Secure Real-Time Transport Protocol (SRTP) is a security protocol used to encrypt and authenticate the streaming of audio and video over IP networks. It ensures that the video streams from the IP cameras are both encrypted to prevent unauthorized access and authenticated to verify the integrity of the stream, making it the ideal choice for securing video surveillance.

The best answer is B. Sideloading.
Sideloading is the installation of an application from outside the official or authorized application store, often by directly installing a binary package or application file. This bypasses standard review and distribution controls.
Why the other options are incorrect:
A). JailbreakingJailbreaking removes or bypasses manufacturer or operating system restrictions, often on mobile devices. It may enable sideloading, but it is not the same thing as the act described.
C). Memory injectionMemory injection is a technique used to place code into another process's memory. It is unrelated to installing an app from an unauthorized source.
D). VM escapingVM escape is an attack in which code breaks out of a virtual machine into the host environment. It does not describe unauthorized app installation.
From a Security+ standpoint, bypassing the approved app store and directly installing a binary is the definition of sideloading.

Detailed Explanation:
Time-of-day restrictions limit access to corporate systems based on predefined schedules. This ensures employees can only access resources during their assigned work hours. Reference: CompTIA Security+ SY0-
701 Study Guide, Domain 3: Security Architecture, Section: "Access Control Models".

Detailed Explanation:Access control lists (ACLs) allow administrators to fine-tune file permissions by specifying which users or groups have access to a file and defining the level of access.

The correct answer is If the root certificate is installed because trust errors in SSL/TLS deployments most commonly occur when the certificate chain cannot be validated back to a trusted root certificate authority. In the Security+ SY0-701 cryptography and PKI objectives, trust is established through a chain of trust, beginning with a trusted root CA, followed by any intermediate CAs, and ending with the server's certificate.
In this scenario, the administrator has already confirmed that the certificate was issued by a legitimate CA and that the private key is valid. This eliminates common issues related to key mismatch or improper issuance.
The next logical step is to verify that the system (or the client systems connecting to it) trusts the CA that issued the certificate. If the root certificate-or required intermediate certificates-are missing from the trust store, clients will flag the certificate as untrusted even though it is otherwise valid.
Option A, checking wildcard configuration, is not relevant unless the certificate is being used for multiple subdomains, which is not indicated. Option B, validating the certificate signing request, would be unnecessary because the CA successfully issued the certificate. Option D, verifying the public key, is incorrect because the public key is embedded in the certificate and would already be validated as part of successful issuance.
The SY0-701 study guide highlights that certificate trust failures are frequently caused by incomplete certificate chains, missing root or intermediate certificates, or misconfigured trust stores. Ensuring that the correct root CA certificate is installed allows systems to verify the certificate's authenticity and establish secure communications.
In summary, when an SSL certificate is valid but not trusted, the most likely cause is a missing trusted root certificate, making option C the correct answer.
