A network architect is developing documentation for an upcoming IPv4/IPv6 dual-stack implementation The architect wants to shorten the following IPv6 address: ef82:0000:00O0:000O:0O00:1ab1:1234:1bc2. Which of the following is the MOST appropriate shortened version?
Correct Answer:
D
The most appropriate shortened version of the IPv6 address ef82:0000:00O0:000O:0O00:1ab1:1234:1bc2 is ef82::1ab1:1234:1bc2. IPv6 addresses are 128-bit hexadecimal values that are divided into eight groups of 16 bits each, separated by colons. IPv6 addresses can be shortened by using two rules: omitting leading zeros within each group, and replacing one or more consecutive groups of zeros with a double colon (::). Only one double colon can be used in an address. Applying these rules to the given address results in ef82::1ab1:1234:1bc2.

A network security technician is designing a solution for a secure remote access scheme with the following requirements:
• The solution must allow for users at multiple locations to access corporate resources.
• The on-premises equipment will not handle non-corporate, resource-bound traffic.
Which of the following should the network security technician consider when designing the solution? (Select two).
Correct Answer:
DF
A client-to-site VPN and a split-tunnel VPN are the best options for designing a secure remote access scheme that meets the given requirements. A client-to-site VPN allows users at multiple locations to access corporate resources over the internet by creating a secure tunnel between their devices and a VPN concentrator on the corporate network1. A split-tunnel VPN allows the on-premises equipment to handle only the traffic that is destined for the corporate resources, while the non-corporate traffic is routed directly to the internet without passing through the VPN tunnel2. This reduces the bandwidth and processing load on the corporate network and improves the performance of the remote access.

A technician installed an 8-port switch in a user's office. The user needs to add a second computer in the office, so the technician connects both PCs to the switch and connects the switch to the wall jack. However, the new PC cannot connect to network resources. The technician then observes the following:
• The new computer does not get an IP address on the client's VLAN.
• Both computers have a link light on their NICs.
• The new PC appears to be operating normally except for the network issue.
• The existing computer operates normally.
Which of the following should the technician do NEXT to address the situation?

A technician is configuring a wireless access point in a public space for guests to use. Which of the following should the technician configure so that only approved connections are
allowed?
Correct Answer:
B
A captive portal is a web page that requires users to authenticate or accept terms of service before they can access the internet through a wireless access point. A captive portal can be used to control who can use the wireless network, limit the bandwidth or time of usage, or display advertisements or information. A captive portal is a common feature of public wireless networks, such as those in hotels, airports, cafes, or libraries. A captive portal can prevent unauthorized or malicious users from accessing the network or consuming network resources.
