   Hosting data in different regional locations but not moving it for long periods of time describes:

   • Aa cold site.
   • Bdata at rest.
   • Con-site retention.
   • Doff-site storage.

   Show answer

   Answer: B

   Explanation

   The term that describes hosting data in different regional locations but not moving it for long periods of time is "data at rest". Data at rest refers to data that is not actively being used or transmitted, but is instead stored in a particular location or on a particular device. This can include data that is stored on hard drives, flash drives, or other storage media, as well as data that is stored in the cloud or on remote servers. Option A, a cold site, refers to a backup facility that is not operational until a disaster occurs and is typically used for disaster recovery purposes. Option C, on-site retention, refers to the practice of storing data on site, typically for regulatory or compliance purposes. Option D, off-site storage, refers to the practice of storing data in a location other than the primary data center, typically for backup or disaster recovery purposes.

   Which of the following will correctly map a script to a home directory for a user based on username?

   • A\\server\users$\username
   • B\\server\%username%
   • C\\server\FirstInitialLastName
   • D\\server\$username$

   Show answer

   Answer: B

   Explanation

   The correct option that will map a script to a home directory for a user based on the username is: B. \\server\%username% In this option, `%username%` is a variable that will be replaced with the actual username of the user. This allows for dynamic mapping based on the logged-in user's username. ~ChatGPT 4.0

4. Question 114 · 371 in bank

   A technician learns users are unable to log in to a Linux server with known-working LDAP credentials. The technician logs in to the server with a local account and confirms the system is functional, can communicate over the network, and is configured correctly. However, the server log has entries regarding Kerberos errors. Which of the following is the MOST likely source of the issue?

   • AA local firewall is blocking authentication requests.
   • BThe users have expired passwords.
   • CThe system clock is off by more than five minutes.
   • DThe server has no access to the LDAP host.

   Show answer

   Answer: C

   Explanation

   The most likely source of the issue in this scenario is that the system clock is off by more than five minutes. Kerberos is a network authentication protocol that relies on a shared secret between the client and server, as well as a trusted third-party server that provides authentication services. One of the requirements for proper functioning of Kerberos is that the clocks of the client, server, and third-party server must be synchronized within a certain tolerance. If the clocks are out of sync by more than five minutes, authentication requests will fail. Option A, a local firewall blocking authentication requests, is possible, but unlikely given that the server log has entries regarding Kerberos errors. Option B, users having expired passwords, would not result in Kerberos errors, but would result in authentication failure messages. Option D, the server having no access to the LDAP host, is possible, but unlikely given that the technician confirmed that the system is able to communicate over the network and is configured correctly.

   A senior administrator instructs a technician to run the following script on a Linux server: for i in {1..65536}; do echo $i; telnet localhost $i; done The script mostly returns the following message: Connection refused. However, there are several entries in the console display that look like this: 80 Connected to localhost - 443 Connected to localhost - Which of the following actions should the technician perform NEXT?

   • ALook for an unauthorized HTTP service on this server.
   • BLook for a virus infection on this server.
   • CLook for an unauthorized Telnet service on this server.
   • DLook for an unauthorized port scanning service on this server.

   Show answer

   Answer: A

   Explanation

   Don’t overthink this question. Ports 80 and 443 are for HTTP and HTTPS. Checking for an http service would be the obvious FIRST choice. Even though it is a telnet connection the ports are the default for http. Telnet can also connect to any port if there is any service running does not have to be a specific Telnet service.

   A VLAN needs to be configured within a virtual environment for a new VM. Which of the following will ensure the VM receives a correct IP address?

   • AA virtual router
   • BA host NIC
   • CAVPN
   • DA virtual switch
   • EA vNIC

   Show answer

   Answer: E

   Explanation

   E. A vNIC (virtual network interface card) is what connects a VM to a virtual network, and it is responsible for sending and receiving network traffic. When a VLAN needs to be configured within a virtual environment for a new VM, creating a vNIC with the correct VLAN configuration will ensure that the VM receives a correct IP address within that VLAN. The virtual switch is what connects the vNIC to the physical network, and a virtual router may be necessary if the VLAN is to communicate with other networks or the Internet, but neither of these options specifically ensures that the VM receives a correct IP address. AVPN (Amazon Virtual Private Network) is a networking solution provided by Amazon Web Services and is not relevant to this scenario unless the virtual environment is hosted on AWS. A host NIC (network interface card) is a physical network adapter on the host machine and is not directly related to configuring a VLAN for a virtual environment.

   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 ‘emacs’ on this server. Which of the following would BEST allow the user to find out which commands can be used?

   • Avisudo | grep userid
   • Bsudo -1 -U userid
   • Ccat /etc/passwd
   • Duserlist | grep userid

   Show answer

   Answer: B

   Explanation

   The BEST option to allow the user to find out which commands can be used is option B: sudo -1 -U userid. This command allows the user to run a shell with the privileges of the specified user (-U userid) while preserving their own environment (-i). This means that the user will be able to see the commands they are authorized to run, and also allows them to test running those commands as the authorized user. Option A (visudo | grep userid) runs the visudo command with the intention of displaying the sudoers file contents that have configuration options for the specified user, but it will not show the available commands. Option C (cat /etc/passwd) shows the contents of the /etc/passwd file, which contains user account information including usernames, user IDs, home directories, and login shells. However, it will not show the commands that the user can run. Option D (userlist | grep userid) does not seem to be a valid command and would not help the user find the available commands they can run.

8. Question 118 · 371 in bank

   A server administrator is connecting a new storage array to a server. The administrator has obtained multiple IP addresses for the array. Which of the following connection types is the server MOST likely using to connect to the array?

   • AeSATA
   • BUSB
   • CFC
   • DiSCSI

   Show answer

   Answer: D

   Explanation

   Based on the multiple IP addresses obtained for the storage array, the server is most likely using the iSCSI (Internet Small Computer System Interface) connection type to connect to the array. iSCSI is a protocol that allows SCSI commands to be sent over IP networks, and it typically uses IP addresses to identify and connect to storage devices over a network. Option A (eSATA) and B (USB) are both direct-attached storage (DAS) connection types that use a cable to connect the storage device directly to the server, rather than over a network. Option C (FC) is Fibre Channel, which is a network protocol for connecting storage devices to servers over a high-speed Fibre Channel network, but it typically uses Fibre Channel addresses (WWNs) rather than IP addresses to identify and connect to devices. Therefore, the most likely connection type in this scenario is iSCSI (Option D).

9. Question 119 · 371 in bank

   A newly installed server is accessible to local users, but remote users are unable to connect. Which of the following is MOST likely misconfigured?

   • AThe IP address
   • BThe default gateway
   • CThe VLAN
   • DThe subnet mask

   Show answer

   Answer: C

   Explanation

   If the default gateway is wrong, local users would also potentially have issues. If it's just the VLAN that is wrong, local users connected to that VLAN will have access, but no one outside that VLAN can reach the server. So it's more likely that it's a VLAN issue than it is a default gateway issue.

10. Question 120 · 371 in bank

    Users are able to connect to the wireless network, but they are unable to access the internet. The network administrator verifies connectivity to all network devices, and there are no ISP outages. The server administrator removes the old address leases from the active leases pool, which allows users to access the internet. Which of the following is MOST likely causing the internet issue?

    • AThe DHCP exclusion needs to be removed.
    • BThe DHGP scope is full.
    • CThe DHCP scope options are misconfigured.
    • DThe DHCP lease times are too short.
    • EThe DHCP reservations need to be configured.

    Show answer

    Answer: B

    Explanation

    This is most likely a typo.Based on the given information, the most likely cause of the internet issue is that the DHCP scope was full. DHCP (Dynamic Host Configuration Protocol) is a network protocol used to automatically assign IP addresses and other network configuration settings to devices on a network. A DHCP scope is a range of IP addresses that are available for assignment to devices on the network. If the DHCP scope is full, then new devices that try to connect to the network will not be able to get an IP address and other necessary network configuration settings from the DHCP server. In this case, removing old address leases from the active leases pool would free up some IP addresses for new devices to use, allowing them to access the internet. The other options (A, C, D, and E) could also cause DHCP-related issues, but they are less likely to be the cause of this specific problem based on the information given.
