350-701 Exam Dumps - Implementing and Operating Cisco Security Core Technologies (SCOR 350-701)

ExplanationExplanationCustomers must manage applications and data in PaaS.

ExplanationThe command crypto isakmp key cisco address 1.2.3.4 authenticates the IP address of the 1.2.3.4 peer by using the key cisco. The address of “0.0.0.0” will authenticate any address with this key

An active/active FlexVPN configuration allows for multiple routers or VRFs to act as hubs for different VPN groups, providing load balancing and redundancy1. This is useful when the VPN deployment has a large number of spokes or different security policies for different groups of spokes. DMVPN, on the other hand, only supports a single hub or a pair of hubs in active/standby mode for each VPN group2. This limits the scalability and flexibility of DMVPN deployments. Therefore, an engineer would opt for an active/active FlexVPN configuration as opposed to DMVPN when multiple routers or VRFs are required. References :=

A passphrase is a type of protection that encrypts RSA keys when they are exported and imported. A passphrase is a sequence of characters that the user enters to decrypt the key. The passphrase acts as a symmetric key that is used to encrypt and decrypt the RSA key with a symmetric algorithm, such as AES. This way, the RSA key is protected from unauthorized access or tampering when it is transferred or stored. A passphrase can also provide additional security by adding entropy to the RSA key generation process. A file, NGE, and nonexportable are not types of protection that encrypt RSA keys when they are exported and imported. A file is a container that stores the RSA key, but does not encrypt it. NGE stands for Next Generation Encryption, which is a set of cryptographic standards and algorithms that Cisco recommends, but it is not a specific type of protection. Nonexportable is a property that prevents the RSA key from being exported at all, but it does not encrypt it. References: RSA/Schannel Key BLOBs, Common Encryption Types, Protocols and Algorithms Explained, Implementing and Operating Cisco Security Core Technologies (SCOR) v1.0 (Module 5: Implementing Secure Communications with VPNs, Lesson 5.1: Implementing Site-to-Site VPNs, Topic 5.1.2: Implementing Site-to-Site VPNs with Pre-Shared Keys)

Anycast IP is a component of Cisco umbrella architecture that increases reliability of the service by allowing the same IP address to exist on multiple servers around the world. This way, the user’s request is automatically routed to the nearest and fastest data center, and failover is seamless in case of an outage. Anycast IP also reduces latency and improves performance by using BGP to select the shortest path to the destination12. References := 1: Why Cisco Umbrella uses anycast routing - Cisco Umbrella 2: Cisco Umbrella At a Glance

ExplanationExplanationStorm control prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on one of the physical interfaces. A LAN storm occurs when packets flood the LAN, creating excessive traffic and degrading network performance. Errors in the protocol-stack implementation, mistakes in network configurations, or users issuing a denial-of-service attack can cause a storm.By using the “storm-control broadcast level [falling-threshold]” we can limit the broadcast traffic on the switch.
