Explanation:

ExplanationSymmetric encryption uses a single key that needs to be shared among the people who need to receive the message while asymmetric encryption uses a pair of public key and a private key to encrypt and decrypt messages when communicating.Asymmetric encryption takes relatively more time than the symmetric encryption.Diffie Hellman algorithm is an asymmetric algorithm used to establish a shared secret for a symmetric keyalgorithm. Nowadays most of the people uses hybrid crypto system i.e, combination of symmetric andasymmetric encryption. Asymmetric Encryption is used as a technique in key exchange mechanism to share secret key and after the key is shared between sender and receiver, the communication will take place using symmetric encryption. The shared secret key will be used to encrypt the communication.Triple DES (3DES), a symmetric-key algorithm for the encryption of electronic data, is the successor of DES (Data Encryption Standard) and provides more secure encryption then DES.Note: Although
"requires secret keys" option in this question is a bit unclear but it can only be assigned toSymmetric algorithm.

Explanation The 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

Explanation The HMAC-SHA-1-96 (also known as HMAC-SHA-1) encryption technique is used by IPSec to ensure that a message has not been altered. (-> Therefore answer "integrity" is the best choice). HMAC-SHA-1 uses the SHA-1 specified in FIPS-190-1, combined with HMAC (as per RFC 2104), and is described in RFC 2404.

Explanation
Endpoint protection platforms (EPP) prevent endpoint security threats like known and unknown malware.
Endpoint detection and response (EDR) solutions can detect and respond to threats that your EPP and other security tools did not catch.
EDR and EPP have similar goals but are designed to fulfill different purposes. EPP is designed to provide device-level protection by identifying malicious files, detecting potentially malicious activity, and providing tools for incident investigation and response.
The preventative nature of EPP complements proactive EDR. EPP acts as the first line of defense, filtering out attacks that can be detected by the organization's deployed security solutions. EDR acts as a second layer of protection, enabling security analysts to perform threat hunting and identify more subtle threats to the endpoint.
Effective endpoint defense requires a solution that integrates the capabilities of both EDR and EPP to provide protection against cyber threats without overwhelming an organization's security team.
