N10-009 Exam Questions Tutorials

These four terms—avoidance, acceptance, mitigation, and transfer—are strategies used in risk management.

From Andrew Ramdayal’s guide:

“Risk in security refers to the potential for loss, damage, or destruction of assets or data due to a threat exploiting a vulnerability. Risk management strategies include avoidance, acceptance, mitigation, and transfer.”

Bottlenecking occurs when a device in the network (such as an IPS) cannot process traffic efficiently, resulting in a dramatic drop in throughput. The significant difference between the firewall's speed (48.8 Mbps down) and the end-user devices’ speeds (4.8 - 5.2 Mbps down) indicates a bottleneck caused by the IPS.

•Why not the other options?

•Packet loss (A) – Would typically cause connection timeouts, not just slow speeds.

•Channel overlap (C) – Affects only wireless networks, but the wired desktop is also experiencing slow speeds.

•Network congestion (D) – Would show fluctuations in both upload and download speeds, but upload speeds remain unaffected.

Availability refers to ensuring that data is accessible when needed. If a customer's data is accidentally deleted, it impacts availability, as the data can no longer be accessed.

=================

To redirect a network resource that has moved from a local network to a Software-as-a-Service (SaaS) solution, the network administrator needs to configure a DNS record that maps an alias to the new canonical name (hostname) of the SaaS provider’s server. The CNAME (Canonical Name) record is used to alias one domain name to another, effectively redirecting requests to the new hostname without needing to update the IP address directly. This is ideal for SaaS solutions, where the provider’s server hostname is used, and the IP address may change dynamically.

Why not TXT? A TXT record is used to store arbitrary text data, such as SPF records for email authentication or verification strings, not for redirecting resources.

Why not AAA? There is no such thing as an "AAA" record in DNS. This might be a typo for AAAA (IPv6 address record), but AAAA maps a hostname to an IPv6 address, not an alias.

Why not PTR? A PTR record is used for reverse DNS lookups (mapping an IP address to a hostname), not for redirecting a resource to a new hostname.
