QUESTION: 205

A new application server has been configured in the cloud to provide access to all clients within the network. On-site users are able to access all resources, but remote users are reporting issues connecting to the new application. The server administrator verifies that all users are configured with the appropriate group memberships.
Which of the following is MOST likely causing the issue?

Telnet connections are disabled on the server.
Role-based access control is misconfigured.
There are misconfigured firewall rules.
Group policies have not been applied.

Answer(s): C

Explanation:

This is the most likely cause of the issue because firewall rules can block or allow traffic based on source, destination, port, protocol, or other criteria. If the firewall rules are not configured properly, they can prevent remote users from accessing the cloud application server, while allowing on-site users to access it.

QUESTION: 206

A technician is monitoring a server and notices there is only one NIC plugged in. but the server has two. The NIC is oversaturated, and the technician would like to increase the available bandwidth.
Which of the following solutions would be the BEST option to increase the speed of this NIC?

Link aggregation
Heartbeat
Most recently used
Active-active

Answer(s): A

Explanation:

This is the best solution to increase the speed of the NIC because link aggregation is a technique that combines multiple physical network interfaces into a single logical interface. This can increase the bandwidth, redundancy, and load balancing of network traffic. Link aggregation requires both the server and the switch to support it and be configured accordingly.

QUESTION: 207

A user logs in to a Linux server and attempts to run the following command:
sudo emacs /root/file
However the user gets the following message:
User userid is not allowed to execute Temacs' on this server.
Which of the following would BEST allow the user to find out which commands can be used?

visudo I grep userid
sudo -1 -U userid
cat /etc/passwd
userlist I grep userid

Answer(s): B

Explanation:

This is the best command to find out which commands can be used by a user with sudo privileges because it lists the allowed and forbidden commands for a given user or role. The -l option stands for list, and the -U option specifies the user name. The output of this command will show what commands can be executed with sudo by that user on that server.

QUESTION: 208

Which of the following is the MOST secure method to access servers located in remote branch offices?

Use an MFAout-of-band solution.
Use a Telnet connection.
Use a password complexity policy.
Use a role-based access policy.

Answer(s): A

Explanation:

This is the most secure method to access servers located in remote branch offices because MFA stands for multi-factor authentication, which requires users to provide more than one piece of evidence to prove their identity. An out-of-band solution means that one of the factors is delivered through a separate channel, such as a phone call, a text message, or an email. This adds an extra layer of security and prevents unauthorized access even if a password is compromised.
