Question 66

The network's IDS is giving multiple alerts that unauthorized traffic from a critical application server is being sent to a known-bad public IP address.
One of the alerts contains the following information:
Exploit Alert
Attempted User Privilege Gain
2/2/07-3: 09:09 10.1.200.32
--> 208.206.12.9:80
This server application is part of a cluster in which two other servers are also servicing clients. The server administrator has verified the other servers are not sending out traffic to that public IP address. The IP address subnet of the application servers is 10.1.200.0/26. Which of the following should the administrator perform to ensure only authorized traffic is being sent from the application server and downtime is minimized? (Select two).

Correct Answer: B,F
The administrator should perform an antivirus scan on all servers within the cluster and reboot each server, and block access to 208.206.12.9 from all servers on the network. These actions will help to remove any malware that may have infected the application server and prevent any further unauthorized traffic to the known-bad public IP address. An antivirus scan can detect and remove malicious software that may be sending data to an external source, and a reboot can clear any temporary files or processes that may be related to the malware. Blocking access to 208.206.12.9 from all servers on the network can prevent any future attempts to communicate with the malicious IP address.

Question 67

A security analyst completed a port scan of the corporate production-server network. Results of the scan were then provided to a systems administrator for immediate action. The following table represents the requested changes:

The systems administrator created local firewall rules to block the ports indicated above. Immediately, the service desk began receiving calls about the internet being down. The systems administrator then reversed the changes, and the internet became available again. Which of the following ports on DNSSrv must remain open when the firewall rules are reapplied?

Correct Answer: E
Port 53 is the standard port for DNS (Domain Name System) queries and responses. DNS is a service that translates domain names (such as www.example.com) into IP addresses (such as 192.0.2.1) and vice vers a. DNS is essential for internet connectivity, as it allows users and applications to access websites and other online resources by using human-readable names instead of numerical addresses1.
The DNSSrv server is a DNS server that provides name resolution for the corporate network. If port 53 is blocked on this server, it will not be able to communicate with other DNS servers or clients, and the name resolution will fail. This will prevent users from accessing any websites or online services that rely on domain names, such as web browsers, email clients, or cloud applications. Therefore, port 53 must remain open on DNSSrv to allow DNS traffic to flow.

Question 68

A server administrator added a new drive to a server. However, the drive is not showing up as available. Which of the following does the administrator need to do to make the drive available?

Correct Answer: A
To make a new drive available on a server, the administrator needs to partition the drive first. Partitioning is a process that divides the drive into one or more logical sections that can be formatted and assigned drive letters or mount points. Partitioning can be done using tools such as Disk Management on Windows or fdisk on Linux. Creating a new disk quota would not help, as disk quotas are used to limit the amount of disk space that users or groups can use on a partition. Configuring the drive as dynamic would not help either, as dynamic disks are used to create volumes that span multiple disks or use RAID features. Setting the compression would not help, as compression is used to reduce the size of files on a partition.

Question 70

Which of the following BEST measures now much downtime an organization can tolerate Curing an unplanned outage?

Correct Answer: C
Explanation
RTO (Recovery Time Objective) is a measure of how much downtime an organization can tolerate during an unplanned outage. It is the maximum time allowed for restoring normal operations after a disaster. RTO is one of the key metrics for disaster recovery planning and testing. SLA (Service Level Agreement) is a contract that defines the expected level of service and performance between a provider and a customer. BIA (Business Impact Analysis) is a process that identifies and evaluates the potential effects of a disaster on critical business functions and processes. MTTR (Mean Time To Repair) is a measure of how long it takes to fix a failed component or system. References: https://parachute.cloud/rto-vs-rpo/
