even if the primary network connection is unavailable or impaired. Out-of-band access is a good solution for providing a redundant link to the management network in an incident response scenario because it can be used to access the network even if the primary connection is unavailable or impaired.

NEW QUESTION 38
A network administrator responds to a support ticket that was submitted by a customer who is having issues connecting to a website inside of the company network The administrator verities that the customer could not connect to a website using a URL Which of the following troubleshooting steps would be BEST for the administrator to take?

Check for certificate issues

Contact the ISP

Attempt to connect to the site via IP address

Check the NTP configuration.

Explanation
The best option for the administrator to take would be to attempt to connect to the site via IP address. This will help to determine if the issue is related to the website’s DNS address or if the site itself is not accessible.
Checking for certificate issues may be necessary, but this should be done after the administrator has attempted to connect to the site via IP address. Contacting the ISP is unnecessary since the issue is related to the website inside of the company network, and checking the NTP configuration is not relevant to this issue.
When a customer is having issues connecting to a website using a URL, one of the first troubleshooting steps a network administrator should take is attempting to connect to the site using the IP address of the website. This will help to determine if the issue is related to a DNS resolution problem or a connectivity problem. If the administrator is able to connect to the website using the IP address, then the issue may be related to a DNS problem. However, if the administrator is still unable to connect, then the issue may be related to a connectivity problem. In either case, further troubleshooting steps will be necessary. Checking for certificate issues or NTP configuration, and contacting the ISP would not be the BEST initial steps in this scenario.

NEW QUESTION 39
Which of the following uses the link-state routing algorithm and operates within a single autonomous system?

EIGRP

OSPF

RIP

BGP

Explanation

NEW QUESTION 40
A network administrator installed a new data and VoIP network. Users are now experiencing poor call quality when making calls. Which of the following should the administrator do to increase VoIP performance?

Configure a voice VLAN.

Configure LACP on all VoIP phones.

Configure PoE on the network.

Configure jumbo frames on the network.

Explanation
“Benefits of Voice VLAN
It ensures that your VoIP (Voice over Internet Phone) devices do not have to contend directly with all the broadcasts and other traffic from the data VLAN. A voice VLAN can simplify network configuration in some circumstances.”
https://community.fs.com/blog/auto-voip-vs-voice-vlan-what-s-the-difference.html Jumbo Frames
“When jumbo frames on a VoIP/UC network are enabled, it can cause the same kind of delay to your network transmissions.”
“VoIP uses will always not benefit from jumbo frame, as VoIP like gaming, is latency and time sensitive.
Jumbo Frame for Internet Purpose: You will not see any performance boost as the files that came across the internet does not support jumbo frame.”
https://www.ankmax.com/newsinfo/1358641.html#:~:text=VoIP%20uses%20will%20always%20not,does%20no
“To summarize this general best practice guide, you should NOT enable jumbo frame feature as a general home user.”

NEW QUESTION 41
Two remote offices need to be connected securely over an untrustworthy MAN. Each office needs to access network shares at the other site. Which of the following will BEST provide this functionality?

Client-to-site VPN

Third-party VPN service

Site-to-site VPN

Split-tunnel VPN

NEW QUESTION 42
A Wi-Fi network was originally configured to be able to handle interference from a microwave oven. The microwave oven was recently removed from the office. Now the network administrator wants to optimize the system to maximize the range of the signal. The main sources of signal degradation are the numerous cubicles and wooden walls between the WAP and the intended destination. Which of the following actions should the administrator take?

Implement CDMA.

Change from omni to directional.

Change the SSID.

Change the frequency.

– the microwave was already removed from the office
– the signal is OK now
– Notice that the question mentions “numerous cubicles and wooden walls” – meaning the signal now won’t have the interference as before
– KEY POINT: the admin wants to “maximize the range of the signal:”
Manually change the frequency to 2.4 GHz for more reliable speeds and range. While 5 GHz gives you a stronger signal, it doesn’t travel through walls or ceilings as well, so it doesn’t give you the best range.
“Microwave ovens: Older microwave ovens, which might not have sufficient shielding, can emit relatively high-powered signals in the 2.4GHz band, resulting in significant interference with WLAN devices operating in the 2.4GHz band.”
